Docker image

[tsukhani]

Can someone provide instructions/documentation to create a docker image for the latest 3.x releases?

Hi,

Below is what I used with some success (of note remains an issue with the 'riak' user in the container, which runs the process, not mapping correctly to a 'riak' user in the host).

Some additional notes about the Dockerfile:

• Files mapping-FoldToASCII.txt and mapping-ISOLatin1Accent.txt were missing in the installation directory and Solr was not happy about it so I added them after installing from the deb packages.
• The riak.conf is changed to set some settings specifics to Search and are most likely not optimal
• The riak.conf is enabling inter-cluster replication
• The riak-kv-docker.sh startup script is used to set the nodename based on the fqdn of the machine, and also setting the advertised IP of the node for the inter-cluster replication module (this bit in a way very specific to my environment).

Why isn't basho doing this? This makes me think that ultimately the project maybe be dying or not have enough resources to handle basic things like docker containers. I was going to push Riak to the engineering manager but how can I explain they don't even have a container image?~?~~?

@bbqchickenrobot 2018 was a long time ago...
Riak is opensource. Feel free to contribute with a docker image

Ah, I didn't realize the history - shame.
