Updating Big Bang to version 2.22.0 using Helm Charts

Provide any steps possible used to reproduce the error (ideally in an isolated fashion).

Perform Big Bang update to v.2.22.0 by updating the helmrelease.yaml file

BigBang Version

What version of BigBang were you running? 2.21.1 --> 2.22.0

This can be retrieved multiple ways:

# via helm
helm ls -n bigbang

# via the deployed umbrella git tag
kubectl get gitrepository -n bigbang

When performing the Big Bang upgrade, the velero HelmRelease generates an error and fails to finish updating. The issue appears to be extraneous code in the Velero Helm chart 5.2.2-bb.1 at line 195

When attempting to override anything using a falsey value in a BB template that handles overrides using a sprig merge or mergeOverwrite, the value will remain unchanged.

For example, attempting to override the flux values for gitlab will only work when overridding using truthy values.

Given the following values

flux:
  upgrade:
    remediation:
      retries: 3
      remediateLastFailure: true
    rollback:
      timeout: 10m

addons:
  gitlab:
    flux:
      upgrade:
        remediation:
          retries: 0
          remediateLastFailure: false
    rollback:
      timeout: 5m

And this line in the current gitlab HelmRelease template

{{- $fluxSettingsGitlab := merge .Values.addons.gitlab.flux .Values.flux -}}

Will result in the following value for $fluxSettingsGitlab:

flux:
  upgrade:
    remediation:
      retries: 3
      remediateLastFailure: true
rollback:
  timeout: 5m

since 0 and false are both falsey and 5m is a string which is truthy.

The expected result would be

flux:
  upgrade:
    remediation:
      retries: 0
      remediateLastFailure: false
rollback:
  timeout: 5m

This behavior is not expected to change and is considered a feature in helm

This currently prevents turning off flux features that are defined as true or a positive integer at the top level that need to be disabled on a per app basis.

Bug

Description

If you define an IAM Role for S3 access and have Loki create a service account with the proper annotations you are unable to access the S3 buckets due to the requirement by the helm charts to have an ENDPOINT configured. Loki will not use the service account if it sees an endpoint configured and will require AccessKey which is strongly discouraged by AWS in favor of IRSA.
Currently Big Bang will force Minio if the endpoint is defined even if a region is defined. It should allow either a region and/or endpoint.

Note a workaround currently used by me is to define the endpoints under objectStorage and override this via the loki.existingSecretForConfig that has the config.yaml without the endpoint.

To reproduce this issue:
Create a IAM Role with an inline policy to allow S3 access to your buckets.
Configure Loki within BB as follows:

loki:
  enabled: true
  strategy: "scalable"
  objectStorage:
    endpoint: s3-us-gov-west-1.amazonaws.com
    region: us-gov-west-1
    bucketNames:
      chunks: mybucket
      ruler: mybucket
  values:
    serviceAccount:
      create: true
      annotations:
        eks.amazonaws.com/role-arn: "arn:aws-us-gov:iam::<redacted>:role/loki-s3-role"
    write:
      replicas: 1
      persistence:
        size: 50Gi
    read:
      replicas: 1
      persistence:
        size: 50Gi

The loki services will not be able to connect to the buckets. Note if you create a configuration as above and leave out the endpoint, the helm chart will not deploy. If you instead add

  values:
    loki:
      existingSecretForConfig: loki-config-sercet

And create the above secret that excludes the endpoint from the config it will succeed.

https://docs-bigbang.dso.mil/latest/about/

I believe this is about the docs compiler itself - not about BB itself. Seeing an about tab as a user of BB I would expect that it gives me info about BB rather than the tech used to create the site. This might still fit under some "nerd notes" or something.

For what it's worth I'd love to see the process for this, but the docs-compiler is not a public repo so there's nowhere to learn more :upside_down:

Version

2.20.0

Overview

The istio-system namespace is created with a mismatched name label (istio-controlplane).

Subsequently, the Istio network policies in subcharts (ex: Nexus) use a label selector for a namespace name that doesn't exist.

