While all the components we use here are definitely supported, this particular combination is untested by our engineering, QE, and performance teams. If you have any questions, please reach out to your Red Hat sales and support teams. Don’t consider anything here a recommendation for how you should run your environment, only an academic study of a possible approach to solving an interesting challenge. There’s a pretty good chance that this architecture is not explicitly supported by Red Hat.
The heketi-cli needs to run $somewhere. With the container running with networking in host mode, heketi is listening on localhost port 8080. For simplicity, the RPM is installed on node1. Export the environment variable in order to be able to run heketi-cli commands.
If the user, for performance or cost reasons, wants the GlusterFS storage layer outside of OpenShift, this is made possible with CRS. The reference architecture also incorporates the concept of Container-Ready Storage (CRS). For this purpose, the reference architecture ships add-crs-storage. The difference is that these instances are not part of the OpenShift cluster. Py to automate the deployment in the same way as for CNS. In this deployment flavor, GlusterFS runs on dedicated EC2 instances with a heketi-instance deployed separately, both running without containers as ordinary system services. The storage service is, however, made available to, and used by, OpenShift in the same way.
How to port forward using xinetd on CentOS.
AWS, Google, and Azure are all examples of DIY businesses. We’ll label them “Assisted DIY. We’ll call them “Pre-packaged. Their large investments in in-house expertise allows them to convert raw technologies into solutions with limited pre-integration by technology suppliers. As noted in the following figure, a few companies with large staffs of in-house experts can create composable infrastructures from raw technologies. A larger number of other companies, also needing composable infrastructures, rely on technology suppliers and the community for solution pre-integration and guidance to reduce their in-house expertise costs. ” Finally, the majority of global enterprises lack the in-house expertise for deploying these composable infrastructures. They rely on public cloud providers and pre-packaged solutions for their infrastructure needs.
They will simply get the right information from the existing CloudFormation stack to retrieve the proper integration points. These are picked up by the playbooks to further reduce the information needed from the administrator. In addition, compared to previous releases, the CloudFormation templates now emit more information as part of the output.
Just check /etc/ xinetd. D/ for the servers that are under xinetd and set to . Xinetd and standalone servers can coexist without problems.

So you’re heeding all the advice here, and you’re going to deploy 12 Red Hat Gluster Storage nodes in an optimal architecture for 150 NFS clients. We’re more than happy to support the NFS client, but you should know what you’re getting into. Well, hold on there a minute, buckaroo.
