Google Cloud Container Builder Local Builder
Local Builder runs Google Cloud Container Builder builds locally, allowing easier debugging, execution of builds on your own hardware, and integration into local build and test workflows.
Prerequisites
- gcloud
- docker
- go (if you build the tool yourself)
If the build needs to access a private GCR registry, install and configure the Docker credential helper for GCR users.
The local builder uses gcloud information to set up a spoofed metadata server, so you have to set the project:
gcloud config set project my-project
Download the binary
The latest binaries are available in a GCS bucket.
First check the latest tag on the releases page.
gsutil cp gs://container-builder-local/container-builder-local_{linux,darwin}_{386,amd64}-v<enter_tag> .
chmod +x container-builder-local_{linux,darwin}_{386,amd64}-v<enter_tag>
For example, to run a build on linux 386 with the v0.0.1 release:
gsutil cp gs://container-builder-local/container-builder-local_linux_386-v0.0.1 .
chmod +x container-builder-local_linux_386-v0.0.1
To run a build:
./container-builder-local_{linux,darwin}_{386,amd64}-v<enter_tag> --dryrun=false --config=path/to/cloudbuild.yaml path/to/code
Developing Local Builder
To build and develop Local Builder, you need a working Go environment.
Run the following commands to install the tool:
go get github.com/GoogleCloudPlatform/container-builder-local
go install github.com/GoogleCloudPlatform/container-builder-local
To run a build:
./bin/container-builder-local --dryrun=false --config=path/to/cloudbuild.yaml path/to/code
To run the tests (without the vendored libraries):
go test $(go list github.com/GoogleCloudPlatform/container-builder-local/... | grep -v vendor)
Limitations
- Only one build can be run at a time on a given host.
- The tool doesn't work on Windows yet, PR welcome.
