Building and Testing¶
Compile and Test Your Own Traefik!
So you want to build your own Traefik binary from the sources? Let's see how.
You need either Docker and
make (Method 1), or
go (Method 2) in order to build Traefik.
For changes to its dependencies, the
dep dependency management tool is required.
Method 1: Using
Run make with the
This will create binaries for the Linux platform in the
$ make binary docker build -t traefik-webui -f webui/Dockerfile webui Sending build context to Docker daemon 2.686MB Step 1/11 : FROM node:8.15.0 ---> 1f6c34f7921c [...] Successfully built ce4ff439c06a Successfully tagged traefik-webui:latest [...] docker build -t "traefik-dev:4475--feature-documentation" -f build.Dockerfile . Sending build context to Docker daemon 279MB Step 1/10 : FROM golang:1.13-alpine ---> f4bfb3d22bda [...] Successfully built 5c3c1a911277 Successfully tagged traefik-dev:4475--feature-documentation docker run -e "TEST_CONTAINER=1" -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -e VERBOSE -e VERSION -e CODENAME -e TESTDIRS -e CI -e CONTAINER=DOCKER -v "/home/ldez/sources/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:4475--feature-documentation" ./script/make.sh generate binary ---> Making bundle: generate (in .) removed 'autogen/genstatic/gen.go' ---> Making bundle: binary (in .) $ ls dist/ traefik*
The following targets can be executed outside Docker by setting the variable
PRE_TARGET to an empty string (we don't recommend that):
binary(the webUI is still generated by using Docker)
PRE_TARGET= make test-unit
Method 2: Using
- environment variable
GO111MODULE=off go get -u github.com/containous/go-bindata/...
It is recommended that you clone Traefik into the
This is the official golang workspace hierarchy that will allow dependencies to be properly resolved.
PATH variable to be set to
export GOPATH=~/go export PATH=$PATH:$GOPATH/bin
For convenience, add
PATH to your
Verify your environment is setup properly by running
$ go env.
Depending on your OS and environment, you should see an output similar to:
GOARCH="amd64" GOBIN="" GOEXE="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOOS="linux" GOPATH="/home/<yourusername>/go" GORACE="" ## ... and the list goes on
Once you've set up your go environment and cloned the source repository, you can build Traefik.
Beforehand, you need to get
go-bindata (the first time) in order to be able to use the
go generate command (which is part of the build process).
cd ~/go/src/github.com/containous/traefik # Get go-bindata. (Important: the ellipses are required.) GO111MODULE=off go get github.com/containous/go-bindata/... # Let's build # generate # (required to merge non-code components into the final binary, such as the web dashboard and the provider's templates) go generate # Standard go build go build ./cmd/traefik
You will find the Traefik executable (
traefik) in the
Updating the templates¶
If you happen to update the provider's templates (located in
/templates), you must run
go generate to update the
Run unit tests using the
Run integration tests using the
Run all tests (unit and integration) using the
$ 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/user/go/src/github/containous/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 (only works the
# 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
Unit tests can be run from the cloned directory using
$ go test ./... which should return
ok, similar to:
ok _/home/user/go/src/github/containous/traefik 0.004s
Integration tests must be run from the
integration/ directory and require the
$ cd integration && go test -integration ./....
