error: stack names may not contain slashes

• Reason: naming naming validation
• Recommended naming convention “<orgName>/<projectName>/<stackName>“ will not work for local and cloud backend (i.e. Azure blod container)
• Error: “could not create stack: validating stack properties: a stack name may only contain alphanumeric, hyphens, underscores, or periods”
• Work around: use “<project-name>-<stack-hint>” i.e. “pulumi-demo-dev” (project-name: pulumi-demo, stack-hint: dev)
• See:

error: cannot create already existing resource

Cause:

• Pulumi resource name (unique name) is changed but the actual resource name is not changed
• Example: new ResourceGroup("UniqueXXX", new ResourceGroupArgs { ResourceGroupName = "rg-demo" });
  • UniqueXXX is changed to UniqueYYY
  • ResourceGroupName = "rg-demo" is not changed
  • Re-creation of resource group with same “rg-demo” name will fail

Solution:

• Comment out code, then pulumi up -s dev (resources will be deleted)
• Uncomment and again pulumi up -s dev
