We can now execute the installation with a simple command (if you want, you can specify the debug log level in order to have a better understanding of the installation process): During the installation, log into the OpenStack dashboard (shown in Figure 3) and you’ll see that OpenShift IPI takes care of everything; from spawning new instances, to building a dedicated tenant network, configuring security groups, and so on so forth. That being said, some basic steps are provided. Octavia is not a strict requirement unless you are using Kuryr. OpenStack is an IaaS while OpenShift is a PaaS. Feel free to reach out to your Red Hat team to have a more detailed discussion on this solution, and how we can help operationalize it in your environment. After this basic setup, I installed the undercloud, imported and introspected the OpenStack nodes, and then built my OSP templates to successfully deploy my overcloud: I skipped the overcloud endpoint TLS configuration because, at the time of this writing, Red Hat OpenShift Container Platform 4.2 cannot be installed via Installer Provisioned Installation (IPI) on Red Hat OpenStack Platform when the endpoints are encrypted with self-signed certificates (as highlighted in this knowledge base entry). The full prerequisites for OpenShift 4.2 IPI on OpenStack are available here. Take a look at this: Those ports are not attached to an instance. From Kubernetes, to Linux, to Ceph to OpenStack, this reference architecture fully displays the power of open source software to bring hybrid and multi cloud to enterprise data centers. Using OpenShift on OpenStack, Red Hat Customers Power Infrastructure and Application Modernization. In addition, I have also tried adding OpenStack Neutron ports to OpenShift nodes and attaching a provider network in order to have a dedicated management network with static IP/routes. Categories. The main concern to me was that I didn’t have enough bare-metal nodes to build my environment. OpenStack and Kubernetes-based hybrid cloud solutions accelerate business transformation through container-based application development and tightly integrated cloud technologies. Its server requirements are: Note: You could use SSDs for every VM, but I had to balance my needs with hardware availability. The first is in the [neutron] section, setting a timeout value (in my case 300 seconds) big enough to avoid timeouts on the Neutron side when nova spawns a new instance: The second is in the  [default] section, setting a timeout value (in my case 300 seconds) big enough to avoid timeouts on the Neutron side when nova tries to attach a Virtual Interface (VIF) to a new instance: After these edits, you would restart the nova_libvirt container on the compute node. You can then start playing around to test the capabilities this environment can grant to your organization. CentOS 7.2 cloud image (we leverage cloud-init) loaded in Glance for OpenShift Origin Deployments. The key targeted use cases for this solution are software developer cloud, web, mobile, AI/ML, and predictive analytics workloads. Why OpenShift on OpenStack? With Red Hat OpenShift Container Platform on Red Hat OpenStack Platform, both the Infrastructure-as-a-Service (IaaS) and Container-as-a-Service (CaaS) layers are automated, designed to provide integrated consistency through the product stack and improved datacenter management efficiency. Other OpenShift reference architectures, including those for previous versions of OpenShift on OpenStack, can be found, Red Hat Wins Stratus Cloud Compute Awards, OpenShift Container Platform and the Essential Eight. Alex Handy. This solution is built on proven enterprise open source technologies that are supported by Red Hat. Cisco Application Centric Infrastructure (ACI) supports Red Hat OpenShift 4.5 nested in Red Hat OpenStack Platform (OSP) 13. In this case, it is the second half of the range identified in the first parameter (openshift_openstack_kuryr_service_subnet_cidr). This step is needed because the IPI installer takes care of configuring a Keepalived pod on every master and worker, exposing the virtual IPs (VIPs) that route traffic to internal APIs, the Ingress, and DNS services. Red Hat® OpenShift® is an enterprise-ready Kubernetes container platform with full-stack automated operations to manage hybrid cloud, multicloud, and edge deployments. At deployment, all OpenShift Container Platform machines are created in a Red Hat OpenStack Platform (RHOSP)-tenant network. Get to know Ask OpenStack Resources for moderators. Running OpenShift on Heat Overview. At the end of the installation, we will have one OpenShift cluster running on seven OpenStack Virtual Machines: 3 x OpenShift masters VMs; 3 x OpenShift workers for CPU workloads VMs Disqus is used to facilitate comments on individual blog posts. In addition, DHCP was disabled on the default (pre-existing) libvirt network because the director assigns IPs during OpenStack setup. This contest awards innovators and leaders in the cloud compute business, and Red Hat was ... Red Hat OpenShift Container Platform provides a feature-rich CLI based on the kubectl command. If