# CloudStack Cluster API Provider (CAPC) Release v.0.4.0 Evaluation Deployment Guide
2+
3+
This document defines a manual deployment process suitable for evaluating this CAPC release.
4+
5+
## Evaluation Environment Pre-Requisites:
6+
7+
### - A running Kubernetes cluster for hosting CAPC
8+
9+
This should be an easily disposable/re-creatable cluster, such as a locally-running kind (Kuberetes in Docker) cluster.
10+
11+
Your KUBECONFIG file's *current-context* must be set to the cluster you want to use.
12+
13+
### - CAPI clusterctl v1.0.1 (https://github.com/kubernetes-sigs/cluster-api/releases/tag/v1.0.1)
14+
15+
This process has been tested with this version of clusterctl. Subsequent 1.0.x versions should work as well.
16+
17+
### - A CloudStack Environment with the following resources defined
18+
- Zone
19+
- Network
20+
- CAPI-compatible QEMU template (i.e., created with https://github.com/kubernetes-sigs/image-builder)
21+
- Machine Offerings (suitable for running Kubernetes nodes)
22+
- apikey and secretkey for a CloudStack user having domain administrative privileges
23+
- Available ACS IP Address for the k8s Control Plane endpoint (Shared network: available IP address in the network range; isolated network: public IP address)
24+
25+
## Deployment Steps
26+
### Define Identity Environment Variable
27+
28+
An environment variable named CLOUDSTACK_B64ENCODED_SECRET must be defined, containing the base64 encoding of a
29+
cloud-config properties file. This file is of the form:
30+
31+
```
32+
[Global]
33+
api-url = <urlOfCloudStackAPI>
34+
api-key = <cloudstackUserApiKey>
35+
secret-key = <cloudstackUserSecretKey>
36+
```
37+
After defining this in a file named cloud-config, create the environment variable with:
38+
39+
```
40+
export CLOUDSTACK_B64ENCODED_SECRET=$(base64 -w0 -i cloud-config 2>/dev/null || base64 -b 0 -i cloud-config)
41+
```
42+
43+
For security, delete this cloud-config file after creating this environment variable.
44+
45+
### Deploy the supplied container image archive (.tar.gz) to a suitable image registry.
46+
47+
*We use https://github.com/kubernetes-sigs/cluster-api/blob/main/hack/kind-install-for-capd.sh to launch a local
48+
docker registry integrated into a kind cluster for lightweight development and testing.*
49+
50+
- On a computer with docker, load the provided cluster-api-provider-capc.tar.gz to docker:
51+
```
52+
docker load --input cluster-api-provider-capc_v0.4.0.tar.gz
53+
```
54+
55+
This will create image *localhost:5000/cluster-api-provider-cloudstack:v0.4.0* in your local docker. This is suitable
56+
for pushing to a local registry.
57+
58+
- (Optional) Tag this image for your registry.
59+
```
60+
docker tag localhost:5000/cluster-api-provider-cloudstack:v0.4.0 <yourRepoFqdn>/cluster-api-provider-cloudstack:v0.4.0
61+
```
62+
63+
Push it to your registry (localhost:5000 if using local registry)
64+
```
65+
docker push <yourRepoFqdn>/cluster-api-provider-cloudstack:v0.4.0
66+
```
67+
68+
### Create clusterctl configuration files
69+
A cluster-api.zip file has been provided, containing the files and directory structure suitable for configuring
70+
clusterctl to work with this interim release of CAPC. It should be restored under $HOME/.cluster-api. It contains:
71+
72+
```
73+
Archive: /Users/jweite/Dev/cluster-api-cloudstack-v0.4.0-assets/cluster-api.zip
74+
* clusterctl.yaml
75+
* dev-repository/
76+
* dev-repository/infrastructure-cloudstack/
77+
* dev-repository/infrastructure-cloudstack/v0.4.0/
78+
* dev-repository/infrastructure-cloudstack/v0.4.0/cluster-template.yaml
79+
* dev-repository/infrastructure-cloudstack/v0.4.0/cluster-template-managed-ssh.yaml
80+
* dev-repository/infrastructure-cloudstack/v0.4.0/cluster-template-ssh-material.yaml
81+
* dev-repository/infrastructure-cloudstack/v0.4.0/infrastructure-components.yaml
82+
* dev-repository/infrastructure-cloudstack/v0.4.0/metadata.yaml
83+
```
84+
85+
*Note: If you already have a $HOME/.cluster-api we strongly suggest you delete or stash it.*
86+
87+
```
88+
cd ~
89+
mkdir .cluster-api
90+
cd .cluster-api
91+
unzip cluster-api.zip
92+
```
93+
94+
### Edit the clusterctl configuration files
95+
- **clusterctl.yaml:** in the *url* attribute replace \<USERID\> with your OS user id to form a valid absolute path to infrastructure-components.yaml.
96+
97+
- **dev-repository/infrastructure-cloudstack/v0.4.0/infrastructure-components.yaml:** if you're not using a local registry modify the capc-controller-manager deployment, changing the spec.template.spec.containers[0].image (line 617) to correctly reflect your container registry.
98+
99+
### Deploy CAPI and CAPC to your bootstrap Kubernetes cluster
100+
```
101+
clusterctl init --infrastructure cloudstack
102+
```
103+
104+
### Generate a manifest for the CAPI custom resources needed to allocate a workload cluster.
105+
106+
*Set the below environment variables as appropriate for your CloudStack environment.*
107+
108+
```
109+
CLOUDSTACK_ZONE_NAME=<MyZoneName> \
110+
CLOUDSTACK_NETWORK_NAME=<MyNetworkName> \
111+
CLOUDSTACK_TEMPLATE_NAME=<MyTemplateName> \
112+
CLOUDSTACK_CONTROL_PLANE_MACHINE_OFFERING=<MyServiceOfferingName> \
113+
CONTROL_PLANE_MACHINE_COUNT=1 \
114+
CLOUDSTACK_WORKER_MACHINE_OFFERING=<MyServiceOfferingName> \
115+
WORKER_MACHINE_COUNT=1 \
116+
CLUSTER_ENDPOINT_IP=<AvailableSharedOrPublicIP> \
117+
CLUSTER_ENDPOINT_PORT=6443 \
118+
KUBERNETES_VERSION=<KubernetesVersionOnTheImage> \
119+
CLUSTER_NAME=<MyClusterName> \
120+
clusterctl generate yaml --from ~/.cluster-api/dev-repository/infrastructure-cloudstack/v0.4.0/cluster-template.yaml > clusterTemplate.yaml
121+
```
122+
123+
### Review the generated clusterTemplate.yaml and adjust as necessary
124+
125+
126+
### Provision your workload cluster
127+
128+
```
129+
kubectl apply -f clusterTemplate.yaml
130+
```
131+
132+
Provisioning can take several minutes to complete. You will see a control plane VM created in CloudStack pretty quickly,
133+
but it takes a while for it to complete its cloud-init to install Kubernetes and become a functioning control plane.
134+
Allocation of the worker node(s) (with *md* in their VM names) won't occur until the control plane is operational.
135+
136+
You can monitor the CAPC controller as it conducts the provisioning process with:
137+
```
138+
# Get the full name of the CAPC controller pod
139+
kubectl -n capc-system get pods
140+
141+
# Tail its logs
142+
kubectl -n capc-system log -f <CAPCcontrollerPodFullName>
143+
```
144+
145+
### Fetch a kubeconfig to access your cluster
146+
```
147+
clusterctl get kubeconfig <clusterName> > <clusterName>_kubeconfig
148+
```
149+
150+
You can then either export a KUBECONFIG environment variable pointing to this file, or use kubectl's --kubeconfig=<filePath>
151+
flag.
152+
```
153+
export KUBECONFIG=<clusterName>_kubeconfig
154+
```
155+
156+
### Examine the provisioned Kubernetes Cluster's nodes
157+
```
158+
kubectl get nodes
159+
```
160+
Expect to see a control plane and a worker node reported by Kubernetes. Neither will report that they are ready
161+
because no CNI is installed yet.
162+
163+
### Install Cilium CNI
164+
```
165+
cilium install
166+
```
167+
The above command presumes that the cilium installer is present on the local workstation.
168+
169+
It will take a minute while it waits for cilium to become active.
170+
171+
### Confirm that Cluster is Ready for Work
172+
```
173+
kubectl get nodes
174+
```
175+
Expect now to see both nodes list as ready.
176+
177+
### Conclusion
178+
At this point the workload cluster is ready to accept workloads. Use it in the usual way via the kubeconfig generated
179+
earlier
180+
181+
### Cluster Deletion
182+
As mentioned in the preface, CAPC is not yet able to delete workload cluster. To do so manually we recommend
183+
simply tearing-down the kind bootstrap cluster, and then manually deleting the CloudStack VMs created for it
184+
using the CloudStack UI, API or similar facilities.
