   1 # Docker guide
   2
   3 This guide requires [docker](https://www.docker.com/community-edition) and
   4 [docker-compose V2](https://docs.docker.com/compose/install/).
   5
   6 ```shell
   7 docker compose version # Must be > 2.x.x
   8 ```
   9
  10 ## Install
  11
  12 **PeerTube does not support webserver host change**. Keep in mind your domain
  13 name is definitive after your first PeerTube start.
  14
  15 #### Go to your workdir
  16
  17 :::info
  18 The guide that follows assumes an empty workdir, but you can also clone the repository, use the master branch and `cd support/docker/production`.
  19 :::
  20
  21 ```shell
  22 cd /your/peertube/directory
  23 ```
  24
  25 #### Get the latest Compose file
  26
  27 ```shell
  28 curl https://raw.githubusercontent.com/chocobozzz/PeerTube/master/support/docker/production/docker-compose.yml > docker-compose.yml
  29 ```
  30
  31 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)
  32
  33 #### Get the latest env_file
  34
  35 ```shell
  36 curl https://raw.githubusercontent.com/Chocobozzz/PeerTube/master/support/docker/production/.env > .env
  37 ```
  38
  39 View the source of the file you're about to download: [.env](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/.env)
  40
  41 #### Tweak the `docker-compose.yml` file there according to your needs
  42
  43 ```shell
  44 sudo nano docker-compose.yml
  45 ```
  46
  47 #### Then tweak the `.env` file to change the environment variables settings
  48
  49 ```shell
  50 sudo nano .env
  51 ```
  52
  53 In the downloaded example [.env](https://github.com/Chocobozzz/PeerTube/blob/master/support/docker/production/.env), you must replace:
  54 - `<MY POSTGRES USERNAME>`
  55 - `<MY POSTGRES PASSWORD>`
  56 - `<MY DOMAIN>` without 'https://'
  57 - `<MY EMAIL ADDRESS>`
  58 - `<MY PEERTUBE SECRET>`
  59
  60 Other environment variables are used in
  61 [/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
  62 intuited from usage.
  63
  64 #### Webserver
  65
  66 ::: info
  67 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.
  68 :::
  69
  70 Install the template that the nginx container will use.
  71 The container will generate the configuration by replacing `${WEBSERVER_HOST}` and `${PEERTUBE_HOST}` using your docker compose env file.
  72
  73 ```shell
  74 mkdir -p docker-volume/nginx
  75 curl https://raw.githubusercontent.com/Chocobozzz/PeerTube/master/support/nginx/peertube > docker-volume/nginx/peertube
  76 ```
  77
  78 You need to manually generate the first SSL/TLS certificate using Let's Encrypt:
  79
  80 ```shell
  81 mkdir -p docker-volume/certbot
  82 docker run -it --rm --name certbot -p 80:80 -v "$(pwd)/docker-volume/certbot/conf:/etc/letsencrypt" certbot/certbot certonly --standalone
  83 ```
  84
  85 A dedicated container in the docker-compose will automatically renew this certificate and reload nginx.
  86
  87
  88 #### Test your setup
  89
  90 _note_: Newer versions of compose are called with `docker compose` instead of `docker-compose`, so remove the dash in all steps that use this command if you are getting errors.
  91
  92 Run your containers:
  93
  94 ```shell
  95 docker compose up
  96 ```
  97
  98 #### Obtaining your automatically-generated admin credentials
  99
 100 You can change the automatically created password for user root by running this command from peertube's root directory:
 101 ```shell
 102 docker compose exec -u peertube peertube npm run reset-password -- -u root
 103 ```
 104
 105 You can also grep your peertube container's logs for the default `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.
 106
 107 ```bash
 108 docker compose logs peertube | grep -A1 root
 109
 110 peertube_1  | [example.com:443] 2019-11-16 04:26:06.082 info: Username: root
 111 peertube_1  | [example.com:443] 2019-11-16 04:26:06.083 info: User password: abcdefghijklmnop
 112 ```
 113
 114 #### Obtaining Your Automatically Generated DKIM DNS TXT Record
 115
 116 [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/).
 117
 118 Run `cat ./docker-volume/opendkim/keys/*/*.txt` to display your DKIM DNS TXT Record containing the public key to configure to your domain :
 119
 120 ```bash
 121 cat ./docker-volume/opendkim/keys/*/*.txt
 122
 123 peertube._domainkey.mydomain.tld.       IN      TXT     ( "v=DKIM1; h=sha256; k=rsa; "
 124           "p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0Dx7wLGPFVaxVQ4TGym/eF89aQ8oMxS9v5BCc26Hij91t2Ci8Fl12DHNVqZoIPGm+9tTIoDVDFEFrlPhMOZl8i4jU9pcFjjaIISaV2+qTa8uV1j3MyByogG8pu4o5Ill7zaySYFsYB++cHJ9pjbFSC42dddCYMfuVgrBsLNrvEi3dLDMjJF5l92Uu8YeswFe26PuHX3Avr261n"
 125           "j5joTnYwat4387VEUyGUnZ0aZxCERi+ndXv2/wMJ0tizq+a9+EgqIb+7lkUc2XciQPNuTujM25GhrQBEKznvHyPA6fHsFheymOuB763QpkmnQQLCxyLygAY9mE/5RY+5Q6J9oDOQIDAQAB" )  ; ----- DKIM key peertube for mydomain.tld
 126 ```
