Thanks, Darin! I really appreciate the "Best practices" part, especially the sound advise to write more complicated logic on a language that can be tested and call from the command line.

Your Jenkins tutorials are helping me a lot, thank you

🎯 Key Takeaways for quick navigation:

00:41 💻 *Jenkins offers two pipeline syntaxes: declarative and scripted, with declarative providing a better approach for constructing most pipelines since its release in February 2017.*
01:20 🛠️ *Jenkins Pipeline, unlike other job types, allows job definition storage in an SCM, enhancing job management as code.*
03:54 🏗️ *Creating a scripted pipeline involves specifying a "node" block and defining stages, showcasing a simpler 'hello world' example within Jenkins.*
05:15 📄 *Declarative pipelines, although longer in script length, produce the same output as scripted ones, focusing on readability and ease of use.*
06:10 🚦 *Recommended workflow: Begin with declarative syntax; if limitations arise, consider integrating shared libraries before resorting to scripted syntax, known for its complexity.*
07:19 ⚠️ *Jenkins scripted and declarative syntaxes are intended solely for CI purposes. For integrating with other systems, use a real programming language and execute it from Jenkins via command line calls.*

Yet again, a great video. It would good if you can show us the steps reference documentation page and go through the syntax and start using it in a step especially a plugin would be ideal. We are having difficulty in understanding the Jenkins plugin reference on web. How to use it in real time

Could you do a video demonstrating declarative pipeline development, in vscode? Linting tools, extensions, validating, etc… all from my vscode session.

Also, validating my declarative pipeline against my Jenkins instance running on HTTPS with SSO provided by ADFS/Okta

How do you manage release pipeline in Jenkins?

Dear Darin,

I have a question.

Does the name for each stage of the pipeline must be hard-coded?

Can I do something like this?

stage('Print Env ' + varNum) {
echo "$varNum"
}


where varNum can be 1, 2 or 3?

Thanks

I don't see "scripted pipeline in the try sample drop down box at all.

Dont see too much difference between scripted and declarative...
