grpc-bookstore

Simple Bookstore CRUD service using gRPC and mongoDB

Quickstart

Start mongoDB server using docker-compose

docker-compose up -d

Check if the server is running by docker-compose ps

docker-compose ps

NAME                         IMAGE               COMMAND                  SERVICE             CREATED             STATUS              PORTS
grpc-bookstore-db-client-1   mongo-express       "tini -- /docker-ent…"   db-client           5 minutes ago       Up 11 seconds       0.0.0.0:8081->8081/tcp
mongo-server                 mongo               "docker-entrypoint.s…"   db                  5 minutes ago       Up 12 seconds       0.0.0.0:27017->27017/tcp

Setup .env file where MONGO_IMAGE is defined like this:

cat << EOF | tee .env
MONGO_IMAGE="mongodb://mongoadmin:secret@localhost:27017/"
EOF

note: you can simply copy .env.example on the same directory

Finally run gRPC server

 go run main.go 

Expected output would be like this

Connecting to MongoDB...
Connected to Mongodb
Starting Listener...
Bookstore Server Started...

After the test, shutdown the mongo server

docker-compose down

Testing the bookstore server

PostBook request for the endpoint 0.0.0.0:9090:
