curl: (7) Failed to connect to localhost port 10001: Connection refused DOCKER

Question

I start my docker container with:

docker run -it --expose 10001 --expose 8080 -p 10001:10001 -p 8080:8080 -p 80:80 --rm lucchi/covid90/100e

My docker -ps then has:

CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS                  PORTS                                                                  NAMES

But I can't connect to localhost from inside the container. I tried:

curl 0.0.0.0:8080 
curl 127.0.0.1:8080
curl https://localhost:8080

but keep getting

curl: (7) Failed to connect to localhost port 8080: Connection refused

Most of the asnwers I read are about adding -p to the run command, I don't get what I'm missing.

Answer 1

Are you trying to connect inside the container or outside it?

Please check this SO query and answer. You may find that helpful.

From inside of a Docker container, how do I connect to the localhost of the machine?

Answer 2

Is the a server process running inside the docker on the specified port ?

If the app logs are enabled you can get the logs of the container by executing the below command.

docker logs <container_name>

Additionally for ensuring if the app is up and running fine, try doing a curl from inside of the docker container. You can use the docker exec command to execute any command inside the container.
