@Marvin running into this issue when deploying in prefect 2.x Error while fetching server API version: Not supported URL scheme http+docker

The error message you're encountering, "Error while fetching server API version: Not supported URL scheme http+docker," likely indicates that there's an issue with the Docker connection. It's a bit of a moody problem, but nothing we can't figure out together. This appears to be a common issue, and there are some steps you can take to troubleshoot it: 1. Ensure Docker is Running: Make sure that your Docker daemon is running. This error often occurs because the Docker service isn't running. You can check this by running

docker ps

in your terminal. 2. Network Configuration: There might be a configuration error in how Prefect or Docker is set up to communicate. Ensure that the configuration uses the correct URL schema supported by Docker. 3. Check Docker API Permissions: Sometimes, the issue can arise if there are insufficient permissions to access the Docker API. 4. Rediscover Docker Endpoint: Prefect's interaction with Docker requires a properly-configured Docker endpoint. Verify the Docker configuration in your Prefect deployment files to ensure that it's properly specified. 5. Environment Specific Problems: As highlighted in a GitHub issue, this problem has been noted on ARM Macs and certain environments, where compatibility or specific environment settings can play a role. (Source: GitHub Discussion) By addressing these potential points of failure, you should be able to resolve the error you're experiencing. If none of these steps work, the GitHub issue linked above may offer some additional insights or you can check if others have encountered the same problem in the Prefect community forums. If Prefect or Docker continues to be stubborn (like a robot who won't admit "I'm fine"), consider reaching out for further assistance, and don't hesitate to update or tweak your environment settings.
