   1 # Docker guide
   2
   3 This guide requires [docker](https://www.docker.com/community-edition) and
   4 [docker-compose](https://docs.docker.com/compose/install/).
   5
   6 ## Install
   7
   8 **PeerTube does not support webserver host change**. Keep in mind your domain
   9 name is definitive after your first PeerTube start.
  10
  11 #### Go to your workdir
  12
  13 _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`.
  14
  15 ```shell
  16 cd /your/peertube/directory
  17 ```
  18
  19 #### Get the latest Compose file
  20
  21 ```shell
  22 curl https://raw.githubusercontent.com/chocobozzz/PeerTube/master/support/docker/production/docker-compose.yml > docker-compose.yml
  23 ```
  24
  25 View the source of the file you're about to download: [docker-compose.yml](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/docker-compose.yml)
  26
  27 #### Get the latest env_file
  28
  29 ```shell
  30 curl https://raw.githubusercontent.com/Chocobozzz/PeerTube/master/support/docker/production/.env > .env
  31 ```
  32
  33 View the source of the file you're about to download: [.env](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/.env)
  34
  35 #### Tweak the `docker-compose.yml` file there according to your needs
  36
  37 ```shell
  38 $EDITOR ./docker-compose.yml
  39 ```
  40
  41 #### Then tweak the `.env` file to change the environment variables settings
  42
  43 ```shell
  44 $EDITOR ./.env
  45 ```
  46
  47 In the downloaded example [.env](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/.env), you must replace:
  48 - `<MY POSTGRES USERNAME>`
  49 - `<MY POSTGRES PASSWORD>`
  50 - `<MY DOMAIN>` without 'https://'
  51 - `<MY EMAIL ADDRESS>`
  52 - `<MY PEERTUBE SECRET>`
  53
  54 Other environment variables are used in
  55 [/support/docker/production/config/custom-environment-variables.yaml](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/config/custom-environment-variables.yaml) and can be
  56 intuited from usage.
  57
  58 #### Webserver
  59
  60 *The docker compose file includes a configured web server. You can skip this part and comment the appropriate section in the docker compose if you use another webserver/proxy.*
  61
  62 Install the template that the nginx container will use.
  63 The container will generate the configuration by replacing `${WEBSERVER_HOST}` and `${PEERTUBE_HOST}` using your docker compose env file.
  64
  65 ```shell
  66 mkdir -p docker-volume/nginx
  67 curl https://raw.githubusercontent.com/Chocobozzz/PeerTube/master/support/nginx/peertube > docker-volume/nginx/peertube
  68 ```
  69
  70 You need to manually generate the first SSL/TLS certificate using Let's Encrypt:
  71
  72 ```shell
  73 mkdir -p docker-volume/certbot
  74 docker run -it --rm --name certbot -p 80:80 -v "$(pwd)/docker-volume/certbot/conf:/etc/letsencrypt" certbot/certbot certonly --standalone
  75 ```
  76
  77 A dedicated container in the docker-compose will automatically renew this certificate and reload nginx.
  78
  79
  80 #### Test your setup
  81
  82 Run your containers:
  83
  84 ```shell
  85 docker-compose up
  86 ```
  87
  88 #### Obtaining your automatically-generated admin credentials
  89
  90 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.
  91
  92 ```bash
  93 $ docker-compose logs peertube | grep -A1 root
  94
  95 peertube_1  | [example.com:443] 2019-11-16 04:26:06.082 info: Username: root
  96 peertube_1  | [example.com:443] 2019-11-16 04:26:06.083 info: User password: abcdefghijklmnop
  97 ```
  98
  99 #### Obtaining Your Automatically Generated DKIM DNS TXT Record
 100
 101 [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature sending and RSA keys generation are enabled by the default Postfix image `mwader/postfix-relay` with [OpenDKIM](http://www.opendkim.org/).
 102
 103 Run `cat ./docker-volume/opendkim/keys/*/*.txt` to display your DKIM DNS TXT Record containing the public key to configure to your domain :
 104
 105 ```bash
 106 $ cat ./docker-volume/opendkim/keys/*/*.txt
 107
 108 peertube._domainkey.mydomain.tld.       IN      TXT     ( "v=DKIM1; h=sha256; k=rsa; "
 109           "p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0Dx7wLGPFVaxVQ4TGym/eF89aQ8oMxS9v5BCc26Hij91t2Ci8Fl12DHNVqZoIPGm+9tTIoDVDFEFrlPhMOZl8i4jU9pcFjjaIISaV2+qTa8uV1j3MyByogG8pu4o5Ill7zaySYFsYB++cHJ9pjbFSC42dddCYMfuVgrBsLNrvEi3dLDMjJF5l92Uu8YeswFe26PuHX3Avr261n"
 110           "j5joTnYwat4387VEUyGUnZ0aZxCERi+ndXv2/wMJ0tizq+a9+EgqIb+7lkUc2XciQPNuTujM25GhrQBEKznvHyPA6fHsFheymOuB763QpkmnQQLCxyLygAY9mE/5RY+5Q6J9oDOQIDAQAB" )  ; ----- DKIM key peertube for mydomain.tld
 111 ```

 113 #### Administrator password
