I have a deployed Jenkins instance in Kubernetes.

In addition to that, the worker nodes are spawn as pods.

I am wondering if there is a possibility to run a docker inside the those pods (to run Testcontainers).

I was able to install docker inside ubuntu or alpine nodes, but I encountered a following problem:

# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I found that there is something like: Docker in Docker, where you can run something like this:

docker run -dit --restart=always -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock ltscustomjenkins

but it doesn’t sound helpful for my case.
