Container doesn't start ENTRYPOINT

General

Hello,

I have following specification about the entry point of my apache container:

    {
    "Id": "5bf3de50139df556ffec457b9c113d48e934a5c65596616d91e36f8cd3250459",
    "Created": "2017-06-12T14:39:52.076954844Z",
    "Path": "docker-php-entrypoint",
    "Args": [
        "apachectl",
        "-D",
        "FOREGROUND"
    ],
    "State": {
        "Status": "exited",
        "Running": false,
        "Paused": false,
        "Restarting": false,
        "OOMKilled": false,
        "Dead": false,
        "Pid": 0,
        "ExitCode": 137,
        "Error": "",
        "StartedAt": "2017-06-12T15:13:43.325593139Z",
        "FinishedAt": "2017-06-12T17:16:07.957744355Z"

If I start the container this way:

docker run -d -p 8000:80 --name php7 localhost:5000/7.1.5-apache:latest.1

the container exited immediately, I have to specify always

docker run -d -p 8000:80 --name php7 localhost:5000/7.1.5-apache:latest.1 apachectl -D FOREGROUND

to start Apache. I don’t get in my mind what’s happened here why the entry point seems to be ignored.
