Deploy Kubernetes in Docker
Kubernetes is an open-source container management framework of Google. It provides a series of functions such as host, cluster management, container deployment, high availability, and auto scaling of Docker containers; kubernetes's design goals in
a single machine or moved anywhere. From a PAAs perspective, it may not be easy for an existing application to migrate seamlessly, and on the other hand, IaaS is somewhat cumbersome in some way, and the advent of Docker, aptly filling the middle, is an encouraging technique for developers and IT managers alike.The evidence suggests that Docker's current frenzy of growth is an indisputable fact:in the last 15 months More than 460 contributors have exc

Label:MongoDB is a product between relational and non-relational databases, most like relational databases in non-relational databases. Supports an object-oriented query language that can achieve almost the most functionality of a relational database single-table query, and also supports indexing of data.

Docker provides a simple command of the Operation container. But his command of the container does not belong to the system.
Because it is too simple, there must be a lot of deficiencies. For example, starting order, dependency checking, failure service recovery, and so on, all need a mature system service management software to complete.

When Docker creates a container, it uses the bridge network by default, assigning its own IP and not allowing itself to be specified.In the actual deployment, we need to specify the container IP, not allow its own IP, especially when building a cluster, fixed IP is required.We can create our own bridge network: MyNet, when you create a
