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.
## Step-by-step instructions for adding a new release to compatibility test
We have continuous nightly test setup to test gRPC backward compatibility between old clients and latest server. When a gRPC developer creates a new gRPC release, s/he is also responsible to add the just-released gRPC client to the nightly test. The steps are:
- Add (or update) an entry in ./client_matrix.py file to reference the github tag for the release.
- Build new client docker image(s). For example, for java release `v1.9.9`, do
- `tools/interop_matrix/create_matrix_images.py --git_checkout --release=v1.9.9 --language=java`
- Verify that the new docker image was built successfully and uploaded to GCR. For example,
- `gcloud beta container images list-tags gcr.io/grpc-testing/grpc_interop_java_oracle8`
- should show an image entry with tag `v1.9.9`.
- Verify the just-created docker client image would pass backward compatibility test (it should). For example,
- `gcloud docker -- pull gcr.io/grpc-testing/grpc_interop_java_oracle8:v1.9.9` followed by
- `docker_image=gcr.io/grpc-testing/grpc_interop_java_oracle8:v1.9.9 ./testcases/java__master`
- git commit the change and merge it to upstream/master.
- (Optional) clean up the tmp directory to where grpc source is cloned at `/export/hda3/tmp/grpc_matrix/`.
For more details on each step, refer to sections below.
## Instructions for creating GCR images
- Edit `./client_matrix.py` to include desired gRPC release.
- Run `tools/interop_matrix/create_matrix_images.py`. Useful options:

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`).
- Creating and referencing images in GCR require read and write permission to Google Container Registry path gcr.io/grpc-testing.
