When deploying microservices applications to a Kubernetes cluster,continuous integration (CI) pipeline includes steps for building Docker images, pushing them to a Docker registry, and updating Kubernetes deployment YAML files with new image tags. The current setup involves Jenkins to automate these tasks. However, this approach presents several challenges:
- Tool Dependency and Setup: Each Jenkins instance requires setup and maintenance of tools like
kubectl
orHelm
for interacting with Kubernetes. - Security Concerns: We need to store and manage Kubernetes and GCP credentials on Jenkins.
- Lack of Deployment Visibility: Post-deployment,Jenkins doesn't actually know the status of that execution did the application actually get created is it in a healthy status or is it actually failing to start.