This can cause confusion when attempting to deploy a subchart independently of umbrella Bigbang as one might do for development or a very narrow production environment -- really, anywhere that Istio is installed separately from Bigbang.

Proposed Solution(s)

Unifying the name and labeling of the istio-system namespace by changing the name, or the label would improve system clarity. Though, it's worth noting that changing the label would also mean changing the label selector in almost every downstream Istio ingress/egress network policy. Changing the name is also likely to cause some confusion in the near-term, but is probably the simplest option.

A potential alternative (and my preferred approach) would be to expose the label selector name in each subchart as an input value (something like .Values.istio.controlplane-namespace) to be templated in the policy. This could be implemented gradually by making the default value in each subchart istio-controlplane. Doing so would allow us to leave the namespace's name and label unchanged while still enabling flexibility for independent subchart deployments.

Feature Request

Hello! Is it possible to expose the istio gateways.tls.credentialName value as an abstracted value?

Why

Currently Big Bang exposes the Istio gateway tls values as:

gateways:
    <name>:
      ingressGateway: <selector>
      hosts:
        - <hosts>
      tls:
        key: <gateway-key>
        cert: <gateway-cert>

This is a bit un-ideal if you want to pass a secret, say one generated by cert-manager, directly to gateway.tls.credentialName. To do that, you have to use the pass through method, which can start muddying the values file if you still need the abstracted gateway block as well. It's also not good practice to take the data from the custom secret and pass it to the tls.key and tls.cert fields, because another secret will just be generated by Big Bang with that data and passed to the .credentialName. So now there are 2 secrets with the same data, and in the case of cert-manager, this potentially makes the automatic rotation more complicated.

Proposed Solution

Add credentialName to exposed values like so:

gateways:
    <name>:
      ingressGateway: <selector>
      hosts:
        - <hosts>
      tls:
        key: <gateway-key>
        cert: <gateway-cert>
        credentialName: <name of tls secret>

then in https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/templates/istio/values.yaml
on lines 122 and 139 -- credentialName: {{ $index }}-{{ $name }}-cert / credentialName: {{ $name }}-cert
add a condition to check if $servervalues has credentialName and use that if found. There shouldn't be a need to edit https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/templates/istio/secret-tls.yaml since this shouldn't get generated if the user does not pass tls.key and tls.cert.

Feature Request

Why

Currently, the only way to import Big Bang charts (https://registry1.dso.mil/harbor/projects/133/repositories) into an airgapped enironment is to either scrape them from Harbor or manually download each chart. This is time consuming and the manual collection sometimes results in missing charts due to human error.

Proposed Solution

Provide a charts.tar.gz file similar to the git repositories (repositiories.tar.gz) and images (images.tar.gz) as a single file that can be pulled from S3 and imported into an airgapped environment.

Bug

Description

During a K8s upgrade, we discovered that our vault-vault-1 and vault-vault-2 pods were in a crashloopbackoff due to not being able to find the mounted SA token. I believe the issue stems from the kvyerno policy update-automountserviceaccounttokens. In the bb chart, i believe the issue is from this line. It should be vault-vault-* instead of just for vault-vault-1

Feature Request

Include Wrapper chart version in the release's package-images.yaml artifact.

Why

While there are no images in the wrapper chart, it is still beneficial to have the version of the chart in this release artifact in order to determine what version of the chart is included with the release.

Proposed Solution

Include a section in this file for the wrapper and have the list of images empty

  wrapper:
    version: "0.4.1"
    images: []

This would allow someone to determine what version of the wrapper chart (and any other chart) is required programmatically without checking out the commit associated with the release and parsing the chart values.

registry1.dso.mil/ironbank/opensource/postgres/postgresql12:12.18

The image is missing in the images.tar.gz and the images.txt. This image is needed for mattermost.

Bug

Description

The BB level value of networkPolicies.controlPlaneCidr passes down to app netpols via default values per app in their respective BB template subdirectories, but gitlab-runner is missing this default value here.

