+The parsoid, restbase, proxy, web containers are based on [Ubuntu](https://hub.docker.com/_/ubuntu/) 16.04
+
+The ElasticSearch container has requirements reguarding `vm.max_map_count`, and thus you need to do the following:
+
+``` sh
+sysctl -w vm.max_map_count=262144
+```
+
+You can also permanently set this setting by putting the file `etc/sysctl.d/99-elasticsearch.conf` on the root filesystem and doing `sysctl -p` or rebooting.
