Docker API

Actions Status

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

Unit tests

make test

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

e2e tests

make e2e-local

This requires a local Docker Engine running

AZURE_TENANT_ID="xxx" AZURE_CLIENT_ID="yyy" AZURE_CLIENT_SECRET="yyy" make e2e-aci

This requires azure service principal credentials to login to azure. To get the values to be set in local environment variables, you can create a new service principal once you're logged in azure (with docker login azure)

az ad sp create-for-rbac --name 'MyTestServicePrincipal' --sdk-auth

Running the ACI e2e tests will override your local login, the service principal credentials use a token that cannot be refreshed automatically. You might need to run again docker login azure to properly use the command line after running ACI e2e tests.

You can also run a single ACI test from the test suite:

AZURE_TENANT_ID="xxx" AZURE_CLIENT_ID="yyy" AZURE_CLIENT_SECRET="yyy" make E2E_TEST=TestContainerRun e2e-aci

Release

To create a new release:

  • check that the CI is green on the main branch's commit you want to release
  • simply 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 (mac, win, linux) available for download.

Note: Linux binaries are not automatically copied to /docker/aci-integration-beta, if you want to make the linux binary publicly available, you'll need to manually create a release in aci-integration-beta and upload the binary. For Desktop integration, you need to make a PR in /docker/pinata and update the cli release number here
