This adds acceptance tests for specifying extra hosts on Docker
containers. It also renames the repeating block from `hosts` to `host`,
which reads more naturally in the schema when multiple instances of the
block are declared.
favor of attempting to detect if the initial container ever enters
running state, and erroring out if not. It will re-check the container
once every 500ms for 15 seconds total; future work could make that
configurable.
Links cause there to be more than one name for a container to be
returned. As a result, only looking at the first element of the
container names could cause a container to not be found, leading
Terraform to remove it from state and attempt to recreate it.
the Docker API get those containers running. Otherwise when
you try to start a container linking to them, the start command
will fail, leading to an error.
Docker's API is huge and only a small subset is currently implemented,
but this is expected to grow over time. Currently it's enough to
satisfy the use cases of probably 95% of Docker users.
I'm preparing this initial pull request as a preview step for feedback.
My ideal scenario would be to develop this within a branch in the main
repository; the more eyes and testing and pitching in on the code, the
better (this would avoid a merge request-to-the-merge-request scenario,
as I figure this will be built up over the longer term, even before
a merge into master).
Unit tests do not exist yet. Right now I've just been focused on getting
initial functionality ported over. I've been testing each option
extensively via the Docker inspect capabilities.
