Note: Wiki in progress (added draft notes)

Infra Setup

  1. Create a VM (VCPU:12, RAM: 64 GB, Storage: 160 GB)

    1. Size is based on minimum ONAP components (AAF, Consul, Dmaap, DCAE)

  2. Download RKE version (For k8s compatibility - check https://github.com/rancher/rke/releases?page=1)

    1. wget https://github.com/rancher/rke/releases/download/v1.2.5/rke_linux-amd64   (https://rancher.com/docs/rke/latest/en/installation/) 

    2. OR  https://github.com/rancher/rke/releases/download/v1.2.8/rke_linux-amd64  (https://github.com/rancher/rke/releases/tag/v1.2.8)

    3. OR https://github.com/rancher/rke/releases/download/v1.3.7/rke_linux-amd64  (Note: nameserver 8.8.8.8 to the first line of /etc/resolv.conf)

    4. OR wget  https://github.com/rancher/rke/releases/download/v1.3.11/rke_linux-amd64  (https://github.com/rancher/rke/releases/tag/v1.3.11)

  3. mv rke_linux-amd64 rke

  4. chmod +x rke

  5. export PATH=$PATH:.

  6. rke config (to specifiy cluster config)

    1. copy  ssh_key_path: /home/ubuntu/onap_dev    (chmod 644 onap_dev)

    2. optionally attached file can be edited; change VM/IP and key
