How can I enable SOAP client?

I am trying to use the SOAP class using this Docker approach.

How can I install/enable it?

Can you explain a bit more detailed what do you want to do?

If you plan on using the php SoapClient you may need to run a custom build and add this to the docker setup: docker-php-ext-install soap
