Red Hat OpenShift Development I: Introduction to Containers with Podman
As organizations continue to adopt cloud-native technologies, containers have become a fundamental part of modern software development and deployment. Red Hat OpenShift Development I: Introduction to Containers with Podman (DO188) is an entry-level course designed to help developers, system administrators, and IT professionals understand how to build, run, and manage containerized applications using Podman before deploying them to Red Hat OpenShift. The course emphasizes hands-on practical skills that are directly applicable to modern enterprise environments. <Cite refs={[“turn0search0″,”turn0search1”]}/>
Understanding Containers
Containers package an application together with its dependencies, libraries, and configuration files into a portable unit. Unlike traditional virtual machines, containers share the host operating system kernel, making them lightweight and fast to start.
This approach provides several advantages:
- Consistent application behavior across development, testing, and production environments.
- Faster application deployment.
- Efficient use of computing resources.
- Easier collaboration between development and operations teams.
- Improved scalability for cloud-native applications.
These benefits make containers an essential technology for DevOps and modern application development.
Why Podman?
Podman is Red Hat’s container management tool and is designed as a secure, daemonless alternative for working with OCI-compatible containers. One of its major advantages is its support for rootless containers, allowing users to create and manage containers without requiring administrator privileges.
During the DO188 course, learners gain practical experience with Podman commands to:
- Download container images from registries.
- Create and run containers.
- Inspect container configurations.
- Manage container lifecycles.
- Build custom container images.
- Work with pods containing multiple containers. <Cite refs={[“turn0search0″,”turn0search23”]}/>
What You Will Learn
The course follows a practical, hands-on approach and covers the core concepts required to work with containers effectively.
1. Introduction to Containers
Students begin by understanding container architecture, container images, registries, and how containers differ from virtual machines.
2. Running Containers with Podman
Learners use the Podman command-line interface to create, start, stop, inspect, and remove containers.
3. Managing Container Images
The course demonstrates how to search for images, download them from registries, tag images, and manage local image repositories.
4. Building Custom Container Images
Students learn how to write Containerfiles and create custom images that package their own applications and dependencies.
5. Persistent Storage
Since containers are designed to be temporary, the course explains how volumes are used to preserve application data, including database information.
6. Container Networking
Participants learn how containers communicate with each other and how applications running inside containers can be accessed through network ports.
7. Multi-Container Applications
The course introduces pods, allowing related containers to run together and share networking resources.
8. Introduction to OpenShift
Finally, students gain an introduction to deploying containerized applications on Red Hat OpenShift, helping bridge the gap between local container development and enterprise Kubernetes platforms. <Cite refs={[“turn0search0″,”turn0search5”]}/>
Who Should Attend?
This course is ideal for:
- Software developers beginning their cloud-native journey.
- Linux system administrators.
- DevOps engineers.
- Application support engineers.
- IT professionals planning to work with Red Hat OpenShift or Kubernetes.
Basic Linux command-line knowledge is recommended, but no prior container experience is required.
Career Benefits
Completing this course helps learners develop skills that are increasingly in demand across the IT industry. Participants become better prepared for roles such as:
| Role | Skills Gained |
|---|---|
| DevOps Engineer | Containerization and deployment |
| Cloud Engineer | Cloud-native application packaging |
| OpenShift Developer | Building and deploying containers |
| Linux Administrator | Podman and container management |
| Platform Engineer | Foundations for Kubernetes and OpenShift |
The course also provides a strong foundation for progressing to more advanced Red Hat OpenShift and Kubernetes training, as well as the Red Hat Certified Specialist in Containers certification path. <Cite refs={[“turn0search1″,”turn0search0”]}/>
