Kubernetes -- Introduction to common plug-ins of kubernetes

One 、 Network and network strategy

• ACI
  adopt Cisco ACI Provide integrated container network and security network .
• Antrea
  In the 3/4 Layer execution , by Kubernetes Provide network connection and security services .Antrea utilize Open vSwitch As the data side of the network .
• Calico
  It's a safe L3 Network and network policy driven .
• Canal
  combination Flannel and Calico, Provide network and network strategy .
• Cilium
  It's a L3 Network and network policy plug-ins , Be able to implement transparently HTTP/API/L7 Strategy . It also supports routing （routing） And coverage / encapsulation （overlay/encapsulation） Pattern .
• CNI-Genie
  send Kubernetes Seamless connection to a CNI plug-in unit , for example ：Flannel、Calico、Canal、Romana perhaps Weave.
• Contrail
  be based on Tungsten Fabric Of Contrail It is an open source multi cloud network virtualization and policy management platform ,Contrail and Tungsten * Fabric And business process system （ for example Kubernetes、OpenShift、OpenStack and Mesos） Integrate together , For virtual machines 、 Container or Pod And bare metal workloads provide isolation mode .
• Flannel
  Is one that can be used for Kubernetes Of overlay Network providers .
• Knitter
  Is for kubernetes Network components that provide composite network solutions .
• Multus
  Is a multi plug-in , Can be found in Kubernetes Provides a variety of network support , To support all CNI plug-in unit （ for example Calico,Cilium,Contiv,Flannel）, And included in Kubernetes Based on SRIOV、DPDK、OVS-DPDK and VPP Workload for .
• OVN-Kubernetes
  It's a Kubernetes Network driven , be based on OVN（Open Virtual Network） Realization , It's from Open vSwitch (OVS) The virtual network implementation derived from the project . OVN-Kubernetes by Kubernetes Provide network implementation based on overlay network , Include one based on OVS Implemented load balancer And network strategy .
• OVN4NFV-K8S-Plugin
  It's based on OVN Of CNI Controller plug-in , Provide cloud based native service function chain （Service Function Chaining,SFC）、 Varied OVN Cover The Internet 、 Dynamic subnet creation 、 Dynamic virtual network creation 、VLAN Drive network 、 Direct drive network , And you can Connect to other multi network plug-ins , For edge based 、 Cloud native workload with multi cluster networking .
• NSX-T
  Container plug-ins （NCP） Provides VMware NSX-T With container coordinator （ for example Kubernetes） Integration between , as well as NSX-T And container based CaaS / PaaS platform （ For example, key container services （PKS） and OpenShift） Integration between .
• Nuage
  It's a SDN platform , Can be found in Kubernetes Pods He Fei Kubernetes Provide policy based networking between environments , And has visualization and safety monitoring .
• Romana
  It's a pod The third layer solution of the network , And support NetworkPolicy API. Kubeadm add-on Installation details can be found here .
• Weave Net
  Provide networks and network policies that work at both ends of the network packet , And there's no need for additional databases

Two 、 Service discovery

• CoreDNS
  It's flexible , Extensible DNS The server , Sure Installed as a in the cluster Pod Provide DNS service

3、 ... and 、 Visual management

• Dashboard
  It's a Kubernetes Of Web Console interface .
• Weave Scope
  It's a graphical tool , Used to view your container 、Pod、 Service etc. . Please talk to one Weave Cloud account number Use it together , Or run it yourself UI.

Four 、 Foundation setup

• KubeVirt
  You can make Kubernetes Running virtual machines add-ons. It usually runs on a bare metal cluster .
• Node problem detector
  stay Linux Run on node , And report system problems as events Or node status