the API and Ingress port on Neutron are down, how does this setup work? The OpenShift CLI (oc) is mainly used to interact with the API ... What do the planets of the solar system and Australian cybersecurity strategies have in common? I’d like to thank Daniel Bellantuono for sharing helpful tips about OpenStack’s architecture. It's straightforward to deploy it on top of the Infrastructure as a Service platform OpenStack using Heat templates, in a way which allows it to grow as more resources are required. There are eight of them! Large IT organizations are increasingly looking to develop innovative software applications in hybrid and multi clouds architectures. Place this file in the directory you will run the openshift-install from. … We serve the builders. That effort pushed me to publish this article so I can share and explain how I tested an OpenShift 4.2 IPI setup on OpenStack 13 with a single Red Hat Enterprise Linux (RHEL) server. Instead, they are created on the tenant network to be used by OpenShift to allocate VIPs via Keepalived or the Virtual Router Redundancy Protocol (VRRP) in order to load balance the internal services (API and DNS) exposed by masters and the Ingress requests exposed by workers (ingress pod = OpenShift router). Let’s assign our FIP in order to reach the OpenShift console. OpenShift on OpenStack The principal purpose of the OpenShift on OpenStack Special Interest Group is to discuss, develop and disseminate best practices for deploying and managing OpenShift on OpenStack. You probably had to make two edits in the nova_libvirt container configuration file (/var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf). Digging into our OpenShift setup, the project openshift-openstack-infra contains three haproxy and three keepalived pods running on masters plus two keepalived running on workers: Looking at one of these pods running on master nodes, we can see that Keepalived was configured to use the VRRP protocol to expose three VIPs: For instance, in order to route Ingress traffic to internal API ports, there is a VRRP instance with a VIP assigned (10.0.0.5): Looking at the haproxy pod on the master, we can see that it listens on port 7443 on all IPs, and that it balances the API calls to the masters’ nodes (section backend masters): Logging via SSH to the CoresOS node (master-0) to double-check, we can see that haproxy is listening on port 7443: The VIP (10.0.0.5) instead is assigned right now to master-2 node which is the master from a Keepalived perspective: What is missing? OpenShift is the only way to truly get multi-cloud, enterprise Kubernetes. The second FIP association is, instead, managed by us as we saw previously in order to reach OpenShift console and other services: Looking at the Neutron ports, we can see that, as suspected, those ports are API and Ingress but they are down. To simulate the existing customer environment. July 1, 2019 | by Therefore, they are not accessible directly in most RHOSP deployments. I am very excited to announce that we have published a new Reference Architecture that showcases the power of running Red Hat OpenShift Container Platform on top of Red Hat OpenStack Platform, Red Hat Enterprise Linux and Red Hat Ceph Storage. There are a number of advantages to combining these two solutions: OpenShift Installer Provisioned Infrastructure (IPI) was released with OpenShift 4.2. Brainstorming led me to start my journey toward testing OpenShift 4.2 setup on OpenStack 13 in order to reply to the customer and leverage this effort to build a demo video for Red Hat Forum. Therefore, they are not accessible directly in most RHOSP deployments. edit flag offensive delete link more add a comment. parameters: roles: openshift_on_openstack. I ran into many timeout issues but finally, I found the right tuning to apply. But now, we have operator framework, which does make statefull containers a very valid choice, so I'm looking at adding some object storage. OpenShift is a Platform as a Service. Details about how we use cookies and how you may disable them are set out in our Privacy Statement. A standard high-availability (HA) OpenStack environment is composed of: My goal was to build the following to host OpenShift 4.2 and simulate an HA environment at the control plane and storage level: Why? Today organizations have an … The CLI is invoked via the oc command. Now, let’s dig into the different layers. When using HEAT template to create OpenShift, public endpoint was specified for --parameter os_auth_url. You can configure OpenShift Container Platform API and application access by using floating IP addresses (FIPs) during installation. Unfortunately, I was not able to accomplish this goal because IPI’s goal is to provide an opinionated setup. that showcases the power of running Red Hat OpenShift Container Platform on top of Red Hat OpenStack Platform, Red Hat Enterprise Linux and Red Hat Ceph Storage. So, how can load balancing work? I had an idea: To see if I can set up everything with just a single bare metal server. Here is the demo video we recorded with my colleague Rinaldo Bergamini. OpenStack