Simple redis client written in Go. You can interact (set, get) either with local redis running in docker or the Azure Cache for Redis (deployed using terraform).
michalsw/redis-client:latest
While connecting to Redis by default there is no password set in redis-client. If you want to pass access key (password) use env REDIS_PASS. If TLS is required like in Azure use env REDIS_TLS.
Use make to get all details and run specific command.
$ make help
GET /red/ping
POST /red/setuser
GET /red/getuser/{id}
GET /red/home
# deploy 'redis'
docker run --rm -d --name redis -p 6379:6379 redis
# run 'redis-client'
> go
make go-run
> docker
REDIS_HOST=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' redis)
REDIS_HOST=$REDIS_HOST make docker-run
# POST
curl -i -X POST -d '{"name":"mi","age":10}' localhost:8080/red/setuser
curl -i -X POST -d '{"name":"mo","age":20}' localhost:8080/red/setuser
# GET
curl -XGET localhost:8080/red/ping
PONG
curl -XGET -s localhost:8080/red/getuser/1 | jq
{
"name": "mi",
"age": 10
}
curl -XGET -s localhost:8080/red/getuser/2 | jq
{
"name": "mo",
"age": 20
}
Here you have some example how to create a Python app that uses Azure Cache for Redis.
Don't forget to log in to Azure!
## login
az login

User is connecting to Redis-client to connect to Redis-cache.
redis-client is a frontend-service (deployed using App Service).
redis is a backend-service (deployed using ACI in private VNet).
$ az login
$ make azure-rg
Deploy redis-client webapp
Create the private VNet
$ make azure-vnet-create
Deploy redis using ACI in the private VNet
$ make azure-redis-vnet
Configure VNet integration
More details you can find here.
Select Add VNet:
Specify Subnet Address Block:
Configure redis-client (ENV vars)
$ REDISIP=$(az container show --resource-group redisrg --name redis --query ipAddress.ip --output tsv)
