terraform init is used to initialize a working directory containing Terraform configuration files.
During terraform init, the configuration is searched for module blocks, and the source code for referenced modules is retrieved from the locations given in their source arguments.
It is safe to run this command multiple times.

If you forget, other commands will detect it and remind you to do so if necessary.

Execution with errors
terraform init Terraform initialized in an empty directory! The directory has no Terraform configuration files. You may begin working with Terraform immediately by creating Terraform configuration files.

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
Warning: Interpolation-only expressions are deprecated
on kk.tf line 7, in data "vsphere_datastore" "datastore":
7: datacenter_id = "${data.vsphere_datacenter.dc.id}"
Terraform 0.11 and earlier required all non-constant expressions to be
provided via interpolation syntax, but this pattern is now deprecated. To
silence this warning, remove the "${ sequence from the start and the }"
sequence from the end of this expression, leaving just the inner expression.
Template interpolation syntax is still used to construct strings from
expressions when the template includes multiple interpolation sequences or a
mixture of literal strings and interpolations. This deprecation applies only
to templates that consist entirely of a single interpolation sequence.
(and 5 more similar warnings elsewhere)
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
