Find and get secure container images
Find container images that are tested, secured, and stored by Red Hat. Use the resources on this tab to search for images using the Red Hat Container Catalog or command-line tools. After that, try pulling those images to your local system so they are ready to run.
Use the Red Hat Container Catalog to find images
Use the Red Hat Container Catalog (RHCC) to find container images that have been tested, secured, and verified by Red Hat.
Use the RHCC directly, or access it from the Get Started guide, FAQ, or Explore page. Use these resources to find:
- Base Images (standard RHEL and minimal Atomic images) in documentation or in the RHCC
- Builder Images (prebuilt for different runtime environments) in documentation or in the RHCC
- Applications Images (images that run on their own) in the RHCC
- Images based on category, such as Container Platform/Management, Operating System, Mobile Application Development Platform, Programming Languages and Runtimes, Logging and Monitoring, or Virtualization Platform
Use commands to search for images (public and private)
Use commands such as "docker search" to find images from the Red Hat Registry or the Docker Hub. Use other commands such as "curl" to find images in a private registry. List images from:
Pull containers to your local system
Acquire a container image from a registry by pulling it to your local system.
Run individual container images
Many containers run with a simple docker command, but others are specially configured to run with other tools. Use these resources to run containers with different tools and to learn how to run special types of containers.
Run containers with docker and oc commands
Run individual or standard images with the docker command. Use the OpenShift oc command to create and run applications.
- Inspect and run docker-formatted containers
- Create and run container applications, including Source-to-image images, Database images, Docker images, and Other images
Run special container types with the atomic command
Many Red Hat containers can run differently with the atomic command. Super privileged containers can open privileges to the host system, to provide services such as monitoring or troubleshooting. System containers can start up before the docker service (and can even start on systems that are not running the docker service).
Develop containers
With your container development platform in place, start putting together the necessary pieces to begin developing containers.
Prepare to develop containers
- Plan your container development process in OpenShift
- Step through the process and components for building container images
- Learn guidelines specific to Docker and OpenShift for building images
- Determine if you want to create an application using the command line (from template, source code, or an image) or the OpenShift Web console
- Use application components to define how containers are configured and moved between environments. Follow these container developer scenarios and examples.
- Three reasons for containerizing applications on RHEL and OpenShift
- Create an environment to design and develop microservices in OpenShift with Fuse Integration Services
Look for Red Hat OpenShift Application Runtimes (RHOAR) as they become available. Announced, supported runtimes include: Spring Boot, Eclipse Vert.x , JBoss® EAP, Eclipse Microprofile , and WildFly Swarm
Develop containers for different runtimes
Develop your own container images using docker build or by injecting code into special builder images using Source-to-Image (S2I) tools. These procedures describe different builder images to use with S2i tools to build your own images for different runtime environments:Develop containers for other types of applications

Topics
Browse container topics from security, performance, and orchestration to storage and more.
Red Hat Container Security
Securing containers inside and out
Red Hat provides consistent security across all aspects of container build, run, and deployment environments. The foundation of Red Hat's container security model is Red Hat Enterprise Linux (RHEL).
Red Hat Container Images
Using Red Hat container images
Red Hat builds container images from RHEL software. Hundreds of secure images are available from Red Hat to run directly or use as the base for images you build.
Red Hat Container Performance
Performance tuning containers
Red Hat's container performance initiatives focus on how individual containers perform. They also show you how to optimize the Red Hat host systems and infrastructure to support those containers.
Red Hat Container Orchestration
Understanding Kubernetes
OpenShift uses Kubernetes to provide the underlying orchestration layer for Red Hat container technologies.
Red Hat Container Storage
Connecting containers to storage
Mounting volumes inside containers allows data storage to persist as containers come and go. Red Hat supports shared volumes using NFS, Ceph, GlusterFS, GCE, AWS and other storage technologies.
Red Hat Container Products
Red Hat offers platforms to deploy, build, store, and secure enterprise Linux containers.
OpenShift
Red Hat OpenShift provides a complete platform to build, develop, and deploy containers on private or public infrastructures. OpenShift Container Platform lets you create your own on-premise OpenShift infrastructure. OpenShift Dedicated and OpenShift Online offer hosted OpenShift services.

Container Catalog and Registries
Containers usher in a new way to create and manage applications. The Red Hat Container Catalog (RHCC) lists container images that are tested, secured, and regularly updated. By pulling images from the Red Hat Registry, you can use them as the foundation of your own containers. When you create these images, you can store them in your own OpenShift Container Registry.
Red Hat Container Catalog
The RHCC lists all official container images from Red Hat. From the RHCC, search for the container images you need, and then read about the contents and security level of each image. The RHCC also describes how to get and use the image. To learn more:
Red Hat Registry
Most container images listed in the RHCC are stored in the Red Hat Registry. RHEL systems with an active container service (such as the docker daemon) are pre-configured to search and pull from the Red Hat Registry. To obtain images from other registries, you may need to reconfigure your container service.
OpenShift Container Registry
The OpenShift Container Registry provides an internal, integrated Docker registry that you can deploy in your OpenShift Container Platform environment to locally manage container images.

Atomic Host and RHEL Server
RHEL serves as the operating system platform for all container-related Red Hat technologies. RHEL Server and RHEL Atomic Host are variants of RHEL that can be specifically configured to work with containers. RHEL Server provides more flexibility for using containers, while RHEL Atomic is designed for efficient container deployment.
RHEL Atomic Host
Deploy and scale enterprise-quality containerized applications on the RHEL Atomic Host operating system. Atomic Host systems are built and tuned to run containerized tools, including Kubernetes and Docker-formatted containers. You can install RHEL Atomic Host on bare metal or run them with a set of images specially tuned for cloud environments.
