deploying elasticsearch in LXD container fails

[Yoshi Kadokawa]

When deploying elasticsearch in LXD container, it will fail with the following error in /var/log/elasticsearch/elasticsearch.log

[1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

When elasticsearch package is installed, it will try to set the vm.max_map_count with the following sysctl file.

# cat /usr/lib/sysctl.d/elasticsearch.conf
vm.max_map_count=262144

However, since it is in LXD container, this can not be configured, unless this is configured from the host.

As an workaround, increasing vm.max_map_count value in the host will mitigate the issue.

Did you try to follow this doc https://github.com/lxc/lxd/blob/master/doc/production-setup.md to configure a set of value before lxd is initiated?
As we cannot configure this value in a container and can only configure on the host, is it still a bug for the container?
What do you think?
