@saiskee please run make fmt and commit the changes to unblock CI.

CI is failing with:

--- FAIL: TestGlooRouter_Sync (0.01s)
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x1d01fe0]

Perhaps this should be a separate issue/PR, but this only fixes our non-istio upstreams.

To solve that I think you'd need in your Canary something like upstreamSslConfigSpec

@saiskee this again:

please run make fmt and commit the changes to unblock CI.

@saiskee now the unit tests are failing, can you please run make test before pushing any more changes? Thanks

@saiskee please update the Helm docs to tell people that discovery is no longer required: https://github.com/fluxcd/flagger/blob/main/charts/flagger/README.md

This also needs an update: https://github.com/fluxcd/flagger/blob/main/docs/gitbook/tutorials/gloo-progressive-delivery.md#bootstrap
