Overview

This directory contains scripts that facilitate building and running gRPC tests for combinations of language/runtimes (known as matrix).

The setup builds gRPC docker images for each language/runtime and upload it to Google Container Registry (GCR). These images, encapsulating gRPC stack from specific releases/tag, are used to test version compatiblity between gRPC release versions.

Instructions for creating GCR images

  • Edit ./client_matrix.py to include desired gRPC release.
  • Run tools/interop_matrix/create_matrix_images.py. Useful options:
    • --git_checkout enables git checkout grpc release branch/tag.
    • --release specifies a git release tag. Make sure it is a valid tag in the grpc github rep.
    • --language specifies a language. For examle, To build all languages for all gRPC releases across all runtimes, do tools/interop_matrix/create_matrix_images.py --git_checkout --release=all.
  • Verify the newly created docker images are uploaded to GCR. For example:
    • gcloud beta container images list --repository gcr.io/grpc-testing shows image repos.
    • gcloud beta container images list-tags gcr.io/grpc-testing/grpc_interop_go1.7 show tags for a image repo.

Instructions for adding new language/runtimes*

  • Create new Dockerfile.template, build_interop.sh.template for the language/runtime under template/tools/dockerfile/.
  • Run tools/buildgen/generate_projects.sh to create corresponding files under tools/dockerfile/.
  • Add language/runtimes to client_matrix.py following existing language/runtimes examples.
  • Run tools/interop_matrix/create_matrix_images.py which will build and upload images to GCR. Unless you are also building images for a gRPC release, make sure not to set --gcr_tag (the default tag 'master' is used for testing).

*: Please delete your docker images at https://pantheon.corp.google.com/gcr/images/grpc-testing?project=grpc-testing afterwards. Permissions to access GrpcTesting project is required for this step.

Instructions for creating new test cases

  • Create test cases by running LANG=<lang> [RELEASE=<release>] ./create_testcases.sh. For example,
    • LANG=go ./create_testcases.sh will generate ./testcases/go__master, which is also a functional bash script.
    • LANG=go KEEP_IMAGE=1 ./create_testcases.sh will generate ./testcases/go__master and keep the local docker image so it can be invoked simply via ./testcases/go__master. Note: remove local docker images manually afterwards with docker rmi <image_id>.
  • Stage and commit the generated test case file ./testcases/<lang>__<release>.

Instructions for running test cases against a GCR image

  • Run test cases by specifying docker_image variable inline with the test case script created above. For example:
    • docker_image=gcr.io/grpc-testing/grpc_interop_go1.7:master ./testcases/go__master will run go__master test cases against go1.7 with gRPC release master docker image in GCR.

Note:

  • File path starting with tools/ or template/ are relative to the grpc repo root dir. File path starting with ./ are relative to current directory (tools/interop_matrix).
