Create Replicaset in Kubernetes Cluster Kodekloud

 

Question: The Nautilus DevOps team is going to deploy some applications on kubernetes cluster as they are planning to migrate some of their existing applications there. Recently one of the team members has been assigned a task to write a template as per details mentioned below:

    Create a ReplicaSet using nginx image with latest tag only and remember to mention tag i.e nginx:latest and name it as nginx-replicaset.

    Labels app should be nginx_app, labels type should be front-end. The container should be named as nginx-container; also make sure replicas counts are 4.

Note: The kubectl utility on jump_host has been configured to work with the kubernetes cluster.


Solution: 

Create a file replicaset.yaml

vi replicaset.yaml

Then according to question change the name, type, image name, app name etc.

Then apply

kubectl apply -f replicaset.yaml

apiVersion: apps/v1
kind: ReplicaSet
metadata:
name: nginx-replicaset
labels:
app: nginx_app
type: front-end
spec:
replicas: 4
selector:
matchLabels:
app: nginx_app
template:
metadata:
labels:
app: nginx_app
type: front-end
spec:
containers:
- name: nginx-container
image: nginx:latest
