Jenkins Pipeline Tutorial: Declarative Pipeline vs Scripted Pipeline

Many people ask this question: should I use Jenkins Declarative Pipeline syntax, or should I use the scripted one? And what is the difference between the two? In this video, I will show you what are the most significant differences between those two types of Jenkinsfile syntax. You need to know that the scripted pipeline was the first implementation of the "pipeline as a code" standard in the Jenkins ecosystem. The declarative pipeline represents newer attempt to this standard implementation introducing more opinionated syntax and adding several interesting features you can't find in the scripted pipeline syntax. And last but not least, both variants use Groovy DSL. Let's dive into both and learn what are the most important differences between the two.

I started watching "Cory shaffer's python" tutorials when it had 406 views. Now, after 2 years, i became a python developer and Cory became a gem of YouTube python community. I can see another upcoming teacher in you. Really good video quality, grate explanation.
Suggestion : If you are appearing on screen try to be bit more pleasant. :)

Simple and accertive! I'm starting with Jenkins and haven't found an explanation that helped me like this! Thanks a lot!

[gajapathikrishni]

Really well explained about the differences, my long lasting confusion got cleared now. It helps me a lot.Thanks to Szymon :)

[SumitKarmakar]

Like the way you started. It's casual but elegant.

[bluebobx]

Well done Syzmon, clear and concise - and it's a subject where you absolutely, positively need to see worked examples. Really wish the Jenkins project would link to this video from their declarative/scripted pipeline part in the online docs. And yeah, you sold me on declarative! ;)

[TaianNB]

High quality video and content. Clear as water!
Congrats

[edipocdf]

Best explanation so far, I already know a little thing about declarative and why was better but your video have much better points.

[spaceman]

That was life changing! Thank you! Ps. świetnie mówisz po angielsku :)

[lakshmipasala]

The way you explained is simply superb

[ChristopherCastaneiraMadrigal]

Well, tbh I was hoping nothing after some time looking how to introduce myself into this Jenkinsfile world, but I found everything I didn't know I was looking for, this is one of my favorite sources to learn from… thank you very much @Szymon.

If you know Groovy language, then declarative pipeline makes it powerful to implement complex tasks.
