How to Run

Install Rancher High-Availability Cluster

Generate ssh keys for non-password login to the hosts inside hosts.yml

Prepare install.yml, hosts.yml, referring to the examples in config, then run

docker run --rm -v `pwd`:/outputs \
                -e ACTION=install_rancher \
                -e CONFIG="$(cat config/install.yml)" \
                -e HOSTS="$(cat config/hosts.yml)" \
                -e SSH_KEY="$(cat id_rsa)" \
                garyhuang123/rops:v0.1.0

Note: /outputs is used internally to save the cluster's state files, including kubeconfig, rkestate.

Upgrade Existing Cluster & Rancher

Generate ssh keys for non-password login to the hosts inside hosts.yml

Prepare upgrade.yml, hosts.yml, kube_config_rancher_cluster.yml, rancher_cluster.rkestate, referring to the examples in config, then run

docker run --rm -e ACTION=upgrade_rancher \
                -e CONFIG="$(cat config/upgrade.yml)" \
                -e HOSTS="$(cat config/hosts.yml)" \
                -e SSH_KEY="$(cat id_rsa)" \
