Red Hat Summit Spotlight: Getting Started with Cloud-Native Apps Lab

Siamak Sadeghianfar

Cloud-native application development is the new paradigm for building applications and although is it often mistaken for microservices, it is much more than that and encompasses not only the application architecture but also the process through which applications are built, deployed, and managed.

Wiping the Slate Clean with the OpenShift Container Platform

Benjamin Holmes

With traditional virtualized infrastructure or Infrastructure-as-a-Service, it is common practice to regularly refresh instances back to a known good state. This provides confidence that the application workloads have the correct runtime configuration, no deltas are being introduced, and they can be relied upon to provide value for the business. In these cases, you might use tools such as Ansible or Jenkins, but when we move our application workloads to containers running on OpenShift Container Platform, we can use native tools...

How to configure persistent storage with OpenShift or Kubernetes for development environment

Chandra Shekhar Pandey

We know that containers in Openshift or Kubernetes don't persist data. Every time we start an application, it is started in a new container with an immutable Docker image. Hence, any persisted data in the file systems is lost when the container stops. Hence if an application or container is rebuilt or restarted than we can't view previous logs or if we are using containers with mysql or any other database then schema, tables, and all data will be lost...
