Manage KubeDB managed Kafka objects using CLIs
KubeDB CLI
KubeDB comes with its own cli. It is called kubedb
cli. kubedb
can be used to manage any KubeDB object. kubedb
cli also performs various validations to improve ux. To install KubeDB cli on your workstation, follow the steps here.
How to Create objects
kubectl create
creates a database CRD object in default
namespace by default. Following command will create a Kafka object as specified in kafka.yaml
.
$ kubectl create -f druid-quickstart.yaml
kafka.kubedb.com/kafka created
You can provide namespace as a flag --namespace
. Provided namespace should match with namespace specified in input file.
$ kubectl create -f druid-quickstart.yaml --namespace=kube-system
kafka.kubedb.com/kafka created
kubectl create
command also considers stdin
as input.
cat druid-quickstart.yaml | kubectl create -f -
How to List Objects
kubectl get
command allows users to list or find any KubeDB object. To list all Kafka objects in default
namespace, run the following command:
$ kubectl get kafka
NAME TYPE VERSION STATUS AGE
kafka kubedb.com/v1alpha2 3.6.1 Ready 36m
You can also use short-form (kf
) for kafka CR.
$ kubectl get kf
NAME TYPE VERSION STATUS AGE
kafka kubedb.com/v1alpha2 3.6.1 Ready 36m
To get YAML of an object, use --output=yaml
or -oyaml
flag. Use -n
flag for referring namespace.
$ kubectl get kf kafka -n demo -oyaml

kubectl describe
command provides following basic information about a database.
- StatefulSet
- Storage (Persistent Volume)
- Service
- Secret (If available)
- Topology (If available)
- Monitoring system (If available)
To hide details about StatefulSet & Service, use flag --show-workload=false
To hide details about Secret, use flag --show-secret=false
To hide events on KubeDB object, use flag --show-events=false
To describe all Kafka objects in default
namespace, use following command
$ kubectl describe kf
To describe all Kafka objects from every namespace, provide --all-namespaces
flag.
$ kubectl describe kf --all-namespaces
You can also describe KubeDb objects with matching labels. The following command will describe all Kafka objects with specified labels from every namespace.
$ kubectl describe kf --all-namespaces --selector='app.kubernetes.io/component=database'
To learn about various options of describe
command, please visit here.
Edit restrictions
Various fields of a KubeDb object can’t be edited using edit
command. The following fields are restricted from updates for all KubeDB objects:
- apiVersion
- kind
- metadata.name
- metadata.namespace
- status
If StatefulSets or Deployments exists for a database, following fields can’t be modified as well.
Kafka:
- spec.init
- spec.storageType
- spec.storage
- spec.podTemplate.spec.nodeSelector
- spec.podTemplate.spec.env
How to Delete Objects
kubectl delete
command will delete an object in default
namespace by default unless namespace is provided. The following command will delete a Kafka instance kafka
in demo namespace
$ kubectl delete kf kafka -n demo
kafka.kubedb.com "kafka" deleted
You can also use YAML files to delete objects. The following command will delete an Kafka using the type and name specified in kafka.yaml
.
$ kubectl delete -f druid-quickstart.yaml
kafka.kubedb.com "kafka" deleted
kubectl delete
command also takes input from stdin
.
cat druid-quickstart.yaml | kubectl delete -f -
To delete database with matching labels, use --selector
flag. The following command will delete kafka with label app.kubernetes.io/instance=kafka
.
$ kubectl delete kf -l app.kubernetes.io/instance=kafka
Using Kubectl
You can use Kubectl with KubeDB objects like any other CRDs. Below are some common examples of using Kubectl with KubeDB objects.
# List objects
$ kubectl get kafka
$ kubectl get kafka.kubedb.com
# Delete objects
$ kubectl delete kafka <name>
