# Database docker image

|
|
|
|
The used database is Elasticsearch 8.4.x. This images is based on
|
|
[elasticsearch:8.4](https://hub.docker.com/r/library/elasticsearch/) from the
|
|
[offical Docker Library project](https://docs.docker.com/docker-hub/official_repos/) and uses openjdk:8-jre-alpine as a
|
|
base image.
|
|
|
|
Additionally the [ICU Analysis Plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/8.4/analysis-icu.html) 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](https://www.elastic.co/guide/en/elasticsearch/reference/8.4/docker.html#docker-prod-prerequisites)
