I'm excited to announce Gruntwork's latest open source tool: Boilerplate! Boilerplate is a cross-platform code generation tool designed specially for DevOps use cases. We built it because Gruntwork is stamping out new AWS architectures for customers all the time. Rather than copy/pasting code and manually customizing it, we wanted to be systematic about it. With Boilerplate, we define our architectures as "boilerplate templates" and every time we want to create a new one, we pass in a set of "boilerplate variables" to customize everything. Boilerplate is a CLI tool, so we can do this manually or in a CI pipeline. And because Boilerplate is optimized for the DevOps use case, we've got lots of handy features: - We expose the entire Go template language - You can generate a single line of code, a single file, or whole folder of files, all dynamically - You can run a shell command and pipe the output directly into a template variable (think building an AMI with Packer and then automatically capturing the value in a template) - You can use "partial templates" embedded in larger templates To see more, check out the blog post from my colleague, Yevgeniy Brikman, below. We're expecting customers will write their own boilerplate templates to assist with developer self-service and to automate internal tasks that are painful to repeat. And it's all free and open source! Take a look and let us know what you think.

Your pull requests need a bodyguard. Enter GitHub Actions. Imagine having a security guard for your code. That's continuous integration (CI) for you. It checks your work before it's allowed to enter the main project. Think of it as a robust spell check, but for code. And GitHub Actions makes it happen once configured properly. When a developer submits a pull request: 1. GitHub Actions can automatically run a scripted set of routines to analyze your code. This usually includes running automated tests, checking coding conventions, and highlighting obvious security concerns. 2. If it passes (devs call this a "green build"), it's ready for review and can be brought into the main project. 3. If it fails (a "red build"), you can configure your code repository not to allow it into the main project. The developer who created the PR should address the failures. You can also configure CI routines to generate documentation and deploy a temporary demo of the new features the PR introduces. I've seen development teams get very creative with GitHub actions and other CI tools. Concerned about security? You can configure customized runners that execute the scripts in your existing cloud environment. Result? Higher quality software with fewer headaches. Note: the premise is simple, but not easy. Your dev team has to be committed to maintaining it, and ensuring it runs reliably. Ask your dev today: Are we using CI? #softwareengineering #engineeringleadership --- We help teams implement great practices like Continuous Integration.

Using a GitOps approach for managing deployments in your Kubernetes cluster can make it much simpler to handle deployments and also to track changes and manage drift. Clusters where people just deploy resources in an ad-hoc fashion tend to get messy quickly. GitOps is the approach where you use a source repo as the source of truth for your deployments and when you want to make changes you open a PR and when approved an operator in your cluster is listening and deploys the changes. With this approach you can also setup audit or gate controls which watch for changes outside the source repository. When these occur you can block them or revert them. Seeing practical examples of how to do things and the code involved always helps to reinforce what you read. In the article below Bora Köstem shows a good example of using ArgoCD, Helm, and Github Actions to deploy apps in a cluster. https://lnkd.in/euDCSJzf

#GitOps What is GitOps? GitOps is a modern approach to continuous delivery that uses Git as a single source of truth for declarative infrastructure and applications. It allows teams to manage and deploy applications using Git workflows. What is FluxCD? FluxCD is a set of continuous delivery tools for Kubernetes that automate the deployment of applications and infrastructure changes. It monitors your Git repository for changes and applies them to your Kubernetes cluster.

🚀 Enhanced My Skills with Docker & Docker Compose! 🚀 I’m excited to share that I’ve taken my containerization skills to the next level by mastering Docker and Docker Compose! 🎉 Docker is a powerful tool that allows for easy packaging, deploying, and running of applications in containers, and with Docker Compose, I can now manage multiple containers effortlessly. 📌 What is Docker Compose? Docker Compose is a tool that allows you to define and run multi-container Docker applications. With just one command, you can start up everything your application needs—databases, APIs, microservices, etc.—all working together in a seamless environment. 📌 Why Docker Compose is Essential? Simplified Setup: Manage and orchestrate multiple services with a single docker-compose.yml file. Consistent Environments: Run the same environment locally as in production, eliminating "it works on my machine" issues. Faster Development: Spin up and tear down entire development environments with ease. Isolation: Services are isolated in containers but can communicate over networks, ensuring flexibility and modularity. 🔧 Technologies I’ve Worked With: 📌 Docker Compose: Configuring multiple services like MySQL, API Gateways, and Spring Boot apps in a simple, structured way. 📌 Networking: Connecting containers to allow communication between services seamlessly. 📌 Volume Management: Persistent storage for databases, ensuring data isn't lost when containers stop. 📌 Dockerfile Optimization: Writing efficient Dockerfiles to ensure faster builds and smaller image sizes. Learning Docker and Docker Compose has streamlined my development process, making it easier to build, test, and deploy applications efficiently. I’m excited to leverage this skill in my future projects!
