Traefik Setup

My Traefik v3 configuration for homelab, without docker provider, only file-based templated dynamic configuration, static configuration and docker compose. My use case is a single domain and multiple subdomains, and this configuration generated a single wildcard certificate for all of them.

Here is the complete, professional deployment guide for the split-storage Immich architecture. This adheres strictly to the security principle of keeping the Proxmox host clean while isolating the database/thumbnails on the SSD and heavy media on the ZFS HDD array.

Phase 1: Proxmox Host Preparation (Storage & Security)

Run these commands directly on the Proxmox host shell.

1. Create a Dedicated Unprivileged User To prevent mapping the container to a privileged host user, create a "dead" user with no login access.

Since you are comfortable with the configuration and want a professional, proper systems administration approach, mitigating the security risk of idmap is straightforward.

The security risk exists only if you map the container to a privileged or shared host user (like your primary personal account, UID 1000, which might have sudo access or own sensitive host configurations). If a bad actor breaks out of the container via a Docker/LXC exploit, they land on the host with the permissions of that mapped UID.

To completely mitigate this risk, you create a "Black Hole" or "Empty Room" configuration. You punch a hole through the LXC isolation, but you make sure the hole leads to a user that has absolutely zero power on the host system.

Here are the exact methods to lock this down:

1. The "Dedicated Dead User" Strategy (Primary Mitigation)

Do not map the LXC container to UID 1000. Create a dedicated, unprivileged system account on the Proxmox host that exists solely to own this dataset.

As a Senior DevOps Engineer and Architect, I can tell you that you've hit one of the most common limitations of the GitLab CI YAML engine: GitLab does not natively support deep-merging dictionaries inside an array element (which is what workflow:rules is).

If you define a rule as a list item (e.g., - if: ...) and use !reference, GitLab treats that list item as a single block. You cannot easily inject or override variables inside it at the point of reference.

However, we can elegantly bypass this limitation by using what I call the "Nested Hash Extension" pattern.

Instead of defining your rules as an array in the common repo, we define them as a nested hash (dictionary). We then leverage GitLab's extends keyword (which does support deep-merging dictionaries, unlike arrays) to merge your custom variables in the child repository, and finally inject the resulting hash into workflow:rules using !reference.
