can someone explain me how can I fully customize greenlight directly on the server ?

Answer 1

Its for Greenlight V1.
After searching bit i found below steps to setup ruby on rails greenlight app on server.
If you already setup greenlight with docker then please stop docker.
for docker compose you need to run command docker-compose down. it will stop docker image and you will see 404 on your server .
You need to fork greenlight from github first then clone that project in server you can clone it anywhere on server just make sure your server is running on port 5000.
you can checkout more from here
This are all the commands I used to have greenlight running without docker which works for me
======================
apt-get install curl
sudo apt-get install gnupg2
curl -sSL https://rvm.io/mpapis.asc | sudo gpg2 --import -

cp greenlight.nginx /etc/bigbluebutton/nginx/greenlight.nginx
systemctl restart nginx
rake secret
(Copy the secret generated, you will need it for .env)
bbb-conf --secret
(Copy the URL and Secret, you will need it for .env)
cp sample.env .env
nano .env
(fill the Secret and BigBlueButton credentials you generated before)
RAILS_ENV=production rake db:migrate
rails assets:precompile
rails s -p 5000 -e production
=======================================
In this project do changes as you require and run server again.

Answer 2

first of all you must have installed greenlight installed on server
for changing the color of theme :
vim config/application.rb
scroll down and you will found following code just replace code of color with your desire:
# Default primary color if the user does not specify one
config.primary_color_default = "#116ceb"
# Default primary color lighten if the user does not specify one
config.primary_color_lighten_default = "#e8eff9"
# Default primary color darken if the user does not specify one.
config.primary_color_darken_default = "#316cbe"
there is lots of things you can customize..(almost everything).
And one of the most important thing after making changes to any file you must have to rebuild your image of docker you can do that by running the command which is given at the end.
This command is for default settings if you have changed the name of your image please replace bigbluebutton/greenlight release-v2 with yourimage name.
you will find your image name here:
#this will open the yml file for docker settings
vim docker-compose.yml
#file will look like this:
ersion: '3'
services:
app:
entrypoint: [bin/start]
image: bigbluebutton/greenlight:release-v2 #nmae of your image
container_name: greenlight-v2
env_file: .env
restart: unless-stopped
ports:
- 127.0.0.1:5000:80
copy this command and past into the terminal blow command for rebuilding your docker image
docker-compose down && ./scripts/image_build.sh bigbluebutton/greenlight release-v2 && docker-compose up -d
