Docker API

Dev Setup

The recommended way is to use the main Makefile that runs everything inside a container.

If you don't have or want to use Docker for building you need to make sure you have all the needed tools installed locally:

• go 1.14
• protoc
• go get github.com/golang/protobuf/protoc-gen-go@v1.4.1
• go get golang.org/x/tools/cmd/goimports
• go get github.com/golangci/golangci-lint/cmd/golangci-lint@v1.26.0

And then you can call the same make targets but you need to pass it the builder.Makefile (make -f builder.Makefile).

The new CLI delegates to the classic docker for default contexts ; delegation is done to com.docker.cli.

• make moby-cli-link will create a com.docker.cli link in /usr/local/bin if you don't already have it from Docker Desktop

Building the project

$ make

This will make the cli with all backends enabled. make cross on the other hand will cross-compile the cli without the example and local backend. We use make cross to build for our release, hence the exclusion of those backends. You can still cross-compile with all backends enabled: BUILD_TAGS=example,local make cross.

If you make changes to the .proto files, make sure to make protos to generate go code.

Tests

To run unit tests:

make test

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