First, we must label our nodes according to their role. Although we are labeling `all` nodes, you are free to label only the nodes you wish. You must have at least one, although a minimum of three are recommended. Nodes are labeled according to their Openstack roles:

## Obtaining the Project
Download the latest copy of Openstack-Helm:
```
admin@kubenode01:~$ git clone https://github.com/att-comdev/openstack-helm.git
admin@kubenode01:~$ cd openstack-helm
git clone https://github.com/att-comdev/openstack-helm.git
cd openstack-helm
```
## Ceph Preparation and Installation
Ceph must be aware of the OSX cluster and public networks. These CIDR ranges are the exact same ranges you used earlier in your Calico deployment yaml (our example was 10.25.0.0/16 due to our 192.168.0.0/16 overlap). Explore this variable to your deployment environment by issuing the following commands:
```
admin@kubenode01:~$ export osd_cluster_network=10.25.0.0/16
admin@kubenode01:~$ export osd_public_network=10.25.0.0/16
export osd_cluster_network=10.25.0.0/16
export osd_public_network=10.25.0.0/16
```
## Ceph Storage Volumes
Ceph must also have volumes to mount on each host labeled for `ceph-storage`. On each host that you labeled, create the following directory (can be overriden):
```
admin@kubenode01:~$ mkdir -p /var/lib/openstack-helm/ceph
mkdir -p /var/lib/openstack-helm/ceph
```
*Repeat this step for each node labeled: `ceph-storage`*
## Ceph Secrets Generation
Although you can bring your own secrets, we have conveniently created a secret generation tool for you (for greenfield deployments). You can create secrets for your project by issuing the following:
```
admin@kubenode01:~$ cd helm-toolkit/utils/secret-generator
admin@kubenode01:~$ ./generate_secrets.sh all `./generate_secrets.sh fsid`
admin@kubenode01:~$ cd ../../..
cd helm-toolkit/utils/secret-generator
./generate_secrets.sh all `./generate_secrets.sh fsid`
cd ../../..
```
## Nova Compute Instance Storage
Nova Compute requires a place to store instances locally. Each node labeled `openstack-compute-node` needs to have the following directory:
```
admin@kubenode01:~$ mkdir -p /var/lib/nova/instances
mkdir -p /var/lib/nova/instances
```
*Repeat this step for each node labeled: `openstack-compute-node`*
## Helm Preparation
Now we need to install and prepare Helm, the core of our project. Please use the installation guide from the [Kubernetes/Helm](https://github.com/kubernetes/helm/blob/master/docs/install.md#from-the-binary-releases) repository. Please take note of our required versions above.
Once installed, and initiated (`helm init`), you will need your local environment to serve helm charts for use. You can do this by:
```
admin@kubenode01:~$ helm serve . &
admin@kubenode01:~$ helm repo add local http://localhost:8879/charts
helm serve &
helm repo add local http://localhost:8879/charts
```
# Openstack-Helm Installation
Now we are ready to deploy, and verify our Openstack-Helm installation. The first required is to build out the deployment secrets, lint and package each of the charts for the project. Do this my running `make` in the `openstack-helm` directory:
```
admin@kubenode01:~$ make
make
```
**Helpful Note:** If you need to make any changes to the deployment, you may run `make` again, delete your helm-deployed chart, and redeploy the chart (update). If you need to delete a chart for any reason, do the following:
```
admin@kubenode01:~$ helm list

At this time (and before verification of Ceph) you'll need to install the `bootstrap` chart. The `bootstrap` chart will install secrets for both the `ceph` and `openstack` namespaces for the general StorageClass:
```
admin@kubenode01:~$ helm install --name=bootstrap-ceph local/bootstrap --namespace=ceph
admin@kubenode01:~$ helm install --name=bootstrap-openstack local/bootstrap --namespace=openstack
helm install --name=bootstrap-ceph local/bootstrap --namespace=ceph
helm install --name=bootstrap-openstack local/bootstrap --namespace=openstack
```
You may want to validate that Ceph is deployed successfully. Here are a couple of recommendations for this.
