docker-library/golang: Source for the Docker Official golang Image

What docker-library/golang packages

docker-library/golang addresses image packaging for developers who want Go available inside a Docker container. It is the Git repository behind the Docker Official Image named `golang`. The repository explicitly distinguishes that image from any similarly named image offered by Go upstream, so the Docker image is not an official Go compiler distribution merely because it contains the Go toolchain.

The audience has two distinct sides. Application developers need an understandable place to inspect and obtain the image. Image contributors need the source templates and generation scripts used to produce its version-specific definitions. This repository serves the second role more directly. It contains versioned directories for Go `1.26` and `1.27`, a `tip` directory, version metadata and shell-based maintenance scripts. Those names indicate an organized image build source rather than an application library intended to be imported by Go code.

The Docker Hub page is presented as the complete user-facing readme for the image. Contribution guidance and issue information are also directed there. By contrast, this Git repository's README is a generated stub that explains where the longer documentation and the current image definition live. That separation matters when diagnosing a discrepancy: a reader should not assume that every runtime instruction is implemented or documented here.

Image generation structure and source-of-truth boundaries

The repository layout shows a template-driven packaging process. `Dockerfile-linux.template` is the Linux definition, while `Dockerfile-windows-nanoserver.template` and `Dockerfile-windows-servercore.template` provide Windows image bases. Version-specific directories under `1.26/`, `1.27/` and `tip/` hold the generated or version-applied Dockerfile content implied by the repository structure. The exact substitution syntax is not documented in the README, so it would be unsafe to reconstruct the generation process from filenames alone.

Several scripts expose the automation boundary. `apply-templates.sh` appears to apply Dockerfile templates, `versions.sh` contains version-related shell logic, `update.sh` handles an update operation, and `generate-stackbrew-library.sh` generates separate library metadata. `versions.json` records version data used by the surrounding tooling. These filenames support the conclusion that image maintenance is script-assisted, but the README does not document their individual command-line interfaces.

There are also three official images repositories with different roles. This repository contains the `golang` image source. The `library/golang` file in `docker-library/official-images` is identified as the current source of truth for the published image. The user-facing description is generated and maintained in the `golang` directory of `docker-library/docs`. As a result, a merged change here is not necessarily the same thing as a change already visible on Docker Hub. The README points to the official-images change lifecycle for the explanation of that delay.

Finding the image and completing a first container use

The repository does not provide installation commands for developers, so there is no documented `docker pull`, `docker run` or Compose example that can be reproduced faithfully from it. The installation path begins on the Docker Hub page for `_/golang`, which the README calls the full readme for how to use the image. A first-time user should consult that page for the current pull command, available tags and usage example rather than treating this source repository as an executable package.

After obtaining the image from the documented Docker Hub source, the first practical task depends on the selected tag. This repository's version directories show support for release lines `1.26` and `1.27`, plus a `tip` directory, but they do not establish which image tags are currently published or how a particular tag is built. The correct tag must therefore be verified on Docker Hub before any build or container command is created.

For source-based inspection, start by comparing `Dockerfile-linux.template` with the Linux Dockerfile in the relevant version directory, and do the same for either Windows template when that platform matters. This does not require running the project. It gives an image maintainer a concrete way to trace how a documented base and version definition may be applied. The README does not document rollback procedures, image signing, digest usage, architecture selection or supported host platforms, so those points cannot be answered from this repository alone.

Linux and Windows definitions have different maintenance surfaces

The presence of three templates means this source is not limited to one operating-system family. Linux has a dedicated template, while Windows is represented by separate Nano Server and Server Core templates. A change intended for all published variants may therefore need review against different template inputs. The top-level repository structure makes that platform split visible even though the README does not explain feature parity or runtime behavior.

This arrangement is useful for packaging consistency because the named templates provide identifiable places to inspect platform-specific changes. It also creates an adoption constraint for contributors: changing one template may not produce equivalent image definitions across the others. The README does not state whether Windows and Linux tags are published in lockstep, whether both Windows variants are included for every Go version, or how `tip` relates to stable version directories.

The distinction between build and use is important here. This repository can describe how Dockerfiles are assembled, but the image itself is consumed through Docker Hub. Developers looking for compiler flags, module-cache behavior, shell defaults or a recommended production layout should use the Docker Hub documentation. Contributors looking for generation behavior should remain in this repository and the related `docker-library/docs` and `docker-library/official-images` repositories.

Maintenance activity, releases, and upgrade handling

The repository is not archived, and its last push was on 2026-10-12. That supports describing it as recently changed, but it does not establish a release cadence or guarantee that every Go version directory receives immediate attention. The repository has no GitHub releases. Consumers therefore cannot use GitHub release tags here as the package-update signal.

Image publication and GitHub releases are separate concepts for this project. The README says the current definition for the Docker Official Image is the `library/golang` file in `docker-library/official-images`, while Docker Hub serves the published image and full user documentation. The README does not document an upgrade command, automatic update policy, breaking-change process or rollback procedure.

The BSD-3-Clause license applies to this repository. That identifies the stated licensing basis for the packaging source, but it is not evidence about the license of every Go distribution, downloaded tool, base-image layer or container produced from it. Organizations reviewing adoption should inspect the relevant Dockerfile inputs and published image metadata if they need terms beyond this repository's own license.

How this repository differs from consuming a normal Go image

The practical alternative to cloning or modifying docker-library/golang is to use the published `golang` Official Image from Docker Hub directly. That approach moves the developer from image source maintenance to image consumption. Docker Hub supplies the full usage readme, while `docker-library/official-images/library/golang` is the documented source of truth for the current published image. This repository remains relevant when the task is to inspect or contribute to how the image definition is generated.

A second alternative is sourcing `golang` from Go upstream, but this repository explicitly warns readers not to confuse its Docker Official Image with an official `golang` image provided by Go upstream. The README does not describe how that upstream distribution is packaged, so the defensible comparison is limited: consumers should choose according to the publisher and documentation they intend to trust, rather than assuming that matching image names indicate identical provenance.

For ordinary application work, generating templates or editing version directories adds maintenance that has no benefit. For image contribution work, relying only on Docker Hub usage instructions would omit the generation source. The right path follows the task: consume from Docker Hub, or modify the packaging repository and coordinate through the documented official-images workflow.

Editorial conclusion

Developers who want a Docker-packaged Go toolchain should start with the Docker Hub image page and confirm the selected tag before building. Contributors should not adopt or modify this repository as an application dependency. First verify whether the intended source of truth is this generation repository, the `library/golang` file in `docker-library/official-images`, or the generated documentation in `docker-library/docs`.
