ArgoCD will automatically update the Deployemnt if there is any change in the Deployement file Here I used Jenkins to build and push to Docker Hub with GitHub/Git commit ID tag
So, here I used Github Actions to update the Kubernetes Deployment File which is present on argocd brach in this repo with Github/Git Commit Id to the docker image tag Next Argo CD will pull new Docker image from the Docker Hub and deploy to the Kubernetes
Note : I used Jenkins to build and push and Github actions to update commit id to the k8s_deployment_service.yaml (argocd branch) on which is tracked by ArgoCD, if there is any changes to the file ArgoCD will bring our Deployemnt to the Desire state I got issues while updating and pushing k8s_deployment_service.yaml to argocd branch using Jenkins, there are ways to solve it. But I want to experiment with Github Actions, I tried updating k8s_deployment_service.yaml and pusing it to argocd branch
I used rollback on ArgoCD dashboard to get to previous docker image, if there is any issue with newer image
At first I removed the Deplyment App from Argo CD Dashboard Next Removing all resources from Argo CD Namespace - pods, deployments, services Next Removing Argo CD Namespace
If you check kubectl get all -n numeric you can find no resources (here I named deploying namespace as numeric )

We can scan the Severity by making changes to code - we can check the CVE on the google and we need to do the required changes to the code and it should not break the code and result - minor change I did here is the chnaging the Spring boot release version - 2.2.1 -> 2.3.4 - by this there Severity got decreased by a margin
Here I changed failBuildOnCVSS to 11 - to pass build - but the cvss score is based out of 10 as maximum

Setting Context https://humalect.com/blog/kubectl-config-set-context
When to use metric or log data to track a particular piece of telemetry can be summarized with the following points:
Use metrics to track the occurrence of an event, counting of items, the time taken to perform an action or to report the current value of a resource (CPU, memory, etc.)
Use logs to track detailed information about an event also monitored by a metric, particularly errors, warnings or other exceptional situations.
A trace provides visibility into how a request is processed across multiple services in a microservices environment. Every trace needs to have a unique identifier associated with it.
