nginx - docker stack deploy is not working properly but docker-compose is working properly -


i new docker swarm , docker compose.

i built application uses nginx , flask docker containers. nginx acts reverse proxy.

when building entire application using docker compose works fine

my docker-compose.yml file

version: '2'  services:   web:     restart:     build: ./web     image: shivanand3939/web     expose:       - "8000"     volumes:       - ./output:/usr/src/app/static     command: /usr/local/bin/gunicorn -w 2 -b :8000 --access-logfile - classifierv2restendpoint_ridge_nb:create_app()    nginx:     build: ./nginx/     image: shivanand3939/nginx     ports:       - "80:80"     volumes:       - /www/static     volumes_from:       - web     links:       - web:web    viz:     image: dockersamples/visualizer     ports:       - 8080:8080/tcp     volumes:       - /var/run/docker.sock:/var/run/docker.sock     environment:       - "constraint=node.role==manager"

below output:

however, want take next level deploying in 3 aws instances

here docker-stack.yml file

version: '3'  networks:   mybridge:  services:   web:     restart:     build: ./web     image: shivanand3939/web     expose:       - "8000"     volumes:       - ./output:/usr/src/app/static     command: /usr/local/bin/gunicorn -w 2 -b :8000 --access-logfile - classifierv2restendpoint_ridge_nb:create_app()        networks:       mybridge:         aliases:           - web     deploy:       replicas: 2       update_config:         parallelism: 2         delay: 10s       restart_policy:         condition: on-failure    nginx:     restart:     build: ./nginx/     image: shivanand3939/nginx     ports:       - "80:80"     volumes:       - /www/static     networks:       - mybridge     deploy:       replicas: 1       update_config:         parallelism: 2         delay: 10s       restart_policy:         condition: on-failure    viz:     image: dockersamples/visualizer     ports:       - 8080:8080/tcp     volumes:       - /var/run/docker.sock:/var/run/docker.sock     deploy:       placement:         constraints: [node.role == manager]

but when deploy application , check url getting

[incorrect home page]

enter image description here

i not understanding why in first case there communication between web , nginx containers in second case communication stopped.

can please guide me on this

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
