dind-options Docker Image
A slightly modified version of the official Docker-in-Docker
image (specifically the
docker:dind image), allowing arguments to its
entrypoint to be passed as an environment variable.
My main issue was that when using the official image as a Gitlab CI service, I
am unable to pass any CLI options. Because I use a Docker registry with a
self-signed certificate, I need to pass
--insecure-registry to dind during
As such, I added a small wrapper entrypoint that adds the contents of the
DOCKER_OPTS environment variable to the CLI arguments of the normal entrypoint.
This allows me to do this in Gitlab CI:
image: docker:latest variables: DOCKER_OPTS: "--insecure-registry=my.docker.registry" DOCKER_HOST: "tcp://lordgaav__dind-options:2375" services: - lordgaav/dind-options:latest
