SSH_HOST_KEY="hostname ssh-rsa AAAAB3...
COMPOSE_FILE="$COMPOSE_FILE:compose.ssh.yml"
```
To get the `SSH_HOST_KEY` run the following command `ssh-keyscan <hostname>`
Generate an ssh keypair: `ssh-keygen -t ed25519 -f backupkey -P ''`
and add your `SSH_KEY` as docker secret:
`abra app secret insert <app_name> ssh_key v1 "$(cat backupkey)"`
Add the key to your `authorized_keys`:
`ssh-copy-id -i backupkey <user>@<hostname>`
Add your `SSH_KEY` as docker secret:
```
abra app secret insert <app_name> ssh_key v1 """$(cat backupkey)
"""
```
