Notes

I'm pretty sure this isn't the right location for this file as the SOLR and Memcached samples appear to be used as test data for a test.
Please advice if there's a better location to host this example?

I rebased this and brought it up, but there are no manual testing instructions to determine if elasticsearch is doing something we want it to do. Could you please edit the OP to provide manual testing instructions?

I can't wait to use this... thanks for your work!

@mkrauser your review on this would help get it pulled. How does it work for you? Let me know if you need help knowing how to get it or whatever.

Rebased to current upstream/master.

@rfay Disclaimer: I just started using ddev some weeks ago and I'm not a pro with elastic-search (but we will need that for a project really soon)

I gave it a shot on MacOS 10.14.2:
Adding ElasticSearch to the project worked like expected, just copy the docker-compose-file to .ddev and fire it up. ES is then reachable from the web-container and from the host. I put some sample-data in ES (downloaded from https://www.elastic.co/guide/en/kibana/current/tutorial-load-dataset.html) and started a local kibana installation.
Everything worked as expected, no crashes or issues of any kind.

One Question: Is the ES-Config adjustable like for the webservers? Since ES can be configured in so many ways, this would be really good to have this option.

And I would really love to see a Kibana-Installation bundled here. But that's in no way a show-stopper for this.

@thursdaybw Good work! Thanks again

[rfay]

Thanks so much for taking that for a spin.
The config basically in your hands; I think if I wanted extra config, I'd want to add a bind-mount that mounted that config, and there's none in this example.

We were never able to get a community review on this, or a response from @thursdaybw so moved this to Stack Overflow at https://stackoverflow.com/questions/54575785/how-can-i-use-an-elasticsearch-add-on-container-service-with-ddev/54575786#54575786 - hopefully it can incubate there.

Thanks for the contribution @thursdaybw and I hope it's working for you and look forward to more of these, and hope you'll "watch" the SO article and help people there.
