 # BigBlueButton Docker

-## Please note
- Not well tested, can be still really buggy. Don't use for production! 
-
 ## Install
 1. Install docker-ce & docker-compose
    1. follow instructions

-6. Create `.env` with `$ cp sample.env .env`
-7. Adjust the values in `.env`
-   - **Important:** don't forget to change `ETHERPAD_API_KEY`, `SHARED_SECRET` and `RAILS_SECRET` to any random values! For example generated with `pwgen 40 3`
-   - `DOMAIN` and `EXTERNAL_IP` are also required. For example, use `dig +short <DOMAIN>` to get your external ip address. 
-8. Start container. either...
-    - **Most common setup**: BigBlueButton with automatic HTTPS certificate retrieval and Greenlight
-        ```bash
-        $ docker-compose \
-            -f docker-compose.yml \
-            -f docker-compose.https.yml \
-            -f docker-compose.greenlight.yml \
-            up --detach
-        ```
-    - **Individual parts**:
-        - BigBlueButton `$ docker-compose up -d`
-        - HTTPS reverse proxy
-            - `$ docker-compose -f docker-compose.https.yml up -d`
-        - API demos
-            - `$ docker-compose -f docker-compose.demo.yml up -d`
-            - Access https://bbb.example.com/demo/
-        - Greenlight
-            - `$ docker-compose -f docker-compose.greenlight.yml up -d`
-            - Create an administrator account \
-            `$ docker exec greenlight-v2 bundle exec rake admin:create`
-            - Access https://bbb.example.com/b
+6. Run setup:
+   ```bash
+   $ ./scripts/setup
+   ```
+7. Start containers:
+    ```bash
+    $ ./scripts/compose up -d

+8. If you use greenlight, you can create an admin account with:
+    ```bash
+    $ ./scripts/compose exec greenlight bundle exec rake admin:create
+    ```

 ## Upgrading

-### Upgrade BigBlueButton
-```bash
-cd bbb-docker
-
-# pull repo changes
-git pull 
-
-# update bbb-webrtc-sfu
-git submodule update --remote 
-
-# rebuild images
-docker-compose build --pull --no-cache 
-
-# recreate updated services
-docker-compose up -d
-```
-
-### Upgrade Greenlight
-**Important:** especially with a version before 2020-05-17 create a database backup first, otherwise the data will not be persistent between container recreations.
 ```bash
 cd bbb-docker

+# if you use greenlight:
 # create a database backup
 docker exec -t docker_postgres_1 pg_dumpall -c -U postgres > /root/greenlight_`date +%d-%m-%Y"_"%H_%M_%S`.sql

-# pull repo changes
-git pull 
+# upgrade!
+./scripts/upgrade

-# pull image updates
-docker-compose -f docker-compose.greenlight.yml pull
-
-# recreate & restart services if necessary
-docker-compose -f docker-compose.greenlight.yml up -d
+# restart updated services
+./scripts/compose up -d
 ```

-### Upgrade HTTPS Proxy
-[to be written]
+If you're on an old version, you might get following error: \
+`no such file or directory: ./scripts/upgrade` \
+A simple `$ git pull` resolves that, by fetching a newer version which includes the upgrade script.

 ## Special thanks to
 - @dkrenn, whos dockerized version (bigbluebutton#8858)(https://github.com/bigbluebutton/bigbluebutton/pull/8858) helped me a lot in understand and some configs.

 ## Open Tasks
 - add support for recording
- further separate bbb-core into individual container
+- add coturn
+- add prometheus exporter
+- further separate `bbb-core` into individual container
 - enable IPv6 support
- fix captions (they don't appear, `readOnlyPadId` is missing)
- switch to `node:12-buster-slim` for `html5`
- switch to `node:12-buster-slim` for `webrtc-sfu` 
- drop root privileges in `webrtc-sfu`
- drop root privileges in `kurento`
+- switch `html5` to node v12
+- drop root privileges in `webrtc-sfu`
