Dangling images in Docker are unused images that are not associated with any container.
Dangling images can accumulate over time and take up valuable disk space.
They can be removed using the 'docker image prune' command.
An example of a dangling image is an image that was created but not used in any container.
Dangling images can also be created when a container is stopped and a new image is built using the same name.
Use disk cleanup, delete old builds, limit log retention, and use thin backup to save space in Jenkins.
Use disk cleanup to remove unnecessary files and temporary data.
Delete old builds that are no longer needed.
Limit log retention to reduce the amount of space used by logs.
Use thin backup to backup only essential data and save space.
Consider using external storage solutions for larger Jenkins instances.
K8s cluster can be monitored using various tools and techniques.
Use Kubernetes Dashboard to view the status of the cluster and its resources

Auto scaling can be achieved through horizontal scaling and vertical scaling.
Horizontal scaling involves adding more instances of the application to handle the increased traffic.
Vertical scaling involves increasing the resources of the existing instances to handle the increased traffic.
Auto scaling can be achieved through tools like AWS Auto Scaling, Kubernetes Horizontal Pod Autoscaler, etc.
Metrics like CPU utilizatio...
