Database docker image

The used database is Elasticsearch 8.4.x. This images is based on elasticsearch:8.4 from the offical Docker Library project and uses openjdk:8-jre-alpine as a base image.

Additionally the ICU Analysis Plugin is installed to provide unicode collation which is used for sorting.

Usage for testing purposes:

Run it with this command: docker run -d -p 9200:9200 registry.gitlab.com/openstapps/database:master

Currently there is an issue with elasticsearch and java on linux machines that temporarly can be solved by running: sudo sysctl -w vm.max_map_count=262144 on the host machine. On restart of the machine this parameter will reset. To set it permanently, you will have to add it to /etc/sysctl.conf on machines that run systemd as a init deamon.

For production use:

Please set vm.max_map_count=262144 permanently. It is explained here
