# RBD Volume Provisioner for Kubernetes 1.5+ `rbd-provisioner` is an out-of-tree dynamic provisioner for Kubernetes 1.5+. You can use it quickly & easily deploy ceph RBD storage that works almost anywhere. It works just like in-tree dynamic provisioner. For more information on how dynamic provisioning works, see [the docs](http://kubernetes.io/docs/user-guide/persistent-volumes/) or [this blog post](http://blog.kubernetes.io/2016/10/dynamic-provisioning-and-storage-in-kubernetes.html). ## Development Compile the provisioner ```console make ``` Make the container image and push to the registry ```console make push ``` ## Test instruction * Start Kubernetes local cluster See https://kubernetes.io/. * Create a Ceph admin secret ```bash ceph auth get client.admin 2>&1 |grep "key = " |awk '{print $3'} |xargs echo -n > /tmp/secret kubectl create secret generic ceph-admin-secret --from-file=/tmp/secret --namespace=kube-system ``` * Create a Ceph pool and a user secret ```bash ceph osd pool create kube 8 8 ceph auth add client.kube mon 'allow r' osd 'allow rwx pool=kube' ceph auth get-key client.kube > /tmp/secret kubectl create secret generic ceph-secret --from-file=/tmp/secret --namespace=kube-system ``` * Start RBD provisioner The following example uses `rbd-provisioner-1` as the identity for the instance and assumes kubeconfig is at `/root/.kube`. The identity should remain the same if the provisioner restarts. If there are multiple provisioners, each should have a different identity. ```bash docker run -ti -v /root/.kube:/kube -v /var/run/kubernetes:/var/run/kubernetes --privileged --net=host quay.io/external_storage/rbd-provisioner /usr/local/bin/rbd-provisioner -master=http://127.0.0.1:8080 -kubeconfig=/kube/config -id=rbd-provisioner-1 ``` Alternatively, deploy it in kubernetes, see [deployment](deploy/README.md). * Create a RBD Storage Class Replace Ceph monitor's IP in [examples/class.yaml](examples/class.yaml) with your own and create storage class: ```bash kubectl create -f examples/class.yaml ``` * Create a claim ```bash kubectl create -f examples/claim.yaml ``` * Create a Pod using the claim ```bash kubectl create -f examples/test-pod.yaml ``` ## Acknowledgements - This provisioner is extracted from [Kubernetes core](https://github.com/kubernetes/kubernetes) with some modifications for this project.
