|
|
Given user-defined infrastructure in Terraform, the provider with its main 'constellation_cluster' resource manages the entire lifecycle of a cluster.

The provider allows easy usage of custom infrastructure setups and GitOps workflows.
|
|
It is released as part of Constellation releases, such that each provider version is compatible with the corresponding Constellation version.`,
