The old Cryostat CR is still available and is used for creating single-namespace Cryostat instances. In order to deploy a new multi-namespace-enabled instance, users can create a new ClusterCryostat Custom Resource ( CR) in OCP after installing or updating the Cryostat Operator. When deploying a multi-namespace Cryostat instance, administrators must be careful and considerate about which projects to select for monitoring, which project to install Cryostat into, and which users to grant access. What this means is that any user who can access the Cryostat instance has access to all target applications in any project visible to that Cryostat instance. Cryostat 2.3 can be deployed such that it discovers target applications in multiple projects, but it does not silo the data. * Kubernetes Namespaces are referred to as Projects in OpenShift Container Platform (OCP).īefore I continue, there is an important caveat to be aware of with this initial support. This is the first half of multi-tenant support in Cryostat. With this release it is now possible to deploy a single Cryostat instance for monitoring and profiling Java application instances across all of your OpenShift projects, whereas previous Cryostat releases required you to deploy one Cryostat instance into each project. See the announcement in full here.Cryostat 2.3 includes another popular community-requested feature: multi-namespace support*. They don't have the best history considering how they closed up OpenSolaris development, but on the Oracle Linux front at least they've been doing some good. Some of the best words I've seen out of Oracle in years. Become a downstream distributor of Oracle Linux. You say that you don’t want to pay all those RHEL developers? Here’s how you can save money: just pull from us. Give your customers more choice.įinally, to IBM, here’s a big idea for you. If you don’t yet support your product on Oracle Linux, we would be happy to show you how easy that is. By killing CentOS as a RHEL alternative and attacking AlmaLinux and Rocky Linux, IBM is eliminating one way your customers save money and make a larger share of their wallet available to you. One observation for ISVs: IBM’s actions are not in your best interest. We are happy to work with distributors to ease that process, work together on the content of Oracle Linux, and ensure Oracle software products are certified on your distribution.īy the way, if you are a Linux developer who disagrees with IBM’s actions and you believe in Linux freedom the way we do, we are hiring. Furthermore, Oracle welcomes downstream distributions of every kind, community and commercial. Oracle makes the following promise: as long as Oracle distributes Linux, Oracle will make the binaries and source code for that distribution publicly and freely available. "We want to emphasize to Linux developers, Linux customers, and Linux distributors that Oracle is committed to Linux freedom. The Oracle announcement also goes on to add: If an incompatibility does affect a customer or ISV, Oracle will work to remediate the problem." From a practical standpoint, we believe Oracle Linux will remain as compatible as it has always been through release 9.2, but after that, there may be a greater chance for a compatibility issue to arise. In the past, Oracle’s access to published RHEL source has been important for maintaining that compatibility. Oracle Linux will continue to be RHEL compatible to the extent we can make it so. We will continue to develop and test our software products on Oracle Linux. "As for Oracle, we will continue pursuing our goal for Linux as transparently and openly as we always have while minimizing fragmentation. In that post they note Oracle intends to continue working on Oracle Linux and still making it compatible with upstream Red Hat Enterprise Linux without noting what steps they may take to obtain the sources moving forward. Oracle Linux has improved over the years and beyond being RHEL-compatible have worked on other features like their Unbreakable Enterprise Kernel. The release was issued by Edward Screven, Chief Corporate Architect at Oracle, and Wim Coekaerts, Head of Oracle Linux Development. There is an Oracle press release today entitled Keep Linux Open and Free-We Can’t Afford Not To. We've been waiting for Oracle to comment on their plans for the RHEL-compatible Oracle Linux distribution and today they finally issued a statement. Following the stunning decision last month by IBM that they would begin limiting access to the Red Hat Enterprise Linux sources, AlmaLinux quickly came out working on a path forward and Rocky Linux also shared some ideas how they may continue providing a RHEL-compatible Linux distribution.
