We currently do not exercise container apps in our tests, the container
app seems to be an unused fixture. This commit introduces basic tests to
ensure that container apps are built and work as expected. Furthermore,
this commit introduces a check that container args actually work.
Finally, this commit removes the
build_env
keyword from theContainerImage
class. Docker has no concept of specifying environmentvariables at build time except by declaring build arguments. Having that
keyword is messy and opens the door to non-hermetic builds, which is
a recipe for leaks and reproducibility problems.
