Previously, in order to determine whether security had been disabled via environment variables in Docker, we were able to check the command line switches to the Elasticsearch process. That doesn't work now because Elasticsearch processes the environment variables itself. Therefore, change the check to look at the environment instead.

I don't think we need this now?

What do you think about also checking that the settings have the correct values as well?

Can we also please replicate DockerTests.test087EnvironmentVariablesInIncorrectFormatAreIgnored()? It checks that env vars, which look like maybe they ought to be respected, are ignored due to being malformed.
You'll also need to remove these tests from DockerTests, because they rely on being able to inspect the Elasticsearch command line for options:

There are a number of debug statements that need to be removed as well.

Thanks Rory! I think I have a addressed all your comments. I normally don't like javadoc comments on test methods and having super descriptive names (which are actually harder to read IMO becauseOfTheLongRunningCamelCaseThatIsHardToVisuallyParse ;) But I added some simple comments to each method to describe what they are checking and standardized on method naming. |
We were checked whether security was enabled or disabled in the environment by running the `env` command and passing it through `grep`. Unforunately, and somewhat obviously, `grep` exits non-zero if it doesn't find a match, which causes `Shell.run` to throw and exception. We could fix it with `runScriptIgnoreExitCode` instead of `run`, but instead I chose just fetch all the `env` values and check them in the Java code.

Thanks for the docker test fixes Rory. I think this is ready for a final review now that all tests are passing. |
