Deploy Nebula Graph with Docker Compose¶
Using Docker Compose can quickly deploy Nebula Graph services based on the prepared configuration file. It is only recommended to use this method when testing functions of Nebula Graph.
Prerequisites¶
-
You have installed the following applications on your host.
Application Recommended version Official installation reference Docker Latest Install Docker Engine Docker Compose Latest Install Docker Compose Git Latest Download Git
- If you are deploying Nebula Graph 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 Nebula Graph with Docker Compose on your host, to avoid compatibility issues, you need to delete the
nebula-docker-compose/datadirectory.
How to deploy and connect to Nebula Graph¶
-
Clone the
masterbranch of thenebula-docker-composerepository to your host with Git.Danger
The
masterbranch contains the untested code for the latest Nebula Graph development release. DO NOT use this release in a production environment.$ git clone -b v2.5.0 https://github.com/vesoft-inc/nebula-docker-compose.git -
Go to the
nebula-docker-composedirectory.$ cd nebula-docker-compose/ -
Run the following command to start all the Nebula Graph services.
Note
Update the Nebula Graph images and Nebula Console images first if they are out of date.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 ... doneNote
For more information of the preceding services, see Nebula Graph architecture.
-
Connect to Nebula Graph.
-
Run the following command to start a new docker container with the Nebula Console image, and connect the container to the network where Nebula Graph is deployed (nebula-docker-compose_nebula-net).
$ docker run --rm -ti --network nebula-docker-compose_nebula-net --entrypoint=/bin/sh vesoft/nebula-console:v2.5.0Note
The local network may be different from the
nebula-docker-compose_nebula-netin 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 -
Connect to Nebula Graph with Nebula Console.
docker> nebula-console -u <user_name> -p <password> --address=graphd --port=9669Note
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. -
Run the
SHOW HOSTSstatement to check the status of thenebula-storagedprocesses.nebula> SHOW HOSTS; +-------------+------+----------+--------------+----------------------+------------------------+ | Host | Port | Status | Leader count | Leader distribution | Partition distribution | +-------------+------+----------+--------------+----------------------+------------------------+ | "storaged0" | 9779 | "ONLINE" | 0 | "No valid partition" | "No valid partition" | +-------------+------+----------+--------------+----------------------+------------------------+ | "storaged1" | 9779 | "ONLINE" | 0 | "No valid partition" | "No valid partition" | +-------------+------+----------+--------------+----------------------+------------------------+ | "storaged2" | 9779 | "ONLINE" | 0 | "No valid partition" | "No valid partition" | +-------------+------+----------+--------------+----------------------+------------------------+ | "Total" | | | 0 | | | +-------------+------+----------+--------------+----------------------+------------------------+

Run
exittwice to switch back to your terminal (shell). You can run Step 4 to log in to Nebula Graph again.
Check the Nebula Graph service status and ports¶
Run docker-compose ps to list all the services of Nebula Graph and their status and ports.
$ docker-compose ps

Nebula Graph 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 Nebula Graph services.
Check the service data and logs¶
All the data and logs of Nebula Graph 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 Nebula Graph services¶
You can run the following command to stop the Nebula Graph services:
$ docker-compose down
The following information indicates you have successfully stopped the Nebula Graph services:

Danger
The parameter -v in the command docker-compose down -v will delete all your local Nebula Graph storage data. Try this command if you are using the nightly release and having some compatibility issues.
Modify configurations¶
The configuration file of Nebula Graph 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:v2.5.0
...
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 update the docker images of Nebula Graph services¶
To update the images of the Graph Service, Storage Service, and Meta Service, run docker-compose pull in the nebula-docker-compose directory.
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¶
To update the Nebula Console client, run the following command.
docker pull vesoft/nebula-console:v2.5.0
How to upgrade Nebula Graph services¶
To upgrade Nebula Graph, update the Nebula Graph docker images and restart the services.
-
In the
nebula-docker-composedirectory, rundocker-compose pullto update the Nebula Graph docker images. -
Run
docker-compose downto stop the Nebula Graph services. -
Run
docker-compose up -dto start the Nebula Graph services again.
Why can’t I connect to Nebula Graph via port 3699 after updating the nebula-docker-compose repository (Nebula Graph 2.0.0-RC)?¶
In Nebula Graph 2.0.0-RC release, the default port is changed from 3699 to 9669. Please use port 9669 to connect to Nebula Graph, or modify the port in docker-compose.yaml.
Why can't I access the data after updating the nebula-docker-compose repository? (Jan 4, 2021)¶
If you have updated the nebula-docker-compose repository after Jan 4, 2021, and there are pre-existing data, modify the docker-compose.yaml file and change the port numbers to the previous ones before connecting to Nebula Graph.
Why can't I access the data after updating the nebula-docker-compose repository? (Jan 27, 2021)¶
The data format has been modified on Jan 27, 2021, and is incompatible with the previous data. Run docker-compose down -v to delete all your local data.