You may want to validate that Ceph is deployed successfully. For more information on this, please see the section entitled [Ceph Troubleshooting](../troubleshooting/ts-persistent-storage.md).
### Ceph Validating PVC
To validate persistent volume claim (PVC) creation, we've placed a test manifest in the `./test/` directory. Deploy this pvc and explore the deployment:
```
admin@kubenode01:~$ kubectl get pvc -o wide --all-namespaces -w
NAMESPACE NAME STATUS VOLUME CAPACITY ACCESSMODES AGE
ceph pvc-test Bound pvc-bc768dea-c93e-11e6-817f-001fc69c26d1 1Gi RWO 9h
admin@kubenode01:~$
```
The output above indicates that the PVC is 'bound' correctly. Now digging deeper:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl describe pvc pvc-test -n ceph
Name: pvc-test
Namespace: ceph
StorageClass: general
Status: Bound
Volume: pvc-bc768dea-c93e-11e6-817f-001fc69c26d1
Labels: <none>
Capacity: 1Gi
Access Modes: RWO
No events.
admin@kubenode01:~/projects/openstack-helm$
```
We can see that we have a VolumeID, and the 'capacity' is 1GB. It is a 'general' storage class. It is just a simple test. You can safely delete this test by issuing the following:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl delete pvc pvc-test -n ceph
persistentvolumeclaim "pvc-test" deleted
admin@kubenode01:~/projects/openstack-helm$
```
### Ceph Validating StorageClass
Next we can look at the storage class, to make sure that it was created correctly:
```
admin@kubenode01:~$ kubectl describe storageclass/general
Name: general
IsDefaultClass: No
Annotations: <none>
Provisioner: kubernetes.io/rbd
Parameters: adminId=admin,adminSecretName=pvc-ceph-conf-combined-storageclass,adminSecretNamespace=ceph,monitors=ceph-mon.ceph:6789,pool=rbd,userId=admin,userSecretName=pvc-ceph-client-key
No events.
admin@kubenode01:~$
```
The parameters is what we're looking for here. If we see parameters passed to the StorageClass correctly, we will see the `ceph-mon.ceph:6789` hostname/port, things like `userid`, and appropriate secrets used for volume claims. This all looks great, and it time to Ceph itself.
### Ceph Validation
Most commonly, we want to validate that Ceph is working correctly. This can be done with the following ceph command:
```
admin@kubenode01:~$ kubectl exec -t -i ceph-mon-0 -n ceph -- ceph status
cluster 046de582-f8ee-4352-9ed4-19de673deba0
health HEALTH_OK
monmap e3: 3 mons at {ceph-mon-392438295-6q04c=10.25.65.131:6789/0,ceph-mon-392438295-ksrb2=10.25.49.196:6789/0,ceph-mon-392438295-l0pzj=10.25.79.193:6789/0}
election epoch 6, quorum 0,1,2 ceph-mon-392438295-ksrb2,ceph-mon-392438295-6q04c,ceph-mon-392438295-l0pzj
fsmap e5: 1/1/1 up {0=mds-ceph-mds-2810413505-gtjgv=up:active}
osdmap e23: 5 osds: 5 up, 5 in
flags sortbitwise
pgmap v22012: 80 pgs, 3 pools, 12712 MB data, 3314 objects
101 GB used, 1973 GB / 2186 GB avail
80 active+clean
admin@kubenode01:~$
```
Use one of your Ceph Monitors to check the status of the cluster. A couple of things to note above; our health is 'HEALTH_OK', we have 3 mons, we've established a quorum, and we can see that our active mds is 'ceph-mds-2810413505-gtjgv'. We have a healthy environment.
For Glance and Cinder to operate, you will need to create some storage pools for these systems. Additionally, Nova can be configured to use a pool as well, but this is off by default.
