running docker on windows

[katilp]

• Download Docker toolbox (if no Windows 10 Pro) https://docs.docker.com/toolbox/overview/
• Open Docker Quickstart Terminal
• Follow the instructions in https://docs.docker.com/docker-for-windows/
• Try CMSSW containers from https://hub.docker.com/r/cmssw/cmssw/tags/ with docker pull cmssw/cmssw:CMSSW_7_3_0

This works, another option without installing toolbox below

Install with: https://golb.hplar.ch/2019/01/docker-on-windows10-home-scratch.html

then on command prompt

start_docker 
docker-machine ssh

docker run .... (see http://opendata.cern.ch/docs/cms-guide-docker and https://github.com/clelange/cmssw-docker/) e.g.

docker run --name opendata -it cmsopendata/cmssw_5_3_32 /bin/bash (without cvmfs access) or

docker run --rm --privileged -it clelange/slc6-cmssw-cvmfs /bin/bash (with cvmfs access)

docker ps (lists running containers) docker images (lists downloaded images) docker --help

Question(s):

• is it possible to open another terminal in the same container? (no xterm or gnome-terminal available)

The cmssw-cvmfs container reads the condition data in cache if that container is kept (run without -rm) and used another time. The cache usage (df) shows the same when the container is started again, but the starting time for the test job still slow😕 and apparently the condition data is not read from cache but from the cvmfs (TBC)

Just for completeness

• docker images shows downloaded images e.g.
• docker ps -a shows all containers ( the default without -a only the running containers), e.g.

VirtualBox GUI does not need to be running.
