@Rovel I ran into a similar issue and discovered the root cause. In the Dockerfile they specify the content/ path as a VOLUME mount point (https://github.com/docker-library/ghost/blob/master/2/alpine/Dockerfile#L59)

Removing this line fixes the issue (in my case, I just built my own image after forking)

Edit: forgot to note why this happens. Whenever a volume is declared in a Dockerfile, if any build step modifies the state of that path after the declaration occurs, then all of those changes are discarded (https://docs.docker.com/engine/reference/builder/#volume)

[Rovel]

So @spmurrayzzz does this works 100% since the content volume is not in the docker image, probably you will face some problems with saving configs, themes and stuff. did you?

An alternative is to run the container passing the volume path in the docker run after the image is built.

I had some doubts around the use of nginx and ssl config with ghost docker images the scripts that are built in to make this happen have no use in those docker issues, how did got around those too?

I did with AWS ALB and setting the ssl thru the ALB

[spmurrayzzz]

Our docker image/container is completely stateless. We run a dozen or so copies of ghost behind a load balancer, and all the content we store (imgs, etc) are synced to s3 via custom storage adapters (https://docs.ghost.org/concepts/storage-adapters/)

@spmurrayzzz Can you share your working dockerfile with s3 and entrypoint.sh, I am not able to get it working even after removing your mentioned line.

[spmurrayzzz]

@Rahulsharma0810 I should have used the commit hash url (the file has changed over time so line numbers no longer match up). But essentially would need to remove the VOLUME declaration in the Dockerfile if you plan to make changes to that particular path.

@spmurrayzzz is correct. I got the docker build working but once I deployed with environment variables the aws-sdk kicked back an error at me. Unfortunately it's very difficult to debug since the version for the aws-sdk is not pinned so it's unclear which version of the aws sdk I installed. I'd suggest to the author that they pin their versions especially for a library like this.
