Requirements

• Terraform 0.10.x
• Go 1.13.x (to build the provider plugin)

Building The Provider

Clone repository to: $GOPATH/src/github.com/terraform-providers/terraform-provider-docker

$ mkdir -p $GOPATH/src/github.com/terraform-providers; cd $GOPATH/src/github.com/terraform-providers
$ git clone [email protected]:terraform-providers/terraform-provider-docker

Enter the provider directory and build the provider

$ cd $GOPATH/src/github.com/terraform-providers/terraform-provider-docker
$ make build

Developing the Provider

If you wish to work on the provider, you'll first need the latest version of Go installed on your machine (currently 1.13). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH (note that we typically test older versions of golang as long as they are supported upstream, though we recommend new development to happen on the latest release).

To compile the provider, run make build. This will build the provider and put the provider binary in the $GOPATH/bin directory.

$ make build
...
$ $GOPATH/bin/terraform-provider-docker
...

In order to test the provider, you can simply run make test.

$ make test

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create a local registry which will be deleted afterwards.

$ make testacc

In order to run only single Acceptance tests, execute the following steps:

# setup the testing environment
$ make testacc_setup

# run single tests
TF_LOG=INFO TF_ACC=1 go test -v ./docker -run ^TestAccDockerImage_data_private_config_file$ -timeout 360s

# cleanup the local testing resources
$ make testacc_cleanup

In order to extend the provider and test it with terraform, build the provider as mentioned above with

$ make build
# or a specific version
$ go build -o terraform-provider-docker_v1.2.0_x4

Remove an explicit version of the provider you develop, because terraform will fetch the locally built one in $GOPATH/bin

provider "docker" {
  # version = "~> 0.1.2"
  ...
}

Don't forget to run terraform init each time you rebuild the provider. Check here for a more detailed explanation.

You can check the latest released version of a provider at https://releases.hashicorp.com/terraform-provider-docker/.

Developing on Windows

You can build and test on Widows without make. Run go install to build and Scripts\runAccTests.bat to run the test suite.

Continuous integration for Windows is not available at the moment due to lack of a CI provider that is free for open source projects and supports running Linux containers in Docker for Windows. For example, AppVeyor is free for open source projects and provides Docker on its Windows builds, but only offers Linux containers on Windows as a paid upgrade.
