cloner

This is a CLI that makes git clone simpler with an optional config to clone a given URL in a location for all of your git projects based on the host.

Why cloner?

  • You don't need to change to the directory where your github repos are located.
  • The base git repo will be based on the host, so they all are on the same place.
  • Commands are idempotent
    • For repeated repos, you must use the force option
cloner local -r https://github.com/comsysto/redis-locks-with-grafana
cloner local --repo git@github.com:marcellodesales/alpine-git-hub-docker-image.git
cloner local -r https://github.com/intuit/intuit-spring-cloud-config-inspector
cloner local -r git@github.com:intuit/unmazedboot
cloner local -r https://gitlab.com:supercash/services/sms-gateway-service.git
cloner local -r https://github.com/comsysto/redis-locks-with-grafana -f

ATTENTION: Assuming all defaults, of the clone location to ~/dev, the cloned and the private key being ~/.ssh/id_rsa. See below the options to the CLI.

Config

  • ~/.cloner.yaml git.cloneBaseDir: as the location for base git host dirs
version: 1.0
git:
  cloneBaseDir: ~/dev

When the CLI runs, it will create the dirs git.cloneBaseDir/git.host/git.org/git.repo

NOTE: Gitlab's and other hosts may be located in deeper folders.

Options

  • Just run the help to see the current options
cloner local --help
Clones a given git repo URL

Usage:
  cloner local [flags]

Flags:
  -f, --force               Forces cloning by deleting existing dir
  -h, --help                help for git
  -k, --privateKey string   The private key associated to the public key to clone 'git@' repos
  -r, --repo string         The repo URL to clone

Global Flags:
      --cloner string      Config file (default is $HOME/.cloner.yaml) (default "cloner")
  -v, --verbosity string   Log level (debug, info, warn, error, fatal, panic (default "info")

Development

Design

The design now is as follows:

            +-----+       +-----+      +------+
main +----->+ CMD +------>+ API +----->+ UTIL |
            +--+--+       +-----+      +------+
               ^
               |      +--------+
               +------+ CONFIG |
                      +--------+
  • CMD: CLI implementation using Cobra
  • CONFIG: Yaml configuration using Viper
  • API: Abstraction of services that implement capabilities
  • UTIL: Utility functions serving the API services

Tests

  • Look at the scenarios of the CLI in the tests
    • Tests at cmd/git_test.go
make test

Binaries

You can use Golang locally to build a local executable as follows (MacOS). The Github Actions CI build-develop implements the steps below, publishing binary artifacts at every commit under the develop branch.

$ make local
  • The local build will be available at dist/cloner-darwin-local

Other binary versions are available at the Artifacts section of the build-develop Github Actions. If you want to build locally, here's what you need to do:

Requirement: install the following:

  • docker
  • build tools

Run the following commands:

make dist

You should get the CLI binaries in different platforms-architectures

The CLI will print the help

ATTENTION: Make sure to select the proper binary for your current host!

$ ./dist/cloner-darwin-amd64

Remote Debug

$ docker-compose -f debug.docker-compose.yaml up
Recreating cloner_cli-debug_1 ... done
Attaching to cloner_cli-debug_1
cli-debug_1  | API server listening at: [::]:40000
  • For example, open Goland and use a Go Remote debug instance with port 40000.

Bug Reports & Feature Requests

Please use the issue tracker to report any bugs or file feature requests.

Social Coding and Contributing

  1. Create an issue to discuss about your idea
  2. [Fork it] (https://github.com/marcellodesales/cloner/fork)
  3. Create your feature branch (git checkout -b feature/my-new-feature)
  4. Commit your changes (git commit -am 'feature x: Add some capability')
  5. Push to the branch (git push origin feature/my-new-feature)
  6. Create a new Pull Request
  7. Profit! ✅

Our Gitflow is as follows:

  • develop: CI that runs all builds and generate binaries.
    • Target your PR here.
  • master: CD that creates a new release based on a TAG
    • Performed from PRs from develop
    • Publishes latest binary version from develop

Releases

Requires make and docker for a dockerized build and cross-compilation for Golang. We can run the same exact script on local host or in a CI environemtn. See our Github Action release-master, which runs at every PR merge to the master branch.

ATTENTION: Make sure to have a Github token with write permissions to the repo

  • Initial releases MUST have the code fully pushed to the repo
  • Git with versions are created in the format of yy.mm.#
    • Where, # is incremented at each release automatically.
$ make release PUBLISH_GITHUB_TOKEN=6100**********dbeb326
