When inspecting the Health section in the container we can observe:

            "Health": {
                "Status": "unhealthy",
                "FailingStreak": 2877,
                "Log": [

    Fix ironic-pxe healthcheck.

    When the /run_command file is not found on the
    container using the ironic-pxe image, the health
    status displays unhealthy even though it's not
    true. The reason is because grep can't find
    the file and the error makes the whole healthcheck
    fail.
    This patch redirects the error output so the command
    doesn't fail, but the conditional is properly
    evaluated.
