have been hard at work lately on a project surrounding container updates, new images, new registries, and distribution. Cloud and Containers SIG : All container images are available for both the x86_64 and arm64/v8 architectures. FYI Full UBI Compatible Container Set for Red Hat Universal Base Images (UBI). AlmaLinux provides fully compatible alternatives What is you may ask? UBI is meant to be OCI-compliant container base operating system images with complementary runtime languages and packages included. UBI Prior to UBI, developers would need to package their containerized app depending on the deployment target. This essentially made those containers not really all that portable. UBI allow you to essentially have a standard, repeatable build, and deployment for your code and application, regardless of deployment target. The UBI compatible images come in four variants: Minimal, Base, Micro, and Init. Here is a quick summary of what they offer: : The container image isn’t going away; it’s been updated. FYI Default : A minimal, compacted image that contains a limited package set and uses the microdnf package manager as a replacement for DNF. A minimal DNF uses libdnf and therefore doesn't require Python. This image is 52% smaller in size (37MB download, 102MB expanded). It is designed for applications that come with their dependencies bundled like GO, NodeJS, Java. Minimal Container image tag for Minimal (Platform): almalinux:minimal Container image tag for Minimal (UBI alternative): almalinux/8-minimal : An image designed to be a base for your containerized applications, middleware and utilities. The Base image includes some helpful OS tools like find, tar, vi, etc., and a full DNF stack. The systemd initialization system and access to free dnf repositories are fully available. Base Container image tag: almalinux/8-base : An even more minimized image. It is distributed without any package manager. The Micro image uses the package manager on the underlying host to install packages, typically using Buildah or Multi-stage builds with Podman. The Micro image is 82% smaller than the Base image and 68% smaller than the Minimal image. Since this image has only very few packages, it is more secure compared to other images. Micro Container image tag: almalinux/8-micro : For running multiple applications with an init system. As a default, systemd is enabled for use. Init Container image tag: almalinux/8-init Container Security/Package Updates, New Registries and Distribution In addition to all of the above, two of our images are available as images: and . Both of those have now been updated with the latest security fixes and package updates. Official Docker Hub Default Minimal : A general purpose (platform) container image that contains default packages and can be used as a drop-in replacement for the CentOS 8 image. Default Container image tag: almalinux:latest : A minimal, compacted image that contains a limited package set and uses the microdnf package manager as a replacement for DNF. A minimal DNF uses libdnf and therefore doesn't require Python. This image is 52% smaller in size (37MB download, 102MB expanded). It is designed for applications that come with their dependencies bundled like GO, NodeJS, Java. Minimal Container image tag for Minimal (Platform): almalinux:minimal Container image tag for Minimal (UBI alternative): almalinux/8-minimal All images are available at AlmaLinux's and . Docker Hub quay.io All AlmaLinux images will be published to AWS' Service in the future. If you're running container-based workloads on AWS on either ECS, EKS, or anywhere else really, AlmaLinux containers are available to you locally on AWS. ECR Container Registry More information coming soon about additional container registries and application specific images like Java JDK, NodeJS, and more. To learn more about AlmaLinux container images, you can check out the containers section of the . There you can find helpful information, details about each container, container tags, and links for the repositories for each image. AlmaLinux Wiki Containers are a lightweight version of the OS with an essential base for you to build upon. AlmaLinux container images are a method of building a containerized application and pushing it to the registry server to share and collaborate with others. Containers also provide some additional advantages for users like high reliability, security, and performance. Community Excellent work from an incredible Community on their contributions, questions, and comments on the issues. Especially two immortal community heroes, and putting in a lot of work. Bala Raman , Elkhan Mammadli You can join the community on the and the for any help and assistance, or to discuss anything mentioned here. AlmaLinux Community Chat AlmaLinux Community Forums You can also join the if you are a DevOps doer, containers are your A-game, you live in k8s, or just want to have a lot of fun building more containers, kubernetes operators, and a whole lot more!
