Windows: Problem with creating singularity image

[KrzysZG37]

Using the following command:
docker run quay.io/singularity/docker2singularity -f <<container_name>>
I received the following output:
docker: error during connect: Post http://docker:2375/v1.39/containers/create: dial tcp: lookup docker on 192.168.65.1:53: no such host.

What is the -f argument for? Have you tried running the same command for a different container (e.g., something like a base image?)

[vsoch]

Also, with docker2singularity you are going to need to follow the instructions in the README and bind all the necessary bits on your host. It won't work to just run.

[vsoch]

Based on this issue docker/for-mac#1827 and the output above, you are trying to interact with a private registry (using only http), one called docker on port 2375. It also looks like it's an address in France. https://whatismyipaddress.com/ip/92.168.65.1 I think maybe you have a configuration for a local or different registry?

[vsoch]

Just tested locally, interaction with Quay.io works okay from here:

$ docker pull quay.io/singularity/docker2singularity
Using default tag: latest
latest: Pulling from singularity/docker2singularity
[DEPRECATION NOTICE] registry v2 schema1 support will be removed in an upcoming release. Please contact admins of the quay.io registry NOW to avoid future disruption.

@vsoch

1. -f argument refers to building image into sandbox directory
2. I tried it on multiple containers, not only custom ones created by me, but also ubuntu, etc.
3. I've succefully pulled this image using docker pull quay.io/singularity/docker2singularity, so this works fine

One remarks: i am using windows, but i have tested it on ubuntu as well

[vsoch]

The error I'm seeing is referencing another registry, something hosted in France. It does not look related to docker2singularity. If you want to run on your ubuntu, show me the exact command you use (with binds) then I can offer to help. Otherwise, I can't help with Windows, but I'd suggest googling that error.

[KrzysZG37]

Right now, i need to run it on windows. Probably the problem could be caused by docker.sock mount as it could be seen on the example in Readme.md file:

docker run -v /var/run/docker.sock:/var/run/docker.sock \
-v /host/path/change/me:/output \
--privileged -t --rm \
quay.io/singularity/docker2singularity \
-w \
ubuntu:14.04

but i don't know what should i put as docker.sock reference

[vsoch]

I'm sorry I can't help you - I haven't used Windows in 10 years, definitely not for containers. I'd suggest you find someone that does, or try various suggestions in posts like this one https://stackoverflow.com/questions/36765138/bind-to-docker-socket-on-windows

[KrzysZG37]

Okay, i lead to working solution on linux, but windows probably has problem with supporting it.