provides a programmatic API-driven approach for OpenShift. It works because on the Neutron ports assigned to masters and workers, keepalive VIPs are allowed from a port security perspective. Figure 4: Your OpenStack network topology. You can also use the oc client from the client machine used to install OpenShift (in my case, it was my undercloud VM): There is only one post-deployment command required in order to attach a pre-allocated floating IP address (FIP) to the Ingress port. What follows are a couple of tips and tricks regarding OpenStack compute node timeout tuning. This procedure and the resulting architecture are not supported (and not even suggested) by Red Hat. OpenShift is a Platform as a Service (PaaS) application platform.. The guide below can be used to demonstrate launching a single-instance OpenShift implementation (a broker and node on one instance), via a heat template.. OpenShift on OpenStack 1. The idea here with OpenStack is to deliver the on-premise portion of multi-cloud, with the same capabilities as public cloud. At the same time, the Italian solution architect “Top Gun Team” was in charge of preparing speeches and demos for the Italian Red Hat Forum (also known as Open Source Day) for the Rome and Milan dates. November 10, 2020. If you want to redeploy your overcloud later, you’ll have to customize nova.conf via a custom puppet configuration executed by OpenStack director. At deployment, all OpenShift Container Platform machines are created in a Red Hat OpenStack Platform (RHOSP)-tenant network. Figure 5: Your new cluster in Red Hat OpenShift Container Platform. Deploy OpenShift on OpenStack. The first one (eth0) is attached to the provisioning network in order to successfully deploy overcloud nodes, and the second (eth1) is attached to the default network in order to reach (via the NAT made by the L0 hypervisor) the internet to download the RPM packages needed for the setup: The setup for other VMs is similar, with the only difference being the amount of resources involved (such as RAM and CPU) and the NIC configuration. Figure 3: The OpenStack dashboard lets you watch the installation process in action. Yes, both OpenShift Origin and OpenShift Container Platform can be deployed on OpenStack. security and compliance, data affinity, performance, etc.). Instead, when User-Provisioned Infrastructure (UPI) is available for Red Hat OpenStack, this addition will give us this option. OpenStack Prerequisites. Stats. This article assumes that you have a basic knowledge and understanding of OpenStack architecture. OpenShift its self needs to be configured for OpenStack to make use of storage and other services provided by OpenStack. OpenShift 4.2 on Red Hat OpenStack Platform 13 + GPU Red Hat OpenShift Container Platform 4.2 introduces the general availability of full-stack automated deployments on OpenStack. OpenShift Container Platform, OpenStack Platform < Back to the blog. We use cookies on our websites to deliver our online services. Thirty minutes later, you’ll have your OpenShift cluster up and running on OpenStack. Ask Question Asked 4 years ago. You can run it on public cloud, virtualization, baremetal or anything that can boot Red Hat Enterprise Linux. This solution is built on proven enterprise open source technologies that are supported by Red Hat. Manage hybrid cloud, multicloud, and edge deployments. $ openstack role add --user operator --project operators swiftoperator. VMs were defined using qemu-img, virt-customize, and virt-install starting from the Red Hat Enterprise Linux 7 KVM guest image downloadable from the Red Hat Customer Portal: Director needs to have two NICs. At deployment, all OpenShift Container Platform machines are created in a Red Hat OpenStack Platform (RHOSP)-tenant network. Therefore, the results are this: Here is the resulting overcloud server list: Because of the limited hardware capabilities (and over-committing, too, given that we are talking about one single bare-metal server), I executed many tests in order to successfully deploy OpenShift on OpenStack. If you ever get to more then 10 servers, consider OpenStack. See Figure 5 for the results in the Red Hat OpenShift Container Platform. Doing this was possible because RHEL is properly tuned to use nested virtualization with KVM. OpenStack Platform. OpenShift, of course, is infrastructure independent. We will use the openshift-installer binary to spawn the OpenShift cluster on OpenStack. Red Hat OpenShift is optimized to improve developer productivity and promote innovation. OpenStack and OpenShift don't overlap at all. We use cookies on our websites to deliver our online services. As a result, our external network on the OpenStack side will use the default network on the L0 hypervisor. openshift_openstack_kuryr_service_pool_start: The start of the range to be used by the Octavia load balancer Amphora VM IPs. Last, but not least, we need to configure our hypervisor to use an Ironic project driver. Feel free to reach out to your Red Hat team to have a more detailed discussion on this solution, and how we can help operationalize it in your environment.

