build image:

$ docker build -t fedora-workspace .

data volume usage:

$ docker create -d convoy --opt o=size5GB --name mydatavol
$ docker create -d convoy --opt o=size100MB --name mygcloudconfigvol
$ docker run -v mydatavol:/data -v mygcloudconfigvol:/home/luser/.config/gcloud [-v c:/Users/James/Docker/data/Gitlab/home/.ssh:/home/luser/.ssh] --name myworkspace -it ipv1337/fedora-workspace

data volume container usage:

$ docker create -v /data --name data-volume fedora /bin/true
$ docker create -v /home/luser/.config/gcloud --name gcloud-config-volume fedora /bin/true
$ docker run --volumes-from data-volume --volumes-from gcloud-config-volume [-v c:/Users/<username>/Docker/data/Gitlab/home/.ssh:/home/luser/.ssh] --name workspace -it ipv1337/fedora-workspace

backup volume:

$ docker run --rm --volumes-from data-volume -v $(pwd):/backup fedora tar cvf /backup/data-volume.tar /data
$ docker run --rm --volumes-from gcloud-config-volume -v $(pwd):/backup fedora tar cvf /backup/gcloud-config-volume.tar /home/luser/.config/gcloud

restore volume:

$ docker run --rm --volumes-from myworkspace -v C:/Users/James/Downloads:/backup fedora bash -c "cd /data && tar xvf /backup/data-volume.tar --strip 1"
$ docker run --rm --volumes-from myworkspace -v C:/Users/James/Downloads:/backup fedora bash -c "cd /home && tar xvf /backup/gcloud-config-volume.tar --strip 1"

find unused volumes:

$ docker volume ls -f dangling=true

using workspace:

$ docker-compose run workspace /bin/bash (creates a new container)
or
$ docker start workspace
$ docker attach workspace
$ kubectl exec -it workspace /bin/bash
