Kubes is a deployment tool that makes it easier and more fun to work with Kubernetes. Kubes automates 3 main steps. Build a Docker image. Create the YAML files that declare the Kubernetes resources. Run kubectl apply to create the resources on the cluster. It boils everything down to one single command: kubes deploy

AWS docs explain How Spot Fleet Weighting Works under the “Spot Fleet Instance Weighting” section. I’ve read through the doc a few times now, and even so, when I come back to it months later, it still requires some mental wrangling to remember how it works. Been using some “mental” rules to understand how Spot Fleet Weighting works more quickly. Hopefully, you find these notes helpful also.

One of the biggest game-changers to spot instances are spot fleets. I mentioned how you could save 50%-90% when you take advantage of spot instance pricing in: How Does Spot Pricing Work? Spot fleets is where things get even more interesting. With a normal spot instance request, you place a bid for a specific instance type in one specific AZ and hope you get it. With spot fleets, you can request a variety of different instance types that meet your requirements. Additionally, you can spread your spot fleet bet across multiple AZs to increase the likelihood of getting your instance fulfilled. It’s like playing rollette and being able to bet a single chip on multiple numbers. Insanely cool! The method dramatically increases the chances of you getting instances available at your spot bid price. Like I said, game-changer.

Have you ever been asked to deploy a branch of code to the staging or uat environment but cannot because the environment is currently in used by someone else or another feature? Usually, you end up having to wait until the environment free. Ultimately, after this happens often enough a common request is to build additional environments. This can take some time though, so you still have to wait.

This is an introductory guide to ufo, an ECS deployment tool, with AWS Fargate. Ufo helps you deploy Docker images to AWS ECS. With Fargate, you can run docker containers without having to manage servers, for an interesting “serverless” option.

This is an introductory guide to ufo, an ECS deployment tool. Ufo helps you deploy Docker images to AWS ECS quickly. One pretty neat thing about ufo is that it provides direct access and control to the ECS Task Definition. So you can customize your ECS container options to your heart’s content. We’ll also talk about some of the resources that ufo creates.

There are some pretty big changes for ufo version 4. Here’s what’s new: Fuller CLI Toolkit Commands Load Balancer Support Updated Tutorial Guide Security Groups Improved Fargate Support Extra Env Support CloudFormation Implementation Upgrade Guide

Recently upgraded ufo to add support for ECS Fargate. As part of this, I had a chance to look at the pricing for Fargate. Found out that ECS Fargate’s pricing is competitive to Heroku’s offering. The pricing makes a lot of sense because they offer a similar value proposition. We do not have to manage the servers.

Docker is kind of like git in a sense that there are only a few commands to learn to for it be useful. This tutorial focuses on the docker commands that I find myself most commonly use. This article assumes that you have a general idea of what docker is and have it installed and set up already. Hopefully, it serves as handy reference or cheatsheet for useful common docker commands.
