Is there an easy way to recompile php with extra ./configure options.

[WillSkates]

Is there an easy way of adding the option to compile with the --enable-maintainer-zts option or should I create an alternative image for this?

Sorry if i'm being blind and it's already there.

Since this is not the default or upstream recommended option and would affect the users of the image, I think the easiest would be to fork the Dockerfile and build it for your needs.

Same question here, I want to configure with --enable-sockets.

$PHP_EXTRA_CONFIGURE_ARGS appears to be there for exactly this purpose, however I can't get it to work... how can I do it?

Edit/Update: I see now that it is explicitly set within the Dockerfile:

ENV PHP_EXTRA_CONFIGURE_ARGS --with-apxs2

Still cannot modify it from outside though...

Edit/Update 2: Ah, my bad, apparently ENV only works on run, not on build.

@janpapenbrock ENV works during build too, but I suppose it depends on what you're trying to do.

In the case of the sockets module, I believe it can just be added in a derived image with docker-php-ext-install.

See this gist, which uses an example from the PHP sockets documentation (slightly modified to hit www.google.com instead of www.example.com): https://gist.github.com/md5/f0ca3ba1c2b0f04785fb

You can build and test it like so:

$ git clone https://gist.github.com/f0ca3ba1c2b0f04785fb.git php-sockets-test
$ docker build -t php-sockets-test php-sockets-test
$ docker run --rm php-sockets-test

This doesn't work in the case of some modules or for special flags like --enable-maintainer-zts, but it does work for --enable-sockets and most other "normal" modules.

I would swear it didn't work when I tested RUN docker-php-ext-install sockets yesterday (with php:5.6-apache), but today, it works flawlessly.

So thanks for your help! And sorry for hijacking this issue...

FTR, we merged some official ZTS variants in #171. 👍
