## Production
**PeerTube does not support webserver host change**. Keep in mind your domain
name is definitive after your first PeerTube start.
-#### Go to your peertube workdir

+_note_: the guide that follows assumes an empty workdir, but you can also clone the repository, use the master branch and `cd support/docker/production`.
```shell
cd /your/peertube/directory
$EDITOR ./docker-compose.yml
```
-#### Then tweak the `.env` file to change the environment variables

Now that you've installed your PeerTube instance you'll want to grep your peertube container's logs for the `root` password. You're going to want to run `docker-compose logs peertube | grep -A1 root` to search the log output for your new PeerTube's instance admin credentials which will look something like this.
```bash
-user@s:~/peertube|master⚡ ⇒ docker-compose logs peertube | grep -A1 root
+$ docker-compose logs peertube | grep -A1 root
peertube_1 | [example.com:443] 2019-11-16 04:26:06.082 info: Username: root
peertube_1 | [example.com:443] 2019-11-16 04:26:06.083 info: User password: abcdefghijklmnop
Run `cat ./docker-volume/opendkim/keys/*/*.txt` to display your DKIM DNS TXT Record containing the public key to configure to your domain :
```bash
-user@s:~/peertube|master⚡ ⇒ cat ./docker-volume/opendkim/keys/*/*.txt
+$ cat ./docker-volume/opendkim/keys/*/*.txt
peertube._domainkey.mydomain.tld. IN TXT ( "v=DKIM1; h=sha256; k=rsa; "
