hyper.sh provider for virtual-kubelet
=====================================
# Configure for hyper.sh
## Use environment variable
- necessary
- HYPER_ACCESS_KEY
- HYPER_SECRET_KEY
- optional
- HYPER_INSTANCE_TYPE: default s4
- HYPER_DEFAULT_REGION: default us-west-1
- HYPER_HOST: tcp://${HYPER_DEFAULT_REGION}.hyper.sh:443
> You can use You can use either HYPER_HOST or HYPER_DEFAULT_REGION
## Use config file
> default config file for hyper.sh is ~/.hyper/config.json
```
//example configuration file for Hyper.sh
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "xxxxxx",
"email": "xxxxxx"
},
},
"clouds": {
"tcp://*.hyper.sh:443": {
"accesskey": "xxxxxx",
"secretkey": "xxxxxx",
"region": "us-west-1"
}
}
}
```
# Usage of virtual-kubelet cli
```
// example 1 : use environment variable
export HYPER_ACCESS_KEY=xxxxxx
export HYPER_SECRET_KEY=xxxxxx
export HYPER_DEFAULT_REGION=eu-central-1
export HYPER_INSTANCE_TYPE=s4
./virtual-kubelet --provider=hyper
// example 2 : use default config file(~/.hyper/config.json)
unset HYPER_ACCESS_KEY
unset HYPER_SECRET_KEY
export HYPER_DEFAULT_REGION=eu-central-1
./virtual-kubelet --provider=hyper
// example 3 : use custom config file, eg: ~/.hyper2/config.json
$ ./virtual-kubelet --provider=hyper --provider-config=$HOME/.hyper2
```
# Quick Start
## create pod yaml
```
$ cat pod-nginx
apiVersion: v1
kind: Pod
metadata:
name: nginx
spec:
nodeName: virtual-kubelet
containers:
- name: nginx
image: nginx:latest
ports:
- containerPort: 80
```
## create pod
```
$ kubectl create -f pod-nginx
```
## list container on hyper.sh
```
$ hyper ps
