The Complete Practical Docker Guide - Running Container with Pseudo TTY

The video tutorial explains the use of the -i and -t options in the Docker run command. It demonstrates how these options work individually and in combination to provide interactive terminal access to containers. The tutorial also covers the differences between using these options with Alpine and Ubuntu images, highlighting the behavior of the default shell processes in each case.

What is the primary purpose of the -T option in the Docker run command?

• To specify the container's network

• To run the container in detached mode

• To connect to the standard input

• To allocate a pseudo-terminal

When using only the -i option with an Alpine container, what is a notable limitation?

• Lack of command prompt formatting

• Inability to create new folders

• Lack of network connectivity

• Inability to list files

What happens when you use only the -t option with a Docker container?

• The container fails to start

• You get a command prompt but cannot input commands

• You can input commands but have no command prompt

• The container runs in detached mode

Why is it necessary to combine the -i and -t options when running a Docker container?

• To specify the container's network settings

• To enable both input and formatted output

• To run the container in detached mode

• To allocate more memory to the container

What is the default shell used in an Ubuntu container when using the -it options?

• Csh

• Bash

• Fish

• Zsh

How does the shell in an Ubuntu container differ from the one in an Alpine container?

• Ubuntu uses Bash, while Alpine uses Ash

• Ubuntu uses Csh, while Alpine uses Zsh

• Ubuntu uses Fish, while Alpine uses Csh

• Ubuntu uses Zsh, while Alpine uses Bash

What command can be used to exit a shell in a Docker container?

• terminate

• quit
