You can use this option multiple times to include more than one object. Limit the planning operation to only the given module, resource, or resource instance and all of its dependencies. Select the "refresh only" planning mode, which checks whether remote objects still match the outcome of the most recent Terraform apply but does not propose any actions to undo any changes made outside of Terraform. Select the "destroy" planning mode, which creates a plan to destroy all objects currently managed by this Terraform configuration instead of the usual behavior. Use this option more than once to include more than one variable file. Load variable values from the given file, in addition to the default files terraform.tfvars and *.auto.tfvars. Use this option more than once to set more than one variable. ![]() Set a value for one of the input variables in the root module of the configuration. This can be used as input to the "apply" command.Īsk for input for variables if not directly set. This command will not actually perform the planned actions. Generates an execution plan, showing what actions will Terraform take to apply the current configuration. Install the latest module and provider versions allowed within configured constraints, overriding the default behavior of selecting exactly the version recorded in the dependency lockfile. Reconfigure a backend and attempt to migrate any existing state. Reconfigure a backend, ignoring any saved configuration. Optionĭisable backend or Terraform Cloud initialization for this configuration and use what was previously initialized instead. This command is always safe to run multiple times. This sets up all the local data necessary to run Terraform that is typically not committed to version control. This is the first command that should be run for any new or existing Terraform configuration per machine. Initializes a new or existing Terraform working directory by creating initial files, loading any remote state, downloading modules, etc. Prints out a tree of modules in the referenced configuration annotated with their provider requirements. It refers only to the configuration and not accessing any remote services such as remote state, or provider APIs. Validates the configuration files for errors. By default, only the given directory (or current directory) is processed. It does not overwrite the file.Īlso process files in subdirectories. Both configuration files (.tf) and variable files (.tfvars) are updated. Rewrites all Terraform configuration files to a canonical format. Sets up tab auto-completion, requires logging back in. ![]() Just want the cheatsheet? No problem! Please enjoy and if you'd like to submit any suggestions, feel free to email us at tap hashicorp/tapīrew install hashicorp/tap/terraform Terraform CLIĭisplays the version of Terraform and all installed plugins. ![]() By the end you'll be able to provision infrastructure on AWS, secure it, and run EC2 instances and services on those instances. As you learn each concept you'll also put your knowledge into hands-on practice by building real cloud infrastructure from scratch. You'll not only learn to become a top 10% DevOps Engineer or SysAdmin by learning advanced topics most courses don't cover. You'll learn Terraform from actual industry professionals alongside thousands of students in our private Discord community. However, if you're stuck in an endless cycle of YouTube tutorials and want to start provisioning real-world cloud infrastructure, become a professional developer, have fun and actually get hired, then come join the Zero To Mastery Academy. This has made it very popular and is a great tool to learn if you're interested in becoming a DevOps Engineer. It's an open-source Infrastructure as Code (IaC) tool, meaning you can manage your cloud infrastructure using code or configuration files. If you’ve stumbled across this cheatsheet and are just starting to learn about Terraform and cloud infrastructure, you've made a great choice! If you want to get into cloud technologies, Terraform is where you should start.
