Connection refused when trying to run Kong API Gateway using a docker container

I am trying to run Kong API Gateway using a docker container. I followed the instructions on hub.docker.com/_/kong/, started Cassandra database and Kong.

I have Cassandra running using the below command:

docker run -d --name kong-database \
       -p 9042:9042 \
       cassandra:3

and Kong running using the below command:

docker run -d --name kong \
      --link kong-database:kong-database \
      -e "KONG_DATABASE=cassandra" \
      -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \
      -p 8000:8000 \
      -p 8443:8443 \
      -p 8001:8001 \
      -p 7946:7946 \
      -p 7946:7946/udp \
      kong:latest

Both containers are running. (I don’t have enough reputations to embed pictures here right now so please see a screenshot here: my container list)

However when I do:

$ curl http://127.0.0.1:8001 

I got this:

curl: (7) Failed to connect to 127.0.0.1 port 8001: Connection refused

Can anyone let me know what is the possible reason?
