App not launched

[suprithwork]

I tried to do the same process as specified using docker.

->did a docker pull
->docker-compose build
->docker-compose up
-> It shows that it is listening to a port 3000 via node mon in the console but my localhost:3000 doesnt work

Dont know why.
I did a docker inspect container id
docker inspect opencvexpress_cv_1

then I got all the network info but the host ip has no value but the host port has 3000 as value
How can I fix this issue

The above is the obtained data on the console for a docker inspect container id command

Hi,

Shouldn't you be connecting to the IP of your docker machine instead of localhost? Check docker-machine ls to get the IP.

[hanalice]

exec docker-compose ps command , select the port of the host machine instead of the docker machine ip. Mine is host 3001 port forward to docker container 3000 port.
