Flow-2: Create a new Docker Image, Run as Container and Push to Docker Hub¶

Pre-requisite Steps¶

Create your Docker hub account.
https://hub.docker.com/
Important Note: In the below listed commands wherever you see stacksimplify you can replace with your docker hub account id.

Step-1: Run the base Nginx container¶

Access the URL http://localhost

docker run --name mynginxdefault -p 80:80 -d nginx
docker ps
docker stop mynginxdefault

Step-2: Create Dockerfile and copy our customized index.html¶

Dockerfile

FROM nginx
COPY index.html /usr/share/nginx/html

*index.html

<!DOCTYPE html>
<html>
   <body style="background-color:lightgoldenrodyellow;">
      <h1>Welcome to Stack Simplify</h1>
      <p>Docker for Beginners Demo</p>
      <p>Application Version: V1</p>
   </body>
</html>

Step-3: Build Docker Image & run it¶

docker build -t stacksimplify/mynginx_image1:v1 .
docker run --name mynginx1 -p 80:80 -d stacksimplify/mynginx_image1:v1

Replace your docker hub account Id
docker build -t <your-docker-hub-id>/mynginx_image1:v1 .
docker run --name mynginx1 -p 80:80 -d <your-docker-hub-id>/mynginx_image1:v1

Step-4: Tag & push the Docker image to docker hub¶

docker images
docker tag stacksimplify/mynginx_image1:v1 stacksimplify/mynginx_image1:v1-release
docker push stacksimplify/mynginx_image1:v1-release

Replace your docker hub account Id
docker tag <your-docker-hub-id>/mynginx_image1:v1 <your-docker-hub-id>/mynginx_image1:v1-release
docker push <your-docker-hub-id>/mynginx_image1:v1-release

Step-5: Verify the same on docker hub¶

Login to docker hub and verify the image we have pushed
