Exam 200-901 topic 1 question 282 discussion

To download and run an Apache web server container in Docker with a port binding of 8080 in the container to port 80 on the host, you can use the following two commands: 1. docker pull httpd:latest - This command will download the latest version of the Apache web server Docker image from the Docker Hub. 2. docker run -p 80:8080 -d httpd - This command will start a new container based on the httpd image, with a port binding of 8080 in the container to port 80 on the host. The -d flag runs the container in detached mode, meaning it will run in the background and not block the terminal.

"a port binding 8080 in the container to 80 on the host" Docker documentation specifies the order "-p host:container" C and D are correct

B and D period

To download and execute an Apache web server container in Docker with a port binding where port 8080 in the container is mapped to port 80 on the host, you need to use the docker pull command to pull the Apache image and the docker run command to start the container with the appropriate port mapping. Here are the two commands to achieve this: Download the Apache image: A. docker pull httpd This command pulls the Apache HTTP Server image (httpd) from the Docker Hub. Execute the Apache container with port mapping: B. docker run -p 8080:80 httpd This command runs the Apache container with port 8080 on the host mapped to port 80 in the container. The -p option specifies the port mapping. So, options B and D are the correct commands for downloading and executing an Apache web server container with the specified port binding.

"-p=[] : Publish a container's port or a range of ports to the host format: ip:hostPort:containerPort" aka 80 (host port) : 8080 (internal port)

As per outrageous7

<port you are exposing>:<internal port> that's the way !!
