General information for what on CloudLab profiles created via GitHub repo can be found in the example repo here or in the CloudLab manual

Specifically, the goal of this repo is to create a CloudLab profile that allows for one-click creation of a Kubernetes OpenWhisk deployment for academic research.

Create a CloudLab experiment using the OpenWhisk profile. It's recommended to use at least 3 nodes for the cluster. It has been testsed on m510, xl170, and rs630 nodes (e.g., various Intel architectures, not ARM, so do not choose an ARM node).

On each node, a copy of this repo is available at:

    /local/repository

Installation specific material (which is baked into the CloudLab disk image) is found at:

    /home/cloudlab-openwhisk

Docker images are store in additional ephemeral cloudlab storage, mounted on each node at:

    /mydata

To see information on OpenWhisk pods, make sure to specify the namespace as openwhisk. To remove OpenWhisk, run the following commands:

    $ cd /home/cloudlab-openwhisk/openwhisk-deploy-kube
    $ helm uninstall owdev -n openwhisk
    $ kubectl delete namespace openwhisk

To start OpenWhisk again, run:

    $ kubectl create namespace openwhisk
    $ cd /home/cloudlab-openwhisk/openwhisk-deploy-kube
    $ helm install owdev ./helm/openwhisk -n openwhisk -f mycluster.yaml

The configuration of OpenWhisk deployed by the experiment is found at: /home/cloudlab-openwhisk/openwhisk-deploy-kube/mycluster.yaml, and is identical to the one found here, except populated with the IP of the primary node. The default OpenWhisk created by this profile is not optimized in any way.

To upgrade OpenWhisk, such as after modifying the mycluster.yaml file, run the following helm command:

    $ helm upgrade owdev ./helm/openwhisk -n openwhisk -f mycluster.yaml

If anything went wrong with the profile, check the log found at on all nodes:

    $ /home/cloudlab-openwhisk/start.log

Version 3 of this profile is found in the v3 branch (and main).

• Can toggle deployment of the new scheduler
• Moved openwhisk options from advanced to regular
• Updated software in image

Version 2 of this profile is found in the v2 branch.

• Includes bug fixed from version 1 regarding extra storage in /mydata
• Fixes permissions in /home/ directories
• Removes need to run start script after first login to populate environment variables
• Includes fixes from npm dependency error

Version 1 of this profile is found in the v1 branch.

The image_setup.sh script is how the image was created from the base CloudLab Ubuntu 20.04 image.