This is easy to mitigate in the meantime with addons.gitlabRunner.values.networkPolicies.controlPlaneCidr, but still a minor bug:

addons:
  gitlabRunner:
    enabled: true
    values:
      networkPolicies:
        controlPlaneCidr: 172.18.0.0/24

Also, the associated network policy includes a rule to allow all traffic to the gitlab namespace, but all other applications have a dedicated kube-api egress and this one should as well, as the current multi-element rule allows all traffic to the gitlab namespace or the default cidr (0.0.0.0/0 if not configured directly in the gitlab runner values).

Suggested action is to fix the gitlab runner BB level values, break the netpol into its own dedicated kube api netpol and create a new netpol for gitlab-runner > gitlab communication. Below was tested and worked fine for us:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  annotations:
    meta.helm.sh/release-name: gitlab-runner
    meta.helm.sh/release-namespace: gitlab-runner
  labels:
    app.kubernetes.io/managed-by: Helm
    helm.toolkit.fluxcd.io/name: gitlab-runner
    helm.toolkit.fluxcd.io/namespace: bigbang

          app: webservice
  podSelector:
    matchLabels:
      app: gitlab-runner
  policyTypes:
  - Egress

This policy enforces traffic to be destined to the gitlab namespace and pods with the app: webservice label which I believe is all gitlab-runner needs.

Mostly opening this issue for awareness that Ironbank MetalLB images exist now - https://repo1.dso.mil/dsop/opensource/metallb

It would probably be good for Big Bang to adopt these in the dev script and CI deployments. There would be changes required to make this work:

• securitycontext needs to be different to use these images
• auth would need to be provided for registry1 in pipelines/dev script when setting up metallb

Hi BB team-
I recently setup BB on GCP and wanted to provide some feedback to your documentation that might help future users. Please feel free to take it or leave it. Thanks!

1. The docs mention a "Fork" button, but there is no "Fork" button on the BigBang Gitlab repo page. You need to download the repo as a tar.gz file and upload to your own repo in your Gitlab instance instead.

2. If using a GCP KMS key, you can skip the section: "Create GPG Encryption Key". Instead, in your .sops.yaml file (note - this is a hidden file at the root of this directory) use this configuration instead
   of the GPG config:

creation_rules:
  - encrypted_regex: '^(data|stringData)$'
    gcp_kms: <gcp resource name of key>

Key resource name should look like: projects/{PROJECT_ID}/locations/global/keyRings/{KEY_RING_NAME}/cryptoKeys/{KEY_NAME}_**

If you get errors about the key not working, try re-logging in to GCP:

gcloud auth application-default login

And make sure you have the right project set:

gcloud config set project <project_id>

Also make sure you have these IAM roles on your GCP account:

roles/container.admin  
roles/iam.serviceAccountAdmin  

The KMS key also needs IAM permissions, and needs to be linked back to the flux-controller in the cluster. You need to create a service account and role binding, then manually annotate it:

kubectl annotate serviceaccount kustomize-controller --namespace flux-system iam.gke.io/gcp-service-account=flux-service-account@<project_id>.iam.gserviceaccount.com

GCP uses Workload Identity to allow the flux-controller to use the service account, good references for this setup are here. Make sure you enable Workload Identity on the cluster nodes:
GCP Docs
Medium Article

3. When encrypting the bigbang-dev-cert.yaml file with SOPS as mentioned in the documentation, it creates an encrypted secrets file, but the original file is not deleted. I recommend mentioning the need to delete this file so secrets aren't committed an I'd recommend decrypting and encrypting in place:

sops -d --in-place base/secrets.enc.yaml
sops -e --in-place base/secrets.enc.yaml

4. When creating the private-git secret, the docs say to use Repo1 username and password, but if you are using your own git repo outside of Repo1, then it's not Repo1 and I'd just make that more clear.

Bug

Description

We noticed that after every bigbang upgrades, past metrics are missing from Grafana dashboards and Prometheus, and we had to either revert back to the old version or delete all the Network Policies in the monitoring namespace in order for the metrics to show up again.

we tried upgrading from Bigbang 2.4 -> 2.5, and bigbang 2.18 -> 2.19, both shows the same issue

BigBang Version

2.18.0

Bug

Description

Describe the problem, what were you doing when you noticed the bug?

