There are two approaches to upgrade you Proxy to a newer version.

In both cases, you should carefully review your next terraform plan or terraform apply for changes to ensure you understand what will be created, modified, or destroyed by the upgrade.

If you have doubts, review CHANGELOG.md for highlights of significant changes in each version; and detailed release notes for each release:

https://github.com/Worklytics/psoxy/releases

Using upgrade-terraform-modules Script

If you originally used one of our example repos (psoxy-example-aws or psoxy-example-gcp, etc), starting from version v0.4.30, you can use the following command leveraging a script creating when you initialized the example:

./upgrade-terraform-modules v0.4.46

This will update all the versions references throughout your example, and offer you a command to revert if you later wish to do so.

Find and replace version references

Open each .tf file in the root of your configuration. Find all module references ending in a version number, and update them to the new version.

Eg, look for something like the following:

module "psoxy" {
  source = "github.com/Worklytics/psoxy//terraform?ref=v0.4.37"
}

update the v0.4.37 to v0.4.46:

module "psoxy" {
  source = "github.com/Worklytics/psoxy//terraform?ref=v0.4.46"
}

Then run terraform init after saving the file to download the new version of each module(s).

This guide provides a roadmap of a typical implementation with Worklytics-provided support.

1 Kick-off/Scoping meeting

30-60 min video call to get overview of process, responsibilities

Attendees:

• Product Stakeholder(s)

• Data Source Administrator(s), if identified

• IT Admin(s), if identified

Agenda:

• determine data sources, and who can authorize access to each

• determine host platform (GCP or AWS)

• identify who has the permissions to manage infra, will be able to run Terraform, and how they'll run it (where, authenticated how)

• scope desired data interval, approximate headcount, etc.

• identify any potential integration issues or infrastructure constraints

2 Initial Walk through

1-2 hr video call, to walk-through customization and initial terraform runs via screenshare

Attendees:

• IT Admin(s) who will be running Terraform

• Worklytics technical contact

Prior to this call, please follow the initial steps in the Getting Started section for your host platform and ensure you have all Prereqs

Goals:

1. get example customized and a terraform plan working.

2. run terraform apply. Obtain the TODO 1 files you can send to your data source administrators to complete, as needed.

Tips:

• Works best if we screenshare

3 Testing / Validation

can be completed without call; but Worklytics can assist if desired

• follow TODO 2 files / use test.sh shell scripts produced by terraform apply

• validate that authentication/authorization is correct for all connections, and that you're satisfied with proxy behavior

4 Authorize Worklytics to Access Sanitized Data

can be completed without call; but Worklytics can assist if desired

Authorize Worklytics to invoke API connectors / access sanitized bulk data:

• obtain service account ID of your tenant from Worklytics; configure it in you terraform.tfvars file

• run terraform apply again to update IAM policy to reflect the change

5 Connect Sanitized Data Sources to Worklytics

can be completed without call; but Worklytics can assist if desired

• follow TODO 3 files (or terraform output values) generated by the terraform apply command

• if you do not have access to Worklytics, or you do, but do not have Data Connection Admin role, send these files to the appropriate person

If you're using Terraform Cloud or Enterprise, here are a few things to keep in mind.

NOTE: this is tested only for gcp; for aws YMMV, and in particular we expect Microsoft 365 sources will not work properly, given how those are authenticated.

Getting Started

Prereqs:

• git/java/maven, as described here https://github.com/Worklytics/psoxy#required-software-and-permissions

• for testing, you'll need the CLI of your host environment (eg, AWS CLI, GCloud CLI, Azure CLI) as well as npm/NodeJS installed on your local machine

After authenticating your terraform CLI to Terraform Cloud/enterprise, you'll need to:

1. Create a Project in Terraform Cloud; and a workspace within the project.

2. Clone one of our example repos and run the ./init script to initialize your terraform.tfvars for Terraform Cloud. This will also put a bunch of useful tooling on your machine.

