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. Copy the file .envrc-template as .envrc: cp .envrc-template .envrc
3. Mandatory fields:
   • RESOURCE_PREFIX
   • API_KEY: Check https://cloud.ibm.com/docs/account?topic=account-userapikey#create_user_key to see how you can generate an API key
4. Optional ones:
   • TF_VAR_NUM_WORKERS: The number of worker nodes
   • TF_VAR_NUM_MASTERS: The number of master nodes
   • KUBELET_PORT_NUMBER: The port number that kubelet is listening (default is 10250)
   • TF_VAR_CLOUD_REGION: The IBM Cloud region where the cluster is deployed
5. Load the file in the current shell:. ./.envrc
6. Run the following command:make all

Simple, no?

The process will go through a few phases:

• It creates the cloud resources, using Terraform
• It configures the virtual machines, using Ansible
