Scaling Golang CI by Replacing actions/setup-go

The article discusses scaling Go language Continuous Integration (CI) by replacing actions/setup-go in GitHub Actions. The setup-go action is a popular action for setting up Go development environments in CI pipelines. However, it has some limitations, such as requiring a separate step to update the Go version, and can take up a significant amount of memory and time. The author of the blog post found that replacing actions/setup-go with a custom setup script can improve the performance and efficiency of Go CI pipelines. The custom script uses the go.mod file to automatically download and install the necessary Go version, and can be easily integrated into existing CI pipelines. This approach can help scale Go CI pipelines and reduce the time and resources required for testing and building Go projects.
