Slave image does not support running docker

Question

I'm using the Kubernetes Jenkins plugin to arrange jenkins slaves

I want to run all the jobs in Docker

I am using the jenkinsci/jnlp-slave from here:

https://hub.docker.com/r/jenkinsci/jnlp-slave/

the slave image doesn't appear to support running docker. How do I fix this?

Answer 1

You need to install docker client and mount the docker socket so you can access the Docker host. Then you can interact with that Docker host

Also set the container name a jnlp so that it does not creates another container inside the pot.
