Chapter 1. Go Toolset
Go Toolset is a Red Hat offering for developers on Red Hat Enterprise Linux (RHEL). It provides the Go programming language tools and libraries. Note that Go is alternatively known as golang.
Go Toolset is available as a module for RHEL 8 and as packages for RHEL 9 and 10.
1.1. Go Toolset components
The following components are available as a part of Go Toolset:
| Name | Version | Description |
|---|---|---|
| golang | 1.24 | A Go compiler. |
| delve | 1.24 | A Go debugger. |
1.2. Go Toolset compatibility
Go Toolset is available for Red Hat Enterprise Linux on the following architectures:
- AMD and Intel 64-bit (x86_64)
- 64-bit ARM (aarch64)
- IBM Power Systems, Little Endian (ppc64le)
- 64-bit IBM Z (s390x)
1.3. Installing Go Toolset
Complete the following steps to install Go Toolset, including all dependent packages.
Prerequisites
- All available Red Hat Enterprise Linux updates are installed.
Procedure
Install Go Toolset:
On RHEL 8, enter:
# yum module install go-toolsetOn RHEL 9 and 10, enter:
# dnf install go-toolset
1.4. Installing Go documentation
You can install documentation for the Go programming language on your local system.

golang-docspackage:On RHEL 8, enter:
# yum install golang-docsOn RHEL 9 and 10, enter:

Chapter 2. The Go compiler
2.1. Prerequisites
2.2. Setting up a Go workspace
Modern Go projects are built using modules. You can start with a single module and then optionally group multiple modules into a workspace to work on them simultaneously.
Procedure
Create a root directory for your projects, for example:
$ mkdir ~/go-projects/Change into the project directory:
$ cd ~/go-projects/Initialize a module:
Create a directory for your module:
$ mkdir <module_name>Change into the module’s directory:
$ cd <module_name>Initialize the module:
$ go mod init <module_name>This command creates a single-module project.
If you want to create multiple modules, repeat this step for every module.
If you want to work on multiple modules at the same time, create a multi-module workspace:
Change into the project directory:
$ cd ~/go-projects/Initialize a workspace to include multiple modules:
$ go work init <module_name_1> <module_name_n> ...

2.3. Compiling a Go program
You can compile your Go program using the Go compiler. The Go compiler creates an executable binary file as a result of compiling.
Prerequisites
- A Go workspace with configured modules.
Procedure
Compile the Go sources in the current directory:
$ go build .
2.4. Running a Go program
The Go compiler creates an executable binary file as a result of compiling. Complete the following steps to run your program.
Procedure
Use one of the following options to run your Go program:
To run an compiled program, enter:
$ ./<file_name>Replace
<file_name>with the name of your executable file.To compile the sources in the current directory and run the program in a single step, enter:
$ go run .
2.5. Installing compiled Go projects
You can download and install third-party Go projects from online resources to use their executable files and libraries in further Go projects. After installation, the executable files and libraries of the project are copied according to the directories in the Go workspace. Its dependencies are installed as well.
Prerequisites
- A Go workspace with configured modules.
Procedure
Install a Go project:
$ go install <go_project>
2.6. Downloading and installing Go projects
You can download and install third-party Go projects from online resources to use their executable files and libraries in further Go projects. After installation, the executable files and libraries of the project are copied according to the directories in the Go workspace. Its dependencies are installed as well.
Prerequisites
- A Go workspace with configured modules.
Procedure
To download and install a Go project, enter:
$ go install <third_party_go_project>Optional: For information on possible values of third-party projects, enter:
$ go help importpath

