This will not modify your infrastructure, but it can modify your state file to update metadata. This metadata might cause new changes to occur when you generate a plan or call apply next. Options: -backup=path Path to backup the existing state file before modifying. Defaults to the "-state-out" path with ".backup" extension. Set to "-" to disable backup. -input=true Ask for input for variables if not directly set. -no-color If specified, output won't contain any color. -state=path Path to read and save state (unless state-out is specified). Defaults to "terraform.tfstate". -state-out=path Path to write updated state file. By default, the "-state" path will be used. -target=resource Resource to target. Operation will be limited to this resource and its dependencies. This flag can be used multiple times. -var 'foo=bar' Set a variable in the Terraform configuration. This flag can be set multiple times. -var-file=foo Set variables in the Terraform configuration from a file. If "terraform.tfvars" is present, it will be automatically loaded if this flag is not specified. ` return strings.TrimSpace(helpText) } func (c *RefreshCommand) Synopsis() string { return "Update local state file against real resources" }
