Not able to connect to redis service

[sangee2004]

Steps to reproduce the problem:

1. Deploy redis app using image ghcr.io/acorn-io/redis:v7.2.1-0

silent-river                    ghcr.io/acorn-io/redis:v7.2.1-0*         d370f07e9b73   39m ago                                                                        OK

2. Deploy a consume app using example app in - https://github.com/acorn-io/aws/tree/main/elasticache/redis/examples/echo-app

Modified the Acronfile to consume the redis app deployed in step1:

services: redis: {
external: "silent-river"
}
containers: app: {
build: context: "./"
ports: publish: ["5000/http"]
env: {
		REDIS_HOST: "@{service.redis.address}"
		REDIS_PORT: "@{service.redis.port.6379}"
		REDIS_PASSWORD: "@{service.redis.secrets.admin.token}"
	}
}

4. Once the app is deployed , try to access the endpoint url.

Endpoint url is not rendered.

Note - I am able to consume redis service successfully using the example app provided in https://github.com/acorn-io/redis/tree/main/examples

Hi @sangee2004,
thanks for reporting this issue.
Could you run a shell in your app container and confirm the env vars are correctly set ?

@lucj I see the REDIS env variables set from the consuming app

%acorn apps

Hum, I think it's more related to flask (I can be wrong though) as when I run a shell in the container, I can connect to the redis service (after installing the redis-cli client):

/src # redis-cli --pass i85b0373210hi7h5 -h "db.myredis-a85ed76a-874.svc.cluster.local"
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
