Push `.env` to Kubernetes

Buzz Guide reads private configuration from the buzz-sheet-env Kubernetes Secret in the buzz-sheet namespace. Use the local .env file as the source. Never commit .env or paste its values into a Kubernetes manifest.

This repository uses the manifests under k8s/, not a Kuber compose.yml, so environment-only updates are applied with kubectl.

1. Check the target cluster

Run these commands from the repository root:

kubectl config current-context
kubectl get namespace buzz-sheet

Stop if the context is not the cluster you intend to update.

Confirm that .env exists, then inspect only its variable names:

test -f .env
awk -F= '/^[A-Za-z_][A-Za-z0-9_]*=/{print $1}' .env

2. Create or update the Secret

The following command builds the Secret locally and sends it directly to the cluster. It does not create a plaintext YAML file:

kubectl create secret generic buzz-sheet-env \
  --namespace buzz-sheet \
  --from-env-file=.env \
  --dry-run=client \
  --output=yaml \
  | kubectl apply --filename=-

Verify that the Secret exists without displaying its values:

kubectl get secret buzz-sheet-env \
  --namespace buzz-sheet \
  --output='go-template={{range $key, $value := .data}}{{$key}}{{"\n"}}{{end}}'

Add DEPLOYMENT_WEBHOOK_SECRET to the Gitea Actions repository secrets with the same value stored in .env. CI uses it to announce deployment lifecycle updates to the running site.

3. Restart the application

Environment variables sourced from a Secret are read when a pod starts. Restart all Buzz Guide workloads after updating the Secret:

kubectl rollout restart deployment/buzz-sheet \
  --namespace buzz-sheet
kubectl rollout restart deployment/buzz-sheet-worker \
  --namespace buzz-sheet
kubectl rollout restart deployment/buzz-sheet-discord-worker \
  --namespace buzz-sheet

Wait for every rollout to finish:

kubectl rollout status deployment/buzz-sheet \
  --namespace buzz-sheet \
  --timeout=10m
kubectl rollout status deployment/buzz-sheet-worker \
  --namespace buzz-sheet \
  --timeout=10m
kubectl rollout status deployment/buzz-sheet-discord-worker \
  --namespace buzz-sheet \
  --timeout=10m

4. Verify the deployment

curl -fsS 'https://guide.sudloh.com/api/healthz'
bun logs

The health response should show "status":"ready" with both database and redis set to "ok".

Troubleshooting

namespace "buzz-sheet" not found: apply the base manifests first with kubectl apply --kustomize k8s/base.
Pods fail after the restart: inspect them with kubectl describe pod --namespace buzz-sheet <pod-name> and bun logs.
A new DATABASE_URL points to an empty database: run the database migrations before serving traffic. Updating the Secret does not migrate the database.
NEXT_DEPLOYMENT_ID comes from buzz-sheet-config, not .env.
Rotating NEXT_SERVER_ACTIONS_ENCRYPTION_KEY requires a new application build and deployment because Next.js uses it during the build.
S3_ENDPOINT must be the private S3-compatible API endpoint. S3_PUBLIC_URL must be the public read URL.
