Setelah install docker, setting user dan group-nya, tiba saatnya buat nge-test docker, walhasil permission denied ketik mau konek ke socket daemon-nya. Setelah cari-cari info, cuma butuh rubah permission file socket-nya saja.
Error Message
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/images/search?limit=25&term=centos": dial unix /var/run/docker.sock: connect: permission denied
