Type_drivers = Local,flat,vlan,gre,vxlan This allows us to create all types of networks (although only the local network is created in this section).Both the normal user and the admin can create the network through the CLI or the W

there are no pictures displayed, open the URL to see, it is not true. So, Baidu has some pictures it caches to its own machine, so you can still see, but the actual connection has failedOK, now the automatic download problem solved, then search for pictures according to keywords? Just change the URL, I'll write the code down here. word = raw_input("Input key word: ") ‘http://image.baidu.com/search/flip?tn=baiduimageie=utf-8word=‘+word+‘ct=201326592v=flip‘ result = requests.get(ur

Posture for optionsWhat if there is an "option variable" to represent one or more values at the same time swollen? Then we have to ns_options.For example, there is a simple example:objective-c 12345 typedef ns_options(nsuinteger, jzzpersontype) { jzzpersontypehigh = 0, jzzpersontyperich = 1 0, jzzpersontypepretty = 1 1 }; As you can see, our options here are defined in the way of bitwise operations , and the benefit is that our option variables can be repr

learn Kubernetes in the order of chapters, and Master Kubernetes's theoretical knowledge and practical skills through the experiments in the tutorials. Experienced OPS personnel can use this tutorial as a reference material to view relevant knowledge points in the actual work. It is hoped that readers will be able to lay a solid foundation through this tutorial, to be able to operate the Kubernetes calmly, and to build a practical container management platform in combination with the a

Policy: busybox Pod has no access Service. if Pod added label access: "true" can access the app, but Ping has been banned. The cluster node has no access to the Service, nor does it Ping the replica Pod. The Service cannot be accessed outside the cluster (192.168.56.1). If you want to have the cluster nodes and the outside of the cluster (192.168.56.1) also have access to the application, you can make the following modifications to Network Policy:Apply the new Network P

In the previous section we enable VLAN network in the ML2 configuration, and today we will create vlan100 and discuss the underlying networking changes.Open the menu, Admin, Networks, and click on the "Create Network" button.The Create page is displayed.Provider Network Type Select "VLAN". Physical Network fill in "Default" and must be consistent with Ml2_conf.ini network_vlan_ranges. The segmentation ID, which is the VLAN ID, is set to 100.Click "Create Network" to create a successful vlan100.C

In the previous section we learned the principle of Neutron Vlan Network, and today we discuss how to enable it in the ML2 configuration.The VLAN network related parameters are set first in/etc/neutron/plugins/ml2/ml2_conf.ini. Tenant_network_types = VLAN Specifies that a normal user creates a network type of VLAN.Then specify the range of VLANs:The above configuration defines the range of VLAN Network,vlan IDs for which label "default" is 3001-4000. This range is for ordinary user

Answer: I can't . Because the DHCP agent is running on the control node, CIRROS-VM2 is located on the local network of the compute nodes, and the two are in different physical nodes. Because the
