How to organize orchestration between microservices in Docker?

Question

Java

Hello, dear forum users. I have a problem, but I don't know how to solve it. Essence: Several microservices in docker containers, one of which is spring boot. The goal is to transfer data from container to container. For example: Filling out a form in the web-UI. Further transfer to the springboot in the controller. Next, the controller sends the parser to the service. Next, the parser service sends to the mapper service. Next, the mapper sends to the database. I tried to poke in Kafka and JMS, but I don’t understand many things, please help me figure out the network interaction between containers. Question: What are the prerequisites to ensure this interaction of containers inside Docker

Answer 1

1) the architecture is so-so...
2) each service must know where to knock - look at consul.io or zookeper
3) have not mastered Kafka, start with something easier, for example, apache pulsar
4) Well, yes, orchestration is the same in docker, as well as without it. But docker-composer is also possible
5) alas, microservices are often more complicated than they seem.
