Create a file named package.json that contains the following.

{
  "name": "my-nodejs-image",
  "version": "1.0.0",
  "description": "my NodeJS image"
}

Create a file named Dockerfile that contains the following.

FROM node:18-alpine
WORKDIR /src/
COPY package.json /src/
RUN npm install --omit=dev
EXPOSE 12345

On your Docker server, use the docker build command to create the Node.js image.

sudo docker build --file Dockerfile --tag nodejs:18-alpine .

The docker images command should return something like this.

~]$ sudo docker images
REPOSITORY        TAG          IMAGE ID       CREATED         SIZE
nodejs            18-alpine    824127ec51d1   1 minute ago    189MB

The docker run command can be used to create and start a Docker container from the image.

sudo docker run \
--name nodejs \
--publish 0.0.0.0:12345:12345 \
--detach \
nodejs:18-alpine

The docker container ls command should show the container is up and running.

~]$ sudo docker container ls
CONTAINER ID   IMAGE                      COMMAND                  CREATED        STATUS         PORTS                         NAMES
c19d5eab9a75   nodejs:18-alpine           "docker-entrypoint.s…"   1 minute ago   Up 1 minute    0.0.0.0:12345->12345/tcp    nodejs

The docker logs command should return nothing since this is just a totally empty Node.js container.

sudo docker logs nodejs
