Dockerfile to build a tools image on CentOS 7

Tools image⁠ is intended to be used as Super Privileged Container⁠ (SPC) to extend the set of tools provided by Atomic Host. More tips how to use the image can be found at Project Atomic blog⁠.

To build, copy the sources down and call:

    # docker build --rm -t <username>/tools .

To run:

1. Not running on Atomic Host? Install the atomic tool with:

   # yum install atomic
   

   Copy

2. If you are at Atomic Host, you have atomic tool preinstalled and thus you can directly call

   # atomic run <username>/tools
   

   Copy

   to get a shell in the tools container, or

   # atomic run <username>/tools <command>
   

   Copy

   to run a specific command. For example:

   # atomic run <username>/tools man systemd
   

   Copy

atomic tool uses image labels to figure out the docker run command. You can check the RUN label⁠ by calling

docker inspect -f '{{.Config.Labels.RUN}}' <username>/tools
