An Introduction to Helm - Matt Farina, Samsung SDS & Josh Dolitsky, Blood Orange

CNCF Helm is a package manager that provides the tools to find, share, and install and manage software in Kubernetes. In this session you will learn the basics about using Helm. We will look at the makeup of charts, the packages for Helm. From there we will explore the ways to share and consume charts. To complete the lifecycle, we will look at installing and managing charts in a Kubernetes cluster. Helm is a project that was first introduced in 2015 and was part of Kubernetes prior to the creation of the CNCF. It entered the CNCF as part of Kubernetes and grew to eventually became a sister project, alongside Kubernetes, in the CNCF.

Best part at 9:47: if you enable english subtitles, when it comes to talk about supporting Windows, it gives "We want to support all the developers out there who are engaging with hell"

To say "sadly Deis is not here" is not entirely accurate. Deis was acquired by Microsoft in 2017 who continued to contribute to and promote Helm.

The "why helm" question wasn't answered very well. The justification given was helm replaces 2-4 lines needed to install mysql, but now watch the next 30 minutes to explain how to avoid writing those 2 lines. The helm value proposition is not super clear to me still. For example, 17 minutes in: Helm actually manages the lifecycle of your application. That would be good to explain in the intro "why helm" section.

Is it possible  to stop helm upgrade or how to do immutable  config map using helm with kubernates v1.13

[MatthewWilcoxson]

God, there are so many adverts on YouTube.

[jonathantroncoso]

the entire first 10:00 is completely worthless garbage about how great the repo is maintained.

[guai]

those templates look horrible. wtf guys? another reskinned xml-based programming? we had enough of this in maven. make some sane dsl!

[timmurphy]

Jumps into details without really explaining what's going on or how.

[DuncanCorps]

This presentation is great until Josh, um, basically, um, starts, essentially, um, talking and not, um, explaining, basically, anything.

[aworden]

Wow, what a terrible presentation. Just dive right into the boring and meaningless syntax with no explanation.
