Running Rocket.chat with docker

In this post, I show how to run Rocket.chat meteor app in multiple setups.

Contents

On a single machine
In docker swarm
On a single machine with SSL TLS 1.2
In docker swarm with SSL TLS 1.2

1. On a single machine

Run a mongo container and name it db.
Run a rocket.chat container and link it to db with the name mongo, inside the rocket.chat container, the address http://mongo reaches the mongo container.
The rocket.chat container is named chat and is binded to port 3000.

To access rocket.chat, enter the address: http://ip_address_of_the_machine_running_docker:3000/

docker run --name db -d mongo --smallfiles
docker run --name chat -p 3000:3000 --link db:mongo -d rocketchat/rocket.chat

To stop rocket.chat:

docker stop chat db

To restart rocket.chat:

docker start db
# wait a few seconds
docker start chat

2. In docker swarm

For docker swarm setup see this post.

My docker swarm manager has ip:port=172.16.43.199:3456 and the overlay network is named my-net.

Run a mongo container connected to my-net and name it mongo, the address http://mongo reaches the mongo container.
Run a rocket.chat container connected to my-net.
The rocket.chat container is named chat and is binded to port 3000.

To access rocket.chat, enter the address: http://ip_address_of_the_machine_running_the_rocket_chat_container:3000/

docker -H tcp://172.16.43.199:3456 run -d --name=mongo --net=my-net mongo --smallfiles
docker -H tcp://172.16.43.199:3456 run --name chat -p 3000:3000 -d --net=my-net rocketchat/rocket.chat

To get the address of node running rocket.chat, run:

docker -H tcp://172.16.43.199:3456 ps

To stop rocket.chat:

docker -H tcp://172.16.43.199:3456 stop chat mongo

To restart rocket.chat:

docker -H tcp://172.16.43.199:3456 start mongo
# wait a few seconds
docker -H tcp://172.16.43.199:3456 start chat

3. On a single machine with SSL TLS 1.2

Run a mongo container and name it db.
Run a rocket.chat container and link it to db with the name mongo, inside the rocket.chat container, the address http://mongo reaches the mongo container.
Run a stud container and link it to the rocket.chat with the name app.

The stud docker image used in this setup is remynoulin/stud.

To create a self signed certificate, run this:

mkdir certs
openssl req -x509 -new -newkey rsa:2048 -nodes -keyout key.pem -out cert.pem
cat key.pem cert.pem > certs/ssl.pem

To access rocket.chat, enter the address: https://ip_address_of_the_machine_running_docker:3443/

docker run --name db -d mongo --smallfiles
docker run --name chat --link db:mongo -d rocketchat/rocket.chat
cd certs
docker run --name stud -p 3443:443 --link chat:app -v $(pwd):/opt/certs -d remynoulin/stud

To stop rocket.chat:

docker stop stud chat db

To restart rocket.chat:

docker start db
# wait a few seconds
docker start chat
docker start stud

4. In docker swarm with SSL TLS 1.2

For docker swarm setup see this post.

My docker swarm manager has ip:port=172.16.43.199:3456 and the overlay network is named my-net.

Run a mongo container connected to my-net and name it mongo, the address http://mongo reaches the mongo container.
Run a rocket.chat container connected to my-net.
Run a stud container connected to my-net.

The stud docker image used in this setup is remynoulin/stud.

To create a self signed certificate, run this:

mkdir certs
openssl req -x509 -new -newkey rsa:2048 -nodes -keyout key.pem -out cert.pem
cat key.pem cert.pem > certs/ssl.pem

To access rocket.chat, enter the address: https://ip_address_of_the_machine_running_the_rocket_chat_container:3443/

docker -H tcp://172.16.43.199:3456 run -d --name=mongo --net=my-net mongo --smallfiles
docker -H tcp://172.16.43.199:3456 run --name app -d --net=my-net rocketchat/rocket.chat
docker -H tcp://172.16.43.199:3456 run --name stud -p 3443:443 --net=my-net -d remynoulin/stud
docker -H tcp://172.16.43.199:3456 cp certs/ssl.pem stud:/opt/certs/ssl.pem
docker -H tcp://172.16.43.199:3456 start stud

To get the address of node running stud, run:

docker -H tcp://172.16.43.199:3456 ps

To stop rocket.chat:

docker -H tcp://172.16.43.199:3456 stop stud chat mongo

To restart rocket.chat:

docker -H tcp://172.16.43.199:3456 start mongo
# wait a few seconds
docker -H tcp://172.16.43.199:3456 start chat
docker -H tcp://172.16.43.199:3456 start stud
