When creating the container, you only need to specify the - network parameter as ov_ Net2.

Only need to carry out the above creation process in one node, other nodes will automatically recognize the network, because of the service discovery function of consult. See 。Ĭreating an overlay network is basically the same as creating a bridge network before, except that the – D parameter is set to overlay.

The above is the installation method for the stand-alone version of consult. You can also fill in the IP address directly. Ens3 is the network card corresponding to the IP address of the current node. Where indicates the IP of the node running the consult container. Modify the configuration file / etc / SYSTEMd / system of docker daemon of each node/ rvice 。 Add at the end of execstart In order to let the consult discover each docker host node, it is necessary to configure it on each node.

The simplest way to install the consult database is to run the consult container directly using docker.ĭocker run -d -p 8500:8500 -h consul –name consul progrium/consul -server -bootstrapĪfter startup, you can view the consult service through the 8500 port of the host IP. After that, docker will automatically store state information.

Of course, we don’t need to write code here.

Consult, etcd and zookeeper are key vlaue software supported by docker.Ĭonsult is a key value database, which can be used to store system status information. The docker overlay network needs a key value database to store network status information, including network, endpoint, IP, etc. A bridge is a bridge, a virtual switch, which is connected with sandbox through Veth. None and bridge network have been introduced before.

Libnetwork contains the above-mentioned native drivers and other third-party drivers. The implementation of network can be Linux bridge, VLAN, etc. Network contains a group of endpoints, and endpoints of the same network can communicate directly. An endpoint can only belong to one network or one sandbox. The typical implementation of endpoint is Veth pair. Each sandbox can have multiple endpoints belonging to different networks.Įndpoint is used to connect sandbox to network. In other words, Sandbox isolates one container from another through the namespace. Sandbox can contain endpoints from different networks. Linux Network namespace is the standard implementation of sandbox. Sandbox is the network stack of the container, including the container’s interface, routing table and DNS settings. This model abstracts the container network and is composed of the following three types of components: The core content of libnetwork is the container network model (CNM) defined by it. Libnetwork is the docker container network library.

Third party solutions: commonly used include flannel, weave and calico.ĭocker integrates the above solutions with docker through libnetwork and CNM. Docker cross host network solutions include:
