I am new to kubernetes. I am running my kubernetes cluster inside my Docker Desktop VM. Below are the versions
Docker Desktop Community : 2.3.0.4 (Stable)
Engine: 19.03.12
kubernetes: 1.16.5
i created a simple react app. below is the Docker file.
FROM node:13.12.0-alpine
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH
COPY package*.json ./
RUN npm install
# add app files
COPY . ./
# start app
CMD ["npm", "start"]
I built a docker image and ran it. it works fine. I added the image in the below deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: test-deployment
labels:
app: test-react-app
namespace: dev
spec:
replicas: 1
selector:
matchLabels:
app: test-react-app

The pod never starts. Below is the events from describe.

It worked!!!
I build the react app into a production app and then copied the docker file. I followed the technique given in this link https://dev.to/rieckpil/deploy-a-react-application-to-kubernetes-in-5-easy-steps-516j.
