无法从Apache-Superset容器（tar文件）映像启动容器（无法连接到本地主机端口）

Question

I'm quite new to Docker and Apache-Superset and trying to run a container (using docker) from the container image. Loaded the .tar file with

docker load --input ./inc_superset.tar

Which went as expected, tried running the container from this image file with

docker run --cidfile ./cid.txt <IMAGE_ID>

This starts my container but is has unhealthy status; upon inspecting the container ( with docker inspect) I get a huge JSON, below is a snippet of the log received (can post the entire log on request).

"Health": {
  "Status": "unhealthy",
  "FailingStreak": 5,
  "Log": [
    {
      "Start": "2019-01-22T19:59:00.8036984+05:30",
      "End": "2019-01-22T19:59:01.5698797+05:30",
      "ExitCode": 7,
      "Output": " % Total % Received % Xferd Average Speed Time Time Time Current\n Dload Upload Total Spent Left Speed\n\r 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl: (7) Failed to connect to localhost port 8088: Connection refused\n"
    },
    ...
    ...
    {
      "Start": "2019-01-22T20:01:02.589517677+05:30",
      "End": "2019-01-22T20:01:02.794486003+05:30",
      "ExitCode": 7,
      "Output": " % Total % Received % Xferd Average Speed Time Time Time Current\n Dload Upload Total Spent Left Speed\n\r 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl: (7) Failed to connect to localhost port 8088: Connection refused\n"
    }
  ]
}

Am I making any mistake? Am I missing something? Any troubleshooting help on this requested.

Thanks

The problem was the webserver within the superset container doesn't run by default as of the configuration available on apache.org as of 7 September 2019.

Solved it as follows:

#Go into the container
docker-compose exec superset bash
#Start the webserver that is exposed on all interfaces so that we can access it from docker host
superset run -p 8088 --host 0.0.0.0

I was facing the same issue. Ran via docker-compose using the instructions on https://superset.incubator.apache.org/installation.html but get no response from localhost:8088.

Docker inspect State.Health.Status = "unhealthy" and log show several entries with curl: (7) Failed to connect to localhost port 8088: Connection refused\\n"

docker ps shows that the container is exposed on 0.0.0.0:8088
