Managing the Lifecycle of OpenShift Clusters: Vetting OpenShift Installations

Whether installing a new release of a software package or just installing an update (such as a bug fix), it is wise to perform tests against the newly installed software in order to confirm that it is performing correctly in the target environment. This is especially true with OpenShift since it contains a number of open source components and can be deployed to a variety of environments, such as an on-prem datacenter, or a public or private cloud.

Enhancing your Builds on OpenShift: Chaining Builds

Enhancing your Builds on OpenShift: Chaining Builds

In addition to the typical scenario of using source code as the input to a build, OpenShift build capabilities provides another build input type called “Image source”, that will stream content from one image (source) into another (destination).

Using this, we can combine source from one or multiple source images. And we can pass one or multiple files and/or folders from a source image to a destination image. Once the destination image has been built it will be pushed into the registry (or an external registry), and will be ready to be deployed.

What’s New in OpenShift 3.5 – Cluster Management

What’s New in OpenShift 3.5 – Cluster Management

One of the things I hear while visiting customers is how much they love the fact we continue to release new software features in OpenShift at the pace of one release every quarter. OpenShift Container Platform 3.5 is now our 6th “minor” release of OpenShift with countless errata releases (on average about every 3 weeks) since 2015. What you might have not noticed, is the fact all our OpenShift and RHEL engineers are pulling double duty during releases. While we were late up at night getting OpenShift 3.5 ready to release, they were also finishing up Kubernetes 1.6. That pace of innovation and passion is only possible by working in an open community.
