Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. I’m using it for Nousmotards and decided to build an Ansible role for it to make it simpler to deploy. Why did I built it as other projects like Kargo already exists?

That’s what I did: This role bootstrap a Kubernetes cluster based on CoreOS Container Linux for production usages.

As I wanted to upgrade it and because it has been asked several time, I upgraded the consul-template Ansible role to manage official binaries (and upgrades). Here are the new vars: consul_template_version:'0.11.0'consul_template_arch:'linux_amd64'consul_template_http_src:"https://github.com/hashicorp/consul-template/releases/download/v{{consul_template_version}}/consul_template_{{consul_template_version}}_{{consul_template_arch}}.zip" You can of course find the role to Ansible Galaxy: https://galaxy.ansible.com/deimosfr/consul-template/ I hope you’ll enjoy this new version :-)

You simply have to set (or let them by defaults) vars: # Packer version to install packer_version: '0.7.5' # Packer destination folder packer_destination: '/usr/bin' It will install the desired version :-)

For my company, I recently had to find a good solution to make Snapshots from Instance IDs or from tags on AWS. I made several searches but unfortunately didn’t find what I was searching for. That’s why I started to make a tool to do this kind of job. It’s written in Python and requires the Boto library. Here is what you can do with Simple EC2 snapshots: The tool is open source and can be downloaded on GitHub :-).
