My API couldn't be published on the specific ip address (VM host) when using docker

First, I run the file in terminal : Rscript run.R

This works fine, my api is up and running on the ip address http://35.157.131.3:8000/swagger/ . After which, I would like to deploy it with docker:

docker run --rm -p 8000:8000 --expose 8000 -d --name diemdiem trestletech/plumber

This showed the file was plumbed successfully, however, when i went to the api link, http://35.157.131.3:8000/swagger/ showed 404-error.

After reading docker documentations, i created a container network which specifies the host ip address that i want the docker container would run on:

-o "com.docker.network.bridge.host_binding_ipv4"="35.157.131.3" \
simple-network````

then, i connect the running diemdiem container to simple-network:

``` docker network connect simple-network diemdiem```
I inspect to see whether the container is connected or not:
```docker network inspect simple-network```
The result is: 

[
    {
        "Name": "simple-network",
        "Id": "95ec0c55aeb984952459edda2d4d0bb7c9eea71824e6cec184b7c61d2e807e7b",

        "Options": {

        },
        "Labels": {}
    }
]

The final API is still not up and running in the ip address which i specified. I appreciate your advice.

  • If you're getting an HTTP 404 error, your browser or other HTTP client is successfully connecting to _something_; the Docker networking settings you're trying to change probably aren't the problem. The `-p` option you show in your original command should be all you need (you do not need `--expose` even). – David Maze Jul 08 '19 at 18:34
  • yep, it connects to something but if it works successfully, the URL http://35.157.131.3:8000/swagger/ should be up and running like when i deployed in the terminal without docker :( – Diem Nguyen Jul 08 '19 at 18:46