3. Commit the bundle that was output by the ./init script to your repo:

1. Change the terraform backend main.tf to point to your Terraform Cloud rather than be local

   • remove backend block from main.tf

   • add a cloud block within the terraform block in main.tf (obtain content from your Terraform Cloud)

2. run terraform init to migrate the initial "local" state to the remote state in Terraform Cloud

3. You'll have to authenticate your Terraform Cloud with Google / AWS / Azure, depending on the cloud you're deploying to / data sources you're using.

TODOs as Outputs

If you're using Terraform Cloud or Enterprise, our convention of writing "TODOs" to the local file system might not work for you.

To address this, we've updated most of our examples to also output todo values as Terraform outputs, todos_1, todos_2, etc.

To get them nicely on your local machine, something like the following:

Terraform API

1. get an API token from your Terraform Cloud or Enterprise instance (eg, https://developer.hashicorp.com/terraform/cloud-docs/users-teams-organizations/api-tokens).

2. set it as an env variable, as well as the host:

1. run a curl command using those values to get each todos:

Terraform CLI

If you have terraform CLI auth'd against your Terraform Cloud or Enterprise instance, then you might be able to avoid the curl-hackery above, and instead use the following:

(This approach should also work with Terraform CLI running with backend, rather than cloud)

Testing Locally

If you have run our init script locally (as suggested in 'Getting Started') then the test tool should have been installed (likely at .terraform/modules/psoxy/tools/). You will need to update everything in todos_2.md to point to this path for those test commands to work.

If you need to directly install/re-install it, something like the following should work:

Guides

Done with your Psoxy deployment?

Terraform makes it easy to clean up when you're through with Psoxy, of you wish to rebuild everything from scratch.

First, a few caveats:

• this will NOT undo any changes outside of Terraform, even those we instructed you to perform via TODO - files that Terraform may have generated.

• be careful with anything you created outside of Terraform and later imported into Terraform, such as GCP project / AWS account themselves. If you DON'T want to destroy these, do terraform state rm <resource> (analogue of the import) for each.

Do the following to destroy your Psoxy infra:

1. open you main.tf of your terraform confriguation; remove ALL blocks that aren't terraform, or provider. You'll be left with ~30 lines that looks like the following.

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.12"
    }

    azuread = {
      version = "~> 2.0"
    }
  }

  backend "local" {
  }
}

provider "aws" {
  region = var.aws_region

  assume_role {
    role_arn = var.aws_assume_role_arn
  }
  allowed_account_ids = [
    var.aws_account_id
  ]
}

provider "azuread" {
  tenant_id = var.msft_tenant_id
}

NOTE: do not edit your terraform.tfvars file or remove any references to your AWS / Azure / GCP accounts; Terraform needs be authenticated and know where to delete stuff from!

1. run terraform apply. It'll prompt you with a plan that says "0 to create, 0 to modify" and then some huge number of things to destroy. Type 'yes' to apply it.

That's it. It should remove all the Terraform infra you created.

1. if you want to rebuild from scratch, revert your changes to main.tf (git checkout main.tf) and then terraform apply again.

By default, the Terraform examples provided by Worklytics install a NodeJS-based tool for testing your proxy deployments.

Full documentation of the test tool is available here. And the code is located in the tools directory of the Psoxy repository.

Testing Pre-requisites

Wherever you run this test tool from, your AWS or GCloud CLI must be authenticated as an entity with permissions to invoke the Lambda functions / Cloud functions that you deployed for Psoxy.

If you're testing the bulk cases, the entity must be able to read/write to the cloud storage buckets created for each of those bulk examples.

Testing Locally when Terraform ran remotely (eg, Terraform Cloud, GitHub Actions, etc)

If you're running the Terraform examples in a different location from where you wish to run tests, then you can install the tool alone:

1. Clone the Psoxy repo to your local machine:

git clone https://github.com/Worklytics/psoxy.git

1. From within that clone, install the test tool:

./tools/install-test-tool.sh

1. Get specific test commands for your deployment

   • If you set the todos_as_outputs variable to true, your Terraform apply run should contain todo2 output variable with testing instructions.

