That is an odd error, certainly works locally but not when docker hub runs
the test setup.

One thing it could be is that if docker hub are using default EC2
instances, they have the vm.max_map_count set too low for Elasticsearch. It
is high enough that Elasticsearch will boot but not enough to stop it
erroring out after a very short period. I've been using 'sudo sysctl -w
vm.max_map_count=262144' on the host to avoid this which is why it is not
erroring for me during Elasticsearch's bootstrap checks.

We should be able to disable the checks (turn them from hard errors to soft
warnings in the logs) by passing the ES container
"discovery.type=single-node" as an environment variable. I'll try this on
my docker hub account and see if that can fix it.
