Managing resources and objects in your cloud account is an essential aspect of maintaining an efficient and cost-effective infrastructure. Occasionally, you may need to delete specific types of resources and objects to streamline your operations, optimize costs, or meet compliance requirements.

Application start delay in k8s containers

Stress/Load testing applicable. When you want to sping up a lot of pods; the application inside ech pod must start simultaneously with others.
The main problem is cluster autoscaling is slow, it means additional nodes will start with delay.

AWS specific case

The idea here: prescale more nodes than required, so cluster autoscaling will not spend time to spin up new nodes

Assume we have EKS with unmanaged Node Groups as ASG. By updating Minimum capacity > 0 you will achieve, more ‘warm’ nodes that can host extra amount of pods.

In a distributed environment, network retries are an essential mechanism to handle temporary failures in communication between different components. When using Docker containers, network retries can help to ensure the reliability and availability of containerized applications.

Bash script variables and environment variables are both used in Bash scripting, but they have different scopes and lifetimes.
