Cluster deployment

Cluster setup

As as example, we will use K3s. K3s is setup with the following command (see the k3s documentation):

> curl -sfL https://get.k3s.io | sh -

For windows users, The howtos section tells how to quickly install k3s on Windows.

Pre-requisites

From where you deploy autocloud, you will need:

  • The credentials (SSH key) to access the git repository.
  • The age key used to encrypt the secrets.

You also need the following software:

  • git
  • kustomize
  • kubectl
  • krmfnbuiltin

If you're deploying from the machine on which you performed the environment customization you should be good to go.

Deployment

Because this is GitOps, the bootstrapping is done by deploying what has been pushed:

$ kustomize build --enable-alpha-plugins --enable-exec \
> "git@github.com:klasmik/klasmikloud.git//packages/argocd/?ref=deploy/devenv" \
> | kubectl apply -f

PS> kustomize build --enable-alpha-plugins --enable-exec \
> "git@github.com:klasmik/klasmikloud.git//packages/argocd/?ref=deploy/devenv" \
> | kubectl apply '-f'

Checking deployment status

You can check the deployment status with the following command:

>  kubectl -n argocd rollout status deployments,statefulsets,daemonsets --timeout=90s
deployment "argocd-redis" successfully rolled out
deployment "argocd-applicationset-controller" successfully rolled out
deployment "argocd-dex-server" successfully rolled out
deployment "argocd-notifications-controller" successfully rolled out
deployment "argocd-repo-server" successfully rolled out
deployment "argocd-server" successfully rolled out
partitioned roll out complete: 1 new pods have been updated...
>

And then see the applications with the following command:

> kubectl -n argocd get applications
NAME                      SYNC STATUS   HEALTH STATUS
appstage-00-bootstrap     Synced        Healthy

argo-cd                   Synced        Healthy
