3. try to pull a image podman pull docker.io/library/httpd

Describe the results you received:

Trying to pull docker.io/library/httpd:latest...
Error: initializing source docker://httpd:latest: pinging container registry registry-1.docker.io: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: no such host

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide? (https://github.com/containers/podman/blob/main/troubleshooting.md)

Yes (version latest available CRC)

Additional environment details (AWS, VirtualBox, physical, etc.):

CRC
proxy on the same host like VM.

@baude PTAL. Is CRC using the same mechanisms podman machine does? Because I know we resolved this for machine

[Luap99]

Given that the reported version is 3.4.4 which does not have machine support on windows I would say no.

Is HTTP_PROXY set in the VM? If no then this is a crc problem. If yes then it is a problem with podman.

[mkonzal]

HTTP_PROXY was not set, but when I set it now like described in #11941, the result is the same.

[rhatdan]

HTTP_PROXY has to be set within the VM and before the podman service is started.

You can add this to containers.conf in the VM and then restart the service.

# Environment variables to be used when running the container engine (e.g., Podman, Buildah).
# For example "http_proxy=internal.proxy.company.com".
# Note these environment variables will not be used within the container.
# Set the env section under [containers] table, if you want to set environment variables for the container.
#
#env = []

[cfergeau]

Ah, interesting hint regarding containers.conf. I've come up with https://github.com/cfergeau/crc/tree/podmanproxy which I still need to try against a proxy. This uses /etc/environment.d and /etc/systemd/system/podman.service.d/ to make sure podman is run with the proxy environment variables. But imo this is more of a crc issue than of something for podman

[rhatdan]

That works also.

[rhatdan]

Since this is more about CRC and less about Podman, I am moving to Discussion.

BTW Podman machine does this automatically in its ignition file, I believe.
