### Building
|
||
|
||
You need either [Docker](https://github.com/docker/docker) and `make`, or `go` and `glide` in order to build traefik.
|
||
|
||
#### Setting up your `go` environment
|
||
|
||
- You need `go` v1.5
|
||
- You need to set `export GO15VENDOREXPERIMENT=1` environment variable
|
||
- You need `go-bindata` to be able to use `go generate` command (needed to build) : `go get github.com/jteeuwen/go-bindata/...`.
|
||
- If you clone Træfɪk into something like `~/go/src/github.com/traefik`, your `GOPATH` variable will have to be set to `~/go`: export `GOPATH=~/go`.
|
||
|
||
#### Using `Docker` and `Makefile`
|
||
|
||
You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder.
|
||
|
||
```bash
|
||
$ make binary
|
||
docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .

|
||
|

$ ls dist/
|
||
traefik*
|
||
```
|
||
|
||
#### Using `glide`
|
||
|
||
The idea behind `glide` is the following :
|
||
|
||
- when checkout(ing) a project, **run `glide up --quick`** to install
|
||
(`go get …`) the dependencies in the `GOPATH`.
|
||
- if you need another dependency, import and use it in
|
||
the source, and **run `glide get github.com/Masterminds/cookoo`** to save it in
|
||
`vendor` and add it to your `glide.yaml`.
|
||
|
||
```bash
|
||
$ glide up --quick
|
||
# generate
|
||
$ go generate
|
||
# Simple go build
|
||
$ go build
|
||
# Using gox to build multiple platform
|
||
$ gox "linux darwin" "386 amd64 arm" \
|
||
-output="dist/traefik_{{.OS}}-{{.Arch}}"
|
||
# run other commands like tests
|
||
$ go test ./...
|
||
ok _/home/vincent/src/github/vdemeester/traefik 0.004s
|
||
```
|
||
|
||
### Tests
|
||
|
||
You can run unit tests using the `test-unit` target and the
|
||
integration test using the `test-integration` target.
|
||
|
||
```bash
|
||
$ make test-unit
|
||
docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
|
||
# […]
|
||
docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/vincent/src/github/vdemeester/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
|
||
---> Making bundle: generate (in .)
|
||
removed 'gen.go'
|
||
|
||
---> Making bundle: test-unit (in .)
|
||
+ go test -cover -coverprofile=cover.out .
|
||
