Hey I'm new to kubernetes trying to implement the kubernete federation and was able to configure the aws and GCP credentials and got a successful output while testing for AWS but when I was trying to use it for GCP got stuck with an error
command: juju bootstrap google mycloud
ERROR fetching hosted model spaces: adding subnet "10.142.0.0/20": subnet "10.142.0.0/20" already exists
ERROR failed to bootstrap model: subprocess encountered error code 1
Looks like subnet "10.142.0.0/20" already exists in GCP (Google Cloud Platform) you can find all your networks and subnets in the GCP by running a command in the Google Cloud Shell
gcloud compute networks subnets list
or find it in Networking > VPC network > VPC networks section of the GUI
It looks like you use default GCP subnet
us-east1 default 10.142.0.0/20 10.142.0.1
you can delete all default subnets from GCP, or try to configure networking in your config file
~/.juju/environments.yaml
