docker-compose

问题 I have a sample compute service in my docker-compose file which works just great as expected. version: "3" services: compute-service: image: dummy/compute environment: - INPUT=2 However there could be times in which I need to run this service with diff inputs (say INPUT = 4, 7, 9, 10, 12..etc). I do not like the idea of copying and pasting the service multiple times for each input. Scaling is an option. But how can I ensure that each instance works on unique input variable. I am aware that I

问题 this is just a question about theory, my app is running perfectly... So, I have 3 services runing with docker-compose: a postgres database , a backend springboot and a frontend angular . From what I know, docker containers can acess ports from other docker containers without the need to expose the port, so there is no need to expose nor bind the ports because they are all containers and can access each other with the default bridge network mode (that's what I learned, don't know if this is

问题 I have experience using Docker to develop a relatively complex application. It is very easy to debug an app using Visual Studio (2019). I just set docker-compose.yaml as the startup app and start debugging. Is it possible to debug an application that is published to Kubernetes locally using Docker Desktop? By debug I mean set breakpoints etc? I have spent a few hours Googling this and I have got nowhere and hence the reason for the question. Please note that I am not asking how to debug an

问题 If I have a great many services defined in a docker-compose project, how can I exclude a service from the default docker-compose up command? For example, I have an nginx service, and an ssl service. They conflict because they both consume port 80, so how can I make it so that the ssl service doesn't start unless I specifically run that service, and by default the up command will do everything EXCEPT the ssl service? 回答1: Not exactly what you're looking for but you could use the scale flag to
