Gaffer Docker

What you have here, is a Docker container for Gaffer. This is a small instance and is really only useful only development / trial purposes. But containerising allows a quick way to find out what Gaffer is like and develop against the interfaces. The container deploys: Hadoop, Accumulo, Zookeeper, and launches Gaffer using Wildfly.

The memory settings of Accumulo are low to ensure Accumulo runs in a small footprint. Budget for around 2GB for trivial amounts of data, 6GB for anything with some load.

To run:

docker run -it -p 8080:8080 gchq/gaffer:0.4.4

You can then access the Gaffer API at port 8080:


and the prototype Gaffer UI at:


When the container dies, the data is lost. If you want data to persist, mount a volume on /data e.g.

docker run -it -p 8080:8080 -v /data/gaffer:/data gchq/gaffer:0.4.4

The default schema deployed is usable. If you want to set your own schema then you need to change /usr/local/wildfly/schema/* by e.g. mounting replacement volumes.

At high input load, Zookeeper seems to continually grow until it exhausts the container memory footprint.

In future, I will probably detangle Hadoop, Accumulo, Zookeeper and Gaffer into separate containers to run linked.
