Abstract
The present invention provides a kind of Docker network plug-ins implementation method, belong to computer software application field, when business scenario needs to configure host network IP for Docker containers, when container is created, can be by specifying network plug-in title, call the network plug-in, now the network plug-in can create a pair of link in host network interface card, for connecting host network and capacitor network, the link that capacitor network is represented adds the NameSpace that container is provided, it is simultaneously the link configuration of IP and gateway, so that the IP of container and host IP are in the same network segment.
Description
Technical field
The present invention relates to computer software application technology, more particularly to a kind of Docker network plug-ins implementation method.
Background technology
Docker is an application container engine increased income, allow developer can pack they application and rely on bag arrive
In one transplantable container, then it is published on the Linux machines of any prevalence, it is also possible to realize virtualization.Docker mesh
Before there is multiple network pattern, comprising Bridge patterns, Host patterns, OverLay patterns, but these network modes but work as
We want to allow Docker containers with host network in same address field, also without this Plugin Mechanism.Early stage is when our industry
When business system needs this network mode, it is common practice that increase service code in operation layer and complete, now in the presence of many defects,
For example when we use the ecological others open source projects of Docker（Compose）When carrying out container layout, it is impossible to call operation layer
The IP management logics of realization.
Etcd is a key/value storage service applied under distributed environment, can in the cluster share letter
Breath, reads writing speed quickly.When we under cluster environment, it is necessary to during using the network plug-in, it is possible to use Etcd is used for
The storage network information, the network plug-in of different nodes can share the network information of Etcd storages.
Docker is ecological to provide ripe network plug-in mechanism, and user can be based on the ecological networks for providing of Docker
API, the self-defined business network of oneself completes the distribution and recovery of Docker capacitor networks.
The content of the invention
The present invention proposes a kind of Docker network plug-ins implementation method.Solve in production environment with Docker network egress
The form of part completes the IP management of container such that it is able to preferably carried using the Container Management and Docker ecologies of Docker
The sundry item of confession.
The technical scheme is that：
When business scenario needs to configure host network IP for Docker containers, first when container is created, can be by referring to
Determine network plug-in title, call the network plug-in, now the network plug-in can create a pair of link in host network interface card, for even
Host network and capacitor network are connect, the link that capacitor network is represented adds the NameSpace that container is provided, while to be somebody's turn to do
Link configuration of IP and gateway, so that the IP of container and host IP are in the same network segment, and are maintained in the life cycle of container
Keep constant.
Comprise the following steps that：
A：Host creates br0 bridges, and will change bridge and be tied to eth0, installs the Docker of 1.12 versions
B：Host operational network plug-in unit, network is created using docker orders, and it is locak to specify network driver, and is specified
Network Details：
docker network create --driver=local --gateway=192.168.159.2 --subnet=
192.168.159.0/24 local
C：Container is created based on docker orders
docker run -itd --ip=192.168.159.140 --net=local 10.110.17.138:5000/
centos:6.7
D：Container is created successfully, logs in container, can view container IP information.
This method is realized based on golang language, when needs are made when cluster environment is using the plug-in unit, it is necessary to install Etcd
It is shared storage, for storing the network information, while needing to start plug-in unit in each host.
When network is created, first check for whether the network has created completion, if not creating, network trust system is arrived
Etcd databases.
The beneficial effects of the invention are as follows
The Docker ecosystems provide a kind of network plug-in mechanism, it is allowed to the network insertion that user oneself will define to Docker
The ecosystem, network plug-in mechanism of the present invention based on Docker, Docker containers are realized with reference to Linux iptables technologies
IP distribution and configure, when the IP address of Docker containers is needed with the network of host, it is possible to use the plug-in unit complete from
Dynamicization is configured, and reduces a large number of services layer logic, and can be consistent with Docker ecologies.
Brief description of the drawings
Fig. 1 is cluster mode lower network plug-in unit deployment schematic diagram；
Fig. 2 is capacitor network and Link to schematic diagram.
Specific embodiment
More detailed elaboration is carried out to present disclosure below：
1) this method environment is based on Ubuntu14.04 operating systems, and host needs to create network br0, and is tied to eth0,
Host disposes the Docker of 1.12 versions, and the listening port of Docker is br0, as follows：DOCKER_OPTS="$
DOCKER_OPTS -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --cluster-
store=etcd://127.0.0.1:4001 --cluster-advertise=br0:2376"
2) this method based on golang language realize, when need when cluster environment is using the plug-in unit, it is necessary to install Etcd as
Shared storage, for storing the network information, while need to start plug-in unit in each host, as shown in Figure 1.
3) this method first checks for whether the network has created completion, if not creating, by network when network is created
Information is saved in Etcd databases.
4）When creating container based on this method, network plug-in can obtain the IP that can be used from Etcd databases, and to hold
Device creates a pair of link, and configuration of IP, as shown in Figure 2.
Claims (4)
1. a kind of Docker network plug-ins implementation method, it is characterised in that
When business scenario needs to configure host network IP for Docker containers, first when container is created by specifying network egress
Part title, calls the network plug-in, and now the network plug-in can create a pair of link in host network interface card, for connecting host
Network and capacitor network, the link that capacitor network is represented add the NameSpace that container is provided, while being the link configuration of IP
And gateway, so that the IP of container and host IP are in the same network segment, and it is constant to be maintained at holding in the life cycle of container.
2. method according to claim 1, it is characterised in that
