Short, punchy solutions to real-world cloud engineering problems. Optimized for 3 AM debugging.
Azure DevOps pipeline fails with 'Failed to connect to the host via ssh' when running baseline against Ansible host.
Comment out the FQDN override for ansible_host in your inventory/compose file; it breaks DNS resolution.
App Service returns 403 Forbidden even when accessed via Private Endpoint from the same VNET.
Ensure 'Access Restrictions' in the Networking blade allows traffic from the specific VNET subnet or disable 'Allow Public Access'.
Pod stuck in ImagePullBackOff when pulling from a private ACR/Registry.
Create and link an imagePullSecret to the Deployment or ServiceAccount.
Terraform plan/apply fails because the state is locked by another process (or a crashed CI run).
Verify no active runs exist, then use `terraform force-unlock <LOCK_ID>`.

Spoke VNets unable to resolve records in a Private DNS Zone linked only to the Hub VNet.
Ensure the Private DNS Zone is linked to all Spoke VNets, or implement a centralized DNS resolver in the Hub.
