Projects
Creating a Project
Project resources may only be created on the management cluster. See below for creating namespaces under projects in a managed cluster.
Creating a Basic Project
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: Project
metadata:
generateName: p-
namespace: c-m-abcde
spec:
clusterName: c-m-abcde
displayName: myproject
EOF
Use metadata.generateName
to ensure a unique project ID, but note that kubectl apply
does not work with metadata.generateName
, so kubectl create
must be used instead.
Set metadata.namespace
and spec.clusterName
to the ID for the cluster the project belongs to.
If you create a project through a cluster member account, you must include the annotation, field.cattle.io/creatorId
, and set it to the cluster member account’s user ID.
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: Project
metadata:
annotations:
field.cattle.io/creatorId:
user-id
generateName: p-
namespace: c-m-abcde
spec:
clusterName: c-m-abcde
displayName: myproject
EOF
Setting the field.cattle.io/creatorId
field allows the cluster member account to see project resources with the get
command and view the project in the Rancher UI. Cluster owner and admin accounts don’t need to set this annotation to perform these tasks.
Setting the field.cattle.io/creator-principal-name
annotation to the user’s principal preserves it in a projectroletemplatebinding automatically created for the project owner.
If you don’t want the creator to be added as the owner member (e.g. if the creator is a cluster administrator) to the project you may set the field.cattle.io/no-creator-rbac
annotation to true
, which will prevent the corresponding projectroletemplatebinding from being created.
Creating a Project With a Resource Quota
Refer to Kubernetes Resource Quota.
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: Project
metadata:
generateName: p-
namespace: c-m-abcde
spec:
clusterName: c-m-abcde
displayName: myproject
resourceQuota:
limit:
limitsCpu: 1000m
namespaceDefaultResourceQuota:
limit:
limitsCpu: 50m
EOF
Creating a Project With Container Limit Ranges
Refer to Kubernetes Limit Ranges.
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: Project
metadata:
generateName: p-
namespace: c-m-abcde
spec:
clusterName: c-m-abcde
displayName: myproject
containerDefaultResourceLimit:
limitsCpu: 100m
limitsMemory: 100Mi
requestsCpu: 50m
requestsMemory: 50Mi
EOF
Adding a Member to a Project
Look up the project ID to specify the metadata.namespace
field and projectName
field values.
kubectl --namespace c-m-abcde get projects
Look up the role template ID to specify the roleTemplateName
field value (e.g. project-member
or project-owner
).
kubectl get roletemplates
When adding a user member specify the userPrincipalName
field:
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: ProjectRoleTemplateBinding
metadata:
generateName: prtb-
namespace: p-vwxyz
projectName: c-m-abcde:p-vwxyz
roleTemplateName: project-member
userPrincipalName: keycloak_user://user
EOF
When adding a group member specify the groupPrincipalName
field instead:
kubectl create -f - <<EOF
apiVersion: management.cattle.io/v3
kind: ProjectRoleTemplateBinding
metadata:
generateName: prtb-
namespace: p-vwxyz
projectName: c-m-abcde:p-vwxyz
roleTemplateName: project-member
groupPrincipalName: keycloak_group://group
EOF
Create a projectroletemplatebinding for each role you want to assign to the project member.
Listing Project Members
Look up the project ID:
kubectl --namespace c-m-abcde get projects
to list projectroletemplatebindings in the project’s namespace:
kubectl --namespace p-vwxyz get projectroletemplatebindings
Deleting a Member From a Project
Lookup the projectroletemplatebinding IDs containing the member in the project’s namespace as decribed in the Listing Project Members section.
Delete the projectroletemplatebinding from the project’s namespace:
kubectl --namespace p-vwxyz delete projectroletemplatebindings prtb-qx874 prtb-7zw7s
Creating a Namespace in a Project
The Project resource resides in the management cluster, even if the Project is for a managed cluster. The namespaces under the project reside in the managed cluster.
On the management cluster, look up the project ID for the cluster you are administrating since it generated using metadata.generateName
:
kubectl --namespace c-m-abcde get projects
On the managed cluster, create a namespace with a project annotation:
kubectl apply -f - <<EOF
apiVersion: v1
kind: Namespace
metadata:
name: mynamespace
annotations:
field.cattle.io/projectId: c-m-abcde:p-vwxyz
EOF
Note the format, <cluster ID>:<project ID>
.
Deleting a Project
Look up the project to delete in the cluster namespace:
kubectl --namespace c-m-abcde get projects
Delete the project under the cluster namespace:
kubectl --namespace c-m-abcde delete project p-vwxyz
Note that this command doesn’t delete the namespaces and resources that formerly belonged to the project.
