Running Python scripts via Docker

• RocksDB native - https://github.com/facebook/rocksdb/blob/master/INSTALL.md
• gRPC Docker - https://github.com/grpc/grpc-docker-library/tree/master/1.4/python

OR

Create a Docker image using this example.

• Create a Docker network so that each container can connect to the host under the fixed IP 192.168.0.1.

docker network create -d bridge --subnet 192.168.0.0/24 --gateway 192.168.0.1 dockernet

• Run the server and client containers.

# Generate Stub for client and server
docker run -it --rm --name grpc-tools -v "$PWD":/usr/src/myapp -w /usr/src/myapp ubuntu-python3.6-rocksdb-grpc:1.0 python3.6 -m grpc.tools.protoc -I. --python_out=. --grpc_python_out=. datastore.proto


# Server
docker run -p 3000:3000 -it --rm --name lab1-server -v "$PWD":/usr/src/myapp -w /usr/src/myapp ubuntu-python3.6-rocksdb-grpc:1.0 python3.6 server.py

# Client
docker run -it --rm --name lab1-client -v "$PWD":/usr/src/myapp -w /usr/src/myapp ubuntu-python3.6-rocksdb-grpc:1.0 python3.6 client.py 192.168.0.1

Expected Output on Client

Client is connecting to Server at 192.168.0.1:3000...
