Jenkinsfile allows defining pipelines as code using a groovy DSL syntax and checking it into source version control which allows you to track, review, audit and manage the lifecycle of changes to the continuous delivery pipelines the same way that you manage the source code of your application. Although the groovy DSL syntax which...

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...

vSphere Cloud provider and VMDK dynamic provisioning

davis phillips

The release of OpenShift Container Platform 3.6 brings support for vsphere cloud provider. This provides vsphere VMDK dynamic provisioning for persistent volumes for container workloads. The storage presented to vsphere virtual machines as a VMDK has ReadWriteOnce access mode. In the OCP 3.6 on vSphere reference architecture, much of this process is automated and can be implemented easily. Virtual Machine Disks or VMDKs exists in virtual machines. Configuring the OCP cluster for vsphere cloud provider support requires: Master Node Configuration...

Connecting Kubernetes and Docker

Nikhil Chawla

This blog to help my fellow developers who are working on "Docker" and " Kubernetes" simultaneously. Because, they know that Kubernetes runs over docker-engine but there is a catch, that: 1. Containers running on Docker, and 2. Containers running inside of a Kubernetes Pod, are absolutely running isolated, without even knowing each other's existence. But, we are developers, so there are chances where we might come across a situation where we desperately need to let the Docker formatted containers communicate...
