# Workflow
Most applications in our Kubernetes cluster are managed by ArgoCD. Most applications in our Kubernetes cluster are managed by ArgoCD.
Most notably operators are NOT managed by ArgoCD. Most notably operators are NOT managed by ArgoCD.
Adding to `applications/`: `kubectl apply -f newapp.yaml` ## Managing applications
Update apps (see TODO below):
# Deployment
To deploy ArgoCD:
```bash
helm repo add argo-cd https://argoproj.github.io/argo-helm
kubectl create secret -n argocd generic argocd-secret # Initialize empty secret for sessions
helm template -n argocd --release-name k6 argo-cd/argo-cd --include-crds -f values.yaml > argocd.yml
kubectl apply -f argocd.yml -f application-extras.yml -f redis.yaml -f monitoring.yml -n argocd
kubectl label -n argocd secret oidc-client-argocd-owner-secrets app.kubernetes.io/part-of=argocd
kubectl -n argocd rollout restart deployment/k6-argocd-redis deployment/k6-argocd-repo-server deployment/k6-argocd-server deployment/k6-argocd-notifications-controller statefulset/k6-argocd-application-controller

# Setting up Git secrets
Generate SSH key to access Gitea:
```
ssh-keygen -t ecdsa -f id_ecdsa -C argocd.k-space.ee -P ''
kubectl -n argocd create secret generic gitea-kube \
--from-literal=type=git \
--from-literal=url=git@git.k-space.ee:k-space/kube \

kubectl label -n argocd secret gitea-members argocd.argoproj.io/secret-type=repository
rm -fv id_ecdsa
```
Have Gitea admin reset password for user `argocd` and log in with that account.
Add the SSH key for user `argocd` from file `id_ecdsa.pub`.
Delete any other SSH keys associated with Gitea user `argocd`.

### Repository secrets
1. Generate keys locally with `ssh-keygen -f argo`
2. Add `argo.pub` in `git.k-space.ee/<your>/<repo>` → Settings → Deploy keys
3. Add `argo` (private key) at https://argocd.k-space.ee/settings/repos along with referenced repo.
## Argo Deployment
To deploy ArgoCD itself:
```bash
helm repo add argo-cd https://argoproj.github.io/argo-helm
kubectl create secret -n argocd generic argocd-secret # Empty secret for sessions
helm template -n argocd --release-name k6 argo-cd/argo-cd --include-crds -f values.yaml > argocd.yml
