# Development Guide

## Building Kompose

Read about building kompose [here](https://github.com/kubernetes/kompose#development-and-building-of-kompose).

## Workflow

### Fork the main repository

1. Go to https://github.com/kubernetes/kompose
2. Click the "Fork" button (at the top right)

### Clone your fork

The commands below require that you have `$GOPATH`. We highly recommended you put the Kompose code into your `$GOPATH`.

```console
git clone https://github.com/$YOUR_GITHUB_USERNAME/kompose.git $GOPATH/src/github.com/kubernetes/kompose
cd $GOPATH/src/github.com/kubernetes/kompose
git remote add upstream 'https://github.com/kubernetes/kompose'
```

### Create a branch and make changes

```console
git checkout -b myfeature
# Make your code changes
```

### Keeping your development fork in sync

```console
git fetch upstream
git rebase upstream/main
```

Note: If you have write access to the main repository at github.com/kubernetes/kompose, you should modify your git configuration so that you can't accidentally push to upstream:

```console
git remote set-url --push upstream no_push
```

### Committing changes to your fork

```console
git commit
git push -f origin myfeature
```

### Creating a pull request

1. Visit https://github.com/$YOUR_GITHUB_USERNAME/kompose.git
2. Click the "Compare and pull request" button next to your "myfeature" branch.
3. Check out the pull request process for more details

## Go Modules and dependency management

Kompose uses [Go Modules](https://github.com/golang/go/wiki/Modules) to manage dependencies.
If you want to introduce changes to dependencies, please ensure that `go.mod` and `go.sum` are updated properly.

##### Updating Kubernetes and OpenShift

Kubernetes version depends on what version is OpenShift using.
OpenShift is using forked Kubernetes to carry some patches.
Currently, it is not possible to use a different Kubernetes version from the version that OpenShift uses.
(for more see comments in `go.mod`)

### Adding CLI tests

[Kompose CLI tests](https://github.com/kubernetes/kompose/tree/main/script/test/cmd) run `kompose convert` with compose files, and cross-check the k8s and OpenShift artifacts generated with the template files.

To generate CLI tests, please run `make gen-cmd`.

### CI

For Kompose, we use numerous CI's:

- [TravisCI](https://travis-ci.org/kubernetes/kompose): Unit and CLI tests
- [SemaphoreCI](https://semaphoreci.com/cdrage/kompose-2): Integration / cluster tests
- [Fabric8CI](http://jenkins.cd.k8s.fabric8.io/): Secondary integration tests / future cluster tests
