According to the CNI spec, our
host-local
ipam module will always put the gateway at.1
inside our subnet. If the derived address from the config fails to connect, fallback and try the internal CNI gateway. Should improve compatibility when the container does not have an IP, such as rootless configurations.Fixes #1573.
