Initial set up

• landingzone_name = path to TF modules directory, i.e. landingzones
• TF_VAR_tf_name = last part of path OR user specify with -tfstate flag
• caf_command="launchpad" this enables LP / Launchpad mode
• tf_action= what was passed to -a i.e. [ plan | apply | destroy ]
• TF_VAR_workspace="tfstate"

🔥 MAJOR TODO! verify login scenario and behavior IS AZ LOGIN ALWAYS USED???

• Call fn - verify_azure_session()
  • runs az account show
• Call fn - process_target_subscription()
  • if -target_subscription flag passed then az account set to that subid
  • target_subscription_name & target_subscription_id obtained from az account command
  • ARM_SUBSCRIPTION_ID=target_subscription_id
  • TF_VAR_tfstate_subscription_id same as ARM_SUBSCRIPTION_ID unless overriden with -tfstate_subscription_id flag
  • In LP mode if TF_VAR_tfstate_subscription_id != ARM_SUBSCRIPTION_ID then EXIT!

Gets terraform_version for reason?

Call fn verify_parameters()

• If in LP mode && landingzone_name UNSET -> Display error and exit
• Ensures TF_VAR_tf_name and TF_VAR_tf_plan are set AGAIN to last segment of landingzone_name with .tfstate and .tfplan appended.

Call fn deploy() -> pass in TF_VAR_workspace Call fn get_storage_id() - Try to find a storage acct in TF_VAR_tfstate_subscription_id WHERE tags match level and environment and set id to it remove local state and plan check if destroy and no storage acct -> error Call fn initialize_state() - Check we are owner on subscription otherwise error and exit - Remove sudo rm -f -- ${landingzone_name}/backend.azurerm.tf I DON@T KNOW WHY! - remove any local state files - set TF_VAR_tf_name and TF_VAR_tf_plan AGAIN! - Call terraform init -upgrade=true in the landingzone_name folder - then calls plan/apply/destroy as per tf_action
