How to run two processes in a Docker container. In this example, I run a GoLang REST Server and SpringBoot REST Client in single Docker container.
As per this document, it appears that it’s an anti-pattern to run multiple services in one Docker container. But after re-reading the document, my understanding is that we should have one service per container. This services can spawn multiple processes like Apache web server starts multiple worker processes. So I think it’s ok to have multiple processes in a Docker container in case our use case really really needs it.
E.g. This kind of architecutre may be good for running a batch application that depends on a REST API and cannot afford to make REST calls over the network.
