Can you use ECS without DevOps

Welcome Use your imagination and assume that some team was encouraged to migrate from Azure AppService. It was a decision at a high level, so the small dev team needs to migrate into AWS. What’s the issue you can ask? They have no experience with Amazon Web Services, also they don’t have a “DevOps” person. The app is a JAR file. AppService allowed them to put a file into the service and run it on production, without any issues. Continue reading

How to use Lambda as a glue?

Welcome Let’s keep this article short. The topic is rather popular, but not very well documented. It’s based on quite a popular issue, which is about untagged EC2. Sometimes developers launch virtual machines, without tags. Why it’s so important? Because without tags, you have no idea about the machine’s purpose. You have no owner, now, project, no cost center, etc. I know that some of these things can be checked with CloudTrail, however, it’s still about keeping the environment clean. Continue reading

Salt on Graviton

Welcome It will be nice to solve another real-world problem, isn’t it? For example machines in private subnets, behind the NAT, or on rack shelves in an office. All of them need to be managed - at least from time to time. Ansible is great, I appreciated the creators of this tool. It helps me a lot! In different cases, environment. I remember when I was a bit younger, a very popular interview question was - what is the difference between Ansible and Chef/Puppet ? Continue reading

Sailing with AWS Lightsail

Welcome I have a daughter! What a piece of news, isn’t it? I can also add again the same line: Newsletter is very time-consuming, and being a consultant is time-consuming. Everything is time-consuming. However, I had some spare time to play a bit with a small client’s project. For example, not everyone needs cutting-edge technology, Kubernetes, and functional programming. Sometimes we just need a small VM with IPv4, for PoC, or small old-style application, or even workshops about Linux administration. Continue reading

CDK8S workflow example

Welcome After a long break(again!) - I’m back. Older, more tired, and handsome as always. Newsletter is very time-consuming, and being a consultant is time-consuming. Everything is time-consuming. That’s why I decided to write this post with a bit different approach. Let’s talk about processes. The tech part is still most important, unfortunately, sometimes it’s not the key. So what is CDK?(generated with rytr) CDKs are a set of tools that enable developers to make use of the cloud environment. Continue reading

Cloud-init with DigitalOcean

Welcome Another build something yourself article. The last one was focused on Kubernetes. Now I will try to build infrastructure for a bit different side-project. I always want to learn SaltStack. To be honest, I’m a huge fan of Ansible which is boring, but works. However, sometimes I have a problem with keeping my developers account synced. Also adding multiple users and track their settings is hard without states. So I decided to get into the new toolbox. Continue reading

EKS on speed

Welcome Let’s build some stuff. Today on AWS(EKS). Today with popular solutions and almost without coding(in YAML). Today focus on speed and simplicity. Additionally no CI/CD. Components I will keep it simple. Terraform aws cli docker helm curl dig, kubectl, emacs Building infrastructure Setup First steps. I need to build some infrastructure. As almost everyone use Terraform for building and managing resources I decided to use it too. Based on Terrafrom EKS module I’ve created a sample manifest. Continue reading
