Docker is one of the widely used solutions to build and run programs, applications, and software under different environments or OS systems. This can be done through Docker images that run the containers of different platforms such as Linux containers by executing “ubuntu” or “alpine” images, Windows containers, and MacOS. This feature of Docker helps us to execute the application of different platforms like the Linux application on Windows OS.
In this article, we will demonstrate how to run bash in Ubuntu Docker container with a single command.
How to Run Bash in Ubuntu Docker Container With a Single Command?
Bash is a shell and command line language that is mostly used as the default login shell in the Linux distribution.
To run the bash shell in an Ubuntu container using a single command, simply use the given command:
In the above command:
- “docker run” is an official Docker command used to create and start the container from the provided image. To run Ubuntu or Linux containers, we have utilized the “ubuntu:latest” Docker image.
- “-it” option is utilized to execute the container interactively and allocate the TTY pseudo-terminal to the container.
- “/bin/bash” are the executables of the container to run bash in the Ubuntu Docker container:
Alternatively, In order to automatically remove the container after using the Ubuntu bash shell, use the “–rm” flag:
Now, the user can use the container to do any Linux-based activity or run any command. For demonstration, follow the listed instructions.
Step 1: List all Ubuntu Container Directories
List down all Ubuntu container directories or files using the “ls” command:
The output shows all the container directories.
Step 2: Open “home” Directory
Next, navigate to any of the listed directories. For instance, we have opened the “home” directory using the “cd” command:
To view the currently opened directory, utilize the “pwd” command:
Step 3: Create New File Using “Touch” Command
Next, create a new file using the Linux command line utility “touch” command:
For confirmation, list down all the files and directories of the currently open directory:
Here, you can see we have successfully created the new file in a Linux container using Bash shell:
Step 4: Exit the Bash Shell
To exit the container bash shell, utilize the “exit” command:
That’s all about running bash in Ubuntu Docker container with a single command.
Conclusion
To run the bash shell in the Ubuntu Docker container using a single command, simply execute the “docker run -it ubuntu:latest /bin/bash” command. This command will automatically run the container and open the bash shell, where the user can execute any Linux command. This blog has demonstrated how to run bash in Ubuntu containers.
