docker inspect --format doesn't work in Windows

[zkanda]

Hello I'm trying to use docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' from docker inspect examples. But it's giving me these error:
Template parsing error: template: :1: unexpected unclosed action in range

I'm using the docker quickstart terminal.

I created it here because that same command works in Linux machines.

Wondering; does it work if you use double quotes? " instead of '?

[zkanda]

Doesn't work with double quotes as well.

[thaJeztah]

alright - can you open an issue in the https://github.com/docker/docker/issues issue-tracker? This sounds like an issue in the Docker Engine (or a combination of Docker Engine and the environment the CLI runs in)

[calavera]

it could be an issue in how Go parses the format in Windows. The engine doesn't do anything different to parse the format whether it's linux or windows.

@thaJeztah Same problem but when I change ' to " it work . Thanks
docker inspect --format "{{ .NetworkSettings.IPAddress }}" zookeeper

[Good old necro posting]

Thank you @Gmanweb . The following command does indeed do the job still in 2020:

docker inspect --format "{{ .NetworkSettings.IPAddress }}" <container_name>

Still, there doesn't seem to be a way to ping a Linux Docker containing from a host Windows machine. Anyone found a way to do that?

[thaJeztah]

The container's IP address is an internal IP address; to ping/reach the container, use port mapping to publish its port(s);-p <host-port>:<container-port> (e.g. -p 8080:80 to map container port 80 to port 8080 on the docker hosts network interface. Then connect to the container at <host ip address>:8080.

Already tried this solution, but it didn't work. I'm running a Flask app within my Docker container at port 5000 and I would like to expose it at that same port, so that it would be reachable from my local Windows 10 machine.

The thing is that I can't even ping my container's IP address in the first place.

If it's a linux container, the container runs inside a lightweight VM, and that IP address isn't accessible from your host.
Make sure the app inside the container is listening on 0.0.0.0, and (assuming you're using Docker Desktop) when publishing the port (-p 5000:5000), is should be accessible on localhost:5000 from your Windows machine

Finally got it working with this hint, thank you so much!!

In the Dockerfile, I specified the following command to start the flask app:

ENTRYPOINT ["flask", "run", "--host=0.0.0.0"]

And then, I ran the container with the following command:

docker run -p 5000:5000 <image_name>

Finally, I was able to access my webapp in the browser!

On Windows 10
docker image inspect --format='{{index .Config.Labels \"maintainer\"}}' <image_name>

As suggested above, it worked after replacing single quotes with double quotes:

docker inspect --format="{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}"
