this sort of mount is brief and endures on host memory.it doesn't permit sharing of mounted data among containers since it's an temporary volume. When the host restarts the information will be no more.
Use Case: It tends to be utilized in the fastest numerical tasks results handling.

Q.1) what is use of "docker update" ?

Ans. 1) The docker update command refreshes the compartment setup progressively. This order is utilized to keep the compartments from go through an excessive number of assets from the docker have.

Q 2) what is the use of "docker wait" ?

Ans.2 ) Docker wait command is used to block or wait until one or more containers stops, and then it shows
the exit code as output, that is why we cannot use the terminal if we are running this command on the terminal.

What is Container?
Containers are instances of Docker images that can be run using the Docker run command.

Docker workflow
User ---> Client ---> Docker host --->registry
