Short Description
Go (golang) is a general purpose, imperative programming language. Maintained by Resin.io.
Full Description

This image is part of the resin.io base image series for IoT devices. The image is optimized for use with resin.io and resinOS, but can be used in any Docker environment running on the appropriate architecture.

What is resin.io?

Resin.io is the simplest way to build, deploy, and manage containers on a fleet of connected devices. Resin.io brings a modern developer workflow to the Internet of Things, enabling rapid innovation at every stage and scale of your project.

What is Go?

Go (a.k.a., Golang) is a programming language first developed at Google. It is a statically-typed language with syntax loosely derived from C, but with additional features such as garbage collection, type safety, some dynamic-typing capabilities, additional built-in types (e.g., variable-length arrays and key-value maps), and a large standard library.

Variants:

The golang images come in many flavors, each designed for a specific use case.

  • golang:<version>

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of. This tag is based off of buildpack-deps. buildpack-deps is designed for the average user of docker who has many images on their system. It, by design, has a large number of extremely common Debian packages. This reduces the number of packages that images that derive from it need to install, thus reducing the overall size of all images on your system.

  • golang:<version>-slim

This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run Go. Unless you are working in an environment where only the Go image will be deployed and you have space constraints, we highly recommend using the default image of this repository.

Notes:

  • Default working directory (WORKDIR) and $GOPATH is /go, Go projects should be copied there. If you want to copy your projects to different place, you need to set $GOPATH by yourself.

  • ARM Qemu and Go don't work together properly, so we highly recommend our users to build your Go projects on the device (only ARM devices, you do not need to do this for other platforms), not during build time. Otherwise, the build will potentially fail. You can have a script to build and run Go projects and use Docker CMD command to run it.
