Note: The first migration file was taken when the DB was at git revision 8acb5f22. If you already have a database you should ensure your database container schema matches 8acb5f22 and then update to b99fdbc8, build images, update containers and run ./flask-cli.sh db stamp head to tell flask-migrate that your database is starting from that state.

./flask-cli.sh db upgrade to apply new migrations to your database container (after updating the containers)

./app-cli.sh seed_db seed the database with roles and permissions (once the initial migration is applied to the database you should do this)

./app-cli.sh add_user <EMAIL> <PASSWORD create a new user

./app-cli.sh add_role <EMAIL> <ROLE grant a role to a user

We use the --wallet flag (https://lightning.readthedocs.io/BACKUP.html#sqlite3-wallet-main-backup-and-remote-nfs-mount) in order to make a replica of the database. We can use sshfs to make the replica offsite.

• add LIGHTNINGD_REPLICA=1 to the .env file
• add the beryllium server ssh pubkey to the backup server authorized ssh keys (~/.ssh/authorized_keys)
• install sshfs on the beryllium server (apt install sshfs)

First setup the mount:

BE_SERVER_NAME=`hostname --fqdn`
LOCAL_REPLICA_DIR=`realpath lightningd/replica/`
# this needs to be an absolute directory
REMOTE_REPLICA_DIR={remote_user_home_dir}/$BE_SERVER_NAME
ssh {remote_user}@{backup_server} mkdir $REMOTE_REPLICA_DIR
sshfs -o allow_other,default_permissions {remote_user}@{backup_server}:$REMOTE_REPLICA_DIR $LOCAL_REPLICA_DIR

Now restart the lightning container:

docker stop lightningd
docker compose up -d

Now check the replica exists locally and remote and have the same size and modified date:

# local
ls -l lightningd/replica/lightningd.sqlite3
# remote
ssh {remote_user}@{backup_server} ls -l $REMOTE_REPLICA_DIR/lightnind.sqlite3

Add the following to /etc/fstab:

{remote_user}@{backup_server}:{remote_replica_dir} {local_replica_dir} fuse.sshfs noauto,x-systemd.automount,_netdev,reconnect,identityfile=/{user_home_dir}/.ssh/id_rsa,allow_other,default_permissions 0 0

You can test the permenent mount by rebooting
