We'll launch Kubernetes on RancherOS on Amazon EC2.
Choose rancheros-v0.3.1-hvm-1 image.
Configure Instance Details -> Advanced Details
Enter User data. Use either:
#cloud-config
rancher:
environment:
ETCD_DISCOVERY: <discovery_url>
FLANNEL_NETWORK: <flannel_network>
K8S_MASTER_PORT: 8080
K8S_PORTAL_NET: 10.100.0.0/16
services_include:
- https://raw.githubusercontent.com/imikushin/rancheros-k8s/master/k8s-common.yml: true
- https://raw.githubusercontent.com/imikushin/rancheros-k8s/master/k8s-master.yml: trueor:
#cloud-config
rancher:
environment:
ETCD_DISCOVERY: <discovery_url>
FLANNEL_NETWORK: <flannel_network>
services_include:
- https://raw.githubusercontent.com/imikushin/rancheros-k8s/master/k8s-common.yml: true
- https://raw.githubusercontent.com/imikushin/rancheros-k8s/master/k8s-minion.yml: trueas a template.
Replace <discovery_url> with a real NEW discovery URL for your cluster, e.g.
https://discovery.etcd.io/daa02a8fafee1519ea54795a14965d3c
Replace <flannel_network> with a CIDR range for flannel overlay network. This CIDR should not overlap
with any existing network you are using, e.g. 10.255.0.0/16
Every time you recreate your cluster, get a new etcd discovery URL for use in your instances' cloud-config
curl "https://discovery.etcd.io/new?size=1"
WARNING: In case you try to reuse this URL for another cluster, your etcd nodes will try to become
peers in another (possibly dead) cluster.
