# Provisioning Infrastructure with OpenTofu
|
|
|
|
OpenTofu's primary function is to create, modify, and destroy infrastructure
|
|
resources to match the desired state described in a
|
|
[OpenTofu configuration](../../language/index.mdx).
|
|
|
|
When people refer to "running OpenTofu," they generally mean performing these
|
|
provisioning actions in order to affect real infrastructure objects. The
|
|
OpenTofu binary has many other subcommands for a wide variety of administrative
|
|
actions, but these basic provisioning tasks are the core of OpenTofu.
|
|
|
|
OpenTofu's provisioning workflow relies on three commands: `plan`, `apply`, and
|
|
`destroy`. All of these commands require an
|
|
[initialized](../../cli/init/index.mdx) working directory, and all of them act
|
|
only upon the currently selected [workspace](../../cli/workspaces/index.mdx).
|
|
|
|
## Planning
|
|
|
|
The `tofu plan` command evaluates a OpenTofu configuration to determine
|
|
the desired state of all the resources it declares, then compares that desired
|
|
state to the real infrastructure objects being managed with the current working
|
|
directory and workspace. It uses state data to determine which real objects
|
|
correspond to which declared resources, and checks the current state of each
|
|
resource using the relevant infrastructure provider's API.
|
|
|
|
Once it has determined the difference between the current state and the desired
|
|
state, `tofu plan` presents a description of the changes necessary to
|
|
achieve the desired state. It _does not_ perform any actual changes to real
|
|
world infrastructure objects; it only presents a plan for making changes.
|
|
|
|
Plans are usually run to validate configuration changes and confirm that the
|
|
resulting actions are as expected. However, `tofu plan` can also save its
|
|
plan as a runnable artifact, which `tofu apply` can use to carry out those
|
|
exact changes.
|
|
|
|
For details, see [the `tofu plan` command](../../cli/commands/plan.mdx).
|
|
|
|
## Applying
|
|
|
|
The `tofu apply` command performs a plan just like `tofu plan` does,
|
|
but then actually carries out the planned changes to each resource using the
|
|
relevant infrastructure provider's API. It asks for confirmation from the user
|
|
before making any changes, unless it was explicitly told to skip approval.
|
|
|
|
By default, `tofu apply` performs a fresh plan right before applying
|
|
changes, and displays the plan to the user when asking for confirmation.
|
|
However, it can also accept a plan file produced by `tofu plan` in lieu of
|
|
running a new plan. You can use this to reliably perform an exact set of
|
|
pre-approved changes, even if the configuration or the state of the real
|
|
infrastructure has changed in the minutes since the original plan was created.
|
|
|
|
For details, see [the `tofu apply` command](../../cli/commands/apply.mdx).
|
|
|
|
## Destroying
|
|
|
|
The `tofu destroy` command destroys all of the resources being managed by
|
|
the current working directory and workspace, using state data to determine which
|
|
real world objects correspond to managed resources. Like `tofu apply`, it
|
|
asks for confirmation before proceeding.
|
|
|
|
A destroy behaves exactly like deleting every resource from the configuration
|
|
and then running an apply, except that it doesn't require editing the
|
|
configuration. This is more convenient if you intend to provision similar
|
|
resources at a later date.
|
|
|
|
For details, see [the `tofu destroy` command](../../cli/commands/destroy.mdx).
