protocachecli is a command-line client for interacting with the cache server.

protocachecli -host localhost -port 50051 set foo bar
protocachecli -host localhost -port 50051 get foo
protocachecli -host localhost -port 50051 del foo
protocachecli -host localhost -port 50051 clear

If the value contains binary or non-UTF-8 data, it will be shown in base64 format.

protocachecli --help

grpcurl -plaintext localhost:50051 list

grpcurl -plaintext localhost:50051 list cache.CacheService

make test         # Run all tests
make test-e2e     # Run E2E tests
make bench        # Run benchmarks

You can build and run Protocache via Docker.

make docker-build

This uses the image name: patrostkowski/protocache

make docker-run

This runs the server and exposes port 50051 on your local machine.
