Package infra provides cloud infrastructure management for Go programs. The package includes facilities for configuring, provisioning, and migrating cloud infrastructure that is used by a Go program. You can think of infra as a simple, embedded version of Terraform, combined with a self-contained dependency injection framework.

Infrastructure managed by this package is exposed through a configuration. Configurations specify which providers should be used for which infrastructure component; configurations also store provider configuration and migration state. Users instantiate typed values directly from the configuration: the details of configuration and of managing dependencies between infrastructure components is handled by the config object itself. Configurations are marshaled and must be stored by the user.

Infrastructure migration is handled by maintaining a set of versions for each provider; migrations perform side-effects and can modify the configuration accordingly (e.g., to store identifiers used by the cloud infrastructure provider).
