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.

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:

kubectl create secret generic s3-credentials \
    --from-literal=username="$exoscale_iam_key" \
    --from-literal=password="$exoscale_iam_secret" \
    -n $namespace