```
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create volumes 128
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create images 128
```
Nova storage would be added like this:
```
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create vms 128
```
The choosing the amount of storage is up to you and can be changed by replacing the 128 to meet your needs.
We are now ready to install our next chart, MariaDB.
## MariaDB Installation and Verification
We are using Galera to cluster MariaDB and establish a quorum. To install the MariaDB, issue the following command:
```
admin@kubenode01:~$ helm install --name=mariadb local/mariadb --namespace=openstack
helm install --name=mariadb local/mariadb --namespace=openstack
```
MariaDB is a StatefulSet (PetSets have been retired in Kubernetes v1.5.0). As such, it initiates a 'seed' which is used to deploy MariaDB members via [affinity/anti-affinity](http://kubernetes.io/docs/user-guide/node-selection/) features. Ceph uses this as well. So what you will notice is the following behavior:
```
openstack mariadb-0 0/1 Running 0 28s 10.25.49.199 kubenode05
openstack mariadb-seed-0ckf4 1/1 Running 0 48s 10.25.162.197 kubenode01
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE
openstack mariadb-0 1/1 Running 0 1m 10.25.49.199 kubenode05
openstack mariadb-1 0/1 Pending 0 0s <none>
openstack mariadb-1 0/1 Pending 0 0s <none> kubenode04
openstack mariadb-1 0/1 ContainerCreating 0 0s <none> kubenode04
openstack mariadb-1 0/1 Running 0 3s 10.25.178.74 kubenode04
```
What you're seeing is the output of `kubectl get pods -o wide --all-namespaces`, which is used to monitor the seed host preparing each of the MariaDB/Galera members in order: mariadb-0, then mariadb-1, then mariadb-2. This process can take up to a few minutes, so be patient.
To test MariaDB, do the following:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl exec mariadb-0 -it -n openstack -- mysql -h mariadb.openstack -uroot -ppassword -e 'show databases;'
+--------------------+
| Database |
+--------------------+
| information_schema |
| keystone |
| mysql |
| performance_schema |
+--------------------+
admin@kubenode01:~/projects/openstack-helm$
```
Now you can see that MariaDB is loaded, with databases intact! If you're at this point, the rest of the installation is easy. You can run the following to check on Galera:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl describe po/mariadb-0 -n openstack
Name: mariadb-0
Namespace: openstack
Node: kubenode05/192.168.3.25

```
So you can see that galera is enabled.

MariaDB is a `StatefulSet` (`PetSets` have been retired in Kubernetes v1.5.0).

# Diagnosing the problem
# Ceph
**CHART:** openstack-helm/ceph
### Ceph Validating PVC
To validate persistent volume claim (PVC) creation, we've placed a test manifest in the `./test/` directory. Deploy this pvc and explore the deployment:
```
admin@kubenode01:~$ kubectl get pvc -o wide --all-namespaces -w
NAMESPACE NAME STATUS VOLUME CAPACITY ACCESSMODES AGE
ceph pvc-test Bound pvc-bc768dea-c93e-11e6-817f-001fc69c26d1 1Gi RWO 9h
admin@kubenode01:~$
```
The output above indicates that the PVC is 'bound' correctly. Now digging deeper:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl describe pvc pvc-test -n ceph
Name: pvc-test
Namespace: ceph
StorageClass: general
Status: Bound
Volume: pvc-bc768dea-c93e-11e6-817f-001fc69c26d1
Labels: <none>
Capacity: 1Gi
Access Modes: RWO
No events.
admin@kubenode01:~/projects/openstack-helm$
```
We can see that we have a VolumeID, and the 'capacity' is 1GB. It is a 'general' storage class. It is just a simple test. You can safely delete this test by issuing the following:
```
admin@kubenode01:~/projects/openstack-helm$ kubectl delete pvc pvc-test -n ceph
persistentvolumeclaim "pvc-test" deleted

Next we can look at the storage class, to make sure that it was created correctly:
```
