@Hussein Nasser At the end of the video you had to stop and start the docker-compose in order to add a new nodeapp4, but doesn't that defeat the purpose? First issue is that you have to stop all instances (nodeapp* and the lb) instead of doing that dynamically and also adding a new nodeapp will run on the same physical machine, right?
@hnasr4 жыл бұрын
Julian Lishev thanks Julian you make valid points. Two in facts. How do you update the configuration without down time and how do you split the containers on multiple physical machines. I will have to do some research and get back to you on the first one and make a video on it. The second one is probably we need a container orchestrator like k8 or docker swarm. Good points

For example I want to config a microservice with the path localhost/microservice1/... and another microservice with the path localhost/microservice2/... Should I use an API Gateway? I have some difficulties to do this. Thanks.

Enjoyable video, thank you. I thought microservice architectur requires some sort of API Gateway to redirect requests? Is running the same app in multiple containers really considered a microservice, or is this just plain dockerizing a basic node app? Cheers
@EhSUN372 жыл бұрын
its micro services in the same server( inside docker composer instance which is running on your server). when you separate each apps and dbs etc into different machines you would need APIs to call them instead of communicating in your localhost you would communicate withing your network
@jassersaanoun94934 жыл бұрын
correct me if i'm wrong. i think this is not microservices, microservices have a proxy and a registry and a load balancer to select the service required for an incoming request (payment, users...) which are not the same, every service has it's own logic and maybe his own database, whereas this is just duplicating the same service to multiple containers that it would scale
@hnasr4 жыл бұрын
jasser saanoun thanks for your message. This is the simplest minimum basic building block of microservices. The proxies, sidecar pattern, security control plane, service discovery etc are additions to microservices architecture to make it actually manageable and maintainable and the final piece to add is kubernetes to manage all those containers.

the only difference would be how your API calls different services. you can run redis , postgres etc in the docer-composer and your apps will call them when needed. use only one app if you want and eliminate the load balancer

The Scientist none that I am aware of, if the container is assigned adequate memory/cpu it should be just as if running directly on the host. That being said it I am assuming the container daemon is running directly on the host not on a VM.
