Media Streaming Server with Rclone & Podman

This section covers the deployment of Navidrome music server, mounting cloud storage via Rclone FUSE, container permission fixes, and secure WAN routing using Cloudflare Tunnels.

1. Storage Integration: Rclone Google Drive FUSE Mount

To host a massive music library without filling up the local mini PC SSD, I integrated Google Drive.

The Challenge (Headless Authentication):

Rclone requires loggin in via a web browser (OAuth) to access Google Drive. Because media-stream VM is headless, I could not run a browser on it.

The Solution:

I ran the configuration wizard (rclone config) locally on the laptop to perform the web browser OAuth handshake.
I copied the generated access token file (rclone.conf) into the Ansible workspace.
I worte an Ansible playbook to copy the token file to /root/.config/rclone/rclone.conf on the VM.
I configured a custom Systemd Service (rclone-mount.service) to run:

/usr/bin/rclone mount gdrive: /mnt/gdrive/Music --allow-other --vfs-cache-mode full

--allow-other: Permits the Podman container's non-root user to read the host mount.
--vfs-cache-mode full: Buffers files locally on the SSD. Instead of a 10-second internet lag every time a song changes, the player pre-buffers the next track in the background, providing gapless playback.

2. Container Configuration & Troubleshooting Log

Issue #1: Navidrome Database Permissions Crash

The Issue: The Navidrome container crashed on boot with an error: Error applying PRAGMA optimize: unable to open database file.
The Discovery: The official Navidrome container runs as a secure non-root user with UID 1000. However, Ansible created the host directory /var/lib/navidrome as root:root. The container could not write its database files.
The Resolution: I modified the playbook to set the owner and group of /var/lib/navidrome to 1000:1000.

Issue #2: SELinux Blocking Container Volume Mounts

The Issue: The container ran, but could not see the music files.
The Discovery: SELinux was blocking the container process from reading the host /mnt/gdrive and /var/lib/navidrome directories.
The Resolution: I appended the :z flag to the Podman volume mount (/mnt/gdrive/Music:/music:ro,z). This tells Podman to automatically apply the correct SELinux security context label to the directories.

3. GitHub Push Protection Block

When I attempted to push my new configuration to GitHub, the push was declined with a an error: GH013 Repository rule violation: Push cannot contain secrets.

The Discovery:

I accidentally commited my plaintext rclone.conf token file in a previous local commit. GitHub's automated secret scanner detected the Google OAuth tokens and blocked the upload.

The Resolution (Rewriting Local History):

To remove the secret from the Git history completely before pushing, I ran:

# Soft reset to undo the commit but keep the files
git reset --soft HEAD~1

# Tell git to stop tracking rclone.conf
git rm --cached ansible/rclone.conf

# Add ansible/rclone.conf to .gitignore
# Recommit the clean files and push successfully
git add .
git commit -m " Complete deploying Navidrome on media-stream server as  a service"
git push -u origin main

4. WAN Routing: Secure Access via Cloudlfare Tunnels

To allow remote streaming (e.g., from Singapore) without opening security holes in my home router, I deployed a Cloudflare Tunnel.

sequenceDiagram
    autonumber
    actor Client as Phone / Client (Singapore)
    participant CF as Cloudflare Edge
    participant VM as media-stream VM (172.30.1.202)
    participant Nav as Navidrome Container

    VM->>CF: Outbound Tunnel connection established (cloudflared)
    Client->>CF: Access https://music.shooey.xyz
    CF->>CF: Verify SSL & security checks
    CF->>VM: Route traffic down the open tunnel
    VM->>Nav: Forward request to http://localhost:4533

Key Engineering Decisions:

Zero Inbound Ports: No port forwarding is configured on the home router. The VM opens an outbound-only connection (cloudflared), making the server completely invisible to public internet port scanners.
Ansible Automation (deploy_tunnel.yml): I wrote a playbook to install cloudflared via RPM and register the system service.
Ansible Idempotency (creates): Instead of using a separate stat check, I utilized the creates flag to ensure the registration command only runs if the service file doesn't exist:

- name: Install cloudflared systemd service
  ansible.builtin.command:
    cmd: "cloudflared service install {{ vault_cloudflare_token }}"
    creates: /etc/systemd/system/cloudflared.service

Cloudflare Published Application Routing: I configured Cloudflare to route the public subdomain music.shooey.xyz (HTTP) directoly to localhost:4533 via the tunnel.
