Journey to K8s  

• Auto Scalable K8s configuration (API)
• Application Packaging and templating - Helm
• Serverless Containers - Knative (CAAS) (CMS)
• Gitops Pattern
• Serverless CI/CD - Jenkins-X
• Progressive Delivery - Flagger + Prometheus + Nginx ingress
• Monitoring, Tracing and Alerting - Prometheus + Grafana + Alert manager

Agenda

Kubernetes

• Kubernetesis an open source container orchestration platform that automates many of the manual processes involved in deploying, managing, and scaling containerized applications.

Serverless

• Function as service

• Server is invisible

• Pay as you go

• Run only if you need

Knative

• Container as a service

• Run only if you need

• Self-Serverless

Helm

• Kubernetes-based platform to deploy and manage modern serverless workloads.

   

Serverless CI/CD -JenkinsX

 Each Environment is managed following the GitOps methodology - the desired state of an Environment is maintained in a Git repository and committing or rolling back changes to the repository triggers an associated change of state in the given Environment in Kubernetes.

Gitops

System development and management pattern

• Git is considered to be a Source of Truth for everything, from code to environments setup.
• Any operational changes, including environments config updates, are done via Pull Requests
• Any divergence from Git version triggers conversion mechanism
• In case if rollback is needed or disaster happens, the state of the system can easily be pulled from Git

Progressive Delivery

Progressive delivery is continuous delivery with fine-grained control over the blast radius.

Flagger
