Cannot write output in Github action from Docker

[simonwfarrow]

Hi,

I am trying to execute your docker image in a Github workflow.

I see the following error :

Exception in thread "main" java.io.FileNotFoundException: docs/index.html (Permission denied)

I believe this is caused by setting the USER property in the Docker file :

USER generatr

As outlined here - https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#docker-container-filesystem

The full command the workflow runs is :

docker run -t --rm -v /runner/_work/electronic-architect/electronic-architect:/var/model ghcr.io/avisi-cloud/structurizr-site-generatr generate-site -w resources/ecom/dsl/ecom.dsl -o docs

And my workflow action is:

- name: Run docker image to create diagrams and markdown
        run: |
          docker run -t --rm -v ${{ github.workspace }}:/var/model ghcr.io/avisi-cloud/structurizr-site-generatr generate-site -w resources/ecom/dsl/ecom.dsl -o docs

if you add --user root to the docker command then it will run correctly with GitHub Actions. There is an example of the Github Action code that I'm using in the discussions section.
