# Overview
|
||
In order to drive towards a production-ready Openstack solution, our goal is to provide containerized, yet stable [persistent volumes](http://kubernetes.io/docs/user-guide/persistent-volumes/) that Kubernetes can use to schedule applications that require state, such as MariaDB (Galera). Although we assume that the project should provide a “batteries included” approach towards persistent storage, we want to allow operators to define their own solution as well. Examples of this work will be documented in another section, however evidence of this is found throughout the project. If you have any questions or comments, please create an [issue](https://github.com/att-comdev/openstack-helm/issues).
|
||
|
||
**IMPORTANT**: Please see the latest published information about our application versions.

The installation procedures below, will take an administrator from a new `kubeadm` installation to Openstack-Helm deployment.
|
||
|
||
# Kubernetes Preparation
|
||
This walkthrough will help you set up a bare metal environment with 5 nodes, using `kubeadm` on Ubuntu 16.04. The assumption is that you have a working `kubeadm` environment and that your environment is at a working state, ***prior*** to deploying a CNI-SDN. This deployment procedure is opinionated *only to standardize the deployment process for users and developers*, and to limit questions to a known working deployment. Instructions will expand as the project becomes more mature.
|
||
|
||
If you’re environment looks like this, you are ready to continue:
|
||
```
|
||
admin@kubenode01:~$ kubectl get pods -o wide --all-namespaces

```
|
||
|
||
## Deploying a CNI-Enabled SDN (Calico)
|
||
|
||
After an initial `kubeadmn` deployment has been scheduled, it is time to deploy a CNI-enabled SDN. We have selected **Calico**, but have also confirmed that this works for Weave, and Romana. For Calico version v2.0, you can apply the provided [Kubeadm Hosted Install](http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/) manifest:
|
||
|
||
```
|
||
admin@kubenode01:~$ kubectl apply -f http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml
|
||
```
|
||
**PLEASE NOTE:** If you are using a 192.168.0.0/16 CIDR for your Kubernetes hosts, you will need to modify [line 42](https://gist.github.com/v1k0d3n/a152b1f5b8db5a8ae9c8c7da575a9694#file-calico-kubeadm-hosted-yml-L42) for the `cidr` declaration within the `ippool`. This must be a `/16` range or more, as the `kube-controller` will hand out `/24` ranges to each node. We have included a sample comparison of the changes [here](http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml) and [here](https://gist.githubusercontent.com/v1k0d3n/a152b1f5b8db5a8ae9c8c7da575a9694/raw/c950eef1123a7dcc4b0dedca1a202e0c06248e9e/calico-kubeadm-hosted.yml).
|
||
|
||
After the container CNI-SDN is deployed, Calico has a tool you can use to verify your deployment. You can download this tool, [`calicoctl`](https://github.com/projectcalico/calicoctl/releases) to execute the following command:
|
||
```
|
||
admin@kubenode01:~$ sudo calicoctl node status
|
||
Calico process is running.
|
||
|
||

|
||
+--------------+-------------------+-------+----------+-------------+
|
||
| PEER ADDRESS | PEER TYPE | STATE | SINCE | INFO |

|
||
No IPv6 peers found.
|
||
|
||
admin@kubenode01:~$
|
||
```
|
||
|
||
It is important to call out that the Self Hosted Calico manifest for v2.0 (above) supports `nodetonode` mesh, and `nat-outgoing` by default. This is a change from version 1.6.
|
||
|
||
## Preparing Persistent Storage
|
||
Persistent storage is improving. Please check our current and/or resolved [issues](https://github.com/att-comdev/openstack-helm/issues?utf8=✓&q=ceph) to find out how we're working with the community to improve persistent storage for our project. For now, a few preparations need to be completed.
|
||
|
||
### Installing Ceph Host Requirements
|
||
At some future point, we want to ensure that our solution is cloud-native, allowing installation on any host system without a package manager and only a container runtime (i.e. CoreOS). Until this happens, we will need to ensure that `ceph-common` is installed on each of our hosts. Using our Ubuntu example:
|
||
|
||
```
|
||
admin@kubenode01:~$ sudo apt-get install ceph-common -y
|
||
```
|
||
|
||
We will always attempt to keep host-specific requirements to a minimum, and we are working with the Ceph team (Sébastien Han) to quickly address this Ceph requirement.
|
||
|
||
### Ceph Secrets Generation
|
||
|
||
Another thing of interest is that our deployment assumes that you can generate secrets at the time of the container deployment. We require the [`sigil`](https://github.com/gliderlabs/sigil/releases/download/v0.4.0/sigil_0.4.0_Linux_x86_64.tgz) binary on your deployment host in order to perform this action.
