Mint System Nextcloud

This Helm chart deploys Nextcloud with PostgreSQL.

Secrets

Setup a nextcloud-creds secret with any additional environment variables you want to pass to Nextcloud.

NEXTCLOUD_ADMIN_USER="admin"
NEXTCLOUD_ADMIN_PASSWORD="*******"
kubectl create secret generic nextcloud-creds \
    --from-literal=NEXTCLOUD_ADMIN_USER="$NEXTCLOUD_ADMIN_USER" \
    --from-literal=NEXTCLOUD_ADMIN_PASSWORD="$NEXTCLOUD_ADMIN_PASSWORD" \
    -n <namespace>

The K8up backup requires a s3-credentials and a backup-repo secret. Here is an example for Exoscale SOS:

EXOSCALE_IAM_KEY="*******"
EXOSCALE_IAM_SECRET="*******"
kubectl create secret generic s3-credentials \
    --from-literal=username="$EXOSCALE_IAM_KEY" \
    --from-literal=password="$EXOSCALE_IAM_SECRET" \
    -n <namespace>
