I'm trying to get a single node docker node up and running for testing. It seems things have changed since 6.7 and it now aborts with a "the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured"
So, what's the magic docker incantation for a bog standard single node cluster intended for development?
BTW. I noticed the docker image has gotten progressively more fussy about settings over the 6.x release. It seems to want all sorts of configuration; which is appropriate for production use but not for development.
So, please update your documentation and error message to make it very clear how to run ES using docker for development (or as in my case, integration tests) as it currently isn't.
