Step 6 - Run docker container from the image *docker run -p 8080:80 myapp* This tells Docker to run the myapp container and map port 8080 on your local machine to port 80 inside the container Step 7 - Access the app Open a web browser and navigate to http://localhost:8080 to see the "Hello, world!" message displayed in your web browser. If you are using AWS EC2 Linux, you will need to make sure that the security group for your AWS Linux instance allows inbound traffic on port 8080 (or whichever port you chose to map to port 80 inside the container). Here's how to modify the security group: Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/. In the navigation pane, choose "Instances". Select your AWS Linux instance in the list. Choose the "Security" tab in the bottom pane. Select the security group associated with your instance and choose the "Edit inbound rules" button. Add a new rule with the following settings: Type: "Custom TCP Rule" Protocol: "TCP" Port Range: "8080" (or whichever port you chose to map to port 80 inside the container) Source: "0.0.0.0/0" (or restrict the source IP address range to your specific needs) After modifying the security group, you should be able to access the web page served by your Docker container by navigating to http://＜Public_IP_of_your_instance＞:8080 in a web browser.
