phpmyadmin service contains standalone phpMyAdmin interface that can be easily configured to access any MySQL server.

armada build phpmyadmin
armada run phpmyadmin

To configure custom list of MySQL servers, you can copy modified config/servers.php file to separate repository with configs.

If you use phpmyadmin-config repository and configure courier to deploy it on host with phpmyadmin, it will be automatically detected.

But you can also place the servers.php file anywhere on host, and add flag --configs [path_to_dir_with_servers.php] to armada run.

Additionally, if your MySQL servers can be accessed only via SSH, you can create ssh.json file with SSH tunnel definitions and put it in the same place as servers.php (described above).

The format of the ssh.json file is following:

[
    {
        "destination_host": "master.db.example.com",
        "destination_port": 3306,
        "local_port": 13306,
        "proxy_host": "ssh-proxy.example.com",
        "proxy_user": "tunnel",
        "proxy_port": 2200,
        "key": "tunnel@ssh-proxy.example.com.key"
    },
    ...
]

The file tunnel@ssh-proxy.example.com.key with private key for creating SSH tunnel should also be put in the same place as files servers.php and ssh.json.

Now, in servers.php you may use 127.0.0.1:13306 address to point to the above database. Do not use localhost instead of 127.0.0.1, because the phpmyadmin will try to use unix socket.
