composer.phar download does not work with a local CA signed cert on the internet proxy about cakephp-ex

it sounds like you probably need a custom assemble script that will pass the additional cacerts to the curl call here (https://github.com/sclorg/s2i-php-container/blob/master/7.0/s2i/bin/assemble#L13) and you can provide the additional cert files either in your source repository, or via one of the other input mechanisms:

or you can provide a custom assemble script that just passes -k to curl, but obviously that has security implications.
