As stated in the title I am experiencing error

Back-off restarting failed container while creating a service

I've seen questions on Stack Overflow but I am still not sure how to resolve it.

This is my deployment yaml file:

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: book-api

spec:

  replicas: 1

  revisionHistoryLimit: 10

  template:

    metadata:

      name: book-api

      labels:

        app: book-api

    spec:

      containers:

      - name: book-api

        image: newmaster/kubecourse-books:v1

        ports:

        - name: http

          containerPort: 3000

while the service deployment file is:

kind: Service

apiVersion: v1

metadata:

  name: exampleservice

spec:

  selector:

    app: myapp

  ports:

    - protocol: "TCP"

      # Port accessible inside cluster

      port: 8081

      # Port to forward to inside the pod

      targetPort: 8080

      # Port accessible outside cluster

      nodePort: 30000

  type: LoadBalancer

This is my Dockerfile:

FROM node:alpine



# Create app directory

WORKDIR /src



# Install app dependencies

COPY package.json /src/

COPY package-lock.json /src/



RUN npm install



# Bundle app source

ADD . /src



RUN npm run build



EXPOSE 3000



CMD [ "npm", "run serve" ]

I have no idea how to resolve this issue, I am newbie in the Kubernetes and DevOps world.
Repo is over here: https://github.com/codemasternode/BookService.Kubecourse.git

I tried to run your deployment locally and this is what the log shown:

kubectl log book-api-8d98bf6d5-zbv4q

where <command> is one of:

Specify configs in the ini-formatted file:

or on the command line via: npm <command> --key value

Config info can be viewed via: npm help config



npm@6.5.0-next.0 /usr/local/lib/node_modules/npm

It seems no command is running by default with the newmaster/kubecourse-books:v1

I guess if you want to run the default npm command, you could run the following deploy config (note the command value):

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: book-api

spec:

  replicas: 1

  revisionHistoryLimit: 10

  template:

    metadata:

      name: book-api

      labels:

        app: book-api

    spec:

      containers:

      - name: book-api

        image: newmaster/kubecourse-books:v1

        command: ["npm", "start"]

        ports:

        - name: http

          containerPort: 3000
