0.8.4

Docker Image

If you have been running a node using the v0.8.3 Docker image, the node was not saving data to the
specified data directory,
or referring to the custom configuration file
or genesis file.

To recover the node key and data directory from the Docker container:
docker cp <container>:/opt/pantheon/key <destination_file>
docker cp <container>:/opt/pantheon/database <destination_directory>

Where container is the name or ID of the Docker container containing the Pantheon node.

The container can be running or stopped when you copy the key and data directory. If your node was
fully synchronized to MainNet, the data directory will be ~2TB.

When restarting your node with the v0.8.4 Docker image:

• Save the node key in the key file in the data
  directory or specify the location using the --node-private-key option.
• Specify the <destination_directory as a volume for the data directory.
