I would like to create a namespace within a project using the Rancher CLI.

What I already did:

rancher login https://URI --token abcde --context c-abc:p-abc

rancher kubectl create namespace myns --dry-run=client -o yaml | rancher kubectl apply -f -

But the namespace is created in "default" and not in my project.

There are a couple ways I've found to do this:

  1. Create it from a yaml file using kubectl apply -f namespace.yml
apiVersion: v1
kind: Namespace
metadata:
  name: NAME
  annotations:
    field.cattle.io/projectId: PROJECT_NAME:PROJECT_NAMESPACE
  1. If you have the rights to modify a namespace that's not in a project you can add the annotation after you create it
kubectl annotate namespace work-test field.cattle.io/projectId=PROJECT_NAME:PROJECT_NAMESPACE

You can get the project name and namespace by viewing the project yaml file and looking in the metadata section.

  1. View your project's yaml in Rancher and take note of the metadata.name and metadata.namespace fields.

  2. Create your namespace as follows, replacing <name> and <namespace> with the values you noted in step 1:

cat <<EOF | kubectl apply -f -
  apiVersion: v1
  kind: Namespace
  metadata:
    name: myns
    annotations:
      field.cattle.io/projectId: <namespace>:<name>
EOF