Other OpenShift reference architectures, including those for previous versions of OpenShift on OpenStack, can be found here. This configuration is used by the undercloud to perform node introspection and setup via PXE and TFTP. (Sorry, Pluto). To enable this support, Cisco ACI provides customized Ansible modules to complement the upstream OpenShift installer. As you may already know, the entire OS setup and configuration for OpenStack nodes (VMs in our case) is managed by the Red Hat OpenStack Platform director. It looks like this: To summarize Ingress traffic flow for incoming HTTP/HTTPS requests: Note: This page explains IPI networking infrastructure with a good level of detail. You can configure the OpenShift Container Platform API to … The L0 bare metal node was configured with Red Hat Enterprise Linux and KVM to act as a hypervisor. Details can be found in the official docs here. In addition, I included a floating IP (FIP) for the internal API load balancer (lbFloatingIP)—this FIP grants access to the internal LB (API load balancer): You may also notice that I didn’t use Octavia (an OpenStack load balancer-as-a-service) because, in my own test, I specifically want to simulate a customer environment where Octavia is not used. By using this website you agree to our use of cookies. OpenShift is a Paas (Platform as a service) that runs above the existing cloud services offered by AWS, Google Cloud Platform, etc. This private cloud should be simple, agile, flexible, secure, cost efficient, and a key part of their overall Hybrid and Multi cloud architecture. Join us if you’re a developer, software engineer, web designer, front-end designer, UX designer, computer scientist, architect, tester, product manager, project manager or team lead. For ensuring site stability and functionality. For the overcloud nodes, I added two additional NICs (Figure 1’s orange section) because I wanted a bond inside Open vSwitch. There is a reference architecture as well as a set of Heat templates to automate the process.. All organizations definitely want and will use the public cloud but likely will also want to maintain control, avoiding lock-in. 200 GB SAS disk (to host medium-performance VM disks, namely the undercloud disk and the controller disks). OpenShift on OpenStack. Thus, OpenShift can be used as a cloud-based service on OpenStack. Red Hat OpenShift. After a while (about 30 minutes) you’ll have your Red Hat OpenShift 4.2 cluster up and running, as you can see here: Looking at OpenStack network topology in Figure 4, you’ll see the resulting architecture. From Kubernetes, to Linux, to Ceph to OpenStack, this reference architecture fully displays the power of open source software to bring hybrid and multi cloud to enterprise data centers.

The key architecture components of the solution are: A range of testing was performed in the Red Hat labs to validate these design and deployment best practices, aiming to help you achieve faster time to business value. The Essential Eight is a set of baseline recommendations ... New OpenShift on OpenStack Reference Architecture, I am very excited to announce that we have published a new. In your deployment you also need to set the following parameter for DNS servers on neutron networks. You use OpenStack on top of existing resources, either on-premises or in the cloud, to create a unified cloud. I don’t want to go deeper into the details of OpenStack setup because the process is long and difficult to summarize. This new reference architecture demonstrates a private cloud solution for enterprise, telco IT, government, and IT service providers that desire a private cloud with programmable Infrastructure as a Service (IaaS), Containers as a Service (CaaS), and Platform as a Service (PaaS) capabilities. As you may know, IPI on OpenShift 4.2 also supports Red Hat OpenStack Platform 13 as a provider, leveraging OpenStack’s virtualization capabilities to host OpenShift nodes. With OpenShift 4.2, containers can be managed across multiple public and private clouds, including OpenStack. For instance, you can scale your OpenShift worker nodes via MachineSet by calling the OpenStack API with a single click. Figure one shows a schema summarizing the whole setup. In addition to those nodes (VMs in my case), I of course had to consider the list of requirements needed by IPI in terms of vCPU, RAM, floating IPs, and the security groups to be available at the tenant level. The virsh command shows the rest of the bare metal node’s specs: Next, I used the tuned command to perform network latency workload tuning at the L0 level: In order to successfully configure and deploy your overcloud nodes, you need to do two things. RHOSP 13 is a special release for Red Hat because it is our current long term supported OpenStack release. This new reference architecture demonstrates a private cloud solution for enterprise, telco IT, government, and IT service providers that desire a private