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 Docker and Makefile

Run make with the binary target. This will create binaries for the Linux platform in the dist folder.

$ make binary
docker build -t traefik-webui -f webui/Dockerfile webui
Sending build context to Docker daemon  2.686MB

---> Making bundle: binary (in .)

$ ls dist/

The following targets can be executed outside Docker by setting the variable PRE_TARGET to an empty string (we don't recommend that):

  • test-unit
  • test-integration
  • validate
  • binary (the webUI is still generated by using Docker)


PRE_TARGET= make test-unit

Method 2: Using go


  • go v1.13+
  • environment variable GO111MODULE=on
  • go-bindata GO111MODULE=off go get -u

Source Directory

It is recommended that you clone Traefik into the ~/go/src/ directory. This is the official golang workspace hierarchy that will allow dependencies to be properly resolved.


Set your GOPATH and PATH variable to be set to ~/go via:

export GOPATH=~/go
export PATH=$PATH:$GOPATH/bin

For convenience, add GOPATH and PATH to your .bashrc or .bash_profile

Verify your environment is setup properly by running $ go env. Depending on your OS and environment, you should see an output similar to:

## ... and the list goes on

Build Traefik

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/

# Get go-bindata. (Important: the ellipses are required.)
GO111MODULE=off go get

# 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 ~/go/src/ directory.

Updating the templates

If you happen to update the provider's templates (located in /templates), you must run go generate to update the autogen package.


Method 1: Docker and make

Run unit tests using the test-unit target. Run integration tests using the test-integration target. Run all tests (unit and integration) using the test target.

$ 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/" "traefik-dev:your-feature-branch" ./script/ generate test-unit
---> Making bundle: generate (in .)
removed 'gen.go'

---> Making bundle: test-unit (in .)
+ go test -cover -coverprofile=cover.out .
ok   0.005s  coverage: 4.1% of statements

Test success

For development purposes, you can specify which tests to run by using (only works the test-integration target):

# 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

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 -integration switch: $ cd integration && go test -integration ./....
