Docker: curl: (7) Failed to connect to localhost port 9089: Connection refused

Question

I am trying to connect to my IAM server by using:

curl -i -X POST -H "Content-type: application/json" http://localhost:9089/account/list -d '{"jwt": "jwt_token..."}'

and in doing so I get an error as follows:

curl: (7) Failed to connect to localhost port 9089: Connection refused

Any suggestions would be greatly appreciated!

Edit:

Answer 1

Try below

curl -i -X POST -H "Content-type: application/json" http://localhost: 32768/account/list -d '{"jwt": "jwt_token..."}'

Your docker ps shows

root@Ubuntu1604-001:/home/src/IAM# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                     NAMES
cc28d00d1667        blandry             "npm start"         33 minutes ago      Up 33 minutes       0.0.0.0:32768->9089/tcp   objective_mclean

That means you didn't map 9089 to 9089 . To do that make sure you run your container as

docker run -p 9089:9089 <image>

Answer 2

If you are trying to do this curl inside a docker you don't need the http prefix. I had this same issue yesterday, and I succeeded when I tried sending curl name_of_container:port/path/to/the/method .

Answer 3

You have mapped 32768 host port with 9089 port of docker.

root@Ubuntu1604-001:/home/src/IAM# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                     NAMES
cc28d00d1667        blandry             "npm start"         33 minutes ago      Up 33 minutes       0.0.0.0:32768->9089/tcp   objective_mclean

Use 32768 port instead of 9089 port.

curl -i -X POST -H "Content-type: application/json" http://localhost:32768/account/list -d '{"jwt": "jwt_token..."}'
