Building and Testing

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

Building

To build Traefik Mesh from the sources you need either Docker and make, or Go.

With Docker and make

Traefik Mesh can be built from the sources by using the make command. This will create a binary for the Linux platform in the dist directory and a Docker image:

$ make
#[...]
Successfully tagged traefik/mesh:latest
docker run --name=build -t "traefik/mesh:latest" version
version:
 version     : d6947526
 commit      : d6947526
 build date  : 2022-03-16_03:19:22PM
 go version  : go1.19
 go compiler : gc
 platform    : linux/amd64
#[...]

$ ls dist/
traefik-mesh

Note

The default make target invokes the clean, check, test and build targets.

With Go

Requirements:

  • Go v1.19+
  • Environment variable GO111MODULE=on

One your Go environment is set up, you can build Traefik Mesh from the sources by using the go build command. The Go compiler will build an executable for your platform.

$ go build -o dist/traefik-mesh cmd/mesh/mesh.go
$ ./dist/traefik-mesh version
version:
 version     : dev
 commit      : I don't remember exactly
 build date  : I don't remember exactly
 go version  : go1.19
 go compiler : gc
 platform    : linux/amd64

Testing

With Docker and make

Run unit tests by using the test target:

$ make test
docker build --tag "traefik/mesh:test" --target maker --build-arg="MAKE_TARGET=local-test" /home/user/traefik-mesh/
#[...]

Run the integration tests by using the test-integration target. For development purposes, you can specify which tests to run by using the TESTFLAGS environment variable (only works with 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

With Go

Run the unit tests by using the go test command:

$ go test -v ./...

Run the integration tests in the integration directory by using the go test ./integration -integration command:

$ go test -v ./integration -integration -check.f CoreDNSSuite
#[...]
OK: 2 passed
--- PASS: Test (161.20s)
PASS

Important

Before running the integration tests, build the Traefik Mesh Docker image. Check out the Building section for more details.
