# Docker

## Dependencies

- `git-crypt`

## Setup

Once DNS are properly setup on host:

1. Create OVH token : <https://www.ovh.com/auth/api/createToken>
    + `Get *`, `Put *`, ...
2. Paste token in `swag/dns-conf/ovh.ini`

### Services

## Create a new service

1. Add the service in `docker-compose.yml`
2. Create the DynHost <https://www.ovh.com/manager/#/web/domain/guiotte.fr/dynhost>
3. Add the host in the DDclient configuration `./ddclient/ddclient.conf`
4. Add the nginx proxy configuration in `./swag/nginx/proxy-confs/`
5. Update the local zone in `./bind9/guiotte.db`
6. Restart `bind9` and `swag`: `dcc restart bind9 swag`

## Update MariaDB

After upgrading from one major MySQL/MariaDB release to another, we have to run `mariadb-upgrade` on the services using MariaDB.

### Lychee

```bash
dcc stop lychee
dcc exec lychee-db mariadb-upgrade -u root -p"$(cat lychee-db-root-pw.secret)"
dcc restart lychee-db
dcc up -d lychee
```

### Nextcloud

```bash
dcc stop nextcloud
dcc exec nextcloud-db mariadb-upgrade -u root -p"$(cat nextcloud-db-root-pw.secret)"
dcc restart nextcloud-db
dcc up -d nextcloud
```

## Backup

To backup the named volumes, run:

```shell
./backup.py
```
