Hello,

I have a problem in the Lab 6. Continuous Deployment with Flux CD --> Sequencing Application Deployments

After doing the actions: **redis-dev **is not pushed to Kubernetes and i have the issues below.

failed to decode Kubernetes YAML from /tmp/kustomization-1240084352/clusters/dev/redis-kustomization.yaml: missing Resource metadata

I checked several times if I had not made a mistake, I did not find any.

try removing the validation flag

Flag --validation has been deprecated, this arg is no longer used, all resources are validated using server-side apply dry-run

flux create kustomization redis-dev \

Hi @adrien6910,

I tried the lab and I didn't get the same issue than you. Perhaps it's because I'm trying with the updated version of the PDF labs, and this lab was updated on June 6.

We are checking on this lab anyway.

Regards,
Luis.

Hi,

After passing the CKA and CKAD certifications. I took the training again and reproduced the same problem, I understood why: it was due to the flux bootstrap github ... command being incomplete due to an incomplete 1st copy-paste. After uninstalling flux then reinstalling and using the complete flux bootstrap github ... command, the problem was solved.

Thank you for your help.
Adrien.

Hi @adrien6910, so it wasn't related to the flux installation, but to copy paste operation.

I'm glad it worked!

Regards,
Luis.

Where can I get the updated version of the pdf files?

Edit: Nevermind, just downloaded again and got the updated version

Hi @vjunior1981 ,

That's good
Just be sure you cleared the cache in the browser.

Please let me know if the lab worked for you.
