42MB container image with basic PHP 5.6 installation and Composer,
based on AlpineLinux.
If you need to run PHP scripts inside containers,
but don't want the bulk of Ubuntu..
-
make sure to have required dependencies in composer.json
-
run your php scripts as:
docker run -it --rm -v $(pwd):/app anapsix/php --upgrade ./script_name.php
Make your own image based on this one like so (see [./example][https://github.com/anapsix/docker-php/tree/master/example]):
FROM anapsix/php
CMD ["./myscript.php"]
To install additional dependencies for your script/application, you can
place package names (one per line, comments and empty lines are ignored) into
./deps.apk. It will be checked for during the build and packages will be
installed via apk.
To install build-time only dependencies (system libraries, etc),
placepackage names into ./deps_build.apk. They will be removed after
compose install.
For list of available packages see http://pkgs.alpinelinux.org/packages.
For additional convenience, if ./deps.sh exists and is executable, it
will be run after ./deps.apk is processed. This should allow you to install
additional libraries not available in AlpineLinux APK repository or perform
any custom action (i.e. create users, clone a repo, install packages from
pecl/pear, etc).
Similarly to ./deps_build.apk, ./deps_build.sh can be used for custom
build-time pre-composer install steps. It is expected to be executable,
if present. After compose install it will be executed again with --cleanup
argument, which should allow for custom cleanup step.
Build it so:
docker build -t myapp .
and start it thus:
docker run -it --rm myapp
You could (re)build this image locally with:
docker build --no-cache -t anapsix/php https://github.com/anapsix/docker-php.git
