     - In many organizations up to 80% of pipeline execution time is spent in manual build validation steps. How can we reduce that? One option is applying Google's SRE (Site Reliability Engineering) practices by **automating SLI (Service Level Indicators) & SLO (Service Level Objectives) based build validation**. This method has proven to detect problematic issues in production and also allows us to automatically approve or reject builds being pushed through our pipelines.
     - In this session you learn the basics of picking good **SLIs & SLOs** and how to extract them from your monitoring tools. After this session you will be able to start implementing this integration yourself with Jenkins. To give you a jump start you will be introduced to the open source project [Keptn](https://www.keptn.sh) which provides **automated SLI/SLO-based quality gates**. Then we'll talk about [Keptn Jenkins Shared Library](https://github.com/keptn-sandbox/keptn-jenkins-library) which **integrates Jenkins and Keptn** with just a couple of function calls.

With this workflow, there is no need for extra assets, such as a Dockerfile or Kubernetes manifests. You can simply run your code natively on your development workstation while connected to the Kubernetes cluster, allowing you to test your code changes in the context of the larger application.

 ## Templating YAML Files
 - [wikipedia: YAML](https://en.wikipedia.org/wiki/YAML)
+- [redhat.com: YAML for beginners](https://www.redhat.com/sysadmin/yaml-beginners) YAML is an easy, expressive, data-oriented language that distinguishes itself from document markup languages.
 - [thoughtworks.com: Templating in YAML](https://www.thoughtworks.com/radar/techniques/templating-in-yaml) As infrastructures grow in complexity, so do the configuration files that define them. Tools such as [AWS CloudFormation](https://aws.amazon.com/cloudformation/), [Kubernetes](https://www.thoughtworks.com/radar/platforms/kubernetes) and [Helm](https://www.thoughtworks.com/radar/tools/helm) expect configuration files in JSON or YAML syntax, presumably in an attempt to make them easy to write and process. However, in most cases, teams quickly reach the point where they have some parts that are similar but not quite the same, for example, when the same service must be deployed in different regions with a slightly different setup. For such cases tools offer templating in YAML (or JSON), which has caused a huge amount of [frustration with practitioners](https://leebriggs.co.uk/blog/2019/02/07/why-are-we-templating-yaml.html). The problem is that the syntax of JSON and YAML requires all sorts of awkward compromises to graft templating features such as conditionals and loops into the files. **We recommend using an API from a programming language instead or, when this is not an option, a templating system in a programming language, either a general-purpose language such as Python or something specialized such as [Jsonnet](https://jsonnet.org/).**
 - [Steve Horsfield: DevOps tricks - Templating YAML files](https://stevehorsfield.wordpress.com/2019/08/13/devops-tricks-templating-yaml-files/) Basic text tools fall foul of YAML’s indentation sensitivity. On the other hand, **YAML tools like [ytt](https://get-ytt.io/) are pretty difficult to interpret.** In my case, I opted for a small [jq](https://stedolan.github.io/jq/) program executed via [yq](https://mikefarah.gitbook.io/yq/).
