I used 2 pods and service on my Kubernetes cluster. They are Redis and my nodeJs application. Also I used scaffold for dev environment.
I want to connect Redis from my nodeJs application. I set environment variable on my nodeJs_app.yaml file for connection to Redis.
My nodeJs_app.yaml file look like:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nodeJsApp
spec:
replicas: 1
selector:
matchLabels:
app: no
template:
metadata:
labels:
app: nodeJsApp
spec:
containers:
- name: nodeJsApp
image: nodeJsApp
env:
- name: REDISCONNECTIONDEV
value: "redis://redis-srv:6379/"
---
apiVersion: v1
kind: Service
metadata:
name: nodeJsApp
spec:
type: NodePort
selector:
app: nodeJsApp
ports:
- name: nodeJsApp
protocol: TCP
port: 3000
nodePort: 30001
Also my Redis.yaml file like that:
apiVersion: apps/v1
kind: Deployment
metadata:
name: redis-depl
spec:
replicas: 1
selector:
matchLabels:
app: redis
template:
metadata:
labels:
app: redis
spec:
containers:
- name: redis
image: redis
---
apiVersion: v1
kind: Service
metadata:
name: redis-srv
spec:
selector:
app: redis
ports:
- name: redis
protocol: TCP
port: 6379
targetPort: 6379
I checked with kubectl get pods and kubectl get services and each services and ports running correctly.
On my NodeJs_app/index.js file I tried to connect Redis service with:
let REDIS_URL = process.env.REDISCONNECTIONDEV || production_redis_url;
let redisQueue = new Queue('my queue', REDIS_URL);
redisQueue('global:completed', (jobId, result) => {
// console.log(`Job completed with result ${result}`);
});
But this situation return an error like that:
/app/node_modules/redis-parser/lib/parser.js:179
return new ReplyError(string)
^
ReplyError: ERR value is not an integer or out of range
at parseError (/app/node_modules/redis-parser/lib/parser.js:179:12)
at parseType (/app/node_modules/redis-parser/lib/parser.js:302:14) {
command: { name: 'select', args: [ 'NaN' ] }
}
Also I'm new to Redis. Why this problem is occuring? How can I solve this?
