Installation (short version)

On an Ubuntu 22.04 as the host machine.

Prerequisites

This machine needs to be updated and have installed:

Fetching the scripts

git clone https://github.com/jfederico/scalelite-run
cd scalelite-run

Initializing environment variables

Create a new .env file based on the dotenv file included.

cp dotenv .env

Most required variables are preset by default, the ones that must be set before starting are:

SECRET_KEY_BASE=
LOADBALANCER_SECRET=
URL_HOST=

Obtain the value for SECRET_KEY_BASE and LOADBALANCER_SECRET with:

sed -i "s/SECRET_KEY_BASE=.*/SECRET_KEY_BASE=$(openssl rand -hex 64)/" .env
sed -i "s/LOADBALANCER_SECRET=.*/LOADBALANCER_SECRET=$(openssl rand -hex 24)/" .env

Set the hostname on URL_HOST (E.g. sl.example.com)

sed -i "s/URL_HOST=.*/URL_HOST=sl.example.com" .env

Generate LetsEncrypt SSL certificates manually

source ./.env
certbot certonly --manual -d sl.$DOMAIN_NAME --agree-tos --no-bootstrap --manual-public-ip-logging-ok --preferred-challenges=dns --email <YOUR_ENMAIL> --server https://acme-v02.api.letsencrypt.org/director
certbot certonly --manual -d redis.$DOMAIN_NAME --agree-tos --no-bootstrap --manual-public-ip-logging-ok --preferred-challenges=dns --email <YOUR_ENMAIL> --server https://acme-v02.api.letsencrypt.org/director

Starting the app

Start the services.

docker-compose up -d

The database must be initialized.

docker exec -i scalelite-api bundle exec rake db:setup

The BBB servers must be added.

docker exec -i scalelite-api bundle exec rake servers:add[https://bbb25.example.com/bigbluebutton/api,secret]
docker exec -i scalelite-api bundle exec rake servers:enable[bbb25.example.com]

Setup recordings

Configuring the BBB server

Init the bbb server as explained in the documentation

Edit the /home/bigbluebutton/.ssh/config file

  1. make sure the configured domain points to your local machine as this user needs to ssh to it

  2. replace the default bigbluebutton with your own username (as you don't want to add bigbluebutton username to your local machine)

Host scalelite-spool HostName sl.jesus.blindside-dev.com User <YOUR_USERNAME> Port 22 IdentityFile /home/bigbluebutton/.ssh/id_rsa

  1. In your local machine, add the public key generated for the bigbluebutton user in the bbb machine into your own ~/.ssh/authorized_keys file.

  2. ssh into your own computer using the config env_file ssh scalelite-spool

  3. Edit the variable that indicates where the files will be placed

Edit /usr/local/bigbluebutton/core/scripts/scalelite.yml

# spool_dir: scalelite-spool:/var/bigbluebutton/spool 	## original
spool_dir: scalelite-spool:/home/<YOUR_USERNAME>/spool		## adapted

Accept the key, this is done only once.

Final touches in your Local Machine

  1. Make sure your user has rights to write in the /mnt/scalelite-recordings/var/bigbluebutton/spool/

sudo chown -R root.<YOUR_USERNAME> /mnt/scalelite-recordings/var/bigbluebutton/spool/

  1. Create a symbolic link to that spool directory

ln -s /mnt/scalelite-recordings/var/bigbluebutton/spool/ /home/YOUR_USERNAME/spool