I am attempting to use the package package, and the domain variable is not passed down from the main values.yaml file we pass. This causes the VirtualService we specify in our chart to not have the correct domain set.

See the example here: https://repo1.dso.mil/dsop/radiusmethod/socketzero/receiver/-/blob/development/README.md?ref_type=heads

The workaround is to set a domain at the package level, but shouldn't be necessary I believe.

This can cause confusion when attempting to deploy a subchart independently of umbrella Bigbang as one might do for development or a very narrow production environment -- really, anywhere that Istio is installed separately from Bigbang.

Proposed Solution(s)

Unifying the name and labeling of the istio-system namespace by changing the name, or the label would improve system clarity. Though, it's worth noting that changing the label would also mean changing the label selector in almost every downstream Istio ingress/egress network policy. Changing the name is also likely to cause some confusion in the near-term, but is probably the simplest option.

A potential alternative (and my preferred approach) would be to expose the label selector name in each subchart as an input value (something like .Values.istio.controlplane-namespace) to be templated in the policy. This could be implemented gradually by making the default value in each subchart istio-controlplane. Doing so would allow us to leave the namespace's name and label unchanged while still enabling flexibility for independent subchart deployments.

Bug

Description

specifying an egressGatway similar to ingressGateways leads to a schema validation error because the logic to support that in the umbrella chart is not present. Ensure we can supply istio.egressGateways via the umbrella chart and ensure it makes it through to the istio chart.

Hi BB team-
I recently setup BB on GCP and wanted to provide some feedback to your documentation that might help future users. Please feel free to take it or leave it. Thanks!

1. The docs mention a "Fork" button, but there is no "Fork" button on the BigBang Gitlab repo page. You need to download the repo as a tar.gz file and upload to your own repo in your Gitlab instance instead.

2. If using a GCP KMS key, you can skip the section: "Create GPG Encryption Key". Instead, in your .sops.yaml file (note - this is a hidden file at the root of this directory) use this configuration instead
   of the GPG config:

creation_rules:
  - encrypted_regex: '^(data|stringData)$'
    gcp_kms: <gcp resource name of key>

Key resource name should look like: projects/{PROJECT_ID}/locations/global/keyRings/{KEY_RING_NAME}/cryptoKeys/{KEY_NAME}_**

If you get errors about the key not working, try re-logging in to GCP:

gcloud auth application-default login

And make sure you have the right project set:

gcloud config set project <project_id>

Also make sure you have these IAM roles on your GCP account:

roles/container.admin  
roles/iam.serviceAccountAdmin  

The KMS key also needs IAM permissions, and needs to be linked back to the flux-controller in the cluster. You need to create a service account and role binding, then manually annotate it:

kubectl annotate serviceaccount kustomize-controller --namespace flux-system iam.gke.io/gcp-service-account=flux-service-account@<project_id>.iam.gserviceaccount.com

GCP uses Workload Identity to allow the flux-controller to use the service account, good references for this setup are here. Make sure you enable Workload Identity on the cluster nodes:
GCP Docs
Medium Article

3. When encrypting the bigbang-dev-cert.yaml file with SOPS as mentioned in the documentation, it creates an encrypted secrets file, but the original file is not deleted. I recommend mentioning the need to delete this file so secrets aren't committed an I'd recommend decrypting and encrypting in place:

sops -d --in-place base/secrets.enc.yaml
sops -e --in-place base/secrets.enc.yaml

4. When creating the private-git secret, the docs say to use Repo1 username and password, but if you are using your own git repo outside of Repo1, then it's not Repo1 and I'd just make that more clear.

Feature Request

Why

Currently, the only way to import Big Bang charts (https://registry1.dso.mil/harbor/projects/133/repositories) into an airgapped enironment is to either scrape them from Harbor or manually download each chart. This is time consuming and the manual collection sometimes results in missing charts due to human error.

Proposed Solution

Provide a charts.tar.gz file similar to the git repositories (repositiories.tar.gz) and images (images.tar.gz) as a single file that can be pulled from S3 and imported into an airgapped environment.

