CRUD operations using ETCD

Problem Statement

The task was to create a full fledged application that is able to do CRUD with etcd and to integrate logger and config. Addons are implementation of a websocket and a router that can be used to handle grpc requests as well as http requests.

Prerequisites

1. golang
2. Docker
3. Setting up etcd container

installation

docker run -d --name etcd-server \
--publish 2379:2379 \
--publish 2380:2380 \
--env ALLOW_NONE_AUTHENTICATION=yes \
--env ETCD_ADVERTISE_CLIENT_URLS=http://etcd-server:2379 \
bitnami/etcd:latest

4. protobuf

installation

brew install protobuf

5. protoc-gen-go

installation

go get -u google.golang.org/protobuf/cmd/protoc-gen-go

go install google.golang.org/protobuf/cmd/protoc-gen-go

6. protoc-gen-go-grpc

installation

go get -u google.golang.org/grpc/cmd/protoc-gen-go-grpc

go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

Development

1. git clone https://github.com/gopay-bootcamp/crud-toy.git
2. cd crud-toy
3. go mod tidy

Running

Build the proto file -:

protoc --go_out=. --go_opt=paths=source_relative ./procProto/process.proto

protoc --go-grpc_out=. --go-grpc_opt=requireUnimplementedServers=false ./procProto/process.proto

To enable and disable Grpc server-:

• Go to the config file config.yml, find the field called grpc_enabled and set that to true or false as needed

To create the binaries -:

make build

To run the http server -:

_output/bin/server start

To run the grpc server -:

_output/bin/server grpcStart

To run the client -:

_output/bin/cli <command> <args>