   • If you set todos_as_local_files variable to true, your Terraform apply run should contain local files named TODO 2 ... with testing instructions.

   In both cases, you will need to replace the test tool path included there with the path to your installation.

2. Example commands of the primary testing tool: "Psoxy Test Calls"

# GCP deployment example:
node cli-call.js -u https://us-central1-acme.cloudfunctions.net/calendar/v3/calendars/primary -t <IDENTITY_TOKEN> -i user@acme.com
# AWS deployment example:
node cli-call.js -u https://acme.lambda-url.us-east-1.on.aws/v2/users -r arn:aws:iam::310635719553:role/PsoxyApiCaller

Testing Deployments made without Terraform

If you used and approach other than Terraform, or did not directly use our Terraform examples, you may not have the testing examples or the test tool installed on your machine.

In such a case, you can install the test tool manually by following steps 1+2 above, and then can review the documentation on how to use it from your machine.

Overview

This document describes how to migrate your deployment from one cloud provider to another, or one project/account to another. It does not cover migrating between proxy versions.

Use cases:

• move from a dev account to a prod account (Account / Project Migration)

• move from a "shared" account to a "dedicated" account (Account / Project Migration)

• move from AWS --> GCP, and vice versa (Provider Migration)

Preparation

Preserving Existing Infrastructure

Some data/infrastructure MUST, or at least SHOULD be preserved during your migration. Below is an enumeration of both cases.

Data, such as configuration values, can generally be copied; you just need to make a new copy of it in the new environment managed by the new Terraform configuration.

Some infrastructure, such as API Clients, will be moved; eg, the same underlying resource will continue to exist, it will just be managed by the new Terraform configuration instead of the old one. This is the more tedious case, as you must both import this infrastructure to your new configuration and then rm (remove) it from your old configuration, rather than having it be destroyed when you teardown the old configuration. You should carefully review every terraform apply, including terraform destroy commands, to ensure that infrastructure you intend to move is not destroyed, or replaced (eg, terraform sees it as tainted, and does a destroy + create within a single apply operation).

What you MUST copy:

• SALT value. This is a secret used to generate the pseudonyms. If this is lost/destroyed, you will be unable to link any data pseudonymized with the original salt to data you process in the future.

  • NOTE: the underlying resource to preserve is actually a random_password resource, not an SSM parameter / GCP Secret - because those simply are being filled from the terraform random_password resource; if you import parameter/secret, but not the random_password, Terraform will generate a new value and overwrite the parameter/secret.

  • as of v0.4.35 examples, the terraform resource ID for this value is expected to be module.psoxy.module.psoxy.random_password.pseudonym_salt; if not, you can search for it with terraform state list | grep random_password

• value for PSEUDONYMIZE_APP_IDS. This value, if set to true will have the proxy use a rule set that pseudonymizes identifiers issued by source applications themselves in some cases where these identifiers aren't inherently PII - but the association could be considered discoverable.

• value for EMAIL_CANONICALIZATION. prior to v0.4.52, this default was in effect STRICT; so if your original deployment was built on a version prior to this, you should explicitly set this value to STRICT in your new configuration (likely email_canonicalization variable in terraform modules)

• any custom sanitization rules that you've set, either in your Terraform configuration or directly as the value of a RULES environment variable, SSM Parameter, or GCP Secret.

• historical sanitized files for any bulk connectors, if you wish to continue to have this data analyzed by Worklytics. (eg, everything from all your -sanitized buckets)

NOTE: you do NOT need to copy the ENCRYPTION_KEY value; rotation of this value should be expected by clients.

