Docker manually configure the container network The network of the Docker container is a combination of the net namespace and the virtual device, which creates a pair of virtual interfaces Veth pair at startup, which are placed in the local and container respectively, The local Veth is assigned a name similar to the v

Docker Network Working principle When the Docker server is Docker daemon starts, it automatically creates a bridge with a name of Docker0, and whenever Docker creates a container, it creates a veth* port on the host named Etherne

IntroductionA Web service is necessary to run the two major functional modules: Business processing, data services, large Web services require more components, which often require multiple containers, but we also need to be able to network communication between these containers, mutual cooperation.Dokcer currently only supports host-to-container communication, and container-to-container communication.Port m

' modify success! ' | | Echo ' Modify fail! 'DoneFiThis script is used, the speed limit can be directly targeted to download and upload, and the restrictions are unified effective, such as I limit a container bandwidth of 5m, then download and upload the speed limit is 5m, the unit is bit is not byte. Three, the following is the use of the method: [Root@docker-test3 tmp]# SH modify_docker_container_network_limit.shUsage:operation container_name Lim

In the previous section we prepared the Macvlan experimental environment, and today we create Macvlan network Mac_net1 in Host1 and host2:650) this.width=650; "Title=" http://7xo6kd.com1.z0.glb.clouddn.com/ Upload-ueditor-image-20170815-1502768401876055089.png "src=" http://7xo6kd.com1.z0.glb.clouddn.com/ Upload-ueditor-image-20170815-1502768498693056007.jpg "style=" border:0px;float:none; "/>Note: The same command will be executed in Host2 . -d macvl

If you ever need to write a low-level network application, it could be necessary to handle the low-level data transmission O Ver The wire between the machines. This operation requires some sort of conversion of data from the native host operating system to the network format and VI Ce versa. This was because each of the one hat its own specific representation of

Winpcap network programming 10-Winpcap practice, two hosts communicate through the intermediate host, winpcap Network Programming Note: I will not make this blog completely public if I reach out to the party, the source code, and so on. This article provides some ideas for network programming or curriculum design .. Ok

In the previous section we created two Macvlan and deployed the container with the following network structure:This section verifies the connectivity between Macvlan.Bbox1 can ping through Bbox3,bbox2 can ping bbox4. That is, the same Macvlan network can communicate.Bbox1 cannot ping Bbox2 and bbox4. That is, there is no communication between different macvlan networks. But it should be more accurate to say

The topology diagram is as follows: host1:10.20.10.70 host2:10.20.10.71 Create a OvS switch on Host 1 and Host 2, respectively: Ovs-vsctl add-br OVS0IP Link set ovs0 up Add a port (br0 on the same network segment) for OVS0, respectively: Ovs-vsctl Add-port Ovs0 Br0 Create a GRE tunnel to Host2 in Host 1: Ovs-vsctl add

The last one said to install the Docker and Docker-compose, now start downloading the source code and joining the channel Download and install the Curl tool 1, create Fabric Engineering and project directory.

In the previous section we prepared the Macvlan experimental environment, and today we create Macvlan network Mac_net1 in Host1 and host2: Note: also execute the same command in Host2. ①NBSP; -d Macvlan NBSP; specifies driver as Macvlan. ②macvlan Network is the local network, in order to ensure that cross-host co

A few words to master subnet mask, IP address, host number, network number, network address, broadcast address1, 191.172.16.10.33/27 in the/27 that is, the subnet mask is 255.255.255.224 that is 27 full 12. From the subnet mask 255.255.255.252 to obtain its network bit is 30 bits, so only the remaining 2-bit master, th

Get host address information In Java we use the InetAddress class to represent the destination network address, including the host name and numeric type address information, and the InetAddress instance is immutable, and each instance always points to an address. The InetAddress class contains two subclasses, corresponding to the two version of the IP address:

To make it easier for machines and Docker containers in the local network to communicate, we often have the need to configure the Docker container to the same network segment as the host. This requirement is actually very easy to achieve, we simply will

network communication often involves byte-order conversion, then understand the host sequence and network order what similarities and differences.① host byte order HBO (host byte order)Use small-endian (Little-endian), low-to-high sequential storage.The low byte is emitted a

Docker by default is the Linux with the Network Bridge implementation, in fact, the Openvswitch project as a mature virtual switch implementation, with a richer function. Personally, the future Docker will necessarily support Openvswitch as its default network bridge implementation. Interested students welcome the foll
