ssh command with docker dspace-dependencies image

[Stefan Fritzsche]

Dear community,

we are using the CI tools provided by our GitLab for our deploy workflow.

However, our workflow builds a docker container using the dspace/dspace-dependencies:dspace-7_x image. In this container it was possible to run the ssh command "before" (about 8 months ago). Unfortunately, this is no longer possible. Has the ssh command been removed from the image?

Regards,
Stefan

Hi Stefan,

We didn't purposefully remove SSH, but I do see that recently we switched the `dspace-dependencies` image to use `openjdk:11-slim` instead of previously using `tomcat:9-jdk11`.  The primary reason was to create a smaller image, as that image doesn't need to have all of Tomcat on it.

So, I'd recommend just adding SSH to your image if you need it.  Or, if you wish, you can provide a PR back to DSpace to suggest similar modifications to the Dockerfile for this image: https://github.com/DSpace/DSpace/blob/main/Dockerfile.dependencies

Hi Stefan,

 

As an aside, I’d be curious to hear how you’re using the Gitlab CI/CD tools with DSpace.

 

Are you using “dspace/dspace-dependencies:dspace-7_x” image for the Gitlab Runner container and then SSHing to your target Docker host server to do your Docker deployment?

Hello David

Sorry for my late reply.

You are correct, we are using the image to send the docker-compose commands to the Docker host via ssh. We have customized the Docker files to use our own images from the local Docker registry. The local Docker registry is also a part of our AI system.

The Gitlab pipeline has a stage that is responsible for building the image with the codebase from the last commit of the master branch and pushing the image to our Docker registry. By the way, it is important to use a Docker dind image if you want to run Docker commands inside a Docker container. In the next step, a container based on the dspace-dependencies image triggers the deploy via ssh.

I think we use the image because it is used by all other stages and it was possible to do ssh. In my opinion, we can also use another image in this stage. The reason to reduce the size of the dspace-dependencies image is more important.

With kind regards,
Stefan

Hi Stefan,

No worries. Thanks for the explanation. I think using a different image makes sense for that deployment stage too.
