README.md

Deploy a Kubernetes environment in SoftLayer with a single command! It's that simple.

Prerequisites:

  1. PIP - sudo apt-get install python-pip python-dev build-essential
  2. SoftLayer CLI - sudo pip install --upgrade pip softlayer
  3. Ansible v2.0 or newer- sudo apt-get install ansible
  4. sshpass - sudo apt-get install sshpass
  5. A default SSH key must exist on your local platform. If one does not exist, this can be created via the command ssh-keygen -t rsa -N "" -f ~/.ssh/id_rsa.

NOTE: If you encounter SSH issues running from Ubuntu, install sudo pip install requests[security] first. If that does not eliminate the issue, you may be hitting an issue with GNOME Keyring. See this article for a fix.

Deployment:

Follow this procedure:

  1. First clone this project: git clone https://github.com/patrocinio/kubernetes-softlayer.git
  2. Edit the kubernetes.cfg file to enter the following SoftLayer configuration
  3. Mandatory fields:
  • Optional ones:
    • DATACENTER: Run the following command to obtain the data center code: slcli vs create-options | grep datacenter
    • DOMAIN: hostname domain
    • SERVER_TYPE: bare for bare metal; anything else for virtual servers
    • For virtual servers:
      • CPU: Define the number of CPIUs you want in each server
      • MEMORY: Define the amount of RAM (in MB) in each server
    • For bare metal:
      • SIZE: Run slcli server create-options for values
    • PUBLIC_VLAN: Define the public VLAN number
    • PRIVATE_VLAN: Define the private VLAN number
  1. Run the following command: deploy-kubernetes.sh

Simple, no?

Testing the environment

We recommend running the Guestbook application to test your environment. Log on to the kube master and follow these steps:

mkdir guestbook
cd guestbook
git clone https://github.com/kubernetes/kubernetes.git
cd kubernetes
git reset --hard 6a657e0bc25eafd44fa042b079c36f8f0413d420
kubectl create -f examples/guestbook/all-in-one/guestbook-all-in-one.yaml

You can monitor the progress of the deployment by typing the following command:

kubectl get pods

After a few seconds (or minutes), you should see the following result:

[root@kube-master-1 guestbook]# kubectl get pods
NAME                 READY     STATUS    RESTARTS   AGE

frontend-yg8ci       1/1       Running   0          15m
frontend-yj0ca       1/1       Running   0          15m
redis-master-p8tqa   1/1       Running   0          15m
redis-slave-c0ydz    1/1       Running   0          15m
redis-slave-erlp0    1/1       Running   0          15m
