The Discourse Docker image fails on the following postgres.template.yml or XXX instruction: - exec: mkdir -p /shared/postgres_run.
The SELinux context doesn't allow the directory creation. I've also an issue with the lack of volumes in the story.
Docker has been restarted without SELinux support, as containers strong separation isn't an high priority on the Dwellers installation.
An enquiry should be made to the best way to improve the Discourse Docker images to comply with SELinux and use volumes.
