Golang Template Project

About the project

The template is used to create golang project. All golang projects must follow the conventions in the template. Calling for exceptions must be brought up in the engineering team.

API docs

The template doesn't have API docs. For web service, please include API docs here, whether it's auto-generated or hand-written. For auto-generated API docs, you can also give instructions on the build process.

Design

The template follows project convention doc.

Status

The template project is in alpha status.

A brief description of the layout:

  • .github has two template files for creating PR and issue. Please see the files for more details.
  • .gitignore varies per project, but all projects need to ignore bin directory.
  • .golangci.yml is the golangci-lint config file.
  • Makefile is used to build the project. You need to tweak the variables based on your project.
  • CHANGELOG.md contains auto-generated changelog information.
  • OWNERS contains owners of the project.
  • README.md is a detailed description of the project.
  • bin is to hold build outputs.
  • cmd contains main packages, each subdirectory of cmd is a main package.
  • build contains scripts, yaml files, dockerfiles, etc, to build and package the project.
  • docs for project documentations.
  • hack contains scripts used to manage this repository, e.g. codegen, installation, verification, etc.
  • pkg places most of project business logic and locate api package.
  • release chart for production deployment.
  • test holds all tests (except unit tests), e.g. integration, e2e tests.
  • third_party for all third party libraries and tools, e.g. swagger ui, protocol buf, etc.
  • vendor contains all vendored code.

Notes

  • Makefile MUST NOT change well-defined command semantics, see Makefile for details.
  • Every project MUST use dep for vendor management and MUST checkin vendor direcotry.
  • cmd and build MUST have the same set of subdirectories for main targets
    • For example, cmd/admin,cmd/controller and build/admin,build/controller.
    • Dockerfile MUST be put under build directory even if you have only one Dockerfile.
