Terraform
Resources
Hands-on: Try the Terraform: Get Started tutorials.
Resources are the most important element in the Terraform language. Each resource block describes one or more infrastructure objects, such as virtual networks, compute instances, or higher-level components such as DNS records.
- Resource Blocks documents the syntax for declaring resources. 
- Resource Behavior explains in more detail how Terraform handles resource declarations when applying a configuration. 
- The Meta-Arguments section documents special arguments that can be used with every resource type, including - depends_on,- count,- for_each,- provider, and- lifecycle.
- Provisioners documents configuring post-creation actions for a resource using the - provisionerand- connectionblocks. Since provisioners are non-declarative and potentially unpredictable, we strongly recommend that you treat them as a last resort.
