Deployment of functions is failing on new release of Kubeless 0.3.2 with error "spec.ports: Required value"

[vishweshwarp]

Tried deploying a very basic python function. Looks like this issue is due to newly added custom port support in latest kubeless release (0.3.2)

@vishweshwarp the Service specification definition was moved in the latest release from the controller to the Kubeless CLI (https://github.com/kubeless/kubeless/pull/397). We need to adapt this CLI to mimic that behavior.

[vishweshwarp]

@andresmgot are we going to get a new version of serverless-kubeless plugin to fix this issue?

[ngtuna]

@vishweshwarp Yes we are planning to roll out new version of the plugin. At the meantime, we rolled out kubeless v0.3.3 to fix this issue. So if you can upgrade your kubeless to v0.3.3, the plugin will get back to work well.

[andresmgot]

The code is now adapted to define its own service specification (https://github.com/serverless/serverless-kubeless/pull/101) so this issue should be now fixed. The fix will be available in the next serverless-kubeless release but we recommend you to upgrade Kubeless. @vishweshwarp let us know if you still find any issue.
