Hyperledger Fabric 部署的多种方式

由于 Hyperledger Fabric 组件被部署为容器，因此在本地主机中运行时一切正常。当它们运行在不同的主机上时，我们需要找到一种方法让这些容器相互通信。

静态IP 通过指定运行容器的主机IP，容器之间可以相互通信。这些主机 IP 是使用 docker-compose 文件中的 extra_hosts 指定的，并且在容器运行后，可以在 etc/hosts 中看到这些条目。缺点是事物是静态配置的，当需要添加或更改配置时会遇到挑战。

Docker Swarm Docker Swarm 是 Docker 环境中原生的容器编排工具。简而言之，它为跨多个主机的容器提供了一个覆盖网络。这个覆盖网络上的那些容器可以相互通信，就像它们在一台大型主机上一样。显然，好的一面是可以使用原始配置，只需很少的修改，并且配置中没有编码IP等静态信息。

Kubernetes (k8s) K8s 是迄今为止最流行的容器编排工具。该机制类似于 Docker Swarm。这种方法的实现比前两种机制更具挑战性，但这种方法更具可扩展性，并且是 Hyperledger Fabric 团队推荐的。

Hyperledger Fabric on Kubernetes

Description
In this course, you will learn to design and deploy Hyperledger Fabric applications on Kubernetes. This course is specifically designed for those seeking to learn hyperledger fabric deployment on Kubernetes. By the end of the course, you will be able to design, develop and deploy your hyperledger fabric network on any cloud, since we have used the cloud-agnostic approach. This course is completely hands-on and we will be focusing more on the practical approach rather than the theoretical.

Various Ways for Hyperledger Fabric Deployment

As Hyperledger Fabric components are deployed as containers, everything works fine when running in the localhost. When they are running in different hosts, we need to find a way to make these containers talk to one another.

Static IP By specifying the host IP where a container is running, containers can communicate with each other. Those host IPs are specified using extra_hosts in docker-compose files, and after a container is running, these entries are seen in, etc/hosts. The downside is that things are statically configured, and there are challenges when one needs to add or change the configuration.

Docker Swarm Docker Swarm is a container orchestration tool natively in the Docker environment. In a nutshell, It provides an overlay network for containers across multiple hosts. Those containers on this overlay network can communicate to one another as if they were on a large host. Obviously, the good side is that the original configuration can be used with minimal modification, and no static information such as IP is coded in the configuration.

Kubernetes (k8s) K8s by far is the most popular container orchestration tool. The mechanism is similar to Docker Swarm. The implementation of this approach is much more challenging than the previous two mechanisms but this approach is much more scalable and recommended by the Hyperledger Fabric team.
