Agenda

@tektoncd

What is Cloud Native?

● Microservices in containers

● Dynamically orchestrated

● Optimized resource utilization

@tektoncd

● Platform for managing containers

● Tell Kubernetes how to deploy your services and it does it

● Abstracts away the underlying cloud

● Cloud agnostic

@tektoncd

What is CI/CD?Continuous Integration & Delivery

@tektoncd

Cloud Native CI/CDThe good

Containers Reproducible and reusable

Dynamic orchestration Increased reliability

Serverless resource utilization Reduced cost

Conformant APIs Portability

@tektoncd

Cloud Native and CI/CD The challenges

● Same old problems in a different form

○ Images instead of binaries

○ Clusters / many environments

● Some things more challenging

○ Microservices instead of monoliths

● Many deployment targets

● Confusing terminology

Tekton Pipelines:the parts

CRDs

Extending Kubernetes with custom types

Controllers act on Resources

= CI/CD platform on Kubernetes

@tektoncd

Custom Resource DefinitionsHey kubernetes! Please create this cat for me.

Sorry, I only speak yaml.

Ah right. kubectl create -f mycat.yaml

Hmm, I don't know about the type "Cat".

Cat's have paws, they're fluffy, they have claws...

Now we're talking. Ah, that's what a "Cat" is.

Here's my cat: kubectl create -f mycat.yaml

YAML!

Ahhh! kubectl create -f cat-definition.yaml

OK, I'll keep that over here next to the Pods and Services.

@tektoncd

Custom Resource ControllersHey kubernetes! Do you have any cats?

Nope, no cats.

Hey kubernetes! How about now?

Nope, still none.

How about now?

OK, just got a cat, it's here:

Thanks, I'll do some cat stuff with it.

Dude… This is Kubernetes. I'll tell you when I get one.

OK, thanks!

You do you.

@tektoncd

CRD StandardsHey kubernetes! Do you have any cats?

Sure, I have k8s.io/cat, whizzbang.com/cat, mypets.info/cat, foobar.com/cat, google.com/cat,...

Whoa, what's the difference?

k8s.io/cat has paws and fur, whizzbang.com/cat has a tail and color,...

Can I have them all?

No, they don't get along with each other

EXPLOSION

@tektoncd

Step

● Kubernetes container spec

● Container image with all the info you need to run it

- name: run-ko image: gcr.io/tekton-releases/ko-ci env: - name: KO_DOCKER_REPO value: gcr.io/my-registry - name: GOPATH value: /workspace/go command: - /bin/sh args: - -c - ko resolve -f my-src > release.yam volumeMounts: - name: gcp-secret mountPath: /secret

@tektoncd

Task CRD

● New CRD

● Sequence of steps

● Run in sequential order

● Run on the same k8s node

@tektoncd

Pipeline CRD

● Express Tasks order

○ Sequentially

○ Concurrently

○ (Graph)

● Execute Tasks on different nodes

● Typed inputs and outputs

@tektoncd

Tekton Pipelines: example

@tektoncd

Runtime CRDs

● Instances of Pipeline/Task:

○ PipelineRun

○ TaskRun

○ PipelineResource

● Runtime info like image registry,git repo, etc.

compliance● Tekton

○ Shared Catalog!○ More features in Pipelines:

■ Event triggering■ Conditional execution■ PullRequest/SCM support■ And more!

○ More projects, with Pipelines at the core!
