Parameterized Kubernetes manifest files? I'm learning Kubernetes, coming from an AWS/CloudFormation background to set up my company's infrastructure. One of the strengths of CloudFormation is the use a template that can be parameterized for re-used. So I can use the same template to deploy all our microservices in Fargate, giving it the Docker image, version, CPU/memory counts, etc for each microservice.
When using Kubernetes manifest files, is there good way to &quot;templatize&quot; manifest files? I've read  kustomize, but as the title says it's &quot;template-free,&quot; and to use it for all our microservices, I'll need multiple /someapp/... directory trees, which is NOT what I want.
Sure I can use sed but that seems archaic. I can use yq to massage my yaml files, but this also seems archaic. For either approach, changing a manifest file entails changing the corresponding sed and yp commands.
Any suggestions on how to approach this? How about 3rd party tools like Codefresh? How about helm? (I haven't looked at it yet.).
I educated myself more about helm and it looks like it has these features that I need

packaging
templating
release management, including rollbacks

so I'll study it more.
