Install composer in php container?

[mr-feek]

Do we need an additional container just for composer? I have several extensions I am installing in my php container, which should also be installed in the composer container. I personally am going to remove the composer container. What is the main benefit of having a container just for composer?

There are pros and cons of having them in different containers, it's more of a personal choice I guess.

Pros of having different containers:

• Keeps containers lighter
• No build tool mixed with PHP
• Use composer's official image

Cons:

• Composer container cannot check for installed PHP dependencies, so need to use ignore-platform-reqs
• Added complexity

Composer container cannot check for installed PHP dependencies, so need to use ignore-platform-reqs

In my case, this was the (breaking) con. For example, my project requires the bcmath extension to be installed. I rely on composer to ensure that the current environment has that installed.

I was also getting this console output when using the composer container. Maybe it was using composer 2 or something that no longer has the flag? I'm not sure, I didn't dig into it.

The "--ignore-platform-reqs" option does not exist.

The options (as I see them) are to:

• Install all of the same platform dependencies to the composer container as the php container
• Don't use composer for checking/enforcing platform requirements <-- This seems to be the approach that you prefer
• Install composer in the php container <-- This seems to be the approach that I prefer
