Redis client application

An example application that reads a key from Redis, increments it and writes it back to Redis.

cd .\storage\redis\applications\client\

# start go dev environment
docker run -it -v ${PWD}:/go/src -w /go/src --net redis -p 80:80 golang:1.14-alpine

go build client.go
# start the app
./client

# build the container
docker build . -t aimvector/redis-client:v1.0.0

Run our application

cd .\storage\redis\applications\client\
docker build . -t aimvector/redis-client:v1.0.0

docker run -it --net redis `
-e REDIS_HOST=redis `
-e REDIS_PORT=6379 `
-e REDIS_PASSWORD="SuperSecretSecureStrongPass" `
-p 80:80 `
aimvector/redis-client:v1.0.0
