scenario "pr_replication" {
  description = <<-EOF
    The PR replication scenario configures performance replication between two Vault clusters and
    verifies behavior and failure tolerance. The build can be a local branch, any CRT built Vault
    Enterprise artifact saved to the local machine, or any CRT built Vault Enterprise artifact in
    the stable channel in Artifactory.

    The scenario deploys two Vault Enterprise clusters and establishes performance replication
    between the primary cluster and the performance replication secondary cluster. Next, it simulates
    a catastrophic failure event whereby the primary leader and a primary follower are ungracefully
    removed from the cluster while running. This forces a leader election in the primary cluster
    and requires the secondary cluster to recover replication and establish replication to the new
    primary leader. The scenario also performs standard baseline verification that is not specific
    to performance replication.

    # How to run this scenario

    For general instructions on running a scenario, refer to the Enos docs: https://eng-handbook.hashicorp.services/internal-tools/enos/running-a-scenario/
    For troubleshooting tips and common errors, see https://eng-handbook.hashicorp.services/internal-tools/enos/troubleshooting/.

    Variables required for all scenario variants:
      - aws_ssh_private_key_path (more info about AWS SSH keypairs: https://eng-handbook.hashicorp.services/internal-tools/enos/getting-started/#set-your-aws-key-pair-name-and-private-key)
      - aws_ssh_keypair_name
      - vault_build_date*
      - vault_product_version
      - vault_revision*
    
    * If you don't already know what build date and revision you should be using, see
    https://eng-handbook.hashicorp.services/internal-tools/enos/troubleshooting/#execution-error-expected-vs-got-for-vault-versioneditionrevisionbuild-date.
  
    Variables required for some scenario variants:
      - artifactory_username (if using `artifact_source:artifactory` in your filter)
      - artifactory_token (if using `artifact_source:artifactory` in your filter)
      - aws_region (if different from the default value in enos-variables.hcl)
      - consul_license_path (if using an ENT edition of Consul)
      - distro_version_<distro> (if different from the default version for your target
      distro. See supported distros and default versions in the distro_version_<distro>
      definitions in enos-variables.hcl)
      - vault_artifact_path (the path to where you have a Vault artifact already downloaded,
      if using `artifact_source:crt` in your filter)
      - vault_license_path (if using an ENT edition of Vault)
