tfmv

Simple tool for moving / renaming resources in one or several terraform configurations.

When moving or renaming resources or modules in terraform configurations, objects in the corresponding state are typically destroyed and recreated by terraform apply.

This may be impractical, or impossible for certain resources, and the objects in the state must be moved manually, one by one, to prevent this.

This tool helps to automate this state operation.

The operations are:

• terraform state pull to get local copies of the remote state(s)
• terraform state list to identify objects matching the given prefix
• terraform state mv is called to move or rename the resource based on the prefix
• terraform state push to push the modified state back to the remote
• clean local files

Usage:

• rename:

  tfmv google_compute_network.old_name google_compute_network.new_name --src /home/vincent/my-project 
  

• move from root to module:

  tfmv google_compute_network.vpc module.my_module.google_compute_network.vpc --src /home/vincent/my-project  
  

• renaming module:

  tfmv module.my_module module.my_module_renamed --src /home/vincent/my-project
