Looks like we found why whatever we tried resulted in our files being overwritten in the app during the rebuild process:
This is the reason seems to be because launcher pulls the base discourse image and that image has a.git directory and the git config file naturally points to the master discourse repo and then it overwrites our changes:
launcher
pull_image() {
# Add a single retry to work around dockerhub TLS errors
$docker_path pull $image || $docker_path pull $image
}
Before we mistakenly thought launcher built the image (how did we miss that?!) and it’s clear now that it pulls a base image from docker hub.
Back to the drawing board!
Is there a flag we can set which keeps launcher from pulling the base image and instead builds it?
