How to Install Podman on CentOS 8
Containerization has become an integral part of modern software development, enabling developers to create, deploy, and run applications in isolated environments. Podman, a container management tool, provides a lightweight and daemonless alternative to Docker. If you're using CentOS 8 and looking to harness the power of Podman, this guide will walk you through the installation process.
Before you begin, make sure you have a CentOS 8 system with administrative privileges.
Step 1: Update System Packages
Ensure that your system's package repositories are up to date by running the following commands:
sudo dnf update -y
Step 2: Install Podman
Podman is available in the default CentOS 8 repositories. Install it using the following command:
sudo dnf install -y podman
Step 3: Verify Installation
After the installation is complete, verify that Podman is installed successfully by checking the version:
Step 4: Basic Podman Commands
List Running Containers:
To view the list of currently running containers, use the following command:
Search for Images:
Explore available container images on the default registry by using:
podman search <image_name>
Step 5: Pulling and Running a Container
Let's pull and run a simple container to test Podman. Consider the example of an Nginx web server:
podman run -d -p 8080:80 --name my_nginx nginx
This command pulls the Nginx image and runs it as a detached container, exposing port 8080 on the host.
Step 6: Accessing the Containerized Application
Open your web browser and navigate to
http://localhost:8080. You should see the default Nginx page, indicating a successful deployment.
Explore additional Podman capabilities by experimenting with commands like:
Building a custom image:
podman build -t custom_image .
Running a container with a specific user:
podman run --userns=keep-id -it --rm fedora
Congratulations! You've successfully installed Podman on CentOS 8 and run a containerized application. Podman offers a versatile and lightweight container management solution, making it a valuable tool for developers and system administrators alike.
