Control Center Docker Image

This page describes how to run Control Center with Docker.

GridGain provides two docker images: Control Center Frontend and Control Center Backend. The easiest way to start Control Center in Docker is to use docker-compose, which enables you to start multi-container applications with a single configuration file.

Prerequisites

Docker and Docker compose

Compose File

Docker Compose needs a configuration files that defines an application. In our case, the application consists of two containers: Control Center Backend and Control Center Frontend. The frontend uses nginx to redirect user requests and, therefore, needs an nginx configuration file.

The docker-compose file must define the following actions:

Pull docker images for Control Center Frontend and Control Center Backend:

docker image pull gridgain/control-center-frontend:2024.4
docker image pull gridgain/control-center-backend:2024.4

Mount nginx configuration file control-center.conf, which is used by the frontend to handle user requests (see below for a sample nginx configuration file).

control-center.conf

upstream backend-endpoint {
  server control-center-backend:3000;
}

server {
  listen 8008;
  server_name _;

  set $ignite_console_dir /data/www;

  root $ignite_console_dir;

  error_page 500 502 503 504 /50x.html;

  location / {
    try_files $uri /index.html = 404;
  }

  location /api/v1 {
    proxy_pass http://backend-endpoint;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-Host $http_host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass_header X-XSRF-TOKEN;
  }

  location /agents {
    proxy_pass http://backend-endpoint;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Origin http://backend-endpoint;
  }

  location /browsers {
    proxy_pass http://backend-endpoint;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Origin http://backend-endpoint;
    proxy_pass_header X-XSRF-TOKEN;
  }

  location = /50x.html {
    root $ignite_console_dir/error_page;
  }
}

Set configuration parameters via environment variables.
Start the backend and frontend containers and bind the frontend to port 8008.
```
docker compose up -d
```

Following is an example docker-compose file:

docker-compose.yaml

version: '3'
services:
  backend:
    image: gridgain/control-center-backend:2024.4
    container_name: control-center-backend
    # Restart on crash.
    restart: on-failure
    environment:
      # Java settings
      - JVM_OPTS=

  frontend:
    image: gridgain/control-center-frontend:2024.4
    container_name: control-center-frontend
    depends_on:
      - backend
    volumes:
      - ${PWD}/control-center.conf:/etc/nginx/control-center.conf
    ports:
      # Proxy HTTP Nginx port (HOST_PORT:DOCKER_PORT)
      - 8008:8008

Optionally, to introduce a custom ignite-config.xml file, mount the config map as follows:

services:
  backend:
    image: gridgain/control-center-backend:{version}
    container_name: control-center-backend
    # Restart on crash.
    restart: on-failure
    environment:
      # Java settings
      - JVM_OPTS=
    volumes:
      - ${PWD}/ignite-config.xml:/opt/gridgain-control-center/ignite-config.xml

Launching Control Center

Put docker-compose.yaml and control-center.conf into a directory and run the following command in that directory:

docker compose up -d

The command starts two containers and binds the frontend container to port 8008. Run the following command to verify that the containers launched successfully:

$ docker-compose ps
         Name                        Command               State                    Ports
-----------------------------------------------------------------------------------------------------------
control-center-backend    /bin/sh -c ./control-center.sh   Up      3000/tcp
control-center-frontend   nginx -g daemon off;             Up      80/tcp, 8008/tcp, 0.0.0.0:8008->8008/tcp

In the above example, Control Center is running on port 8008.

You have to launch Control Center from the admin account, which needs to be created:

Navigate to the Control Center backlog and find the "admin account" link:
Copy the link to your browser. Replace 3000 with 8008 and follows the link.
In the Control Center UI that appears, sign in the admin account and add the Control Center license.

The cluster will try to connect to the default Control Center URI (http://localhost:3000), which is the expected behavior. You can change the Control Center port using the management script:

{GRIDGAIN_HOME}/bin/management.sh --uri http://localhost:8008

See Control Center URI for details.

Configuration Parameters

You can set Control Center configuration parameters by providing environment variables in the docker-compose.yaml file.

For a complete list of parameters, see Configuration Parameters.

How to Add HTTPS to Control Center in Docker

To add HTTPS to Control Center, you need to prepare your the docker-compose file and nginx configuration for it to use:

Create a docker-compose.yaml file that uses certificate files:

version: '3'
services:
  backend:
    image: gridgain/control-center-backend:2024.4
    container_name: control-center-backend
    # Restart on crash.
    restart: on-failure
    environment:
      - JVM_OPTS=
    volumes:
      - ${PWD}/work:/opt/gridgain-control-center/work
  frontend:
    image: gridgain/control-center-frontend:2024.4
    container_name: control-center-frontend
    depends_on:
      - backend
    volumes:
      - ${PWD}/control-center.conf:/etc/nginx/control-center.conf
      - ${PWD}/server.crt:/etc/nginx/server.crt
      - ${PWD}/server.nopass.key:/etc/nginx/server.nopass.key
    ports:
      # Proxy HTTP Nginx port (HOST_PORT:DOCKER_PORT)
      - 80:8008
      - 443:8443

Create a control-center.conf nginx configuration file with the following content:

upstream backend-endpoint {
    server backend:3000;
}

server {
   listen 8008 default_server;
   listen [::]:8008 default_server;
   server_name _;
   return 301 https://$host$request_uri;
}

server {
    listen 8443 ssl;
    server_name _;
    ssl_certificate         /etc/nginx/server.crt;
    ssl_certificate_key     /etc/nginx/server.nopass.key;
    # Enable Mutual SSL if disabled https will be used.
    #ssl_verify_client       on;
    ssl_protocols       TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;
    set $ignite_console_dir /data/www;
    root $ignite_console_dir;

    error_page 500 502 503 504 /50x.html;

    location / {
        try_files $uri /index.html = 404;
    }

    location /api/v1 {
        proxy_pass http://backend-endpoint;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass_header X-XSRF-TOKEN;
    }

    location /browsers {
        proxy_pass http://backend-endpoint;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Origin http://backend-endpoint;
        proxy_pass_header X-XSRF-TOKEN;
    }

    location /agents {
        proxy_pass http://backend-endpoint;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Origin http://backend-endpoint;
    }

    location = /50x.html {
        root $ignite_console_dir/error_page;
    }
}

Generate your certificate files: server.crt and server.key.
Start Control Center:
docker compose up

Upgrading from a Previous Control Center Version

To migrate data from an existing Control Center installation to a new version:

Mount the work directory for the old installation.
Use the same work directory in the new Control Center version.
Do one of the following:
- Add the following property to application.properties or application.yaml:
  control.repositories.auto-migrate-enabled=true
- Launch Control Center with the following JVM_OPTS environment variable:
  -Dcontrol.repositories.auto-migrate-enabled=true
  For example, you can launch it from the command line like this:
  JVM_OPTS='-Dcontrol.repositories.auto-migrate-enabled=true' ./control-center.sh
