Container won't start twice: "httpd (pid 13) already running"

[conradkleinespel]

Hello,

Thanks for setting up this image. It's saving me a ton of time 👍

It seems like if you run php:5.6-apache through Docker Compose, it will run fine the first time, but not the second time, because it seems to be keeping a reference to the previous process ID.

This have discussed here previously (in 2014): https://groups.google.com/forum/#!topic/docker-user/2dP09wrq5Qk

Is there any specific reason for this? Would you be OK with a PR that removes the left over PID before exiting, as shown in the link above.

Best regards,
Conrad

I'm running into this issue on the 5.6.3-apache tag.

[tianon]

Can you please try again with 5.6-apache? (5.6.30 is the latest, but intermediate or old point releases are not supported -- only the latest is)

[chrissound]

If they're not supported can we mention this on the readme / docker page?

@chrissound, something other than this?

The description includes a section of "Supported tags" right at the top. 😉

[chrissound]

Oh I see, it's 5.6.30-apache and not 5.6.3-apache, right?

[tianon]

Correct, but "5.6-apache" will track the latest PHP 5.6 release without you having to update at each point release to stay supported (until the EOL of PHP 5.6).
