updater-terraform

Updates a Terraform variable that stores the application version.

This plugin is distributed as the standalone Go binary semrel-plugin-updater-terraform. Semrel executes the binary as a subprocess, provides plugin configuration through SEMREL_PLUGIN_* environment variables, provides release context through SEMREL_* environment variables, reads standard output, and treats exit code 0 as success and any non-zero exit code as failure. Install the binary in ~/.semrel/plugins/ or anywhere on your $PATH.
