I'm in a project where we're going to need several vms with ignition, and I'm using Docker to create the containers.

In the documentation I saw how to add the desired modules. Would it be possible to add third party modules in docker-compose.yaml?

Or would it be necessary to create an image with these modules?

There are a couple of ways to go about this. The simplest way, if you're using Docker Compose, is to just have a folder (say `modules`) with the third-party modules you'd like to add. Then, simply bind-mount _the individual modules_ into place under `/usr/local/bin/user-lib/modules`. It might look something like this:

```auto
services:
  gateway1:
    ...
    volumes:
      - gateway1-data:/usr/local/bin/ignition/data
      - ./modules/MQTT-Engine-signed.modl:/usr/local/bin/ignition/user-lib/modules/MQTT-Engine.modl
    ...

```

Then, when you launch the services, they'll load that module alongside the others that are in that folder (from the base image). Combine this with the `GATEWAY_MODULES_ENABLED` environment variable to whitelist the other built-in modules as desired.

do we need to also create the ./modules folder in the ignition folder along with the usr/local/bin?

In the example above, `modules` is a folder on the host system (relative to where the `docker-compose.yml` file is located) where you're keeping the third-party modules you're then linking into the container.

Hi @Kevin.Collins I put my modules in

```python
/usr/local/bin/ignition/user-lib/modules/MQTT-Engine.modl

```

I wasn't sure what the left of the colon needs to represent

Sounds like reviewing [Bind-mounts](https://docs.docker.com/engine/storage/bind-mounts/) might be useful. Also of use might be the [`volumes`](https://github.com/compose-spec/compose-spec/blob/6632cc1064e1d5461e59cd80db8096367fc78840/05-services.md#volumes) section of the Compose spec.
