Tutorial: How to Install and Use docker exec on Arch Linux

In this tutorial, we will guide you through the process of installing and utilizing the docker exec command on Arch Linux. Docker is a popular platform for developers and system administrators to build, ship, and run applications within containers. The docker exec command allows users to execute commands within a running Docker container.

What is docker exec?

The docker exec command is used to run commands inside a Docker container that is already running. This can be helpful for troubleshooting, debugging, or executing specific tasks within a container without the need to start a new container instance.

Installing Docker on Arch Linux

Before using the docker exec command, you need to have Docker installed on your Arch Linux system. You can install Docker on Arch Linux by following these steps:

1. Update your package repository:

   sudo pacman -Syu
   

2. Install Docker using pacman:

   sudo pacman -S docker
   

3. Start and enable the Docker service:

   sudo systemctl start docker
   sudo systemctl enable docker
   

4. Verify the installation by running:

   docker --version
   

Using docker exec

Once you have Docker installed, you can use the docker exec command to execute commands within a running container. The basic syntax for docker exec is as follows:

docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

For example, to run a simple command within a running container named my_container, you can use:

docker exec -it my_container ls -l

In this command:

• -it flag allows for an interactive session within the container.
• my_container is the name of the running container.
• ls -l is the command to list files in the container.
