CI/CD
None
None
None
Container orchestration platform
Deploy, run and scale your services in isolated containers
Your application is bundled in an image
The image contains everything the application needs to run
The image is started in an isolated container
No vendor lock in
Standardized APIs
Your laptop
Bare metal
Cloud Providers
And if you don't want to install and maintain Kubernetes
yourself
Managed Kubernetes
None
So we have code, how do we get this into
Kubernetes?
Angular demo application
Demo
We have to
Build a docker image
Contains everything that the service needs to run
Make the build as fast as possible
Make the image as small as possible
Demo
Tell Kubernetes to
Start containers
In Kubernetes
• A group of 1 or more containers • Same
port space • Within a Pod: communication over localhost • Every container has their own filesystem • Every Pod has it's own IP • All Pods can talk with each other • IPs change all the time Pod
Deployment
LoadBalancer
Everything in Kubernetes is a resource (document) defined in YAML
Demo
Also all those YAML files are not nice
Helm
Also we need
DNS
TLS
Monitoring
CI/CD pipeline
Make use of Kubernetes "magic"
Demo
Magic recap
LoadBalancers
Automatically creates a highly available LoadBalancer with a public IP
address
Ingress controller
The ingress controller (nginx) listens on routing rules in Ingress
Resources and configures itself to route incoming traffic to the correct running and healthy pods
cert-manager
Cert-manager listens on Ingress Resources and if they need TLS,
requests a certificate from LetsEncrypt
external-dns
External-DNS listens on Ingress Resources and creates DNS entries
Sealed Secrets
Secrets are stored encrypted in Git and decrypted inside of
the cluster
Prometheus
Kubernetes and Node metrics are automatically included
Kubernetes and Node alerts are automatically included
Kubernetes and Node dashboards are automatically included
Scraping targets can be automatically discovered
Service Meshes
None
Recommendation: Start playing around with Kubernetes
Alternatives
Flux
None
Knative
Kubernetes-based platform to deploy and manage modern serverless workloads
Tekton CD
CI that runs completely within Kubernetes with Kubernetes Custom Resources
