I need help to understand how can I update my svc configuration using a json file : my svc is up and runing but it is not the type i want, it is a cluster ip and I'd like to change it to a ingress kind and type load balancer: curently here is the service :
kubectl -n nifitest get svc -o wide
simplenifi-all-node ClusterIP 192.164.115.193 <none> 8080/TCP,6007/TCP,10000/TCP 44h app=nifi,nifi_cr=simplenifinow I want to deploy a service that point to the ingress
so is tere a kubectl command like apply to use a json file and will it update the svc using a json file ?
Thank you for your help
You need to create new service with loadbalancer type. You cannot update the previous one (from type: ClusterIP to type: LoadBalancer) cause it is immutable.
By the way, I have given the format of loadbalancer service in both yaml and json as an example template, you can use them according to your need.
In Json format:
{
"apiVersion": "v1",
"kind": "Service",
"metadata": {
"name": "my-service"
},
"spec": {
"selector": {
"app": "MyApp"
},
"ports": [
{
"protocol": "TCP",
"port": 80,
"targetPort": 9376
}
],
"clusterIP": "192.164.115.193",
"type": "LoadBalancer"
},
"status": {
"loadBalancer": {
"ingress": [
{
"ip": "192.0.2.127"
}
]
}
}
}
In Yaml format:
apiVersion: v1
kind: Service
metadata:
name: my-service
spec:
selector:
app: MyApp
ports:
- protocol: TCP
port: 80
targetPort: 9376
clusterIP: 192.164.115.193
type: LoadBalancer
status:
loadBalancer:
ingress:
- ip: 192.0.2.127
