In this tutorial, we will learn about how to install Podman in RHEL using 7 easy steps. As we know, Pods are set of containers that runs together and share same set of resources. Podman manages these pods via command line interface. (CLI). Podman is supported on various Linux distribution like CentOS, RHEL, Fedora etc. Podman installation method on different Linux distribution is different. We will focus on installing Podman on RHEL EC2 instance in AWS.
What is Podman?
Podman, also known as POD manager is a daemonless and open source tool which is used to build images. Podman is a product developed by Red Hat with an intention to develop, manage and build containers in Linux systems.

How to Install Podman in Amazon RHEL[7 Easy Steps]
Prerequisites
- An existing EC2 instance. Check out How to Create EC2 instance for creating a new instance.
- Any SSH client to connect to EC2 instance.
Step-1: Start EC2 instance
In this step, go to AWS management console and search for EC2 service. Select your EC2 instance and click on start instance if your instance is not in running state.
Step-2: Connect to EC2 instance
In this step, connect to the EC2 instance using any SSH client. I am Using Putty to connect to my EC2 instance using key based method. Provide hostname as shown below. Next, then click on SSH -> Auth and select the path of your key file. Once all done, click on Open.
Step-3: Become root
In this step, before starting to install Podman, switch to root user using below command.
[ec2-user@ip-10-162-180-10 ~]$ sudo su [root@ip-10-162-180-10 ec2-user]#
Step-4: Check OS version
In this step, check the OS version of machine using below command.
[root@ip-10-162-180-10 ec2-user]# cat /etc/os-release NAME="Red Hat Enterprise Linux" VERSION="9.0 (Plow)" ID="rhel" ID_LIKE="fedora" VERSION_ID="9.0" PLATFORM_ID="platform:el9" PRETTY_NAME="Red Hat Enterprise Linux 9.0 (Plow)" ANSI_COLOR="0;31" LOGO="fedora-logo-icon" CPE_NAME="cpe:/o:redhat:enterprise_linux:9::baseos" HOME_URL="https://www.redhat.com/" DOCUMENTATION_URL="https://access.redhat.com/documentation/red_hat_enterprise_li nux/9/" BUG_REPORT_URL="https://bugzilla.redhat.com/" REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 9" REDHAT_BUGZILLA_PRODUCT_VERSION=9.0 REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux" REDHAT_SUPPORT_PRODUCT_VERSION="9.0"
NOTE:
Step-5: Update Repo
In this step, update the yum repo using below command. This step will keep the repo upto date with the latest dependencies and packages.
[root@ip-10-162-180-10 ec2-user]# yum -y update Last metadata expiration check: 0:05:11 ago on Mon 03 Apr 2023 10:47:56 AM UTC. Dependencies resolved. Nothing to do. Complete!
Step-6: Install Podman
In this step, install the latest verison of podman using below command.
[root@ip-10-162-180-10 ec2-user]# yum install -y podman Updating Subscription Management repositories. Unable to read consumer identity This system is not registered with an entitlement server.

Step-7: Verify Podman
In this step, once podman installation completes, verify the installation.
[root@ip-10-162-180-10 ec2-user]# podman --version podman version 4.2.0
Conclusion
In this tutorial, we learnt about how to install Podman on RHEL Now that Podman is installed successfully, start building the images and running the container to explore the features and working of Podman.
