Rocket.chat and Caddy as reverse proxy using docker engine!

0. Requirements:

• own domain associated with the A/AAA record in DNS,
• open port 443 on the server,
• docker and docker-compose.

1. Clone repository.

Clone repository to your working directory. I prefer /srv to this.

cd /srv
git clone https://github.com/rvva/rocket.chat-caddy 

1a. [OPTIONAL] Customize docker-compose to suit your requirements

Go to rocket-chat working directory and edit docker-compose.yml with your favorite text editor.

vim /srv/rocket.chat-caddy/rocket.chat/docker-compose.yml

Editing variables is not required - it is optional.

2. Run RocketChat

Run docker compose inside rocket.chat working directory:

cd /srv/rocket.chat-caddy/rocket.chat/
docker-compose up --build -d

3. Setup Caddy reverse proxy with Let's Encrypt, ZeroSSL or self signed certificate.

Go to caddy working directory and edit Caddyfile.

vim /srv/rocket.chat-caddy/caddy/Caddyfile

Things you need to edit:

• email [email protected] to your valid email,
• mydomain.pl to your domain for rocket.chat,
• reverse_proxy 192.168.0.22:3000 point your local machine address (port 3000 is default for rocket.chat). You can check your local ip adress by command hostname -I | awk '{ print $1 }'

Another example:

{
    # Global options block. Entirely optional, https is on by default
    # Optional email key for lets encrypt
    email [email protected]
    # Optional staging lets encrypt for testing. Comment out for production.
    # acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
}
chat.red.com {
    reverse_proxy 10.0.44.1:3000
    # If you want to use self signed certifiacate insted Let's Encrypt uncomment section tls inernal
    # tls internal
}

If you want to use self signed certifiacate insted Let's Encrypt uncomment section tls inernal in Caddyfile.

Run docker compose inside caddy working directory:

cd /srv/rocket.chat-caddy/caddy/
docker-compose up --build -d

4. Extras

If you want to change Caddyfile configuration while caddy is running you need to reload configuration. You can use for that caddy-reload.sh which is stored in caddy working direcory or command :

docker exec -it caddy caddy reload --config /etc/caddy/Caddyfile

5. Logs

Remember logs are your friends. Check them if there are any problems.

docker logs -f caddy
docker logs -f rockerchat-www
docker logs -f rockerchat-db

6. Set up in 3 minutes.
