In host command windows:
docker run -d --name cors-proxy cors-proxyBrowse link "localhost" or "localhost:8080", it will show:
Docker Running ! Hello World from static HTML
Browse link "localhost/hello" or "localhost:8080/hello", it will show:
Hello World from Flask
It can open another host comand windows and run the below command to check log:
docker logs -f corsIn addition, it can run the bash of container to do what you want, like install additional packages, etc.
docker exec -i -t cors-proxy /bin/bashroot@c19867aff7dc:/app# ls
__pycache__ main.py static uwsgi.ini
root@c19867aff7dc:/app#docker run -d --name cors-proxy cors-proxy
or
# redirect aceess from localhost:8080 to container:80
docker run -d --name cors-proxy -p 8080:80 cors-proxy
docker start cors
docker restart cors
docker stop cors# exec bash in container
sudo docker exec -i -t cors-proxy /bin/bash
# show Nginx logs
docker logs -f cors# docker cp <containerId>:/file/path/within/container /host/path/target
docker cp nginxpx:/etc/nginx/nginx.conf .docker rm -f cors
# remove all containers
docker rm -f $(docker ps -aq) docker rmi
