This PR resurrects support for building Docker images based on one of Red Hat's UBI images. It also adds support for
running the existing Docker tests against the image. The image is named `elasticsearch-ubi8:<version>`.
I also changed the Docker build file uses enums instead strings in a lot of places, for added rigour.
- Replace immediate task creations by using task avoidance api
- One step closer to #56610
- Still many tasks are created during configuration phase. Tackled in separate steps
Docker informed us that for official multi-arch Docker builds, there
needs to be a single Dockerfile and build context that can be used for
each supported architecture. Therefore, rework the build to move the
relevant architecture logic into the Dockerfile, and merge the aarch64
/ x64 docker context builds.
Closes#48724. Update `.editorconfig` to make the Java settings the default
for all files, and then apply a 2-space indent to all `*.gradle` files.
Then reformat all the files.
Enable audit logs in docker by creating console appenders for audit loggers.
also rename field @timestamp to timestamp and add field `type` with value audit
The docker build contains now two log4j configuration for oss or default versions. The build now allows override the default configuration.
Also changed the format of a timestamp from ISO8601 to include time zone as per this discussion https://github.com/elastic/elasticsearch/pull/36833#discussion_r244225243closes#42666
