Share Docker socket via socat

In general this action is extremely insecure (you know what are you doing, right?)

export DEV_USER=jenkins
export DEV_UID=1000
export DEV_GID=1000

socat -d -d UNIX-LISTEN:/home/"${DEV_USER}"/.docker/docker_socket,fork,user="${DEV_UID}",group="${DEV_GID}",mode=777 UNIX-CONNECT:/var/run/docker.sock

export DOCKER_HOST=unix:///home/${DEV_USER}/.docker/docker_socket

Organize Git projects based on purpose

It is be possible to organize Git-cloned projects into folders based on work/personal criteria, for instance one folder could be completely dedicated to personal projects, while the other to work related projects.

We could have these two folders in our case:

  • ~/projects/personal/ - personal projects directory
  • ~/projects/work/ - work projects directory

Let's define configuration with sane defaults for git-cloned repositories outside of these two folders.

Run AWS metadata service locally


The idea is to run AWS metadata service on a local machine and redirect all link-local level requests to a mock server, which will provide real IAM credentials.
