Aerospike

Aerospike is an open source distributed database. Aerospike is built on a
"shared nothing" architecture designed to reliably stores terabytes of data
with automatic fail-over, replication and cross data-center synchronization.

Documentation for Aerospike is available at http://aerospike.com/docs.

Using this Image

The following will run asd with all the exposed ports forward to the host machine.

docker run -tid --name aerospike -p 3000:3000 -p 3001:3001 -p 3002:3002 -p 3003:3003 aerospike/aerospike-server

NOTE Although this is the simplest method to getting Aerospike up and running, but it is not the preferred method. To properly run the container, please specify an custom configuration with the access-address defined.

Advanced Usage

Custom Configuration

By default, asd will use the configuration file in /etc/aerospike/aerospike.conf, which is added to the directory by the Dockerfile. To provide a custom configuration, you should first mount a directory containing the file using the -v option for docker:

-v <DIRECTORY>:/opt/aerospike/etc

Where <DIRECTORY> is the path to a directory containing your custom configuration file. Next, you will want to tell asd to use a configuration file from /opt/aerospike/etc, by using the --config-file option for aerospike/aerospike-server:

--config-file /opt/aerospike/etc/aerospike.conf

This will use tell asd to use the file in /opt/aerospike/etc/aerospike.conf, which is mapped to <DIRECTORY>/aerospike.conf.

A full example:

docker run -tid -v <DIRECTORY>:/opt/aerospike/etc --name aerospike -p 3000:3000 -p 3001:3001 -p 3002:3002 -p 3003:3003 aerospike/aerospike-server --config-file /opt/aerospike/etc/aerospike.conf

access-address Configuration

In order for Aerospike to properly broadcast its address to the cluster or applications, the access-address needs to be set in the configuration file. If it is not set, then the IP address within the container will be used, which is not accessible to other nodes.

To specify access-address in aerospike.conf:

network {
    service {
        address any                  # Listening IP Address
        port 3000                    # Listening Port
        access-address 192.168.1.100 # IP Address to be used by applications
                                                                 # and other nodes in the cluster.
    }
    ...

Persistent Data Directory

With Docker, the files within the container are not persisted. To persist the data, you will want to mount a directory from the host to the guest's /opt/aerospike/data using the -v option:

-v <DIRECTORY>:/opt/aerospike/data

Where <DIRECTORY> is the path to a directory containing your data files.

A full example:

docker run -tid -v <DIRECTORY>:/opt/aerospike/data --name aerospike -p 3000:3000 -p 3001:3001 -p 3002:3002 -p 3003:3003 aerospike/aerospike-server

Clustering

Aerospike recommends using multicast clustering whenever possible, however, we are currently working to figure out how to best support multicast via Docker. For the time being, it will be best to setup Mesh Clustering. We are open to pull-requests with proposals on how to implement multicast for our Dockerfile.

Mesh Clustering

Mesh networking requires setting up links between each node in the cluster. This can be achieved in two ways:

  1. Define a configuration for each node in the cluster, as defined in Network Heartbeat Configuration.

  2. Use asinfo to send the tip command, to make the node aware of another node, as defined in tip command in asinfo.

Supported Docker versions

This image is officially supported on Docker version 1.4.1.

Support for older versions (down to 1.0) is provided on a best-effort basis.

User Feedback

Issues

Contributing

You are invited to contribute new features, fixes, or updates, large or small; we are always thrilled to receive pull requests, and do our best to process them as fast as we can.

Before you start to code, we recommend discussing your plans on the Aerospike Forums or through a GitHub issue, especially for more ambitious contributions. This gives other contributors a chance to point you in the right direction, give you feedback on your design, and help you find out if someone else is working on the same thing.
