Installing docker

We recommend use of the Docker Community Edition: https://www.docker.com/community-edition.

Before installing CosmoSIS and the y3_cluster_cpp code, you must have Docker installed. Docker consists of a client and a daemon. For our installation of CosmoSIS to work, you must have the docker client installed, and the docker daemon installed and running. You must also be using a login that has permission to use docker; on Linux machines, this typically means you login must be a member of the docker group.

To see if you have the right permissions, you can try using the command docker version.

  • If you are told the docker command does not exist, then you do not have the docker client installed.
  • If the output shows you docker client version infromation, but tells you the docker daemon can not be contacted, either the daemon is not running or your login does not have permission to use docker.
  • If you get both client and daemon version information, you are ready to use docker.
