# Container

Use `podman` or `docker`:

```sh
podman run code.philo.ydns.eu/philorg/sms-handler
```

Parameters are given as environment variables, eg.:

```sh
podman run -e SMS_HANDLER_MAIL_SERVER_PORT=8025 -e SMS_HANDLER_MAIL_SENDER=snoopy@peanuts.com SMS_HANDLER_MAIL_TO=snoopy@peanuts.com code.philo.ydns.eu/philorg/sms-handler
```

## Container as a systemd service

Systemd can "orchestrate" containers easily thanks to podman.

### Rootless (as regular user)

For a rootless container, create a file in `.config/containers/systemd/sms-handler.container`.
The configuration is given as environment variables (email addresses `snoopy@peanuts.com` in this example):

```systemd
[Container]
ContainerName=sms-handler
Environment=SMS_HANDLER_MAIL_SENDER=snoopy@peanuts.com
Environment=SMS_HANDLER_MAIL_TO=snoopy@peanuts.com
Image=code.philo.ydns.eu/philorg/sms-handler
Network=podman
PublishPort=8025:8025

[Service]
Restart=always

[Install]
WantedBy=default.target
```

Request systemd to reload configuration, creating the service for this container:

```sh
systemctl --user daemon-reload
```

Start the container as a service:

```sh
systemctl start sms-handler.service
```

To start rootless containers at boot time, without the need for the user (snoopy) to log in:

```sh
sudo loginctl enable-linger snoopy
```

### Rootful (as root)

For a rootless container, create a file in `/etc/containers/systemd/sms-handler.container`:

```systemd
[Container]
ContainerName=sms-handler
Environment=SMS_HANDLER_MAIL_SENDER=snoopy@peanuts.com
Environment=SMS_HANDLER_MAIL_TO=snoopy@peanuts.com
Image=code.philo.ydns.eu/philorg/sms-handler
Network=podman
PublishPort=8025:8025

[Service]
Restart=always

[Install]
WantedBy=default.target
```

Request systemd to reload configuration, creating the service for this container:

```sh
sudo systemctl daemon-reload
```

Start the container as a service:

```sh
sudo systemctl start sms-handler.service
```
