Docker Volumes

Docker Volumes (Persistent Paths)

The following paths will be shared between the Host (ec2-linux or macosx-laptop) and the Docker Container:

[MacOS X Only] boot2docker Persistent Path

/var/lib/boot2docker

Docker Persistent Path

/var/lib/docker

Notes:

• The -v ~/pipeline/notebooks maps persistent path inside the Docker Container. This way, you won't lose changes to your Apache Zeppelin or Spark-Notebook notebooks while running inside Docker.
• Consider everything - both in-memory or on-disk - inside the Docker Container to be scoped to the life of just that Container.
• If the Docker Container crashes or you exit the bash session, you will lose data if you're not using VOLUMES (-v)!
• If you're other assets that you want to persist, make sure to commit/push them to git or save them outside of the ephemeral Docker Container - otherwise they may disappear.
• Be careful with mapping local paths that are under git's control. Things get wonky sometimes. (hand-waving)
