Bug 1882113

This assumes that the masakari charms smoke test was run using the openstack provider.

Check that all the segments are online (you may have to install python-masakariclient into your client venv):

` $ openstack segment host list 08b44816-01ce-4470-a047-98114f906a84

gnuoy / Random Tips for Sunbeam development.md
Last active May 1, 2023 05:53

Do and don'ts

  • Any event that relates to the setup of the unit or application invoke the configure_charm method
  • Unit setup should be in configure_unit
  • Application setup should be in configure_application
  • Do not defer events (unless you really have to)
  • When writing a relation handle keep in mind the the handler may be used by other charms to avoid calling back to specific charm methods in the body of the handler. Instead have the charm pass eveything when the handler is initialaised. This is not always possible.

Single node networking

This reference explains how network access to guests is achieved when deploying microstack using local access to the guests (normal for a single node deployment).

If the defaults are chosen sunbeam will have setup an external subnet within OpenStack which will be used to allocate floating IPs.

$ openstack subnet show -c allocation_pools -c cidr external-subnet
