## Using The Jumpbox
### Connect to Jumpbox
```
ssh -i ./keys/cluster \
thehardway@$jumpboxDnsLabel.westus.cloudapp.azure.com
```
### Copy the Private Key to Jumpbox
```
scp -i ./keys/cluster \
./keys/cluster \
thehardway@$jumpboxDnsLabel.westus.cloudapp.azure.com:~/cluster
```
### Connecting to Other VMs
```
# on the jumpbox
#connect to the second controller
ssh -i ./cluster \
thehardway@10.240.0.31
#or
ssh -i ./cluster \
thehardway@controller-1
```
