What is Docker?

Docker is an open-source platform for creating and managing containers. It is a powerful tool for developers to quickly and easily create, deploy, and manage applications in a secure and isolated environment. Docker containers are lightweight, portable, and self-contained, making them ideal for running applications in production.

What is the Docker Exec Command?

The <a class="wiki-link" href="/blog/en/kubernetes/docker/convert-docker-compose-to-kubernetes">docker</a> exec command is used to execute a command inside a running container. It allows developers to run commands inside a container without having to start a new container. This is useful for debugging, testing, and troubleshooting applications.

How to Execute a Bash Shell Inside a Container

To execute a Bash shell inside a container, use the <a class="wiki-link" href="/blog/en/kubernetes/docker/what-is-docker-compose">docker</a> exec command with the -it flag. The -it flag tells Docker to open an interactive terminal session inside the container.

For example, to open a Bash shell inside a container named my-container, run the following command:

docker exec -it my-container bash

This will open a Bash shell inside the container. You can then run commands inside the container, such as listing the contents of the current directory:

ls
