commit d63afbf6c59c1565e1c6943747834555852f3bbc Author: Matt Riedemann <mriedem...@gmail.com> Date: Wed Nov 28 16:13:21 2018 -0500 Mention size limit on user data in docs The API reference for the "user_data" parameter to server create and rebuild mentions the size restriction but the user docs did not, so this adds that note. While doing this, several other user-facing docs that mention user data link back to the overall user-data doc so that we can centralize any further documentation about that topic in a single location.

The more you learn about cloud init, the more you like it. Until your cloud init becomes too big to the dislikes of who every design the database schema or API. Then your calls to nova API will fail with: novaclient.exceptions.BadRequest: User data too large. User data must be no larger than 65535 bytes once base64 encoded. Your data is 66080 bytes (HTTP 400) (Request-ID: req-13e1d006-2c77-4ab4-903f- 92f279d64cfc) At this point you invested quite sometime ... and now you have to figure a new strategy.
