To deploy on minikube using helm follow the steps in start-minikube-and-deploy.sh or just run the script from the root folder of the project.

chmod +x start-minikube-and-deploy.sh
./start-minikube-and-deploy.sh

This script will

• Delete existing minkube cluster if present
• Start a new minikube cluster with calico container network interface
• Build the docker images and load into minikube cluster registry
• Enable and configure ingress addon for TLS
• Lint and install helm charts
• Check the state of the pods after deploying

curl https://$(minikube ip) -k
curl https://$(minikube ip)/api/number -k
curl https://$(minikube ip)/api/number -k -X POST

https:// enforces TLS port 443 and -k ignores self-signed issue.

1. cd to containerization/helm
2. Lint the helm chart helm lint
3. Make sure docker images for api/ and front/ are built.
4. Push docker images for api and front again to minikube (see deploy.sh).
5. Install helm chart (on empty cluster!) helm install containerization .
6. Upgrade deployment with helm upgrade containerization .
7. Rollback to previous version with helm rollback containerization <optional revision num>
8. Uninstall chart with helm uninstall containerization

Generate private key, certificate signing request and self-signed certificate.

openssl req -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr
openssl x509 -signkey domain.key -in domain.csr -req -days 365 -out domain.crt

Create secret

kubectl create secret tls tls-certificate --key domain.key --cert domain.crt
