Devops

Task

• Write a pipeline that will deploy an "hello world" web app to Kubernetes
• The CI/CD system (where the pipeline resides) and the Kubernetes cluster should be on separate systems
• The web app should be accessible remotely and only with HTTPS

Requirements

• The submission (code/scripts) must be checked into a repository (eg. Github, Gitlab, BitBucket etc.)
• The submission must include clear instructions to run the code/scripts/commands to produce the setup.
• No restriction on the tool/framework/programming language.
• No restriction on use of any of the public clouds - GCP/AWS/Azure.
• No restriction on use of any open source tools or libraries.
• Explain in detail how these libraries/tools work internally. If you are unsure about their internals, it is better to avoid using them and go with a simpler, more understandable approach instead.

Goal

• The assignment is open ended and the point of the exercise is to assess code modularity, usability, extensibility and debuggability.
• Working solution with scope/ideas for improvement and their pros/cons which will be discussed in a follow up meeting.

Tooling

• Teleport
• Cert-manager
• Istio
• Meshery
• Dockerhub
• Terraform-cloud
• GithubAction - CI
• ArgoCD - CD
• Harbor - Push/Pull
• Monitoring - Istio ones
  • Zipkin / Jaeger
  • Grafana
  • Prometheus
  • Kiali
  • Meshery
• Helmfile / helm
• Autoscaler
  • karpenter
• Vault/Console

Steps

1. Bring cluster up in EKS:

cd infrastructure/terraform/environments/production/aws/accounts/aws_prod01/regions/us-east-1/compute/eks
terraform init
terraform plan
terraformapply 

2. Add cluster to kubeconfig:

aws eks update-kubeconfig --name master-UE9fmXo5 --profile AdministratorAccess-645358331312
