pack8s's Introduction

Packer templates for k8s solo

These are packer templates used to create AWS AMI that run Kubernetes on a single node. You will need to have Packer installed on your local machine and a AWS account.

Support for additional cloud providers is in the works, PR welcome. Currently only Ubuntu and Atomic are supported.

On Ubuntu a docker based deloyment is used while on Atomic, the default systemd units are used.

Usage

Pick your OS of choice (i.e Ubuntu or Atomic)

$ cd ubuntu
$ packer build k8s.json 
... 
==> amazon-ebs: Creating the AMI: k8s_atomic_single_1446562839
    amazon-ebs: AMI: ami-913fe1e2
==> amazon-ebs: Waiting for AMI to become ready...
==> amazon-ebs: Terminating the source AWS instance...
==> amazon-ebs: Deleting temporary security group...
==> amazon-ebs: Deleting temporary keypair...
Build 'amazon-ebs' finished.

==> Builds finished. The artifacts of successful builds are:
--> amazon-ebs: AMIs were created:

eu-west-1: ami-913fe1e2

Start an instance using the AMI that was built.

$ aws ec2 run-instances --image-id ami-913fe1e2 --instance-type t2.micro --key-name k8s

SSH to the running instance and enjoy Kubernetes on a single node
