Install with Docker

The recommended way of using ArangoDB is via ArangoDB Docker images with, for instance, Docker Desktop .

You can choose one of the following:

• arangodb official Docker images , verified and published by Docker.
• arangodb/arangodb Docker images , maintained and directly published by ArangoDB on a regular basis.

Check also the following resources:

• Manually starting a stand-alone instance via Docker
• Manually starting an Active Failover deployment via Docker
• Manually starting a Cluster via Docker

Start an ArangoDB instance

In order to start an ArangoDB instance, run:

docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 -d --name arangodb-instance arangodb

Note that on macOS/ARM, the default chosen processor architecture may not be the best choice. To override this, you can pass the --platform flag to the command, specifying the operating system and architecture you want to build for:

docker run --platform linux/arm64/v8 -p 8529:8529 -e ARANGO_ROOT_PASSWORD=1 arangodb-instance arangodb

This creates and launches the ArangoDB Docker instance as a background process. The identifier of the process is printed. By default, ArangoDB listens on port 8529 for requests and the image includes EXPOSE 8529. If you link an application container, it is automatically available in the linked container.

In order to get the IP ArangoDB listens on, run:

docker inspect --format '{{ .NetworkSettings.IPAddress }}' arangodb-instance

Using the instance

To use the running instance from an application, link the container:

docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 --name my-app --link arangodb-instance:db-link arangodb

This uses the instance named arangodb-instance and links it into the application container. The application container contains the following environment variables, which can be used to access the database.

DB_LINK_PORT_8529_TCP=tcp://172.17.0.17:8529
DB_LINK_PORT_8529_TCP_ADDR=172.17.0.17
DB_LINK_PORT_8529_TCP_PORT=8529
DB_LINK_PORT_8529_TCP_PROTO=tcp
DB_LINK_NAME=/naughty_ardinghelli/db-link

Exposing the port to the outside world

If you want to expose the port to the outside world, run:

docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 -p 8529:8529 -d arangodb

ArangoDB listens on port 8529 for requests and the image includes EXPOSE 8529. The -p 8529:8529 exposes this port on the host.

Choosing an authentication method

The ArangoDB image provides several authentication methods which can be specified via environment variables (-e) when using docker run.

1. ARANGO_RANDOM_ROOT_PASSWORD=1

   Generates a random root password when starting. The password is printed to stdout (and may be inspected later using docker logs).

2. ARANGO_NO_AUTH=1

   Disables authentication. Useful for testing.

   Disabling authentication in production environments exposes all your data. Make sure that ArangoDB is not directly accessible from the internet.

3. ARANGO_ROOT_PASSWORD=somepassword

   Specify your own root password.

Command line options

You can pass arguments to the ArangoDB server by appending them at the end of the Docker command.

docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 arangodb --help

The entry point script starts the arangod binary by default and forwards your arguments.

You may also start other binaries, such as the ArangoDB Shell (arangosh):

docker run -it arangodb arangosh --server.database myDB ...

Note that you need to set up networking for containers if arangod runs in one container and you want to access it with arangosh running in another container. It is easier to execute it in the same container instead. Use docker ps to find out the container ID or the name of a running container:

docker ps
CONTAINER ID   IMAGE     COMMAND                 CREATED      STATUS      PORTS                   NAMES
1234567890ab   arangodb  "/entrypoint.sh aran…"  2 hours ago  Up 2 hours  0.0.0.0:8529->8529/tcp  jolly_joker

Then, use docker exec and the ID or name to run something inside of the existing container:

docker exec -it jolly_joker arangosh

For more information, see the Configuration section.

Limiting resource utilization

arangod checks the following environment variables, which can be used to restrict how much memory and how many CPU cores it should use.

• ARANGODB_OVERRIDE_DETECTED_TOTAL_MEMORY (introduced in v3.6.3)

  This variable can be used to override the automatic detection of the total amount of RAM present in the system. You can specify a decimal number (in bytes). Furthermore, if G or g is appended, the value is multiplied by 2^30. If M or m is appended, the value is multiplied by 2^20. If K or k is appended, the value is multiplied by 2^10. That is, 64G meaning 64 gigabytes.

  The total amount of RAM detected is logged as an INFO message at server start. If the variable is set, the overridden value is shown. Various default sizes are calculated based on this value (i.e. RocksDB buffer cache size).

  Setting this option can be useful in two cases:

  • If arangod is running in a container and its cgroup has a RAM limitation, then you should specify this limitation in this environment variable, since it is currently not automatically detected.

  • If arangod is running alongside other services on the same machine and thus sharing the RAM with them, you should limit the amount of memory using this environment variable.

• ARANGODB_OVERRIDE_DETECTED_NUMBER_OF_CORES (introduced in v3.7.1)

  This variable can be used to override the automatic detection of the number of CPU cores present on the system.

  The number of CPU cores detected is logged as an INFO message at server start. If the variable is set, the overridden value is shown. Various default values for threading are calculated based on this value.

  Setting this option is useful if arangod is running in a container or alongside other services on the same machine and shall not use all available CPUs.

Using host directories

You can map the container’s volumes to a directory on the host, so that the data is kept between the runs of the container.

mkdir /tmp/arangodb
docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 -p 8529:8529 -d \
    -v /tmp/arangodb:/var/lib/arangodb3 \
    arangodb

This uses the /tmp/arangodb directory of the host as database directory for ArangoDB inside the container.

Using a data container

Alternatively, you can create a container holding the data and use this data container in your ArangoDB container.

docker create --name arangodb-persist arangodb true

docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 --volumes-from arangodb-persist -p 8529:8529 arangodb

If you want to save a few bytes, you can alternatively use busybox  or alpine  for creating the volume containers. Note that you need to provide the used volumes in this case.

docker run -d --name arangodb-persist -v /var/lib/arangodb3 busybox true

Using as a base image

If you use the image as a base image, make sure to write any CMD instructions in the exec form . Otherwise, the default entry point will not do its bootstrapping work.

When deriving the image, you can control the instantiation via putting files into /docker-entrypoint-initdb.d/.

• *.sh - files having this extension are run as a bash shell script.
• *.js - files having this extension are executed with arangosh. You can specify additional arangosh arguments via the ARANGOSH_ARGS environment variable.
• dumps/ - in this directory you can place subdirectories containing database dumps generated using arangodump. They can be restored using arangorestore.
