BUILDING.md

Prerequisites

• Windows:
  • Docker Desktop
  • make
• macOS:
  • Docker Desktop
  • make
• Linux:
  • Docker 19.03 or later
  • make

Building the CLI

Once you have the prerequisites installed, you can build the CLI using:

make

This will output a CLI for your host machine in ./bin.

You will then need to make sure that you have the existing Docker CLI in your PATH with the name com.docker.cli.

You can statically cross compile the CLI for Windows, macOS, and Linux using the cross target.

Updating the API code

The API provided by the CLI is defined using protobuf. If you make changes to the .proto files in protos/, you will need to regenerate the API code:

make protos

Unit tests

To run all of the unit tests, run:

make test

If you need to update a golden file simply do go test ./... -test.update-golden.

End to end tests

Local tests

To run the local end to end tests, run:

make e2e-local

Note that this requires the CLI to be built and a local Docker Engine to be running.

ECS tests

To run the end to end ECS tests, you will need to have an AWS account and have credentials for it in the ~/.aws/credentials file.

You can then use the e2e-ecs target:

TEST_AWS_PROFILE=myProfile TEST_AWS_REGION=eu-west-3 make e2e-ecs

Releases

To create a new release:

• Check that the CI is green on the main branch for commit you want to release
• Create a new tag of the form vx.y.z, following existing tags, and push the tag

Pushing the tag will automatically create a new release and make binaries for Windows, macOS, and Linux available for download on the releases page.
