Add the secrets to Consul, near your service secrets.
The idea is that the backuping service is a component of the global running service.
You must add:
- `backup_aws_access_key_id`
- `backup_aws_secret_access_key`
- `backup_restic_repository`
- `backup_restic_password`
You must run in `app/<name>/secrets/<subpath>`:
```bash
echo "USER Backup AWS access key ID" > backup_aws_access_key_id
echo "USER Backup AWS secret access key" > backup_aws_secret_access_key
echo "USER Restic repository, eg. s3:https://s3.garage.tld" > backup_restic_repository
echo "USER Restic password to encrypt backups" > backup_restic_password
```
Then run secretmgr:
```bash
# Spawning a nix shell is an easy way to get all the dependencies you need
nix-shell
# Check that secretmgr works for you
python3 secretmgr.py check <name>
# Now interactively feed the secrets
python3 secretmgr.py gen <name>
```
