    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:

    aliyun shell

    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

    aliyun docker verify

    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.

    Start the mongodb replica

    Run:

    docker compose up -d mongo-init-replica

    This container's job is just to run the command to initialize the replica set. It will run the command and remove itself (it will not stay running)

    Start your Rocket.Chat server

    Now start the Rocket.Chat server:

    docker compose up -d rocketchat

    Rocket.Chat should be ready in a minute or two.

    Access your Rocket.Chat on Aliyun

    Your Rocket.Chat server can now be accessed over the Internet via:

    http://your-ip-address:8818/
