# Octopus Server Container with systemd

You can use `systemd` to boot the Octopus Server Linux container each time the OS starts. To do this, create a file called `/etc/systemd/system/docker-octopusdeploy.service` with the following contents:

:::div{.hint}
Be sure to change the `ADMIN_PASSWORD` and `MASTER_KEY` from the defaults shown here.

```

Note that we assume a Docker bridge network called `octopus` exists. This can be created with the command:

```bash
docker network create -d bridge octopus
```

The Octopus service also relies on a MS SQL service define in the file `/etc/systemd/system/docker-mssql.service` with the following contents:

```
[Unit]
Description=Daemon for mssql
After=docker.service
Wants=
Requires=docker.service
StartLimitIntervalSec=20
StartLimitBurst=3

[Service]
Restart=on-failure
TimeoutStartSec=0
RestartSec=5
Environment="HOME=/root"
SyslogIdentifier=docker-mssql
ExecStartPre=-/usr/bin/docker create --net octopus -m 0b -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password01!" -e "MSSQL_PID=Express" -e "MSSQL_MEMORY_LIMIT_MB=2048" -p 1433:1433 --restart=always --name mssql mcr.microsoft.com/mssql/server:2019-latest
ExecStart=/usr/bin/docker start -a mssql
ExecStop=-/usr/bin/docker stop --time=0 mssql

[Install]
WantedBy=multi-user.target
```

To load the new service files, run:

```bash
systemctl daemon-reload
```

Then start the services with the commands:

```bash
systemctl start docker-mssql
systemctl start docker-octopusdeploy
```
