For over six months, since the release of RHOCP 4.2, we have supported deploying RHOCP 4 on-premises with Red Hat OpenStack Platform (RHOSP). We encourage you to download the architecture and spend some time reviewing the entire document. Discusses considerations for DNS, security, and critical resources management. Red Hat OpenShift is an open source container application platform based on the Kubernetes container orchestrator for enterprise application development and deployment. That’s right, we took our combined experiences, across internal teams and customers, to ensure an integrated solution that passes the same rigorous tests required of our software’s individual components. The openshift-install tool leverages Terraform to produce Installer Provisioned Infrastructure. How-tos, With OpenShift 4.2, containers can be managed across multiple public and private clouds, including OpenStack. This is possible because both technologies are independent of each other. Checks if an external network has been configured on the overcloud as required for an OpenShift deployment on top of OpenStack. Working closely with our global Quality Engineering teams, we tested the solution. Modern applications need resources from multiple infrastructures. The issu… 1 Running OpenShift on Heat. parameters: roles: openshift_on_openstack. The API load balancer floating IP should also go into the install-config.yaml at /openstack/lbFloatingIP.There is more to be said on the install config later.. OpenShift Installer Provisioned Infrastructure (IPI) was … hosts: undercloud. Create user shiftstack with role swiftoperator and temp URL ability, The OpenShift installer takes advantage of OpenStack Neutron featues including. Two main factors are really pushing a re-emergence of interest in OpenStack and that is containers and cloud. This is all good now, but must you make your CA cert available in two ways. Even though OpenShift 4.3 was announced with OpenStack support, there have been a lot of issues that affect clouds using self-signed certificates for their OpenStack endpoint. In this new episode, we will configure in HA Openshift 3.7 (only the API) using VRRP in Red Hat OpenStack Platform 10. groups: openshift-on-openstack.

Wednesday, November 14, 4:50pm-5:00pm (3:50pm - 4… Thus, OpenShift can be used as a cloud-based service on OpenStack. Rather then building machines and running an Ansible playbook to configure them you now have the option of setting a fewer paramters in an install config running an installer to build and configure the cluster from scratch. We will deploy OpenShift 4.2 on OpenStack. Remember when we had the discussions about pets vs cattle? I need one on one live instructions to get the all projects done. 3. OpenStack offers minimal support for containers and instead focuses on VMs based on KVM, Xen, and VMWare hypervisors. Although OpenShift and OpenStack offer many of the same capabilities, there are some differences you should consider before choosing a platform. Important! Before starting the installation process we must establish 2 IP addresses which will be used to access the OpenShift cluster externally. While preparing for a couple recent presentations, I wanted to experiment with the automated installation of OpenShift Container Platform (OCP) 4.2 on top of an existing Red Hat OpenStack Platform (RHOSP) 13 deployment.

In that case ensure that ca.crt.pem is placed in the current working directory when you run the openshift-install command. Active 4 years ago. If you are still using RHOCP 3.11, you need to continue to reference the RHOCP 3.11 document, because the RHOCP 3 and 4 releases and the integrations with RHOSP are significantly different. August Simonelli. OpenShift on OpenStack is co-engineered by Red Hat, which means having aligned product roadmaps and integration tests created by the Red Hat engineers working on these projects every single day. The installer will create a private node network 10.0.0.0/24 and a router joining this network to the external network you identify as holding your floating IPs. Finally while the association of the API floating IP to the API port is automatically handled by the installer process, the ingress floating IP must be assocated by hand. The install process will delete your install-config.yaml! With RHOCP 4.2 and 4.3, Red Hat support and consulting teams have been working closely with customers improving the integration of these two great platforms.

OpenShift on OpenStack 1. Integrates RHOSP director-deployed Red Hat Ceph Storage with RHOCP providing all storage including, volumes, registry, and instance storage. This node will be configured to run a tiny 1 node OpenShift cluster, which only exists as a mechanism to serve out the configurations required by the actual cluster being built shortly after. And where we will run the installer. Utilizes the Full Stack Automation installation method for RHOCP on RHOSP. It’s a result and implication of acquisition of CoreOS by Red Hat announced at the beginning of 2018. One is within the install-config. We like to think of this document as the “on-premises starting point” in your Hybrid Cloud journey with some real-world implementation examples that allow you to see how components can be implemented together as an integrated and supported solution.

We aim to show how the integrated solution can be achieved based on our specific selections from the many solution choices reviewed in part one. At the moment the last releases are OCP 3.6 and OSP 11. In addition to the 2 floating IPs we created, the installer creates 3 Neutron ports to serve as holders of the highly available cluster virtual IPs which provide three functions. The Bare Metal IPI Networking Infrastructure doc is also highly relevant. The API load balancer floating IP should also go into the install-config.yaml at /openstack/lbFloatingIP. First create an OpenStack project and user. And here is a look at the final port and FIP assignments. To customize the installation, modify parameters in the install-config.yaml before you install the cluster. OpenStack Platform, These notes are based on recent 4.4 nightly builds on OSP 13 Queens.