cloud with programmable Infrastructure as a Service (IaaS), Containers as a Service (CaaS), and Platform as a Service (PaaS) capabilities. This is possible because both technologies are independent of each other. We're pleased to share the news that Red Hat has won two of the 2020 Stratus Awards for Cloud Computing. A lot of these applications have to be developed and deployed in an on-premises private cloud for various reasons (e.g. The openshift-installer binary is directly consuming the OpenStack API. Warning: This article was written to help customers, partners, and community members test OpenShift 4.2 on OpenStack 13 only for demo/test purposes. Keep reading. The key targeted use cases for this solution are software developer cloud, web, mobile, AI/ML, and predictive analytics workloads. Question Tools Follow 1 follower subscribe to rss feed. Within this bond, I configured the OpenStack networks (namely InternalApi, Tenant Network, Storage, and Storage Management) with the tag vlan and left the external network untagged. With your free Red Hat Developer program membership, unlock our library of cheat sheets and ebooks on next-generation application development. You can configure the OpenShift Container Platform API to … We need to assign it to the ingress-port: Finally, I updated my host file in order to reach OpenShift via FQDN so I didn’t have to configure a DNS service: That’s it. In contrast, OpenShift is a platform as a service (PaaS) that operates independently of cloud resources through containerization. The objectives for the new installer are to provision and configure OpenShift 4.2 in a fully automated and opinionated way, making it easy to get started on day one and granting you more time to focus on your team on day two. Second, you have to define your virtual machines. My choice was to use VirtualBMC to simulate Intelligent Platform Management Interfaces (IPMIs) that are not available in a virtual machine environment. Months ago, a customer asked me about Red Hat OpenShift on OpenStack, especially regarding the network configuration options available in OpenShift at the node level. Deploy OpenShift on VM's , use that for containers, and virtualization for VM's. Note: If you want to skip the bits and bytes, skip ahead to the “Demo” section. This setting allows incoming traffic from different IPs on the same Neutron port: Need to summarize the traffic flow for incoming API traffic? Other OpenShift reference architectures, including those for previous versions of OpenShift on OpenStack, can be found here. OpenStack is compatible with cloud providers, including Azure, AWS, Google Cloud, and Digital Ocean. As you saw, we preallocated two FIPs within our tenant using the bash script I shared in the section “L2 nested virtual machines (OpenShift nodes),” in the lines: These two FIPS are associated with two Neutron ports, namely api-port (internal IP 10.0.0.5) and the Ingress port (internal IP 10.0.0.7). For this reason, I created a dedicated network called “provisioning” (Figure 1’s blue section) to attach to all of my VMs. Use OpenStack as the provider with the flavor “master” (created by the script. I used just a single bare-metal node (L0) and then, using KVM’s nested virtualization features, created a deployment of OpenStack nodes (L1) with virtualized OpenShift nodes (L2) on top. Active 4 years ago. Be aware that these changes are applied to the OpenStack Nova container after a container restart. Here is a snippet of network config at the L0 level: The provisioning network is usually a pre-existing datacenter network in a native VLAN configuration. Need to disable anti-MAC spoofing only for particular IPs/MACs? The problem solvers who create careers with code. 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. Assign the swiftoperator role to the OpenStack user. The Reference Architecture 2017 - Deploying Red Hat OpenShift Container Platform 3.4 on Red Hat OpenStack Platform 10 derives from the Redhat OpenShift on OpenStack Github repo provides the orchestration templates to stand up a infrastructure stack to run OpenShift on. This presentation gives an overview of what OpenShift gives to developers, and how to deploy it on top of OpenStack. OpenShift on OpenStack is integrated with Nova, Cinder, Swift, Octavia, Kuryr, etc. First, you need to define a provisioning network on libvirt for the undercloud to use when installing our overcloud nodes via PXE. The start of that range is 192.168.160.0. Because I’ve tested the setup many times and I didn’t want to worry about prerequisites every time I executed a setup, I made a simple bash script to prepare my tenant on OpenStack: Now that the prerequisites are here, let us look at our install-config.yam file, which will instruct the IPI installer about OpenShift configuration in terms of the number of nodes, flavor to be used, network CIDR, etc. And TFTP in a practical way and compliance, data affinity, performance, etc..!
