How to do multiple deployments with fleet within the same cluster but with different values & namespace?
Basically I'm looking for a workaround to this issue: https://github.com/rancher/fleet/issues/344.

Automation assistants: GitOps tools in comparison
A newer competitor is Fleet, which is developed by Rancher. Its special ability is that it is able to manage not just one, but a fleet of clusters. PipeCD is similarly young and has an even broader focus. Like Fleet, it promises the ability to manage multiple Kubernetes clusters, and it also offers a UI. In addition, it can handle Terraform and some services from the major cloud providers.

API release strategies with API Gateway
Where appropriate, canary releases are an excellent option, as the percentage of traffic exposed to the canary is highly controlled. The trade-off is that the system must have good monitoring in place to be able to quickly identify an issue and roll back if necessary (which can be automated). This guide shows you how to use Apache APISIX and Flagger to quickly implement a canary release solution.

GitOps using Flux and Flagger
What is Flagger? Flagger is a Progressive Delivery tool that automates the release process for applications running on Kubernetes. Under the hood, both tools are built on top of a modular GitOps toolkit. It is the main reason why Flagger compliments Flux.

How to rebalance underutilized nodes with CA without single replica Pod downtime?
I would suggest trying a-b deployment in this case using flagger. It will spin up a new instance and gradually rotate out old ones. Maybe that can be helpful in this weird situation :)

argo-rollouts VS flagger - a user suggested alternative
2 projects | 25 Jan 2022
ArgoRollouts offers Canary and BlueGreen deployment strategies for Kubernetes Pods. It's a drop-in replacement for the v1.Deployment object. Flagger is similar what it offers, extending Kubernetes to support Canary and BlueGreen deployment strategies.
