Proposed Changes:

Similarly to #3148, I'm trying to update package strategy in ui

How did you test it?

• pip install /path/to/haystack-repo/ui
• I have verified that Quick Demo can properly run via Docker Compose
• CI..

Notes for the reviewer

It's just a first try. @masci @ZanSara feel free to guide me...

• After moving some directories, there were issues with rest/UI tests.
  I used matrix.folder to run them separately and now these tests are correctly running.

• There are problems with pipeline-yaml test.
  My PR doesn't change the schema, so it is identical to the schema of the main branch.
  But the test fails, as if the schema generated for the test is different from the schema of the main branch.
  @ZanSara any ideas?

[ZanSara]

Looks good! Only one issue to address.

PS: I've seen the schema check passes now. Sorry for the hassle with it, I hope it will be more stable now 😅

[ZanSara]

Just curious here, there was a specific reason to move /ui out of /opt?

[anakin87]

No particular reason.
I tried to clean and simplify the Dockerfile.
If it's not desirable, I can easily revert this change!

[ZanSara]

No no, that's all right 👍 I'll tag @masci just in case but I don't see an issue here.

[masci]

Not a big deal, /opt is just a convention (albeit a very widespread one 😅)

[ZanSara]

Glad this new version is working! Thank you for all the work 😊
