The previous section deployed CIRROS-VM1 to First_local_net, and today we will deploy CIRROS-VM2 to the same network and create second_local_net.connecting a second instance to first_local_netIn the same way launch instance "CIRROS-VM2", the assigned IP is 172.16.1.4.The CIRROS-VM2 is also schedule to the control node, and the output of Ovs-vsctl show is as follows:CIRROS-VM2 for the TAP device is tapddbbb728-93.From CIRROS-VM2 can Ping the IP address of the CIRROS-VM1 172.16.1.3.The network str

Neutron-ns-metadata-proxy: since both Dhcp-agent and l3-agent can create and manage neutron-ns-metadata-proxy, how do you choose to use it?Simply put: Each has its own usage scenarios, and the two schemes can coexist. Let's not worry, we'll discuss it in detail in the following example.The architecture of the Metadata Service has been discussed, and the next section will deepen understanding through practice.650) this.width=650; "Title=" http://7xo6kd.com1.z0.glb.clouddn.com/ Upload-ueditor-ima

queries the ID of the instance, as follows:1) Locate all network subnet with the network ID and then filter out the subnet that the instance IP is located on.2) Locate the port corresponding to the instance IP in the subnet.3) Locate the corresponding instance and its ID via port.③neutron-metadata-agent adds the instance ID to the head of the HTTP request and forwards it to nova-api-metadata so that Nova-api-metadata can return the specified instance It's metadata.instance must first be able to

The request is forwarded to the neutron router. Router forwarded the request to Neutron-ns-metadata-proxy. The following is simple: Neutron-ns-metadata-proxy will request to send neutron-metadata-agent through the UNIX domain socket, which is then sent to nova-ap

I wish I could have my own blockchain practice practiced hand O (∩_∩) o~. But a person, a computer, how to set up the blockchain environment ... It's not easy to say you love a block chain of fire. Don ' t worry! Small series have been addicted to blockchain and smart contracts can not extricate themselves. Now take your hands from

Secret and Configmap support four methods of definition. Pod can choose Volume mode or environment variable mode when using them, but only the Volume mode supports dynamic update.
