Building and Testing¶

Compile and Test Your Own Traefik!

You want to build your own Traefik binary from the sources? Let's see how.

Building¶

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.

make binary

This will create binaries for the Linux platform in the dist folder.

In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define DOCKER_NON_INTERACTIVE=true environment variable.

$ make binary
docker build -t traefik-webui -f webui/Dockerfile webui

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

$ ls dist/
traefik*

The following targets can be executed outside Docker by setting the variable IN_DOCKER to an empty string (although be aware that some of the tests might fail in that context):

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

ex:

IN_DOCKER= make test-unit

Method 2: Using `go`¶

Requirements:

go v1.16+
environment variable GO111MODULE=on

Source Directory

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

Environment

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:

GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/<yourusername>/go"
GORACE=""
## ... and the list goes on

Build Traefik¶

Once you've set up your go environment and cloned the source repository, you can build Traefik.

# Generate UI static files
make clean-webui generate-webui

# required to merge non-code components into the final binary,
# such as the web dashboard/UI
go generate

# Standard go build
go build ./cmd/traefik

You will find the Traefik executable (traefik) in the ~/go/src/github.com/traefik/traefik directory.

Testing¶

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/traefik/traefik/dist:/go/src/github.com/traefik/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/traefik/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 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

Check gocheck for more information.

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/traefik/traefik    0.004s

Integration tests must be run from the integration/ directory and require the -integration switch: $ cd integration && go test -integration ./....
