The second link: Dockercon HackathonJune 7 8th, we Chinese developers in Beijing held a golangdocker hackathon,dockercon Eve, San Francisco also held a Docker Hackathon. This time the hackathon was born with a lot of new ideas, and the Geek spirit of whale powder was vividly played. Because the content is too rich, I'll just introduce two projects th

sounds like DNS, it really is. The difference is that this service discovery is used within your cluster to help service find each other. However, DNS is usually more static and is helping outside to request your service. At the same time, DNS servers and DNS protocols are not suitable for controlling the changing environment of microservices, and containers and nodes are often increased and decreased.Most of the service framework provides one or more choices to service discovery. By default, S

This is a creation in Article, where the information may have evolved or changed. Part VI: Go microservices-Health Check As our microservices become more and more complex, it is important to have a mechanism that lets Docker swarm know that a service is healthy. Therefore, this article focuses on how to add a health check for a microservices service. If the Accountservice micro-service does not have the following capabilities, it is useless: pro
