    Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.25/images/json: dial unix /var/run/docker.sock: connect: permission denied

    Would appreciate your assistance

  • Installing a web application in a Docker container: dial unix /var/run/docker.sock: no such file or directory
  • Set Docker_Opts in centos
  • Cannot connect to remote docker host via SSH forwarded domain socket
  • Is it possible to use cloud-init and heat-cfntools inside a Docker container?
  • Unable to see the contents in the docker container
