### Building
|
|
|
|
You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build traefik. For changes to its dependencies, the `glide` dependency management tool and `glide-vc` plugin are required.
|
|
|
|
#### Method 1: 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 .
|

|
|
```
|
|
|
|
#### Method 2: Using `go`
|
|
|
|
###### Setting up your `go` environment
|
|
|
|
- You need `go` v1.7+
|
|
- It is recommended you clone Træfik into a directory like `~/go/src/github.com/containous/traefik` (This is the official golang workspace hierarchy, and will allow dependencies to resolve properly)
|
|
- This will allow your `GOPATH` and `PATH` variable to be set to `~/go` via:
|
|
```bash
|
|
$ export GOPATH=~/go
|
|
$ export PATH=$PATH:$GOPATH/bin
|
|
```
|
|
|
|
This can be verified via `$ go env`
|
|
- You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
|
|
- You need `go-bindata` to be able to use `go generate` command (needed to build) : `$ go get github.com/jteeuwen/go-bindata/...` (Please note, the ellipses are required)
|
|
|
|
#### Setting up `glide` and `glide-vc` for dependency management
|
|
|
|
- Glide is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
|
|
- Glide can be installed either via homebrew: `$ brew install glide` or via the official glide script: `$ curl https://glide.sh/get | sh`
|
|
- The glide plugin `glide-vc` must be installed from source: `go get github.com/sgotti/glide-vc`
|
|
|
|
If you want to add a dependency, use `$ glide get` to have glide put it into the vendor folder and update the glide manifest/lock files (`glide.yaml` and `glide.lock`, respectively). A following `glide-vc` run should be triggered to trim down the size of the vendor folder. The final result must be committed into VCS.
|
|
|
|
Dependencies for the integration tests in the `integration` folder are managed in a separate `integration/glide.yaml` file using the same toolset.
|
|
|
|
Care must be taken to choose the right arguments to `glide` when dealing with either main or integration test dependencies, or otherwise risk ending up with a broken build. For that reason, the helper script `script/glide.sh` encapsulates the gory details and conveniently calls `glide-vc` as well. Call it without parameters for basic usage instructions.
|
|
|
|
Here's a full example:
|
|
|
|
```bash
|
|
# install the new main dependency github.com/foo/bar and minimize vendor size
|
|
$ ./script/glide.sh get github.com/foo/bar
|
|
# install another dependency, this time for the integration tests
|
|
$ ( cd integration && ../script/glide.sh get github.com/baz/quuz )
|
|
# generate (Only required to integrate other components such as web dashboard)
|
|
$ go generate
|
|
# Standard go build
|
|
$ go build
|
|
# Using gox to build multiple platform
|
|
$ gox "linux darwin" "386 amd64 arm" \
|
|
-output="dist/traefik_{{.OS}}-{{.Arch}}" \
|
|
./cmd/traefik
|
|
# run other commands like tests
|
|
```
|
|
|
|
### Tests
|
|
|
|
##### Method 1: `Docker` and `make`
|
|
|
|
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 .
|
|
ok github.com/containous/traefik 0.005s coverage: 4.1% of statements
|
|
|
|
Test success
|
|
```
|
|
|
|
For development purposes, you can specify which tests to run by using:
|
|
```bash
|
|
# Run every tests in the MyTest suite
|
|
TESTFLAGS="-check.f MyTestSuite" make test-integration
|
|
|
|
# Run the test "MyTest" in the MyTest suite
|
|
TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
|
|
|
|
# Run every tests starting with "My", in the MyTest suite
|
|
TESTFLAGS="-check.f MyTestSuite.My" make test-integration
|
|
|
|
# Run every tests ending with "Test", in the MyTest suite
|
|
TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
|
|
```
|

|
|
##### Method 2: `go`
|
|
|
|
- Tests can be run from the cloned directory, by `$ go test ./...` which should return `ok` similar to:
|
|
```
|
|
ok _/home/vincent/src/github/vdemeester/traefik 0.004s
|
|
```