|
||
```
|
||
admin@kubenode01:~$ curl -L https://github.com/gliderlabs/sigil/releases/download/v0.4.0/sigil_0.4.0_Linux_x86_64.tgz | tar -zxC /usr/local/bin
|
||
```
|
||
|
||
### Kubernetes Controller Manager
|
||
|
||
Before deploying Ceph, you will need to re-deploy a custom Kubernetes Controller with the necessary [RDB](http://docs.ceph.com/docs/jewel/rbd/rbd/) utilities. For your convenience, we are maintaining this along with the Openstack-Helm project. If you would like to check the current [tags](https://quay.io/repository/attcomdev/kube-controller-manager?tab=tags) or the [security](https://quay.io/repository/attcomdev/kube-controller-manager/image/eedc2bf21cca5647a26e348ee3427917da8b17c25ead38e832e1ed7c2ef1b1fd?tab=vulnerabilities) of these pre-built containers, you may view them at [our public Quay container registry](https://quay.io/repository/attcomdev/kube-controller-manager?tab=tags). If you would prefer to build this container yourself, or add any additional packages, you are free to use our GitHub [dockerfiles](https://github.com/att-comdev/dockerfiles/tree/master/kube-controller-manager) repository to do so.
|
||
|
||
To make these changes, export your Kubernetes version, and edit the `image` line of your `kube-controller-manager` json manifest on your Kubernetes Master:
|
||
```
|
||
admin@kubenode01:~$ export kube_version=v1.5.1
|
||
admin@kubenode01:~$ sed -i "s|gcr.io/google_containers/kube-controller-manager-amd64:'$kube_version'|quay.io/attcomdev/kube-controller-manager:'$kube_version'|g" /etc/kubernetes/manifests/kube-controller-manager.json
|
||
```
|
||
|
||
Now you will want to `restart` your Kubernetes master server to continue.
|
||
|
||
### Kube Controller Manager DNS Resolution
|
||
|
||
Until the following [Kubernetes Pull Request](https://github.com/kubernetes/kubernetes/issues/17406) is merged, you will need to allow the Kubernetes Controller to use the internal container `skydns` endpoint as a DNS server, and add the Kubernetes search suffix into the controller's resolv.conf. As of now, the Kubernetes controller only mirrors the host's `resolv.conf`. This is not sufficient if you want the controller to know how to correctly resolve container service endpoints (in the case of DaemonSets).
|
||
|
||
First, find out what the IP Address of your `kube-dns` deployment is:
|
||
```
|
||
admin@kubenode01:~$ kubectl get svc kube-dns --namespace=kube-system
|
||
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
||
kube-dns 10.96.0.10 <none> 53/UDP,53/TCP 1d
|
||
admin@kubenode01:~$
|
||
```
|
||
|
||
As you can see by this example, `10.96.0.10` is the `CLUSTER-IP`IP. Now, have a look at the current `kube-controller-manager-kubenode01` `/etc/resolv.conf`:
|
||
```
|
||
admin@kubenode01:~$ kubectl exec kube-controller-manager-kubenode01 -n kube-system -- cat /etc/resolv.conf
|
||
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
|
||
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
|
||
nameserver 192.168.1.70
|
||
nameserver 8.8.8.8
|
||
search jinkit.com
|
||
admin@kubenode01:~$
|
||
```
|
||
|
||
What we need is for `kube-controller-manager-kubenode01` `/etc/resolv.conf` to look like this:
|
||
```
|
||
admin@kubenode01:~$ kubectl exec kube-controller-manager-kubenode01 -n kube-system -- cat /etc/resolv.conf
|
||
nameserver 10.96.0.10
|
||
nameserver 192.168.1.70
|
||
nameserver 8.8.8.8
|
||
search svc.cluster.local jinkit.com
|
||
admin@kubenode01:~$
|
||
```
|
||
|
||
You can change this by doing the following:
|
||
```
|
||
admin@kubenode01:~$ kubectl exec kube-controller-manager-kubenode01 -it -n kube-system -- /bin/bash
|
||
root@kubenode01:/# cat <<EOF > /etc/resolv.conf
|
||
nameserver 10.96.0.10
|
||
nameserver 192.168.1.70
|
||
nameserver 8.8.8.8
|
||
search svc.cluster.local jinkit.com
|
||
EOF
|
||
root@kubenode01:/#
|
||
```
|
||
|
||
Now you can test your changes by deploying a service to your cluster, and resolving this from the controller. As an example, lets deploy something useful, like [Kubernetes dashboard](https://github.com/kubernetes/dashboard):
|
||
```
|
||
admin@kubenode01:~$ kubectl create -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml
|
||
```
|
||
|
||
Note the `IP` field:
|
||
```
|
||
admin@kubenode01:~$ kubectl describe svc kubernetes-dashboard -n kube-system
|
||
Name: kubernetes-dashboard
|
||
Namespace: kube-system
|
||
Labels: app=kubernetes-dashboard
|
||
Selector: app=kubernetes-dashboard
|
||
Type: NodePort
|
||
IP: 10.110.207.144
|
||
Port: <unset> 80/TCP
|
||
NodePort: <unset> 32739/TCP
|
||
Endpoints: 10.25.178.65:9090
|
||
Session Affinity: None
|
||
No events.
|
||
admin@kubenode01:~$
|
||
```
|
||
|
||
Now you should be able to resolve the host `kubernetes-dashboard.kube-system.svc.cluster.local`:
|
||
```
|
||
admin@kubenode01:~$ kubectl exec kube-controller-manager-kubenode01 -it -n kube-system -- ping kubernetes-dashboard.kube-system.svc.cluster.local
|
||
PING kubernetes-dashboard.kube-system.svc.cluster.local (10.110.207.144) 56(84) bytes of data.
