Merges in changes from our ES7 branch, and drops support for ES5.
This is a breaking change due to the upgrade, we have a ES5 branch at the commit before this.
These tests verify that, given an index settings and mappings, data can be written to the index, and read from it with a query_all query. These are very simple sanity tests.
We can, and should, write more complex tests that specific to each index in the future.
* Make docker files easier to use during development.
During development it quite nice to have docker work with locally built code. This allows you to launch all services very quickly, with your changes, and optionally with debugging support.
Changes made to docker files:
- Removed all redundant docker-compose files. We now have 1 giant file, and smaller files to use as overrides.
- Remove redundant README files that provided little information.
- Rename docker/<dir> to match the service name in the docker-compose file for clarity.
- Move environment variables to .env files. We only provide dev / the default environment for quickstart.
- Add debug options to docker files using multistage build to build minimal images with the idea that built files will be mounted instead.
- Add a docker/dev.sh script + compose file to easily use the dev override images (separate tag; images never published; uses debug docker files; mounts binaries to image).
- Added docs/docker documentation for this.
