Canary in Coal Mine to find Kubernetes & Jenkins

by EarpMoonWater, posted in aws, docker, Jenkins

Goal:

Our coal mine (CICD pipeline) is struggling, so lets use canary deployments to monitor a Kubernetes cluster under a Jenkins pipeline. Alright, lets level set here…

  • You got a Kubernetes cluster, mmmmkay?
  • A pipeline from Jenkins leads to CICD deployments, yeah?
  • Now we must add the deetz (details) to get canary to deploy

Lessons Learned:

  • Run Deployment in Jenkins
  • Add Canary to Pipeline to run Deployment

Run Deployment in Jenkins:

Source Code:

  • Create fork & update username

Setup Jenkins (Github access token, Docker Hub, & KubeConfig):

Jenkins:

  • Credz
    • Github user name & password (Access token)

Github:

  • Generate access token

DockerHub:

  • DockerHub does not generate access tokens

Kubernetes:

Add Canary to Pipeline to run Deployment:

Create Jenkins Project:

  • Multi-Branch Pipeline
  • Github username
  • Owner & forked repository
    • Provided an option for URL, select deprecated visualization
  • Check it out homie!

Canary Template:

  • We have prod, but need Canary features for stages in our deployment!
  • Pay Attention:
    • track
    • spec
    • selector
    • port

Add Jenkinsfile to Canary Stage:

  • Between Docker Push & DeployToProduction
    • We add CanaryDeployment stage!

Modify Productions Deployment Stage:

EXECUTE!!