|
||
...
|
||
...
|
||
admin@kubenode01:~$
|
||
```
|
||
(Note: This host example above has `iputils-ping` installed)
|
||
|
||
### Kubernetes Node DNS Resolution
|
||
For each of the nodes to know exactly how to communicate with Ceph (and thus MariaDB) endpoints, each host much also have an entry for `kube-dns`. Since we are using Ubuntu for our example, place these changes in `/etc/network/interfaces` to ensure they remain after reboot.
|
||
|
||
Now we are ready to continue with the Openstack-Helm installation.
|
||
|
||
|
||
# Openstack-Helm Preparation
|
||
|
||
Please ensure that you have verified and completed the steps above to prevent issues with your deployment. Since our goal is to provide a Kubernetes environment with reliable, persistent storage, we will provide some helpful verification steps to ensure you are able to proceed to the next step.
|
||
|
||
Although Ceph is mentioned throughout this guide, our deployment is flexible to allow you the option of bringing any type of persistent storage. Although most of these verification steps are the same, if not very similar, we will use Ceph as our example throughout this guide.
|
||
|
||
## Node Labels
|
||
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:
|
||
|
||
**Storage Nodes:** `ceph-storage`
|
||
**Control Plane:** `openstack-control-plane`
|
||
**Compute Nodes:** `openvswitch`, `openstack-compute-node`
|
||
|
||
```
|
||
admin@kubenode01:~$ kubectl label nodes openstack-control-plane=enabled --all
|
||
admin@kubenode01:~$ kubectl label nodes ceph-storage=enabled --all
|
||
admin@kubenode01:~$ kubectl label nodes openvswitch=enabled --all
|
||
admin@kubenode01:~$ kubectl label nodes openstack-compute-node=enabled --all
|
||
```
|
||
|
||
## 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
|
||
```
|
||
|
||
## 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
|
||
```
|
||
|
||
## 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
|
||
```
|
||
*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 ../../..
|
||
```
|
||
|
||
## 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
|
||
```
|
||
*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
|
||
```
|
||
|
||
# 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
|
||
```
|
||
|
||
**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
|
||
NAME REVISION UPDATED STATUS CHART
|
||
bootstrap 1 Fri Dec 23 13:37:35 2016 DEPLOYED bootstrap-0.1.0
|
||

|
||

|
||
admin@kubenode01:~$
|
||
admin@kubenode01:~$
|
||
admin@kubenode01:~$ helm delete --purge keystone
|
||
```
|
||
Please ensure that you use ``--purge`` whenever deleting a project.
|
||
|
||
## Ceph Installation and Verification
|
||
Install the first service, which is Ceph. If all instructions have been followed as mentioned above, this installation should go smoothly. Use the following command to install Ceph:
|
||
```
|
||
admin@kubenode01:~$ helm install --set network.public=$osd_public_network --name=ceph local/ceph --namespace=ceph
|
||
```
|
||
|
||
## Bootstrap Installation
|
||
At this time (and before verification of Ceph) you'll need to install the `bootstrap` chart. The `bootstrap` chart will install secrets for both the `ceph` and `openstack` namespaces for the general StorageClass:
|
||
```
|
||
admin@kubenode01:~$ helm install --name=bootstrap-ceph local/bootstrap --namespace=ceph
|
||
admin@kubenode01:~$ helm install --name=bootstrap-openstack local/bootstrap --namespace=openstack
|
||
```
|
||
|
||
You may want to validate that Ceph is deployed successfully. Here are a couple of recommendations for this.
|
||
|
||
### 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
|

|
||
### 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
|
||
```
|
||
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
|
||

||

|
||
```
|
||
So you can see that galera is enabled.
|
||
|
||
## Installation of Other Services
|
||
Now you can easily install the other services simply by going in order:
|
||
|
||
**Install Memcached/RabbitMQ:**
|
||
```
|
||
admin@kubenode01:~$ helm install --name=memcached local/memcached --namespace=openstack
|
||
admin@kubenode01:~$ helm install --name=rabbitmq local/rabbitmq --namespace=openstack
|
||
```
|
||
|
||
**Install Keystone:**
|
||
```
|
||
admin@kubenode01:~$ helm install --name=keystone local/keystone --namespace=openstack
|
||
```
|
||
|
||
**Install Horizon:**
|
||
```
|
||
admin@kubenode01:~$ helm install --name=horizon local/horizon --namespace=openstack
|
||
```
|
||
|
||
**Install Glance:**
|
||
```
|
||
admin@kubenode01:~$ helm install --name=glance local/glance --namespace=openstack
|
||
```
|
||
|
||
## Final Checks
|
||
Now you can run through your final checks. Wait for all services to come up:
|
||
```
|
||
admin@kubenode01:~$ watch kubectl get all --namespace=openstack
|
||
```
|
||
|
||
Finally, you should now be able to access horizon at http://<horizon-svc-ip> using admin/password
