![]() On Linux, macOS, or using WSL 2 you can do this using the following command: Note that if your binary needs other resources, like CA certificates, then these would also need to be included in the final image.Īs we are leveraging BuildKit in this blog post, you will need to make sure that you enable it by using Docker 19.03 or later and setting DOCKER_BUILDKIT=1 in your environment. It then simply copies the resulting binary from the first stage to its filesystem. The second stage, bin, uses a scratch (i.e.: empty) base image. It then sets the working directory in the container, copies the source from the host into the container, and runs the go build command from before. Note that we can define which version of Go we want to use. Alpine uses the musl C library and is a minimalist alternative to the regular Debian based Golang image. The first stage, build, starts from the Go Alpine image. This Dockerfile is broken into two stages identified with the AS keyword. The same can be achieved using the following Dockerfile: You can easily build this into a binary using the following command: It will cover building, testing, CI, and optimization to make your builds quicker. This is the first of a series of blog posts that will show you how to use Docker for Go development. A good example of this is that we use gRPC for many projects and so require a specific version of protoc that works with our code base. Even with this toolchain we often run into issues like mismatched versions of Go, missing dependencies, and slightly different configurations. The Go toolchain is great– providing fast compile times, built in dependency management, easy cross compiling, and strong opinionation on things like code formatting. Docker is also a great tool for defining your development environment in code to ensure that your team members and the CI are all using the same set of tools. Many people use Docker as a way to run application dependencies, like databases, while they’re developing locally and for containerizing their production applications. I’ve been on more than one team where “works on my machine” has been exclaimed or written in all caps on Slack and I’ve spent a lot of time debugging things on the CI which is incredibly painful. You’ll find issues because the version of the tool you’re using is different to that used by someone on your team, or, worse, the CI. This problem continues as you spend more time in the team. Often there will be an onboarding document of some sort for setting up your environment but in my experience, this is never up to date and you always have to ask someone for help with what tools are needed. This is usually a combination of learning the code base and getting your environment setup. The "behind the scenes": what tools I used to write this book.When joining a development team, it takes some time to become productive.If you don't want to watch everything, you can jump to the chapter you want. A quick video explaining a bit the Mouseless Development Environment we build throughout the book.A sample of the book with the whole table of content.The cherry of the cake: you might learn two or three things about Linux-based systems, especially if you don't use the shell often. ![]() I've written this book to give away everything I know for your hands to stay on the keyboard when you work with plain text. It's like multitasking: it's tiring and ineffective. Switching your hands between the keyboard and the mouse takes cognitive energy. Why would you be interested by such a book? I sold already 317 books and the craziest part: nobody asked for a refund! I had only positive feedback. Its lengthy name: Building Your Mouseless Development Environment, powered by amazing tools like Arch Linux, i3, Zsh, the Almighty tmux of course, and Neovim. my first book is out for more than one month already! I'm so happy to write that, you have no idea. I didn't have any job, only the computer I was traveling with and some clothes. With difficulties and luck, I ended up with my girlfriend in a temporary place. I had to come back in Europe without any flat (I was subleasing it for 6 months). But I was working full time and I also knew I wanted to travel, so I put the project on hold.Īfter some good old burnout due to my job, I began to travel in Asia in January 2020. ![]() One and a half year ago, I was wondering: would anybody be interested by a book describing how to build a system where the Linux shell would be the most important tool, from an empty hard disk to a complete development environment? Would anybody like some guidance to build their first "Mouseless Development Environment"?
