Deploy Nginx Container on Application Server.md

Problem Statement

On Application Server 3, you need to create a Docker container named nginx_3 using the nginx image with the alpine tag. Ensure that the container is started and running.

Solution

To create and run the nginx_3 container with the specified image and tag, follow these steps:

1. Create and Start the Container

   Use the docker run command to create a new container from the nginx:alpine image. The -itd flags are used to run the container in interactive mode with a terminal attached, and in detached mode (in the background). The --name option specifies the name of the container.

   docker run -itd --name=nginx_3 nginx:alpine

   • docker run: Command to create and start a new container.
   • -itd: Combined flags where -i stands for interactive mode, -t allocates a pseudo-TTY, and -d runs the container in detached mode.
   • --name=nginx_3: Names the container nginx_3.
   • nginx:alpine: Specifies the image to use, which is nginx with the alpine tag.

2. Verify the Container is Running

   After running the command, check that the container is up and running by listing all running containers. This ensures that the container named nginx_3 is active and operational.

   docker ps

   This command will show a list of all currently running containers. Look for nginx_3 in the output to confirm that it is running.