Bug

Description

We noticed that after every bigbang upgrades, past metrics are missing from Grafana dashboards and Prometheus, and we had to either revert back to the old version or delete all the Network Policies in the monitoring namespace in order for the metrics to show up again.

we tried upgrading from Bigbang 2.4 -> 2.5, and bigbang 2.18 -> 2.19, both shows the same issue

BigBang Version

2.18.0

Feature Request

Why

We wanted to configure Gitlab users based on the Keycloak group. Based on Gitlab doc (https://docs.gitlab.com/ee/administration/auth/oidc.html?tab=Linux+package+%28Omnibus%29#administrator-groups), we have to configure Gitlab to identify what to look for in the Keycloak response. This is currently set as the secret (https://repo1.dso.mil/big-bang/bigbang/-/blob/2.1.0/chart/templates/gitlab/secret-sso.yaml?ref_type=tags#L33) in Bigbang, but it does not have the capability as of now. Request to provide the option to add additional config to the secret. Example below:

name: "openid_connect",
label: "Provider name",
args: {
  name: "openid_connect",
  scope: ["openid","profile","email"],
  response_type: "code",
  issuer: "<your_oidc_url>",
  discovery: true,
  client_auth_method: "query",
  uid_field: "<uid_field>",
  client_options: {
    identifier: "<your_oidc_client_id>",
    secret: "<your_oidc_client_secret>",
    redirect_uri: "<your_gitlab_url>/users/auth/openid_connect/callback",
    gitlab: {
      groups_attribute: "groups",
      admin_groups: ["Admin"]
    }
  }
}

}

Provide any steps possible used to reproduce the error (ideally in an isolated fashion).

    }

If your proposed solution _changes_ the existing behavior of a feature, please outline why your approach is recommended/better.

See MR where this is shown happening in CI: https://repo1.dso.mil/big-bang/bigbang/-/merge_requests/3749

Locally it seemed like the issue was istiod getting blocked by kyverno policies for non-root group and this is captured in the events as well - https://repo1.dso.mil/big-bang/bigbang/-/jobs/30819829/artifacts/file/events.txt

I haven't identified the exact issue, but it looks like TID is one minor version ahead of the upstream/default istio (1.20 v 1.19). I couldn't find any release notes indicating a change in this minor version but it's a bit hard to identify changes in the operator since its less supported now.

Maybe this is a separate issue but I don't believe that TID/enterprise is tested in any of the pipelines, which seems problematic?

Bug

Description

The BB level value of networkPolicies.controlPlaneCidr passes down to app netpols via default values per app in their respective BB template subdirectories, but gitlab-runner is missing this default value here.

This is easy to mitigate in the meantime with addons.gitlabRunner.values.networkPolicies.controlPlaneCidr, but still a minor bug:

addons:
  gitlabRunner:
    enabled: true
    values:
      networkPolicies:
        controlPlaneCidr: 172.18.0.0/24

Also, the associated network policy includes a rule to allow all traffic to the gitlab namespace, but all other applications have a dedicated kube-api egress and this one should as well, as the current multi-element rule allows all traffic to the gitlab namespace or the default cidr (0.0.0.0/0 if not configured directly in the gitlab runner values).

Suggested action is to fix the gitlab runner BB level values, break the netpol into its own dedicated kube api netpol and create a new netpol for gitlab-runner > gitlab communication. Below was tested and worked fine for us:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  annotations:
    meta.helm.sh/release-name: gitlab-runner
    meta.helm.sh/release-namespace: gitlab-runner
  labels:
    app.kubernetes.io/managed-by: Helm
    helm.toolkit.fluxcd.io/name: gitlab-runner
    helm.toolkit.fluxcd.io/namespace: bigbang
  name: egress-runner-to-webservice
  namespace: gitlab-runner
spec:
  egress:
  - to:
    - namespaceSelector:
        matchLabels:
          app.kubernetes.io/name: gitlab
      podSelector:
        matchLabels:
          app: webservice
  podSelector:
    matchLabels:
      app: gitlab-runner
  policyTypes:
  - Egress

This policy enforces traffic to be destined to the gitlab namespace and pods with the app: webservice label which I believe is all gitlab-runner needs.

