Contour fails to reconcile (step-by-step / management cluster / step 6)

[adamesch]

I hope it's ok I submit something -- I've been following your lab setup guide (it's generally fantastic), and I ran into an issue setting up Contour on the management cluster. I figured out what was going on, but I don't know what actually needs to be changed in the instructions / scripts to resolve what I found.

Running ./scripts/generate-and-apply-contour-yaml.sh $(yq e .management-cluster.name $PARAMS_YAML) results in an infinite loop. Running kubectl describe app contour -n tanzu-system-ingress reveals the following error:

I managed to fix this by 1) editing the values.yaml file (generated/.../contour/contour-data-values.yaml, 2) recreating the contour-data-values secret manually, and 3) re-applying the contour extension. An extra doc separator ended up being the cause of the initial failure (more screenshots below):

This is a copy of the contour-data-values.yaml file that caused the failure:

I removed one of the doc separators, and reran the commands in /scripts/generate-and-apply-contour-yaml.sh

... which worked:

I'm in the process of learning kubernetes / tanzu, so I'm not entirely sure why having an extra doc separator breaks things, but just thought I would let you know (the original file copied from /tkg-extensions/extensions/ingress/contour/vsphere/contour-data-values.yaml.example does not contain the extra separator)

Hi @adamesch , thanks for the feedback!
Just to confirm, a quick question, what system were you using to run the Lab commands? Is it a Linux machine?

@jaimegag - In the environment I'm working in, I'm running the commands from an Ubuntu 18.04 VM

Hi @adamesch . The recent bump in the lab to align with TKG 1.4 and use yq v4.12+ (https://github.com/Tanzu-Solutions-Engineering/tkg-lab#required-clis) should prevent any issue with those yaml separators.
Please let us know if re-testing with the updated versions works better
