Subject [jira] [Created] (ACCUMULO-4706) Create official Accumulo Docker image
Date Wed, 13 Sep 2017 20:27:00 GMT
Mike Walch created ACCUMULO-4706:

             Summary: Create official Accumulo Docker image
                 Key: ACCUMULO-4706
             Project: Accumulo
          Issue Type: New Feature
          Components: scripts, start
    Affects Versions: 2.0.0
            Reporter: Mike Walch
            Assignee: Mike Walch

While there are some [Accumulo images|]
on DockerHub, it looks the majority of the them are designed to run a single-node Accumulo
instance in a Docker container for development and testing.

It would be great if Accumulo had an official image for running Accumulo processes in containers
on a production cluster.  The image could be be published as an official image 'apache/accumulo'
to DockerHub.  

In order to make this possible, I think work needs to be done to allow configuration to be
passed to the Accumulo process in the docker container without using configuration files (as
passing files to a running container is hard in Docker).  One way to do this is to add an
option called {{--upload-accumulo-site}} to 'accumulo init' command which is called outside
of Docker by the user.  This would set properties in accumulo-site.xml as system properties
in Zookeeper during Accumulo initialization.  Accumulo processes in Docker containers could
be started with minimal configuration by updating 'accumulo <service>' commands to have
a {{-o key=value}} option to override configuration.  These changes to Accumulo would enable
the following commands to start an Accumulo cluster in Docker:

accumulo init --upload-accumulo-site
docker pull apache/accumulo
docker run apache/accumulo master -o
docker run apache/accumulo tserver -o
docker run apache/accumulo monitor -o
docker run apache/accumulo tracer -o
