Prerequisite services

These manifests create the PostgreSQL, Redis and RabbitMQ instances that the Euro-Office and Nextcloud charts expect. They are applied manually before Argo CD syncs the application charts; they are not part of the Argo CD root Application (which only watches apps/).

See ../../../installation-steps.md for the full installation record, including the NFS provisioner and the Argo CD Applications.

Usage

Create the namespaces and the NFS provisioner as described in installation-steps.md sections 2 and 3.

Create credentials.env next to this README (never commit it):

umask 077
{
  echo "POSTGRES_PASSWORD=$(openssl rand -hex 16)"
  echo "EUROOFFICE_DB_PASSWORD=$(openssl rand -hex 16)"
  echo "NEXTCLOUD_DB_PASSWORD=$(openssl rand -hex 16)"
  echo "REDIS_PASSWORD=$(openssl rand -hex 16)"
  echo "RABBITMQ_PASSWORD=$(openssl rand -hex 16)"
  echo "JWT_SECRET=$(openssl rand -hex 32)"
  echo "NEXTCLOUD_ADMIN_PASSWORD=$(openssl rand -hex 16)"
} > credentials.env

Apply the secrets and services:
```
bash setup-prereqs.sh
```

setup-prereqs.sh creates the Kubernetes Secrets, applies the three manifests, and waits for the Deployments. It expects credentials.env in the current directory.

Notes

PostgreSQL creates both the eurooffice and nextcloud databases and roles on first start.
The Redis Service is named redis-master because that is the name the Euro-Office chart expects.
RabbitMQ’s readiness probe uses timeoutSeconds: 15; the default 1 second is too short for rabbitmq-diagnostics -q ping.
