DS: Define default jupyter notebook port in settings (ie, avoid default 8888)

[bafonso]

Feature: Notebook Editor, Interactive Window, Python Editor cells

Description

It would be great to be able to define the default jupyter notebook port in settings. This is specially useful to keep it clashing from other software - including jupyter notebook - running on the default port 8888. Ideally one could set an alternative default port and then it would increase or randomly find another port.

It should already rollover to the next port? Are you seeing problems where it doesn't?

[bafonso]

@rchiodo When it starts it does go to the next port indeed (I just checked and it goes to 8889). What I'd like to be able is to specify its default port from 8888 to 9999 for example. This would let me freely start things (including docker-based servers) on port 8888 without having to restart vscode.

Ah okay. So it works, but you want to force it to a certain range.

We should probably also include any custom arguments, so the user can:

• Set ip
• Set config
• Set --allow-root

Validated. Checked with the --port setting and the NotebookApp prefix. Both worked.
