Go is the language of choice for a lot of (cloud-native) projects because it creates very streamlined binaries. We used to “vendor” in all dependencies, but with Go Modules we now have real dependency management. We’ll show you a few pipelines from code to production and see if Modules are that much better to make builds lightning quick and hassle-free.

1. Where did my module go?
Codefresh & JFrog

2. • Who’s a Go dev?
• Who’s using Go modules?
• Who’s here just for the food?
Before we get started

There once was a programmer sage,
Who proclaimed Golang is all the rage,
Use a module or three
And admire the beauty
Of Go in this cloud-native age

4. • Developer Advocate
• Passionate about Serverless,
Containers, and all things
Cloud
• I love dadjokes, cheesecake
and APIs

Why couldn’t the Go programmer pay his taxes?
He only had con-currency…

There once was a DevOps maintainer
Who used to be quite the complainer
But now there’s nothing to fear
Thanks to the Codefresh team here
Everything’s deployed in a container

A brief history of GO

10. Let’s go on a trip through
history
@LeonStigter | @TodayWasAwesome | jfrog.com/shownotes

11. A quick history of go
Go 1.0
First major milestone as a
long term stable release
2012 2015
Go 1.5
First release to no longer
use C (except for cgo)
Support for Vendoring
2017
Go 1.8
Introduction of Go plugins
2018
Go 1.10
Changes to the toolchain,
runtime, and libs

12. Dependency Management…
One thing missing

15. Official Dependency
Management
No more GOPATH In one single tool
So, what are modules?
@LeonStigter | @TodayWasAwesome | jfrog.com/shownotes

16. Vendoring is a really, really bad idea
@LeonStigter | @TodayWasAwesome | jfrog.com/shownotes
But why not use vendoring?

17. Forking is not always good, bad forking is always bad
@LeonStigter | @TodayWasAwesome | jfrog.com/shownotes
And that’s what vendoring is

18. In software Immutable and repeatable are really important
The best way to guarantee issues is force push
Immutable dependencies
Who doesn’t remember left-pad with Node.js?
Lost Dependencies
Do you trust your colleagues? What about the rest of the Internet?
Trust

19. Summarizing the last slide
@LeonStigter | @TodayWasAwesome | jfrog.com/shownotes
Friends don’t let friends do
git push -f
