Hi @yunkon-kim But, we need to complete test with Spider v0.12.8 since it is our current base is https://github.com/cloud-barista/cb-tumblebug/blob/main/docker-compose.yaml#L166 Please share the testing result of this PR based on the CB-TB latest commit (Spider v0.12.8) |
|
Tests with Spider v0.12.8 passed as follows. (Note - previously, there was an issue with v0.12.8 when running on all systems where certain files/information were inaccessible. The issue was not observed in this test. I will report back next time I observe it.) |

@yunkon-kim I guess your previous failure was based on missed configuration in the upstream while updating cb-spider version from v0.12.7 to v0.12.8 (this version includes several configuration changes. also, I heard there is a mistake within cb-spider)
I think the current cb-tb latest commit would be fine. :) |

This PR improves VNet CIDR management for GCP/IBM.
This will stabilize multi-cloud resource provisioning for GCP and IBM and resolve VNet creation hangs caused by missing CSP metadata.
Tumblebug will intentionally manage the user-provided vNet CIDR block as metadata, although CSPs (e.g., GCP, IBM) do not natively support vNet (VPC) CIDR blocks.
Note - From a management perspective, this helps users (e.g., admin, network operator) easily manage network addresses and prevent errors during resource creation on different cloud platforms.
