Answers: <p>Still the most proper way is to update tags of your docker image and update <code>yourapp.yaml</code> script , there's no other way and then just <code>kubectl -f yourapp.yaml</code>. For this purpose GitOps is used. For me who has small cluster using something as ArgoCD is too much. I've went with Gitlab free service called AutoDevops which deploys read and tested docker container straight to your EKS.</p>

Comments: [ Container team member here ] I am not posting this as an answer because I am not a "running this" but I observe mixed patterns among people: those that want to use a GitOps style use Flux/Flux2 (or Argo) to do this (e.g. they configure Flux to monitor for image tag changes". Those that use traditional CD use whatever tools/mechanism the CI/CD platform offers (e.g. [this](https://shadow-soft.com/jenkins-pipeline-containerized-applications-kubernetes/) is an example of many)

Comments: Our approach - store image metadata on Reliza Hub, then Reliza Hub serves as a database which has information about approved images per each environment. Then you are able to query it with whatever tooling you choose and pull right image to the right environment.
