Outline

  • Create a docker container with a volume
  • Jump inside docker container and fuck with the volume
  • Backup volume
  • Delete volume
  • Restore container and volume

Create container with volume

docker volume create testvol
docker volume ls
docker volume inspect testvol
docker run -it \
    --name voltest \
    -v testvol:/testvol \
    ubuntu:latest
echo "I Like Pie" > /testvol/test.txt
cat /testvol/test.txt
# Should say "I Like Pie"
exit

Backup the docker volume to a tar file

docker stop voltest
mkdir ~/tmp-docker-backup 
docker run --rm --volumes-from voltest \
  -v ~/tmp-docker-backup:/backup ubuntu bash \
  -c "cd /testvol && tar cvf /backup/docker-vol-backup.tar ."

Remove the docker container and volume

docker rm -f voltest
docker volume rm testvol
docker ps -a
docker volume ls

Restore the docker volume and container

docker volume create testvol2
docker run --rm -v testvol2:/recover -v ~/tmp-docker-backup:/backup ubuntu bash -c "cd /recover && tar xvf /backup/docker-vol-backup.tar"
docker run -it \
  --name voltest2 \
  -v testvol2:/testbackup \
  ubuntu
ls /testbackup
cat  /testbackup/test.txt
exit
docker rm -f voltest2
docker volume rm testvol2
rm -r ~/tmp-docker-backup
