Docker

• To run docker inside docker (aware of related security issues) it’s necessary to use -v /var/run/docker.sock:/var/run/docker.sock and maybe sudo chmod +666 /var/run/docker. Also, the user inside the container must also belong to the docker user group (usermod -aG docker USER). This will be useful in dockerized environments used in CI/CD pipelines that deploy another dockerized application.
