I am new to kubernetes and trying to create a deployment. So first I created a replicaset named rs.yml shown below.
apiVersion: apps/v1
kind: ReplicaSet
metadata:
name: web
labels:
env: dev
role: web
spec:
replicas: 4
selector:
matchLabels:
role: web
template:
metadata:
labels:
role: web
spec:
containers:
- name: nginx
image: nginxand applied it using
kubectl apply -f rs.yml
now Instead rewriting all this in deployment. I just want to refer this 'rs.yml' file or service inside my deployment.yml file.
You can create single YAMl file and add both thing deployment service inside it.
apiVersion: apps/v1
kind: ReplicaSet
metadata:
name: web
labels:
env: dev
role: web
spec:
replicas: 4
selector:
matchLabels:
role: web
template:
metadata:
labels:
role: web
spec:
containers:
- name: nginx
image: nginx
---
apiVersion: v1
kind: Service
metadata:
name: my-service
spec:
selector:
app: MyApp
ports:
- protocol: TCP
port: 80
targetPort: 9376you can divide the things using the --- make the single YAML file.
also, another suggestion don't use the Replicasets by default Deployment create the Replicaset in the background.
You can use the kind: deployment can check kubectl get rc still replica set will be there. Deployment creates it in the background and manage it.
