On using these images for extension development

[lksnmnn]

Hey Martin,

thank you for providing these images. It's been very helpful so far. I have one issue though:

Since you only create the typo3conf folder for mounting a volume, but not the typo3conf/ext the system complains that the Directory /typo3conf/ext is not writable. My usecase is the following:

1. Run typo3 locally using docker
2. Mount local extension code into typo3conf/ext in order to test it.
3. Install additional extensions (e.g. the extension-builder)

So far I can achieve 1 and 2 OR 1 and 3, but not 1,2 AND 3. Some resources suggest to create the ext folder during image build, but then I would need to fork and change your images.

Do you know if 2 and 3 can be achieved simultaniously?

Cheers, Lukas
