Very simple question that I can’t find the answer to after several hours of searching. I need a docker compose update to target devices.

On my target devices the docker-compose.yml file is located here:  
/usr/local/app/dockerApp/docker-compose.yml

**How do create an artifact that updates this docker-compose.yml and its associated images?** Despite a few hrs of trying I’m unable to determine how to do this. I must imagine this is a common scenario.

Hi @grevelle,

Sounds like the Application Update Module should be a fit: [Tutorial: Docker Compose update | Mender documentation](https://docs.mender.io/artifact-creation/create-an-artifact/docker-compose)

Thanks @TheYoctoJester. I saw that as well. That tutorial doesn’t reference the location of the docker compose file. I am going to try changing both the docker compose file and the images using the docker compose update module and see what happens.

Hi @grevelle,

The `docker-compose.yml` in the example is this: [Tutorial: Docker Compose update | Mender documentation](https://docs.mender.io/artifact-creation/create-an-artifact/docker-compose#create-the-mender-artifact), see the file name created in the snippet.

In short, the workflow is like this:

1. you create the `docker-compose.yml` on the dev host.
2. the Application Update Module generation script bundles it together with all required container images into a Mender Artifact
3. the Artifact gets deployed
4. the Application Update Module on the device unpacks the container images and runs the `docker-compose.yml`

Greetz,

Thanks @TheYoctoJester! If I run into any issues I will share here.
