Introducing ec2-instance-selector

When provisioning a spot fleet, getting the correct instance type can be a little bit overwhelming, log in to the console, look for instance capacity, etc That's why AWS provides us a really useful tool from the cli, ec2-instance-selector (https://github.com/aws/amazon-ec2-instance-selector) This makes our lives much easier. You just need to run the command passing resource criteria like vcpus, network performance, ram, etc. Be sure to have your AWS credentials loaded when yo

Hitting Github API REST with the Linux console

The very first step to hit any API REST is to read the documentation because every API is a world. While some of them are very intuitive, others require a lot of time on thinking about how to make every single call due to the resource's format required. The Github API REST has calls requiring a very specific format of input parameters. Might be in the header, in the URL's path, as URL GET parameters, or inside a JSON formatted body. But this is not all, because the answer wil

Cross account access to S3 using IRSA in EKS with Terraform as IaaC

We have many options to get cross-account access to resources, but when talking about the Kubernetes cluster, things can get a little bit tricky! So, in this blog, I'll share a solution to do it in the safest way using the principle of least privilege. A typical scenario is to have two accounts, Account A, with an EKS cluster and Account B with an S3 bucket (example_bucket) that needs to be accessed by a pod from account A. We have many options for this: We can create a bucke

Again that mail about the need of rotating the Github Tokens of your pipelines?

“CodeStar Connect” will release you of that pain. Everybody knows the inconvenience of working with secrets like Tokens or Webhooks: You need to create them, save them in the Parameter Store to avoid leakage, and rotate them every couple of months. But now, using CodeStar connections and the Github App on AWS you are completely free of them! Creating this connection is as simple as you can see in this link; however, in Terraform you will find that it’s as easy as in the AWS M

Your AWS invoice is getting bigger and bigger because of CloudWatch Logs, and you don't know why?

If when you look at your invoice you see that the amount you have to pay because of CloudWatch Logs keeps growing, this tip will definitely interest you. One of the main items that make the monthly CloudWatch Logs charge increase is PutLogEvents, which is the ingestion of logs into log groups. But the problem now is to find how much each log group is getting charged to know how to reduce the costs. It might seem that there is not a straightforward way to do this. However, the

Why are organizations moving towards containerization?

As a company's operations grow, so does its IT system. Any change can present a challenge because new features are added and scaled. Containerization has evolved over the years and has allowed companies to grow while maintaining an efficient organization. Just as a businessman revolutionized the shipping industry more than 60 years ago by using containers the size of a trailer to transport merchandise; Today's container technology is changing how companies deploy and use appl

Every format with its parser

In this Teratip scenario, we are in a GNU/Linux console environment, which could be inside a Jenkinsfile for example, and we need a JSON object. A very common situation actually. Along many years we have seen things like: echo '{"channel":"main","text":"Hello %%USER%%"}' > message.json With also very complex to read sed structures to fill placeholders. Or even run a sh script in a jenkinsfile that calls python code to be able to use the python library to create the JSON and l

The future of e-commerce

In recent months, electronic commerce has acquired greater relevance as a result of the digital transformation due to Covid-19. This has made it necessary for companies that are not online to quickly centralize their sales transactions in virtual channels. In 2021, it began to require companies to continue to maintain an accelerated pace of digital maturation. Likewise, it is not only a matter of organizations starting their operations online by adopting an e-commerce platfor

Terraform workspaces, direnv, dotenv, and mental sanity

Once you have all your environments working with Direnv, Advanced Direnv for Devops, if you are working with Terraform namespaces there is another improvement you can make to automate further. We use another directive from direnv called watch_file, which reloads the environment each time a particular file is changed. We can point this directive to the .terraform/workspace file, which holds the currently selected workspace in Terraform. The following code in the .envrc file im
