Important

1. Below you will find instructions with example commands to run.
2. Commands to be run on your local machine will be marked with blue color.
3. Commands to be run on the Gateway will be marked with green color.
4. Commands to be run in the running container will be marked with red color.
5. The documentation covers usage of both Docker (running on your own computer) and uDocker (running on the Gateway). You do not have to follow both scenarios.

Installing container engine

• Docker on your own computer:

• uDocker on Gateway:

  Code Block
  language bash
  mkdir -p ~/.local/bin $ITMWORK/dot-udocker ln -s $ITMWORK/dot-udocker ~/.udocker curl https://raw.githubusercontent.com/indigo-dc/udocker/master/udocker.py > ~/.local/bin/udocker chmod u+rx ~/.local/bin/udocker echo "tmpdir='$ITMSCRATCH'" > ~/.udocker/udocker.conf ~/.local/bin/udocker install

Loading Docker image

• Docker on your own compujter:

  Code Block
  language bash
  scp login.eufus.eu:~g2tomz/public/imas-installer-20180921112143.tar.xz ./ xzcat imas-installer-20180921112143.tar.xz | docker load

• uDocker on Gateway:

  Code Block
  language bash
  xzcat ~g2tomz/public/imas-installer-20180921112143.tar.xz | ~/.local/bin/udocker load

...

• On the host machine, execute:

  Code Block
  language bash
  docker cp imas:/home/imas/public/imasdb/test/3/0/ids_10001.characteristics /tmp/ docker cp imas:/home/imas/public/imasdb/test/3/0/ids_10001.datafile /tmp/ docker cp imas:/home/imas/public/imasdb/test/3/0/ids_10001.tree /tmp/

• Check correctness of the results, on Gateway:

  Code Block
  language bash
  idsdump 1 1 equilibriumpf_active
