Non-Alpine dind docker image - docker

Question

Is there an existing non-Alpine dind docker image?
Bind-mounting the host's docker socket does not work for me. I need proper dind. Docker's dind images seem to be all Alpine based, which also doesn't work for me.

Answer 1

Not exactly an answer to your question, but might solve your needs:
I assume that you don't really need non-Alpine, but rather GLIBC-enabled image.
I wanted an Docker-in-Docker capable image for Gitlab CI, which would have OpenJDK 12.
Such image is not yet available - AdoptOpenJDK images do not have DinD, and the official docker:* images can't install normal OpenJDK.
So I combined adoptopenjdk:12 with docker:stable, and it seems to work.
docker build --label docker-with-openjdk12 .

Answer 2

You just want to run Docker to perform CI System (build, run, push container images to hub) in Jenkins. Jenkins Master will launch Jenkins Slave as container and it will perform CI operation in it.
Yes you can run docker commands in inside jenkins slave container.
We required Docker binaries files in jenkins slave container, here while creating docker image through docker file we have added docker binaries file to it.
Once image build, we have just to volume mount Docker sock /var/run/docker.sock of host machine on container /var/run/docker.sock.
Here we are executing Docker-daemon from host machine and Docker client as jenkins slave container.
Please refer below GIT and Docker Hub repo:
