# Moon Platform Setup
## Docker Installation
```bash
apt update
apt install -y docker.io
```

## K8S Installation
Choose the right K8S platform
### Minikube
```bash
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.21.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
```

### Kubeadm
see: https://kubernetes.io/docs/setup/independent/install-kubeadm/
```bash
apt-get update && apt-get install -y apt-transport-https
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
EOF
apt-get update
apt-get install -y kubelet kubeadm kubectl
```

## Moon Deployment
### Initiate K8S
```bash
cd $MOON_HOME
bash tools/moon_kubernetes/init_k8s.sh
```

Wait until all the kubeadm containers are in the `running` state:
```bash
watch kubectl get po --namespace=kube-system
```
    
You must see something like this:

    $ kubectl get po --namespace=kube-system
    NAME                                        READY     STATUS    RESTARTS   AGE

### Deploy Moon
```bash
cd $MOON_HOME
sudo bash tools/moon_kubernetes/start_moon.sh
```

Wait until all the Moon containers are in the `running` state:
```bash
watch kubectl get po --namespace=moon
```

You must see something like this:

    $ kubectl get po --namespace=moon
    NAME                                   READY     STATUS    RESTARTS   AGE

### Troubleshoot
check *Consul* for: 
- *Components/Manager*, e.g. 
```json
{
  "port": 8082, 
  "bind": "0.0.0.0", 
  "hostname": "manager", 
  "container": "wukongsun/moon_manager:v4.3.1", 
  "external": {
    "port": 30001, 
    "hostname": "$MOON_HOST"
  }
}
```
- *OpenStack/Keystone*: e.g. 
```json
{
  "url": "http://keystone:5000/v3", 
  "user": "admin", 
  "password": "p4ssw0rd", 
  "domain": "default", 
  "project": "admin", 
  "check_token": false, 
  "certificate": false, 
  "external": {
    "url": "http://$MOON_HOST:30006/v3"
  }
}
```
