“Describe the function of the following Docker commands and briefly explain the purpose of each of the parameters.

docker run –d –p 8080:5000 –v $(pwd)/data:/data –name container1 lab4

Docker is a software containerization platform, that runs processes in isolated containers. The docker run command is used to define the containers resources at runtime. When the command is run, the container process is isolated. It is separate from the host itself. The –d command is an option run by Docker to communicate whether the container should be run in “detached” mode or in the “default mode”. The –d command signifies that the container should be run in detached mode, meaning the container will be run in the background. The next option used is –p. This is used to publish all exposed ports to the host interfaces. Docker, in turn, ‘binds’ each of the exposed ports to a host port, addresses of the published ports are 8080:5000. …show more content…
The –v command can be used multipule times to mount datat volumes. Here it is mounted once. The pwd command prints the working directory i.e. data:/data. The –name command assigns the name container1 lab4 as the container name.

docker exec –it A637jd9dja /bin/bash

The docker command docker exec runs a new command in an already running container. The command only runs while the containers PID (primary process) is running. If the container is paused the command will yield an error and fail.
-it runs the container, and has bash available in the same terminal. This will create a new bash session in the running container with an ID/name of A637jd9dja. /bin/bash is used as some containers don’t have bash in the path.

docker create –v /data --name datastore1 hello-world
