LFS268 - Updated course version now live (11.21.2021)

mstepien

Hi,

A new course version of LFS268 went live today.

The updated course is based on Jenkins X version 3.x. All examples and the labs are based on version 3.x. Some of the features of a new version include:

• A helmfile-based approach for deploying the Jenkins X and its dependencies.
• Use of Terraform for Jenkins X installation.
• New improved JX CLI tool.
• UI support.

As many of the old JX commands are deprecated in version 3.x, updated course is redesigned to highlight new capabilities of version 3.x.

To ensure you have access to the latest updates, please clear your cache before accessing the course.

Have a great learning experience!

Dear, instructions from course labs are very poor.
Something went wrong when deploying infraestructure in GC from terraform (maybe version problem).
I can't deploy JenkinsX at all with the GH repos provided. Did you try it?
I have just done the lfs261 course, and the truth is that I am very disappointed in the quality of the LFS268

Sorry to hear about this. Can you please provide details? What lab you were trying and what errors did you see etc.?

Dear, can't deploy Jenkins X at all, I can't even do the first lab with the initial Jenkins X deployment with given instructions. A lot of pods keep in failure state.
Even reviewing the logs the number of errors makes it difficult to debug.

This seems to be related to the following Jenkins X bug:
https://github.com/jenkins-x/jx/issues/8062

The fix should be out soon. Please keep an eye on this page:
https://github.com/jenkins-x-charts/jxboot-helmfile-resources/pull/412

You will have to re-install once the bug is fixed.

Please make sure to delete existing GSM repository on GitHub and create a new one by following step 10 of lab 4.1.

General caveats for failing installations:
1. Make sure your Github token is valid
2. If you have changed it recently, please make sure to delete $HOME/git/credentials file. This will ensure jx will not use old cred.
3. If you are running multiple back to back terraform apply commands, make sure to change the cluster name in values.auto.tfvars file in your jx3-terraform-gke dir. This will make sure GKE doesnot reuse the recently deleted cluster.

Hope this helps.

To avoid the problem caused by Jenkins X bug, we are rolling back to the tested version.

Here is what you need to do to pick the right version of Jenkins X.
1. Delete existing GSM and GKE repositories
2. Generate new repositories from these urls: https://github.com/LFS268/jx3-terraform-gke/generate and https://github.com/LFS268/jx3-gke-gsm/generate
3. Follow step 11 as outlined in Lab 4.1

Please let me know in case of any questions.