Chapter 3. The gofmt formatting tool
Instead of a style guide, the Go programming language uses the gofmt code formatting tool. gofmt automatically formats your code according to the Go layout rules.
3.1. Prerequisites
3.2. Formatting code
You can use the gofmt formatting tool to format code in a given path. When the path leads to a single file, the changes apply only to the file. When the path leads to a directory, all .go files in the directory are processed.
Procedure
To format your code in a given path, enter:
$ gofmt -w <code_path>Replace
<code_path>with the path to the code you want to format.NoteTo print the formatted code to standard output instead of writing it to the original file, omit the
-woption.
3.3. Previewing changes to code
You can use the gofmt formatting tool to preview changes done by formatting code in a given path. The output in unified diff format is printed to standard output.
Procedure
Show differences in your code in a given path:
$ gofmt -d <code_path>Replace
<code_path>with the path to the code you want to compare.
3.4. Simplifying code
You can use the gofmt formatting tool to simplify your code.
Procedure
To simplify code in a given path, enter:
$ gofmt -s -w <code_path>Replace
<code_path>with the path to the code you want to simplify.To apply the changes, enter:
$ gofmt -w <code_path>Replace
<code_path>with the path to the code you want to format.
3.5. Refactoring code
You can use the gofmt formatting tool to refactor your code by applying arbitrary substitutions.
Procedure
To refactor your code in a given path, enter:
$ gofmt -r -w <rewrite_rule> <code_path>Replace
<code_path>with the path to the code you want to refactor and<rewrite_rule>with the rule you want it to be rewritten by.To apply the changes, enter:
# gofmt -w <code_path>Replace
<code_path>with the path to the code you want to format.

Chapter 4. The Go race detector
Go Toolset includes the Go race detector, which is a tool of the Go standard library for finding race conditions. Note that the race detector has a significant runtime resource overhead.
4.1. Prerequisites
4.2. Using the Go race detector
Use the Go race detector to check your code for race conditions.
Procedure
Use the race detector:
# go build -race -o <output_file> <go_main_package>Replace
<output_file>with the name of your executable file and<go_main_package>with the name of the package you want to test.

Chapter 5. Container images with Go Toolset
You can build your own Go Toolset containers from either Red Hat Enterprise Linux container images or Red Hat Universal Base Images (UBI).
5.1. Red Hat Enterprise Linux Go Toolset container images contents
The Red Hat Enterprise Linux container images of Go Toolset contain the following packages:
| Component | Version | Package |
|---|---|---|
|
| 1.24 | go-toolset-1.24 |
5.2. Pulling the RHEL-based Go Toolset container image
Pull the container image from the Red Hat registry before running your container and performing actions.
Procedure
Pull the required image:
For an image based on RHEL 8, enter:
# podman pull registry.redhat.io/rhel8/go-toolsetFor an image based on RHEL 9, enter:
# podman pull registry.redhat.io/rhel9/go-toolsetFor an image based on RHEL 10, enter:
# podman pull registry.redhat.io/rhel10/go-toolset
5.3. Pulling the UBI-based Go Toolset container image
Pull the container image from the Red Hat registry before running your container and performing actions.
Procedure
Pull the required image:
For an image based on RHEL 8, enter:
# podman pull registry.access.redhat.com/ubi8/go-toolsetFor an image based on RHEL 9, enter:
# podman pull registry.access.redhat.com/ubi9/go-toolsetFor an image based on RHEL 10, enter:
# podman pull registry.access.redhat.com/ubi10/go-toolset
5.4. Creating a custom UBI-based container with Go Toolset
Go Toolset packages are part of the Red Hat Universal Base Images (UBIs) repositories, which means you can install Go Toolset as an addition to the base UBI container image. To keep the container image size small, install only individual packages instead of the entire Go Toolset.
Alternatively, you can install the UBI Go Toolset container image to access Go Toolset. For further information, see Pulling the UBI-based Go Toolset container image.
Prerequisites
- An existing container file. For information on creating Containerfiles, see the Content from docs.docker.com is not included.Dockerfile reference page.
Procedure
To create a container image containing Go Toolset, add the following to your container file:
For an image based on RHEL 8, enter:
FROM registry.access.redhat.com/ubi8/ubi:latest RUN yum module install -y go-toolset
For an image based on RHEL 9, enter:
FROM registry.access.redhat.com/ubi9/ubi:latest RUN yum install -y go-toolset
For an image based on RHEL 10, enter:
FROM registry.access.redhat.com/ubi10/ubi:latest RUN yum install -y go-toolset