What you SHOULD move:

• API Clients. Whether generated by Terraform or not, the "API Client" for a data source must typically be authorized by a data source administrator to grant it access to the data source. As such, if you destroy the client, or lose its id, you'll need to coordinate with the administrator again to recreate it / obtain the configuration information.

  • as of v0.4.35, Google Workspace and Microsoft 365 API clients are managed directly by Terraform, so these are important to preserve.

What you SHOULD copy:

• API Client Secrets, if generated outside of Terraform. If you destroy/lose these values, you'll need to contact the data source administrator to obtain new versions.

Prior to beginning your migration, you should make a list of what existing infrastructure and/or configuration values you intend to move/copy.

Migration Plan

The following is a rough guide on the steps you need to take to migrate your deployment.

Phase 1 : Gather information from Existing Environment

1. Salt value. If using an example forked from our template repos at v0.4.35 or later, you can find the output block in your main.tf for pseudonym_salt, uncomment it, run terraform apply. You'll then be able to obtain the value with: terraform output --raw pseudonym_salt On macOS, you can copy the value to your clipboard with: terraform output --raw pseudonym_salt | pbcopy

2. Microsoft 365 API client, if any:

   • Find the resource ids: terraform state list | grep "\.azuread_application\."

   • For each, obtain it's objectId: terraform state show 'module.psoxy.module.msft-connection["azure-ad"].azuread_application.connector'

   • Prepare import command for each client for your new configuration, eg: terraform import 'module.psoxy.module.msft-connection["azure-ad"].azuread_application.connector' '<objectId>'

3. Google Workspace API clients, if any:

   • Find the resource ids: tf state list | grep 'google_service_account\.connector-sa'

   • For each, obtain its unique_id: terraform state show 'module.worklytics_connectors_google_workspace.module.google_workspace_connection["gdirectory"].google_service_account.connector-sa'

   • Prepare import command for each client for your new configuration, eg: terraform import 'module.worklytics_connectors_google_workspace.module.google_workspace_connection["gdirectory"].google_service_account.connector-sa' '<unique_id>'

Phase 2 : Create New Environment

1. Create a new Terraform configuration from scratch; run terraform init there (if you begin with one of our examples, our init script does this). Use the terraform.tfvars of your existing configuration as a guide for what variables to set, copying over any needed values.

2. Run a provisional terraform plan and review.

3. Run the imports you prepared in Phase 1, if all appear OK, run another terraform plan and review (comparing to the old one).

4. Optionally, run terraform plan -out=plan.out to create a plan file; if you send this, along with all the *.tf/*.tfvars files to Worklytics, we can review it and confirm that it is correct.

5. Run terraform apply to create the new infrastructure; re-confirm that the plan is not re-creating any API clients/etc that you intended to preserve

6. Via AWS / GCP console, or CLIs, move the values of any secrets/parameters that you intend to by directly reading the values from your old account/project, and copying them into the new account/project

Phase 3: Migrate

1. Look at the TODO 3 files/output variables for all your connectors. Make a mapping between the old values and the new values. Send this to Worklytics. It should include for each the proxy URLs, AWS Role to use, and any other values that are changing.

2. Wait for confirmation that Worklytics has migrated all your connections to the new values. This may take 1-2 days.

Phase 4: Destroy Old Environment

1. Remove references to any API Clients you migrated in Phase 1:

   • eg, terraform state rm 'module.psoxy.module.msft-connection["azure-ad"].azuread_application.connector'

2. run terraform destroy in the old configuration. Carefully review the plan before confirming.

   • if you're using Google Workspace sources, you may see destruction of google_project_service resources; if you allow these to be destroyed, these APIS will be disabled; if you are using the same GCP project in your other configuration, you should run terraform apply there again to re-enable them.

3. You may also destroy any API clients/etc that are managed outside of Terraform and which you did not migrate to the new environment.

4. You may clean up any configuration values, such as SSM Parameters / GCP Secrets to customize the proxy rules sets, that you may have created in your old host environment.
