# Dockerfile for building the example client. To build the image, run the
# following command from grpc-go directory:
# docker build -t <TAG> -f examples/features/csm_observability/client/Dockerfile .

RUN apk --no-cache add curl

# Make a grpc-go directory and copy the repo into it.

COPY . .

# Build a static binary without cgo so that we can copy just the binary in the
# final image, and can get rid of the Go compiler and gRPC-Go dependencies.
