Based on ubuntu:16.04. Installed from official packages.

Current stable version production ready.

Riak KV 2.9.2

Current tags: latest, 2.9, 2.9.2

Based on debian:buster-slim compiled with OpenSSL 1.0.2u (20-Dec-2019) and Basho's Erlang OTP 16

First post-basho version. Use at your own risk. Release notes.

###Default storage LevelDB (tiered, level 4), use RIAK_STORAGE_BACKEND variable to override.

Run with docker-compose

The environment variables below in example docker-compose.yml is set by default, therefore, you can run riak without specifying any parameters or variables just like that: docker run -d kefirgames/riak:2.2.3. And it will work fine.

Additional default variables

HOST=hostname -i - the default ipv4 address riak will serve on.

RIAK_SET_ULIMIT=262144 - a kind of workaround to set ulimit before riak starts (because docker --ulimit nofile=90000:90000 don't works here).

RIAK_CHECKCONFIG=True - run riak chkconfig before start, may be set to False if needed.

RIAK_AUTOSTART=True - runs riak start; riak wait-for-service riak_kv, then post-start scripts from /etc/riak/poststart.d and then starts to read riak logs with tail -n 1024 --retry -f /var/log/riak/console.log /var/log/riak/error.log

Riak advanced.config

Default advanced.config file.

docker run -d -v /path/to/advanced.config:/etc/riak/advanced.config kefirgames/riak:2.2.3
