Hey, I'm trying to deploy a basic app using raw manifests and fleet. One manifest is the namespace and the other one is my deployment. Is there a way to tell fleet to create the namespace first ? Is it a bad idea to manage the namespace with fleet ?

you could combine both manifests into one with namespace at the top.

Thanks for your answer. I guess it works for my example but what if my app is more complex, like a custom configmap per environment, in different overlays/env folders ? I can't combine all manifest into one yaml file

then you need to use the

dependsOn

functionality in the fleet.yaml

👍 1

# dependsOn allows you to configure dependencies to other bundles. The current bundle
# will only be deployed, after all dependencies are deployed and in a Ready state.
dependsOn:
  # Format: <GITREPO-NAME>-<BUNDLE_PATH> with all path separators replaced by "-"
  # Example: GitRepo name "one", Bundle path "/multi-cluster/hello-world" => "one-multi-cluster-hello-world"
  - name: one-multi-cluster-hello-world
  # Select bundles to depend on based on their label.
  - selector:
      matchLabels:
        app: weak-monkey

thats how you can get different bundles to be applied in a specific order

I managed to split my app into two bundles so I can create the namespace first but I'm facing this issue: https://github.com/rancher/fleet/issues/1484. My second bundle is a helm chart and the namespace requires PSA annotations

can you add the annotations to the namespace manifest?

I can but the second bundle tries to create the namespace while deploying the helm chart and fails as some annotations on the namespace are referring to the first bundle

doh

yeah that might need an RFE

hrmm

what about an overlay that patches the namespace?

# If using raw YAML these are names that map to overlays/{name} that will be used
  # to replace or patch a resource. If you wish to customize the file ./subdir/resource.yaml
  # then a file ./overlays/myoverlay/subdir/resource.yaml will replace the base file.
  # A file named ./overlays/myoverlay/subdir/resource_patch.yaml will patch the base file.
  # A patch can in JSON Patch or JSON Merge format or a strategic merge patch for builtin
  # Kubernetes types. Refer to "Raw YAML Resource Customization" below for more information.
  yaml:
    overlays:
    - custom2
    - custom3

so namespace.yaml and namespace_patch.yaml in the overlay that has the annotations it needs.

i'm gonna try but I think the main issue is "When we install apps via fleet using the helm install way - this automatically creates the namespace for it" (From the issue linked above) and there is no way to disable or customize the namespace.
