+
+## Main Challanges
+
+My main challange is the lack of experience with Azure envrionments.
+
+However, the requiremetns were pretty straight forward, and so, I
+started with reviewing the tools available to work with terrafom and
+Azure.
+The tool that seems to be a good fit, is the [aztexport](https://github.com/Azure/aztfexport)
+utility, which exports an existing azure state into a collecton of
+terraform plan files.
+
+This helped me with understanding the particulars of how azure
+objects/hirarchies/relationships work.
+
+<https://github.com/Azure/azure-cli/issues/11749#issuecomment-570975762>

+# Terraform Utility scripts
+
+The scripts in this directory were made to augment SZs development and
+deployment of it's terraform plans.
+
+They all rely on scaffolding provided by `direnv` and the hirearchy of
+`.envrc` files in the repo which set context relevant environment
+variables which the scripts here interact with to create a cohesive and
+streamlined workflow.
+
+## Typical workflow
+
+Just like working with 'vanilla' terraform, the process follows:
+
+```plaintext
+      +----------------------+-------------------------+
+      V                      | [mostly non-production] |
+    init -> plan -> apply -> | plan-destroy -> apply   |
+              ^       |      +-------------------------+
+              +-------+
+```
+
+With some subtle differences and defaults which are sensible to SZ's
+process, along with persistent logging.
+
+## SZ's workflow
+
+1. `init` - the first step:
+   * Initializes logging timestamp (aka `tf0`)
+   * Preprocess template files (all _sz.*.sz_tmpl files)
+   * Run `terraform init`
+   * Log output into `_logs` sub-directory.
+2. `plan` - The 'brain':
+   * Run `terraform plan` with support for `TF_TARGET`
+     and `TF_TARGET_DESTORY` environment variable.
+   * Generate a `tfplan` file for `apply` action.
+   * Log output into `_logs` sub-directory.
+3. `apply` - The heavy lifting:
+   * Always reads the `tfplan` file.
+   * Used for either _building_ or _destroying_.
+   * Log output into `_logs` sub-directory.
+4. `plan-destroy` - Sensible destory planning:
+   * Initializes logging timestamp (aka `tf0`)
+   * Always layout the plan
+   * Always logged
+   * Supports `TF_TARGET_DESTROY`
+
+## Concepts
+
+* `direnv`'s `.envrc` sets-up the following envrionment variables:
+  * SZ_TF_NAME
+  * SZ_GCP_PROJECT
+  * SZ_GCP_PROJECT_ID
+  * TF_LOG, TF_LOG_PATH
+  * TF_VAR_PLAN_PATH="_.tmp.${SZ_TF_NAME}.tfplan"
+  * TF_VAR_OUT="-out ${TF_VAR_PLAN_PATH}"
+  * TF_VAR_FILE_CLI="-var-file="
+  * TF_VAR_FILE_CLI=""
+
+* `tf-init` pre-processes template files `_sz.*.sz_tmpl`.  
+  it is required first and foremost by `_sz.init.tf.sz_tmpl` which
+  generates the platform initialization code based on the environment
+  set by `direnv` - making sure you are always working with correct
+  gcloud environment.
+  All processed files will have the name pattern `_.gen.*`. Please note
+  that any file begining with `_.` (that's an underscore and a dot) are
+  ignored via `.gitignore`
+
+* All planning is written to a persistent plan
+  (`_.tmp.<tf-plan-name>.tfplan`), whether it's deploying changes, new
+  components or destroying, the tfplan must be generated, along with the
+  log files.
+
+* Logging - Each tf call is logged in 3 parallel locations:
+  * `_logs/0_0_lastrun.log` - the last `tf` run.
+  * `_logs/0_<action>` - the latest run of a terraform action (plan,
+    init, etc...). The rationale here is that all actions of a complete
+    workflow will be easily accessible regardless of timestamps.
+  * `_logs/yyyymmddHHmmss_<action>` - same as above, only timestamped.
+    This allows grouping operations that ran together in sequence,
+    breaking out to a separate sequences (by `tf0`) that will not
+    overwrite previous runs.
+
+* `less-tf` - less with sensible defaults to review latest `tf` run
+  results. If no logs file is specifcied, `_logs/0_0_lastrun.log` will
+  be opened.
+
+## Reference of Scripts
+
+* `tf`:  
+  executes `terraform` while preseving logs including ANSI coloring.
+
+* `tf0`:  
+  same as `tf`, however it will reset the logging timestamp.
+
+* `tf-init`:
+  perform `init` step.
+
+* `tf-plan` or `tfp` or `tf0-plan`
+  perform `plan` step. `tf0-plan` resets timestamp.
+
+* `tf-plan-destroy` or `tfpd`
+  Perform `plan` step for destruction.
+
+* `tf-apply` or `tfa`:  
+  Apply after `plan` step. Unlike `terraform plan` this will not stop to
+  ask for permission, it is based on the preserved planned-state
+  supplied by `tf-plan` (above).
+
+* `tf-extract`:
+  Extracts current state as a json of pairs of names and ids. For use
+  with `tf-import`.
+
+* `tf-import`:
+  Given a json files of name/id pairs, generate an import script for
+  the existing state. This can be used as a non-binary state file.  
+  An example to create such a script from the latest succesful `tf-apply`:
+
+  > ```bash
+  > tf-import _logs/0_9_last_state_ids.json > import-state.sh
+  > ```
