Exploring Podman: A More Secure Docker Alternative

Re:Exploring Podman: A More Secure Docker Alternative by koito17 on Saturday January 13, 2024 @02:12PM (#38983441)

I use Podman on Mac OS. I've found the experience better than Docker for the most part, especially when it comes to supporting older versions of Mac OS. The only major downside of Podman on Mac OS is that you cant use the host network in a container, but people will rarely want to use the host network in a container anyway. This is something to keep in mind if you want to experiment with network things in a container and want to retain the same hostname and IP address of your host, however. I manage to work around this limitation anyway.

And this isn't even a Podman-specific issue, it's true of Docker Desktop as well [0]:

I'm a podman beginner, trying to install ollama-webui(1) using Podman on M2 MBA.

I started up Podman Desktop, and did a terminal command "docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v ollama-webui:/app/backend/data --name ollama-webui --restart always ghcr.io/ollama-webui/ollama-webui:main" based on Github's instructions, but it gave a error message something about "host".

the exact error message was ""Error": "failed to create new hosts file: unable to replace \"host-gateway\" of host entry \"host.docker.internal:host-gateway\": host containers internal IP address is empty""

Do you know what is the problem and how do I overcome this?

If I run the above command using Docker Desktop, it runs and installs Ollama-WebUI just fine.

Thank you.
