Deploy NebulaGraph with Docker Compose

Using Docker Compose can quickly deploy NebulaGraph services based on the prepared configuration file. It is only recommended to use this method when testing functions of NebulaGraph.

Prerequisites

  • If you are deploying NebulaGraph as a non-root user, grant the user with Docker-related privileges. For detailed instructions, see Manage Docker as a non-root user.
  • You have started the Docker service on your host.
  • If you have already deployed another version of NebulaGraph with Docker Compose on your host, to avoid compatibility issues, you need to delete the nebula-docker-compose/data directory.

How to deploy and connect to NebulaGraph

  1. Clone the 3.0.1 branch of the nebula-docker-compose repository to your host with Git.

    Danger

    The master branch contains the untested code for the latest NebulaGraph development release. DO NOT use this release in a production environment.

    $ git clone -b v3.0.1 https://github.com/vesoft-inc/nebula-docker-compose.git

  2. Go to the nebula-docker-compose directory.

    $ cd nebula-docker-compose/

  3. Run the following command to start all the NebulaGraph services.

    Note

    Update the NebulaGraph images and Nebula Console images first if they are out of date.

    [nebula-docker-compose]$ docker-compose up -d
Creating nebula-docker-compose_metad0_1 ... done
Creating nebula-docker-compose_metad2_1 ... done
Creating nebula-docker-compose_metad1_1 ... done
Creating nebula-docker-compose_graphd2_1   ... done
Creating nebula-docker-compose_graphd_1    ... done
Creating nebula-docker-compose_graphd1_1   ... done
Creating nebula-docker-compose_storaged0_1 ... done
Creating nebula-docker-compose_storaged2_1 ... done
Creating nebula-docker-compose_storaged1_1 ... done

    Note

    For more information of the preceding services, see NebulaGraph architecture.

  4. Connect to NebulaGraph.

    1. Run the following command to start a new docker container with the Nebula Console image, and connect the container to the network where NebulaGraph is deployed (nebula-docker-compose_nebula-net).

      $ docker run --rm -ti --network nebula-docker-compose_nebula-net --entrypoint=/bin/sh vesoft/nebula-console:v3.0.0

      Note

      The local network may be different from the nebula-docker-compose_nebula-net in the above example. Use the following command.

      $ docker network  ls
NETWORK ID          NAME                               DRIVER              SCOPE
a74c312b1d16        bridge                             bridge              local
dbfa82505f0e        host                               host                local
ed55ccf356ae        nebula-docker-compose_nebula-net   bridge              local
93ba48b4b288        none                               null                local

    2. Connect to NebulaGraph with Nebula Console.

      docker> nebula-console -u <user_name> -p <password> --address=graphd --port=9669

      Note

      By default, the authentication is off, you can only log in with an existing username (the default is root) and any password. To turn it on, see Enable authentication.

    3. Run the following commands to make the nebula-storaged processes to the available state.

      nebula> ADD HOSTS "storaged0":9779,"storaged1":9779,"storaged2":9779;

nebula> SHOW HOSTS;
+-------------+------+----------+--------------+----------------------+------------------------+---------+
| Host        | Port | Status   | Leader count | Leader distribution  | Partition distribution | Version |
+-------------+------+----------+--------------+----------------------+------------------------+---------+
| "storaged0" | 9779 | "ONLINE" | 0            | "No valid partition" | "No valid partition"   | "3.0.1" |
| "storaged1" | 9779 | "ONLINE" | 0            | "No valid partition" | "No valid partition"   | "3.0.1" |
| "storaged2" | 9779 | "ONLINE" | 0            | "No valid partition" | "No valid partition"   | "3.0.1" |
+-------------+------+----------+--------------+----------------------+------------------------+---------+

      Note

      Starting from NebulaGraph version 3.0.0, the nebula-storaged service reported to metad needs to execute 'ADD HOSTS' manually before it can be used.

  5. Run exit twice to switch back to your terminal (shell). You can run Step 4 to log in to NebulaGraph again.

Check the NebulaGraph service status and ports

Run docker-compose ps to list all the services of NebulaGraph and their status and ports.

$ docker-compose ps
Name                     Command                       State                                                   Ports

NebulaGraph provides services to the clients through port 9669 by default. To use other ports, modify the docker-compose.yaml file in the nebula-docker-compose directory and restart the NebulaGraph services.

Check the service data and logs

All the data and logs of NebulaGraph are stored persistently in the nebula-docker-compose/data and nebula-docker-compose/logs directories.

The structure of the directories is as follows:

nebula-docker-compose/
  |-- docker-compose.yaml
  ├── data
  │   ├── meta0
  │   ├── meta1
  │   ├── meta2
  │   ├── storage0
  │   ├── storage1
  │   └── storage2
  └── logs
      ├── graph
      ├── graph1
      ├── graph2
      ├── meta0
      ├── meta1
      ├── meta2
      ├── storage0
      ├── storage1
      └── storage2

Stop the NebulaGraph services

You can run the following command to stop the NebulaGraph services:

$ docker-compose down

The following information indicates you have successfully stopped the NebulaGraph services:

Stopping nebula-docker-compose_graphd2_1   ... done
Stopping nebula-docker-compose_graphd1_1   ... done
Stopping nebula-docker-compose_graphd_1    ... done

Removing nebula-docker-compose_metad1_1    ... done
Removing nebula-docker-compose_metad2_1    ... done
Removing network nebula-docker-compose_nebula-net

Danger

The parameter -v in the command docker-compose down -v will delete all your local NebulaGraph storage data. Try this command if you are using the nightly release and having some compatibility issues.

Modify configurations

The configuration file of NebulaGraph deployed by Docker Compose is nebula-docker-compose/docker-compose.yaml. To make the new configuration take effect, modify the configuration in this file and restart the service.

For more instructions, see Configurations.

FAQ

How to fix the docker mapping to external ports?

To set the ports of corresponding services as fixed mapping, modify the docker-compose.yaml in the nebula-docker-compose directory. For example:

graphd:
    image: vesoft/nebula-graphd:v3.0.1
    ...
    ports:
      - 9669:9669
      - 19669
      - 19670

9669:9669 indicates the internal port 9669 is uniformly mapped to external ports, while 19669 indicates the internal port 19669 is randomly mapped to external ports.

How to upgrade or update the docker images of NebulaGraph services

  1. In the nebula-docker-compose/docker-compose.yaml file, change all the image values to the required image version.

  2. In the nebula-docker-compose directory, run docker-compose pull to update the images of the Graph Service, Storage Service, and Meta Service.

  3. Run docker-compose up -d to start the NebulaGraph services again.

  4. After connecting to NebulaGraph with Nebula Console, run SHOW HOSTS GRAPH, SHOW HOSTS STORAGE, or SHOW HOSTS META to check the version of the responding service respectively.

ERROR: toomanyrequests when docker-compose pull

You may meet the following error.

ERROR: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit.

You have met the rate limit of Docker Hub. Learn more on Understanding Docker Hub Rate Limiting.

How to update the Nebula Console client
