Nuts and Bolts

When Heroku ended its free tier many years ago, a wave of alternatives like Render, Vercel, Fly.io, and Railway sprouted up everywhere. Some have free tiers, but even with VC money, they all come with limitations. The golden free era is effectively over. 😭

Jets 6.0 is a Deployment Service. Jets makes it easy to deploy and run your app on Serverless. It packages up your code and runs it on AWS Lambda. Jets can deploy Rails, Sinatra, Hanami, and any Rack app.

I spent a little time on Dynomite as part of working on the huge Jets 5 Release. This led to a Dynomite 2 release that’s ActiveModel Compatible.

Jets 5 is a massive release. I started it a few months ago, and it just snowballed. Almost every line of the Jets core source code was touch. I think users will be thrilled with the Jets 5 results.

Jets v4 is an interesting release. It supports Ruby 3.2 on AWS Lambda even before AWS official support for Ruby 3.2. Read along to find out how this was done.

With cost estimates, you will be able to see how much your infrastructure costs. The estimate is saved to Terraspace cloud for visibility and historical viewing. Here’s what it looks like on the dashboard.

In this post, you’ll get an introduction to Terraspace Cloud. What is Terraspace Cloud? Terraspace Cloud is a nice addition to the Terraspace Framework. Terraspace Cloud adds extra features to Terraspace. GUI Dashboard and History: When working with multiple stacks, it can become hard to remember all the stacks you or others on your team have deployed. Terraspace Cloud helps you visualize the stacks by saving them and providing a web dashboard with deployed stacks, history, logging, and resources. Know who deployed what and when. Team and Permissions Management: Fine-grain permission control over access. You can create teams and define permission that target dev vs prod environments. CI/CD Integration: Integration with popular CI/CD systems like GitHub Actions, GitLab Pipelines, etc. GitHub Pull Request and GitLab Merge Request integration provide a comment with a link to the visual dashboard. Real-Time Logging: Terraspace captures logs that you see in your terminal and stream them live to the Dashboard. You can share this url to teammates who have access to the project. Cloud Cost Estimation: Terraspace Cloud provides cost estimates for your Terraform resources. Terraspace integrates the infracost estimation reports with the Terraspace Cloud dashboard and Pull Request comments. Terraspace Cloud provides these additional conveniences as an optional paid managed service. Terraspace Cloud Pricing

Terraspace Cloud is a nice addition to Terraspace. Terraspace Cloud adds extra features and conveniences to the Terraspace Framework like Team Management, Permissions, History, and a GUI visual interface. It’s specifically designed it work with Terraspace. Terraspace Cloud provides these additional conveniences as an optional paid managed service. It also hopefully provides a means to support the project financially. The Terraform Framework itself is open source and free to use. You can start using Terraspace Cloud with the Terraspace Framework starting in version 2.0.

This post will detail the steps to get a serverless slack command running on AWS Lambda using the Jets Serverless Ruby framework. We’ll make something fun: a command that takes in a URL, scrapes all the images on the page, filters the images using AWS image recognition, and posts the filtered images to the current slack channel. For example:

Originally called Lambda Gems, Serverless Gems has been rebuilt from the ground up. It provides better support for multiple versions of Ruby, notable Ruby 2.7. Jets v3 uses Serverless Gems for a developer-friendly experience.

Today, we’ll talk about some deployment tools in the Kubernetes world. We’ll talk a little bit about why tools are used on top of kubectl. We’ll compare 3 different tools in the Kubernetes world focused on the deployment side of things: Kustomize, Helm, and Kubes. Then we’ll elaborate on the features that Kubes offers.

Terraspace makes it easy to use Terraform modules sourced from your own git repositories, other git repositories, or the Terraform Registry. The git repos can be private or public. This is an incredibly powerful feature of Terraspace because it opens up a world of modules for you. Use any module from anywhere.

In the last post, we provided an introduction to the for in construct. This post provides more examples, shows local assignment, and covers how to set default attribute values. Remember, for is useful for data structure manipulation. Sometimes you may not get the data in the structure that is easy for you to work with, so understanding how to manipulate the data structure in Terraform can be quite useful.

In this post, we’ll cover the Terraform for in loop construct. Though it performs looping, its primary purpose is really for manipulating data structures. You can do a few things to data structures with it:

In this post, we’ll take on nested loops with Terraform. Terraform is declarative, so a nested loop can be tricky. This post hopes to help with that.

In the previous post, we established loop fundamentals. The loops were pretty basic, though. We were only able to assign a single attribute for each resource per iteration. In this post, we’ll learn how to assign multiple attributes per iteration.

In this post, we’ll cover Terraform looping constructs. Terraform is declarative, so it’s looping structure may seem weird to those used to procedural programming loops. There are a few ways to performing looping with Terraform. We’ll cover the looping constructs that specifically work at the resource level. They handle resource creation itself. There are two of them:

In this post, we’ll cover how to perform conditional logic with Terraform. It’ll be a little weird looking for those who are not used to the Terraform declarative syntax. There are only a few ways to do conditional logic with Terraform:

In this post, we’ll review the basic Terraform building blocks from the previous post, Terraform HCL Intro 1: Resources, Variables, Outputs, and compare them to a “function”. This is a contrived analogy, but folks find it helpful. You’ll also learn about Terraform locals.

This is the start of a series of posts to help introduce and learn the Terraform HCL language. It is written for those with an elementary understanding of programming already. This allows us to cover things effectively instead of being stuck in the weeds.