BigBang Version

2.19.2 but likely an issue since the migration of gitlab-runner to its own namespace.

Mostly opening this issue for awareness that Ironbank MetalLB images exist now - https://repo1.dso.mil/dsop/opensource/metallb

It would probably be good for Big Bang to adopt these in the dev script and CI deployments. There would be changes required to make this work:

• securitycontext needs to be different to use these images
• auth would need to be provided for registry1 in pipelines/dev script when setting up metallb

https://repo1.dso.mil/big-bang/bigbang/-/releases/2.16.0

While the non-root-user policy being switched to enforce was mentioned, it was a very short mention and not included under upgrade notices. From the perspective of someone scanning these release notes it could be easily missed and it feels a bit "hidden" in the other details. Contrast these two:

2.16.0: This release sets Kyverno's require-non-root-user policy setting to Enforce. See this MR for more details

2.18.0:

• KyvernoPolicies:

  • The policy require-non-root-group is now set to enforce. All BigBang provided packages have exceptions or configuration in place to satisfy this requirement. Non-BigBang deployments will need to ensure they are setting a securityContext.runAsGroup value or an exception will need to be added.

  • You can use the following values or ensure a Kyverno PolicyException resource is present in your app templates:

    kyvernoPolicies:
      values:
        policies:
          require-non-root-group:
            exclude:
              any:
              - resources:
                  namespaces:
                  - NAMESPACE
                  names:
                  - POD-NAME-*
    ...

It would be great to retroactively edit 2.16.0 to place this under upgrade notices and more clearly articulate what might be required to ensure my apps on top of Big Bang still deploy.

Feature Request

Include Wrapper chart version in the release's package-images.yaml artifact.

Why

While there are no images in the wrapper chart, it is still beneficial to have the version of the chart in this release artifact in order to determine what version of the chart is included with the release.

Proposed Solution

Include a section in this file for the wrapper and have the list of images empty

  wrapper:
    version: "0.4.1"
    images: []

This would allow someone to determine what version of the wrapper chart (and any other chart) is required programmatically without checking out the commit associated with the release and parsing the chart values.

Overview

When adding custom TCP ports to a gateway definition (as documented here), helm upgrade fails with the following error:

✗ Helm upgrade failed: cannot patch "private" with kind Gateway: admission webhook "validation.istio.io" denied the request: configuration is invalid: server cannot have TLS settings for non HTTPS/TLS ports

Versions

• Bigbang: 2.5.0
• Istio: 1.17.3-bb.1
• K8s: v1.24.16-eks-2d98532

Context

We attempted to expose a custom TCP port on our Gateway with the following BB config snippet:

istio:
  gateways:
    public:
      hosts:
        - "{{ .Values.domain }}"
        - "*.{{ .Values.domain }}"
    private:
      hosts:
        - "*.{{ .Values.domain }}"
      ports:
        - name: https
          number: 8443
          protocol: HTTPS
        - name: tcp-custom
          number: 7687
          protocol: TCP

Viewing the bigbang/istio-bigbang-values secret shows the following (truncated) config:

gateways:
  private:
    servers:
    - hosts:
        - '*.bigbang.dev'
      port:
        name: https
        number: 8443
        protocol: HTTPS
      tls:
        mode: SIMPLE
        credentialName: private-cert
    - hosts:
        - '*.bigbang.dev'
      port:
        name: tcp-custom
        number: 7687
        protocol: TCP
      tls:
        mode: SIMPLE
        credentialName: private-cert

Reconciling the istio helm release results in the error shown above. It appears the tls section of the server host entry is added regardless of the port protocol resulting in the invalid configuration.

