Using cats-admin service account ¶

The cats-admin service account provides access to the production application and database to run commands, open shells, view logs, and forward ports.

Download the indevets-cats-admin.yaml attachment from the cats-admin @ indevets k8s secret in BitWarden into your ~/.kube directory
Activate the downloaded KUBECONFIG in your current terminal session:
```
export KUBECONFIG=~/.kube/indevets-cats-admin.yaml
```

Switch to indevets-production namespace:

kubectl config set-context --current --namespace=indevets-production

Get the name of the currently running production pod and container name prefix and store them as shell variables:

APP_POD=$(kubectl get pod -l app.kubernetes.io/name=indevets-core -o jsonpath='{.items[0].metadata.name}')
CONTAINER_PREFIX=indevets-core-prod

Open interactive app shell ¶

kubectl exec -it $APP_POD -c ${CONTAINER_PREFIX}-app -- bash

Check version ¶

kubectl exec $APP_POD -c ${CONTAINER_PREFIX}-app -- bash -c 'echo $SOURCE_TAG'

Open interactive database shell ¶

kubectl exec -it $APP_POD -c ${CONTAINER_PREFIX}-db -- bash -c 'psql -U${POSTGRES_USER}'

Run an artisan command ¶

kubectl exec -it $APP_POD -c ${CONTAINER_PREFIX}-app -- artisan migrate

Run an SQL query ¶

echo 'SELECT * FROM users' | kubectl exec -i $APP_POD -c ${CONTAINER_PREFIX}-db -- bash -c 'psql -U${POSTGRES_USER}'

Forward PostgreSQL port ¶
