Hello,

You would need to install Docker inside your Jenkins container. There are two ways to do that:

  • If your Jenkins container is already running, what you could do is attach to the container with the following command:
docker exec -it jenkins_container_id bash

Then while inside the container run the following commands:

apt-get update && apt-get install -y docker.io 
  • Another thing you could do is to share the Docker binary from your host so that it is accessible inside your Jenkins container, this is not great in terms of security:
docker run -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):$(which docker)  -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

Hope that this helps! Regards, Bobby
