This article will explain in detail how containers and Kubernetes solve the pain points of OpenStack lifecycle management. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

OpenStack has been embraced by the Docker container to help simplify its lifecycle management, and it is also looking for ways to run the container itself. OpenStack proponents are adopting containers and container orchestration to help meet the challenges of lifecycle management, as well as the problems of open source cloud computing platforms.

In the case of using Kubernetes, Mitantis has recently successfully run the OpenStack lifecycle management tool in the container. In the future, people will have a wider understanding of the management and evolution of OpenStack in containers, and run its key parts in containers for better release management and evolution techniques.

At present, enterprises mainly run containers internally or on virtual machines, which not only brings enterprises the speed and simplicity of containers, but also familiarizes themselves with VM. "this puts OpenStack in an advantageous position because it can manage virtual machines and containers," said Jay Lyman, research manager for cloud management at 451 Research. Lyman added, "more enterprises want to have the function of network-scale data center operation and maintenance, and they all want to use system containers to run containers on bare metal."

"as openstack migrates to containers, it will be interesting how Openstack handles computing loads in containers, because that's what developers are trying to do to better handle modern applications." Said AI Hilwa, IDC's project director.

"Refactoring Fuel into containers and orchestrating them by Kubernetes is designed to address Openstack's most serious pain point-keeping Openstack running, patching Openstack and updating its organizational structure in a non-intrusive way," said Boris Renski, co-founder of Mitantis.

All this work has been done in the OpenStack upstream and in the Kubernetes community, the code will be open source based on the Apache protocol, and it will be included in Mirantis OpenStack10 and is expected to be available for open source in early 2017.

The OpenStack provider agrees to make changes to the architecture

Other Openstack users say they have adopted a similar architecture to ease the burden on operations: put Openstack lifecycle management into containers and orchestrate them.

"Rackspace, their production-ready OpenStack cloud, recently set a record of 1 billion server hours. Similarly, they modified the 2014 version 9 architecture to a container-based architecture and maintained the original style of OpenStack." Bryan Thompson, general manager of OpenStack (Rackspace) Private Cloud, a company that manages cloud computing, is located in San Antonio. Deployment to a standard LXD container helps reduce the complexity of OpenStack deployment while scaling in a replicable and consistent manner. At the same time, it also allows Rackspace to optimize OpenStack, scale Glance and Neutron independently, and then dismantle it.

"using the container framework can reduce barriers to entering and using OpenStack and reduce the aggressiveness of upgrade operations," Thompson said.

"IBM has synchronized with the Kubernetes community, and Blue Box Group Inc, a private cloud company based on OpenStack, has made a core contribution to Mesos and Kubernetes as part of the company's business and is trying to integrate the best features of the hybrid cloud." Said Todd Moore, vice president of open technology at IBM.

So far, containers and virtual machines need to be together.

Move Fuel to Kubernetes so that standards-based technologies can be used to help solve "day-two operation and maintenance problems", such as Docker and Kubernetes, but it also allows users to manage virtual machines on OpenStack or use local Kubernetes API to manage containers. Because container is a relatively new technology, for most enterprises, it is in the early stages of contact. "most cloud native systems are combined with hybrid workload systems, and OpenStack's use of Kubernetes will allow users to run virtual machine and container hybrid systems on OpenStack-Kubernetes." Renski said.

However, running Fuel with Kubernetes emphasizes that OpenStack will start to compete with container platforms and lightweight operating systems, such as CoreOS, according to Lyman. "OpenStac is extensible and can support all these container platforms and lightweight operating systems. This also helps them support containers more fully." Lyman said.

"Kubernetes is not the only option for Mitantis in container orchestration," Lyman said. "in the Tectonic project, CoreOS is not integrated with Kubernetes, and some users are interested in EC2 container services from Mesosphere and Amazon Web Services. The biggest benefit of using Kubernetes is to improve efficiency for IT operations teams, so that these teams can manage more servers, more virtual machines and infrastructure with fewer people." He said.

"A lot of companies are looking for places where they need flexibility, and they are beginning to realize that they can't have a top IT operation and maintenance team." He said.

This is the end of the pain points about how containers and Kubernetes solve the OpenStack lifecycle management. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
