Deploying Rocket.Chat on Aliyun

You can install Rocket.Chat to Ubuntu VPS on Aliyun.

The recommended VPS configuration is:

2 GB RAM
10 GB disk
2 or 4 cores

However, lower performance configuration has been tested on a VPS with:

1 GB RAM
10 GB disk
1 core

Follow these steps to install Rocket.Chat.

Update Ubuntu repo lists and Install curl

After you ssh to the VPS:

Run the command:

apt-get update

followed by:

apt-get install curl

Install docker

Run this command:

curl -sSL https://get.docker.com/ | sh

Docker should be installed, verify it:

docker ps

Install docker-compose

Install docker-compose, follow the latest release instructions

For release 1.5.0, you can use:

curl -L https://github.com/docker/compose/releases/download/1.5.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

(if or when this is blocked, you'll have to obtain Linux-x86_64 docker-compose binary via other means)

Next, allow execution of docker-compose:

chmod +x /usr/local/bin/docker-compose

Create directories for Rocket.Chat

First,

mkdir /home/rocketchat

Then,

cd /home/rocketchat

Make two more directories for the mongodb database:

mkdir data
mkdir dump

Create customized docker-compose.yml

Create a docker-compose.yml file with the following content:

version: '2'

services:
  rocketchat:
    image: rocket.chat:latest
    restart: unless-stopped
    volumes:
      - ./uploads:/app/uploads
    environment:
      - PORT=3000
      - ROOT_URL=http://chat.inumio.com
      - MONGO_URL=mongodb://mongo:27017/rocketchat
      - MONGO_OPLOG_URL=mongodb://mongo:27017/local
      - Accounts_UseDNSDomainCheck=True
    depends_on:
      - mongo
    ports:
      - 8818:3000

  mongo:
    image: mongo
    restart: unless-stopped
    volumes:
     - $PWD/data:/data/db
     - $PWD/dump:/dump
    command: mongod --smallfiles --oplogSize 128 --replSet rs0 --storageEngine=mmapv1

  # this container's job is just run the command to initialize the replica set.
  # it will run the command and remove himself (it will not stay running)
  mongo-init-replica:
    image: mongo
    command: 'bash -c "for i in `seq 1 30`; do mongo mongo/rocketchat --eval \"rs.initiate({ _id: ''rs0'', members: [ { _id: 0, host: ''localhost:27017'' } ]})\" && s=$$? && break || s=$$?; echo \"Tried $$i times. Waiting 5 secs...\"; sleep 5; done; (exit $$s)"'
    depends_on:
      - mongo

Make sure you customize the file with your-ip-address in the MONGO_URL env variable.

Pull the required docker images

This will download the required docker images, and may take some time.

This is done only the first time, or when you want to update Rocket.Chat.

docker pull mongo
docker pull registry.rocket.chat/rocketchat/rocket.chat

Start the mongodb database

Run:

docker compose up -d mongo

Mongo supports 24 x 7 operations and live backup. You should not need to restart it too frequently. See mongodb documentations for proper operation and management of a mongo server.

Wait a couple of minute for mongo to start properly.
