Future students on the "Infrastructure as a code in Ansible" course , as well as everyone interested, are invited to take part in the open webinar on "Managing Kubernetes with Kubespray" .
And according to the established tradition, we are sharing with you the translation of a useful article.
Terraform is a terrific tool for automating infrastructure management. All parameters of your infrastructure can be written in the form of a code, which will be maintained by the corresponding group. This means that your infrastructure will be transparent and not subject to unexpected changes.

- Finding latest version of hashicorp/vsphere...
- Installing hashicorp/vsphere v1.24.2...
- Installed hashicorp/vsphere v1.24.2 (signed by HashiCorp)
The following providers do not have any version constraints in configuration,
so the latest version was installed.
To prevent automatic upgrades to new major versions that may contain breaking
changes, we recommend adding version constraints in a required_providers block
in your configuration, with the constraint strings suggested below.
* hashicorp/vsphere: version = "~> 1.24.2"
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.
