Issues building Kolla images with recent versions of Python requests
If you find yourself having issues building Kolla docker container images with errors like this: INFO:kolla.common.utils:Using engine: docker INFO:kolla.common.utils:Found the container image folder at /home/mikal/src/kerbside-patches/venv-stable/2023.1-patches/share/kolla/docker ERROR:kolla.common.utils:Unable to connect to container engine daemon, exiting INFO:kolla.common.utils:Exception caught: Error while fetching server API version: Not supported URL scheme http+docker It is likely that you're running a recent version of requests which has an unresolved issue. Try downgrading requests manually, like this: $ ...venvpath.../bin/pip install requests==2.31.0 Collecting requests==2.31.0 Downloading requests-2.31.0-py3-none-any.whl (62 kB) ...snip... Successfully installed requests-2.31.0 Thanks for this stack overflow post for the pointer.
