Adding your own containers in YAMS is very easy.

First, go to your install location. For the purposes of this tutorial, I’ll use /opt/yams.

cd /opt/yams

If you ls, you’ll see 2 files:

• docker-compose.yaml: This is YAMS. You shouldn’t mess with this file manually.
• docker-compose.custom.yaml: Here’s where you’ll add your containers. Any container you add here will be automatically added to the YAMS network and will be able to communicate locally with YAMS.

To add your containers, you’ll have a few environment variables available:

• PUID: Your PUID.
• PGID: Your PGID.
• MEDIA_DIRECTORY: Your media directory.
• INSTALL_DIRECTORY: Your install location.

Adding a container

As an example, I’ll add Overseerr.

Open docker-compose.custom.yaml and add the following information:

version: "3"

services: # -> Uncomment this line! (remove the "#" in front of it)

# Add your container here 👇 
  overseerr:
    image: lscr.io/linuxserver/overseerr:latest
    container_name: overseerr
    environment:
      - PUID=${PUID} # Note how I'm using the env variables here
      - PGID=${PGID} # Note how I'm using the env variables here
    volumes:
      - ${INSTALL_DIRECTORY}/config/overseer:/config # Note how I'm using the env variables here
    ports:
      - 5055:5055
    restart: unless-stopped

To start the container, run:

yams restart

If everything is okay, you should see Overseer installing:

 ⠙ overseerr Pulling                                                                            5.2s


 ...

And that’s it!
