getting this error while curl the application ip

curl (56) Recv failure: Connection reset by peer - when hitting docker container

Solution

Do a small check by running:

docker run --network host -d <image>

if curl works well with this setting, please make sure that:

1. You're mapping the host port to the container's port correctly:

docker run -p host_port:container_port <image>

2. Your service application (running in the container) is running on localhost or 0.0.0.0 and not something like 127.0.0.1
