![]() Let’s demonstrate how to build on the UBI Micro image using Buidlah. To add packages to UBI Micro, you use Buildah on the container host. You might be asking yourself, how do I add packages to UBI if there’s no package manager? Don't worry, it's not hard. This gives it the best characteristics of a distroless image, and traditional container image merged into one. UBI Micro leverages the advantages of a “distroless” image, because it has no package manager (YUM/RPM), but it’s still constructed from RHEL packages. The popularity of tiny images has exploded over the last couple of years, but the world has lacked a tiny container image that fits into the existing software ecosystem. This is a long awaited feature which brings RHEL-based tiny container images to the world. If you need active support, please move to the 2.0 or 3.0 stable streams. If you’re interested in this use case, check out the Container Tools Application Streams in RHEL 8.4.Īs a reminder, and per the Application Streams Life Cycle page, with the launch of our latest Container Tools fast and stable streams, the Container Tools 1.0 stream moves out of support. Many upstream tools like kind, minikube, syft, and grype have had success using the Docker compatible endpoint in Podman. ![]() Many new API endpoints have been implemented which enables a lot of legacy software to function using Podman. In particular Podman 3.0 brings with it a lot of exciting new features that give users access to a Docker-compatible socket. container-tools 3.0 common Stable versions of podman 3.0, buildah 1.19, skopeo 1.2, runc, conmon, etc as well as dependencies such as container-selinux built and tested together, and supported as documented on the Application Stream lifecycle page.Īs you can see in the output, the latest fast and stable streams provide Podman 3.0, Buildah 1.19, and Skopeo 1.2. container-tools 2.0 common Stable versions of podman 1.6, buildah 1.11, skopeo 0.1, runc, conmon, etc as well as dependencies such as container-selinux built and tested together, and supported as documented on the Application Stream lifecycle page. container-tools 1.0 common Stable versions of podman 1.0, buildah 1.5, skopeo 0.1, runc, conmon, CRIU, Udica, etc as well as dependencies such as container-selinux built and tested together, and supported for 24 months. Output: container-tools rhel8 common Most recent (rolling) versions of podman, buildah, skopeo, runc, conmon, runc, conmon, CRIU, Udica, etc as well as dependencies such as container-selinux built and tested together, and updated as frequently as every 12 weeks. You can easily see the versions of Podman, Buildah and Skopeo with a single command: yum module list | grep container-tools In RHEL 8, we provide two main types of application streams for the container tools: one fast, one stable for 24 months. Technology Preview of The crun Container Runtime New fast and stable streams with Podman 3.0 Here’s a quick summary of what’s new in RHEL 8.4: ![]() This is a major update since RHEL 8.3 ( Updates to Container Tools in Red Hat Enterprise Linux 8.3) and if you have been looking to move from Docker on RHEL 7 to Podman on RHEL 8, this is a great time to look at doing an upgrade. In this post we'll look at major new features and additions to Podman, UBI, automatic image updates and much more. The update of Container Tools in RHEL 8.4 brings a lot of great new features. Plans for the crun container runtime in RHEL 8 and future versions of RHEL. A look at Podman 3.0 and the fast and the stable application streams for Red Hat Enterprise Linux (RHEL).ĭiscussion of features like secure short names and automatic image updates.
