k8s-ocis

A collection of kubectl yaml files to deploy ocis onto kubernetes. Customisation is provided via kustomize. Official helm still beta.

Requirements

• Kustomize
• Kubernetes Cluster (I'd recommend RKE2 from Rancher)

These are not necessary but useful if you want to store your data outside the cluster.

• TrueNAS
• Democratic-csi (For auto creating NFS/ISCSI shares on TrueNAS)

Kustomize

Pretty simple to install. It does come with kubectl but if you want the latest one you can use docker.

docker pull k8s.gcr.io/kustomize/kustomize:v3.8.7

Then running a command via it:

docker run k8s.gcr.io/kustomize/kustomize:v3.8.7 version

Install/Deployment

Copy the example overlays folder so you can customise to your liking. I have provided examples of changing the most common things, but you can change most parts via kustomize.

Example Values:

OCIS_OIDC_ISSUER:

https://keycloak_url/realms/home

Via kubectl

Build the templates to see what they look like without applying.

kubectl kustomize overlays/custom

Deploy to the cluster.

kubectl apply -k overlays/custom

Via docker kustomize

Build the templates to see what they look like without applying.

docker run -v absolute_path_to_checkout:/k8s k8s.gcr.io/kustomize/kustomize:v3.8.7 build /k8s/overlays/custom

Deploy to the cluster.

docker run -v absolute_path_to_checkout:/k8s k8s.gcr.io/kustomize/kustomize:v3.8.7 build /k8s/overlays/custom | kubectl apply -f -
