Simon Coter (Director of Product Management) has pleased to tannounce the latest stable release of Oracle Linux 8 on 18th July 2019.
Oracle Linux 8 ships with Red Hat Compatible Kernel (RHCK) kernel-4.18 and distributed through a combination of BaseOS and Applications Streams.
Oracle Linux (OL, formerly known as Oracle Enterprise Linux) is a Linux distribution packaged and freely distributed by Oracle. It is compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle’s.
Oracle Linux 8 supports the Intel x86_64 & AMD 64-bit architectures. The 64-bit Arm (aarch64) platform can be installed as a developer preview release.
Application Streams & Repository Information:
The core operating system and associated packages for Oracle Linux 8 server are distributed through Applications Streams. Application Streams contain all of the necessary system components and a range of applications that were previously distributed in Software Collections, as well as other products and programs.
AppStreams packages can be delivered and updated more frequently than the core operating system packages.
Oracle Linux 8 repositories are divided into two repositories: BaseOS and AppStream
The BaseOS repository includes the core set of packages that are required for Oracle Linux to function.
The AppStream repository includes packages that provide additional support for a variety of workloads, such as user-space applications, runtime languages, and databases.
The CodeReady Linux Builder repository provides the build packages that are required for developers.
The content in the AppStream repository is available in two formats: RPM and modules.
Modules: Are a set of RPM packages that are grouped and installed together. Modules can contain several streams that consist of multiple versions of applications that can be installed.
Module streams: Contain a different version of packages and their dependencies. Modules can have multiple streams and each stream receives updates independently.
Oracle Linux 8 supports a new version of the Yum tool that is based on the DNF technology. DNF, or Dandified yum, is a software package manager that installs, updates, and removes packages on RPM-based Linux distributions.
YUM version has been upgraded from YUM v3 to YUM v4 & RPM version has upgraded to rpm 4.14.
Cockpit packages are now included in the Oracle Linux default repositories, it allows admin to manage multiple remote system easily through web browser.
Installation, Boot and Image Creation:
A new kernel boot parameter, inst.addrepo=name,url, has been added to the installer. You can use this parameter to specify an additional repository during an installation.
By default, the Oracle Linux 8 installer uses the LUKS2 format. This change introduces several improvements such as extending the capabilities of the on-disk format and providing flexible ways to store metadata.
Linux Container Tools:
These tools are compatible with the Open Container Initiative (OCI) and can be used to manage the same Linux containers that are produced and managed by Docker.
Pod Manager (podman): podman is a daemonless container engine that you can use to develop, run, and manage compatible container images on Linux systems.
Buildah (buildah): buildah command is used to create container images from a working container, a Dockerfile, or from scratch, inspect a container or image, mount and unmount a container, create a new container layer, and delete a container or image.
Skopeo (skopeo): Skopeo is a client tool that you use to work with remote images registries to retrieve information, images, and signing content. You can use the skopeo command to copy container images to and from remote container registries.
