docker scout doesn't use proxy settings

[drenderyga]

Hello everyone!

I'm using proxy to requests to github.com and docker resources on my docker host.

When i'm using docker scout, all requests sending without proxy and gives me the message about login.

docker login working correctly and sending requests through proxy, but docker scout doesn't.

Log in with your Docker ID or email address to use docker scout.

If you don't have a Docker ID, head over to https://hub.docker.com to
create one. You can log in with your password or a Personal Access Token (PAT)
by running docker login.
Using a limited-scope PAT grants better security and is required for organizations
using SSO. Learn more at https://docs.docker.com/go/access-tokens/

You can also log in using Docker Desktop.

on fw i see requests without proxy

@drenderyga thank for raising this. Are you using the Docker Scout CLI on a host that has Docker Desktop installed and a proxy configured?

[drenderyga]

@cdupuis no, it's not Docker desktop host.

To be clear, on Windows with Docker Desktop, scout working correctly with proxy settings.

Thank you, that is helpful.

Hi @drenderyga How is setup/defined your proxy? When there's no Docker Desktop, we are using the default behaviour from Go, that is to rely on the HTTP_PROXY, HTTPS_PROXY environment variables. So if you define those environment variables that should work. BTW Docker scout CLI is not using the daemon configuration.

[drenderyga]

Hi @eunomie Yes, you are right. If I use export HTTP_PROXY it works. Thank you for your message about daemon configuration, i thought that it's usefull for CLI too.