Temporary Workaround

As a stopgap solution, we were able to override the gateway's servers via istio.values:

istio:
  values:
    gateways:
      private:
        servers:
        - hosts:
            - '*.bigbang.dev'
          port:
            name: https
            number: 8443
            protocol: HTTPS
          tls:
            mode: SIMPLE
            credentialName: private-cert
        - hosts:
            - '*.bigbang.dev'
          port:
            name: tcp-custom
            number: 7687
            protocol: TCP
          # NOTE WE HAVE EXCLUDED THE TLS CONFIG FROM THIS HOST

It is also worth noting that when adding custom ports, 8443 or some other HTTPS port must also be included as shown above. Otherwise the helm upgrade fails similarly with:

Upgrade "istio-system-istio" failed: cannot patch "private" with kind Gateway: admission webhook "validation.istio.io" denied the request: configuration is invalid: server config must contain at least one host

Recommended Solutions

• Wrap the tls configuration block in a conditional based on port protocol
• Adjust the documented example to include (or explain the need for) the HTTPS port along with custom additions

Enable option to disable and enable istio injection for all charts

Description

The Istio injection is hardcoded as 'enabled' in this link: https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/templates/loki/namespace.yaml#L10. I've noticed this inconsistency across multiple charts. The recent Istio upgrade has disrupted logging and monitoring. I've identified that Istio injection is the root cause, but currently, there's no way to disable it.

Provide any steps possible used to reproduce the error (ideally in an isolated fashion).

After following the documentation located here, the default blobstores disappear. On our initial deployment of Nexus, the OSS version is deployed with blobstores attached. It seems when an external database is attached, a "factory reset" is done and the blobstores go away. Is it possible to keep the existing blobstores or do we have to recreate them entirely?

Initially we tried to go down the avenue of editing the helm chart, but according to this it is not recommended to do so.

Bug

Description

Minio-operator now deploys its own vs if enabled, but the vs gets bigbang.dev in the vs instead of the configured domain variable. The issue appears that the minio-operator template values is missing the domain declaration like the other services with exposed UIs has (like minio).

Quick workaround for now is just configuring the domain in the minio-operator values as well or just overriding the vs hosts altogether.

BigBang Version

2.21.1

The initial discovery of this problem resulted from trying to disable istio injection in gitlab-runner, but when digging in we found multiple discrepancies. When trying to set istio injection to disabled, we were confused by the fact that the default was already disabled as visible in the values, even though the running cluster had istio injection enabled:

istio:
  # Toggle istio integration
  enabled: false
  injection: disabled

Even after updating the values in our overrides, this didn't appear to change anything for istio injection in our cluster.

The actual helm code sets it to enabled by default. When trying to override with our own custom values, we similarly noticed that it would stay enabled. Istio settings are confusing because the templates are looking for them within the top level .Values.addons., and the defaults all get set to true because the fallback values are enabled. This adds to the confusion, because all of the settings per app in their respective values.yaml show istio is disabled and injection is disabled. The way these are templated is also inconsistent where some just use dig and others use a more comprehensive ternary.

Both of the following get set to enabled because the default values aren't set in the bigbang values.yaml

Anchore namespace.yaml in Big Bang code:
{{ ternary "enabled" "disabled" (and .Values.istio.enabled (eq (dig "istio" "injection" "enabled" .Values.addons.anchore) "enabled")) }}

and

Gitlab-runner namespace.yaml in Big Bang code:
{{ dig "istio" "injection" "enabled" .Values.addons.gitlabRunner }}

Both fallback to enabled because .Values.addons.<app>.istio isn't defined for any of the applications. The ternary also evaluates to true (enabled) because the dig falls back to "enabled" since the istio key doesn't exist under .Values.addons.anchore so we get "enabled" == "enabled" making eq true, and istio is enabled by default so the and evaluates to true.

Since the expected templating with the current defaults and values locations seems misleading and can be confusing to setup:

• the default values should be "enabled" for istio and injection to match the default configuration applied to these apps
• these values should either be moved under each app in the bigbang values.yaml or these checks for the values should be updated to use the one from app's values.yaml
• the method for getting values (using a ternary or just a dig) should be consistent for all of the apps

When using GitOps and configuring the istio.gateways.public.tls value incorrectly in secrets.enc.yaml the istio-ca-secret is created but not the public-cert secret. There are no logs that alert the users of the failed creation of the secret.
