Collaboration worker

The Collaboration Worker is a separate application intended to relieve Collaboration Server On-Premises of high CPU consumptive tasks. Using this service is optional.

We recommend using this service in large scale deployments to improve reliability. If it is possible, you should run this container on a separate machine.

# Scaling

The only requirement to make the services working together is connecting them to the same Redis and SQL database. You can run multiple worker instances and all of them will be available for Collaboration Server On-Premises instances.

Furthermore, we recommend disabling a built-in Collaboration Worker in Collaboration Server On-Premises if the external is available. You can do it by setting a USE_BUILT_IN_COLLABORATION_WORKER environment variable to false.

# Example with docker-compose

The steps are similar as in the case of regular Collaboration Server On-Premises installation.

1. If you have the docker-compose.yml file already, you can only add worker-cs service and set USE_BUILT_IN_COLLABORATION_WORKER environment variable to false in ckeditor-cs. Otherwise, create the file with content:

version: "3.7"
services:
  mysql-database:
    image: mysql:5.7.38
    platform: linux/amd64
    environment:
      MYSQL_ROOT_PASSWORD: password
    volumes:
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql:ro

  redis:
    image: redis:6.2.7

  ckeditor-cs:
    image: docker.cke-cs.com/cs:[version]
    depends_on:
      - redis
      - mysql-database
    ports:
      - "8000:8000"
    restart: always
    init: true
    environment:
      DATABASE_DRIVER: mysql
      DATABASE_HOST: mysql-database
      DATABASE_USER: root
      DATABASE_PASSWORD: password
      REDIS_HOST: redis
      ENVIRONMENTS_MANAGEMENT_SECRET_KEY: secret
      LICENSE_KEY: your_license_key
      STORAGE_DRIVER: filesystem
      STORAGE_LOCATION: /var/cs/easyimage
      USE_BUILT_IN_COLLABORATION_WORKER: "false"
    volumes:
      - ~/easyimage_files:/var/cs/easyimage

  worker-cs:
    image: docker.cke-cs.com/cs-worker:[version]
    restart: always
    init: true
    environment:
      DATABASE_DRIVER: mysql
      DATABASE_HOST: mysql-database
      DATABASE_USER: root
      DATABASE_PASSWORD: password
      REDIS_HOST: redis

2. Create the init.sql file:

     CREATE DATABASE `cs-on-premises`
     DEFAULT CHARACTER SET utf8mb4
     DEFAULT COLLATE utf8mb4_unicode_ci;
   

3. Run:

   docker-compose up
