zyratlo opened a new issue, #5255:
URL: https://github.com/apache/texera/issues/5255
### Task Summary
### Task Summary
Introduce the local JupyterLab container that the upcoming
notebook-migration microservice will talk to. This PR is purely infrastructure,
no Texera code paths reference it on `main` yet.
### Scope
Adds three files under `notebook-migration-service/src/main/resources/`:
- `Dockerfile` — builds a Jupyter image from
`jupyter/base-notebook:notebook-6.5.4` and `COPY`s `custom.js` into
`~/.jupyter/custom/custom.js`.
- `docker-compose.yml` — runs JupyterLab as `texera-jupyter` on host port
`9100`, with token/password auth disabled, XSRF check disabled, and a CSP
allowing `frame-ancestors http://localhost:*` so a Texera page can embed it in
an iframe.
- `custom.js` — JupyterLab iframe customization: posts `cellClicked`
events with the cell's UUID to `window.parent`, and listens for
`triggerCellClick` to scroll/highlight target cells.
