# GCP CLI/SDK (Service Account)

## Overview

This guide explains what capabilities StrongDM can provide for managing access to the Google Cloud Platform (GCP) Cloud Console via a service account. It also provides setup and configuration instructions to add GCP as a resource in StrongDM and begin using StrongDM to control access for users who wish to access your GCP console via a CLI application such as gcloud. StrongDM users are authenticated with GCP and granted the level of access that you configure on the GCP side.

In addition to access control and auditing, GCP access through StrongDM can be a part of a variety of use cases and access control methodologies:

* **Least Privilege**: For GCP CLI/SDK (Service Account) clouds, least privilege can be accomplished by setting up multiple instances of the console as StrongDM resources. Each resource would connect to GCP using a different service account with different permissions granted to it.
* **Just-in-Time Access**: StrongDM users are able to use any access workflows you set up to request access to GCP, allowing you the choice between granting Just-in-Time (JIT) access with requests, or providing standing access to particular users or roles within your StrongDM organization. For more details, see the [Access Workflows](https://docs.strongdm.com/admin/access/access-workflows) section.

{% hint style="info" %}
To avoid confusion during access requests, if there are multiple GCP cloud resources in StrongDM, it may be useful to name them in such a way that indicates the level of access, so that users know the name of the resource to request.
{% endhint %}

* **Context-Based Policy**: StrongDM policies that restrict or enable users' ability to connect to GCP resources based on their context can be used to limit availability of your GCP console to users in particular geographic locations or with good device trust scores. Policies can also be used to provide an MFA challenge prior to connection, and help solve for many more use cases. For more details, see the [Policies](https://docs.strongdm.com/admin/access/policies) section.

{% hint style="info" %}
Note that this is a method by which to set up your GCP cloud, and manage it with `gcloud`. If you intend to connect to a specific Google-hosted resource, that resource needs to be set up separately in the appropriate areas of the Admin UI.
{% endhint %}

## Limitations

* There is no SDK, Terraform, Ansible, or other such support for GCP.
* The GCP driver does nothing to limit privilege escalation. It is the responsibility of the resource creator not to provide credentials that can be used to create more credentials.

## GCP Cloud Properties

GCP supports the `gcloud` command-line tool.

## Prerequisites

* In StrongDM, you must have the Admin [permission level](https://docs.strongdm.com/admin/access/permission-level).
* You must have administrator access to your GCP environment and be familiar with `gcloud`.

## Resource Configuration in Google

### Generate credentials

1. In the Google cloud console, [create a service account](https://cloud.google.com/iam/docs/creating-managing-service-accounts).
2. Create a service account key (JSON key file) and save it.

## Resource Configuration in StrongDM

This section provides instructions for adding the resource in either the StrongDM Admin UI, CLI, Terraform provider, or SDKs.

{% tabs %}
{% tab title="Admin UI" %}
**Set up and Manage With the Admin UI**

If using the Admin UI to add the resource to StrongDM, use the following steps.

1. Log in to the Admin UI and go to **Resources** > **Managed Resources**.
2. Click **Add Resource**. Note that there are two types and they have different properties.
3. For **Resource Type**, set **GCP CLI/SDK (Service Account)**.
4. Set all other required [resource properties](#resource-properties).
5. Click **create** to save the resource.
6. Click the resource name to view status, diagnostic information, and setting details. After the server is created, the Admin UI displays that resource as unhealthy until the health checks run successfully. When the resource is ready, the **Health** icon indicates a positive, green status.
   {% endtab %}

{% tab title="CLI" %}
**Set up and Manage With the CLI**

This section provides general steps on how to configure and manage the resource using the StrongDM CLI. For more information and examples, please see the [CLI Reference](https://docs.strongdm.com/references/cli) documentation.

1. In your terminal or Command Prompt, log in to StrongDM:

   ```sh
   sdm login
   ```
2. Run `sdm admin clouds add gcp --help` to view the help text for the command, which shows you how to use the command and what options (properties) are available. Note which [properties](#resource-properties) are required and collect the values for them.\\

   ```
   NAME:
      sdm admin clouds add gcp - create GCP CLI/SDK (Service Account) cloud

   USAGE:
      sdm admin clouds add gcp [command options] <name>

   OPTIONS:
      --bind-interface value                     IP address on which to listen for connections to this resource on clients. Specify "default", "loopback", or "vnm" to automatically allocate an available address from the corresponding IP range configured in the organization. (default: "default")
      --egress-filter value                      apply filter to select egress nodes e.g. 'field:name tag:key=value ...'
      --port-override value                      Port on which to listen for connections to this resource on clients. Specify "-1" to automatically allocate an available port. (default: -1)
      --proxy-cluster-id value                   proxy cluster id
      --scopes value                             Space separated scopes that this login should assume into when authenticating (required)
      --secret-store-id value                    secret store id
      --subdomain value, --bind-subdomain value  DNS subdomain through which this resource may be accessed on clients (e.g. "app-prod" allows the resource to be accessed as "app-prod.<your-org-name>.<sdm-proxy-domain>"). Only applicable to HTTP-based resources or resources using virtual networking mode.
      --svc-keyfile value                        The service account keyfile to authenticate with (required, secret)
      --tags value                               tags e.g. 'key=value,...'
      --template, -t                             display a JSON template
      --timeout value                            set time limit for command
   ```
3. Then run `sdm admin clouds add gcp <RESOURCE_NAME>` and set all required properties with their values. For example:

   <pre><code><strong>$ sdm admin clouds add gcp "gcp-cli-sdk-prod"
   </strong>  --svc-keyfile "/etc/strongdm/keys/gcp-service-account.json"
     --scopes "https://www.googleapis.com/auth/cloud-platform https://www.googleapis.com/auth/userinfo.email"
     --bind-interface "default"
     --port-override -1
     --egress-filter 'field:name tag:env=prod tag:region=us-central'
     --proxy-cluster-id "plc_0123456789abcdef"
     --secret-store-id "ss_abcdef0123456789"
     --subdomain "gcp-cli-prod01"
     --tags "env=prod,cloud=gcp,auth=service-account,team=platform"
     --timeout 30
   </code></pre>
4. Check that the resource has been added. The output of the following command should show the resource's name:

   ```sh
   sdm admin clouds list
   ```

{% endtab %}

{% tab title="Terraform" %}
**Set up and Manage With Terraform**

This section provides an example of how to configure and manage the resource using the Terraform provider. For more information and examples, please see the [Terraform provider](https://github.com/strongdm/terraform-provider-sdm) documentation.

```hcl
# Install StrongDM provider
terraform {
  required_providers {
    sdm = {
      source  = "strongdm/sdm"
      version = "16.5.0"
    }
  }
}

# Configure StrongDM provider
provider "sdm" {
  # Add API access key and secret key from the Admin UI
  api_access_key = "njjSn...5hM"
  api_secret_key = "ziG...="
}

# Create GCP CLI/SDK (Service Account) cloud
resource "sdm_resource" "gcp_cli_sdk_prod" {
  gcp {
    # Required
    name         = "gcp-cli-sdk-prod"                            # <name>
    svc_keyfile  = file("/etc/strongdm/keys/gcp-service-account.json")  # --svc-keyfile (use secret store in production)
    scopes       = "https://www.googleapis.com/auth/cloud-platform https://www.googleapis.com/auth/userinfo.email"  # --scopes

    # Common networking options
    bind_interface = "default"                                   # --bind-interface ("default" | "loopback" | "vnm")
    port_override  = -1                                          # --port-override (-1 = auto-allocate)
    egress_filter  = "field:name tag:env=prod tag:region=us-central"  # --egress-filter
    subdomain      = "gcp-cli-prod01"                            # --subdomain / --bind-subdomain (optional, VN access)

    # Optional integrations
    proxy_cluster_id = "plc_0123456789abcdef"                    # --proxy-cluster-id
    secret_store_id  = "ss_abcdef0123456789"                     # --secret-store-id (recommended for keyfiles)

    # Tags
    tags = {                                                     # --tags
      env   = "prod"
      cloud = "gcp"
      auth  = "service-account"
      team  = "platform"
    }
  }
}
```

{% endtab %}

{% tab title="SDKs" %}
**Set up and Manage With SDKs**

In addition to the Admin UI, CLI, and Terraform, you may configure and manage your resource with any of the following SDK options: Go, Java, Python, and Ruby. Please see the following references for more information and examples.

## Logs

In the **Cloud logs** section of the Admin UI (**Logs** > **Cloud**), you can find all of the activities of the users who accessed the GCP resource. Note that StrongDM makes an attempt to drop the Authorization header of logs for display in the Admin UI. Note that any secrets displayed in the cloud logs are placeholder values. No actual keys or secrets are ever exposed in plaintext in the Admin UI.

## CLI Usage

When the resource is created and configured, you are ready for users to connect to the resource. In order for your organization's users to access the GCP cloud resource via StrongDM, users need to install the following:

* The StrongDM Desktop application
* The latest version of the StrongDM CLI. If the CLI is already installed, you can run `sdm update` in the CLI to update it. Alternatively, if any updates are available, you can open the desktop app and click the **Upgrade** button.
* The `gcloud` command-line tool

After installation, users must exit and restart the desktop app, and then select the GCP cloud resource to connect to.

Click to connect to the resource in the desktop app, or run `sdm connect <RESOURCE>` in the CLI. Once connected, users can use `gcloud` through StrongDM at their terminal, with the base syntax of `sdm gcp` or `sdm gcloud` instead of the usual `gcloud`.

You can use `sdm gcp --help` (or `sdm gcloud --help`) to view example usage and command options:

```shell
NAME:
   sdm gcp - gcp commands

USAGE:
   sdm gcp command [command options] [arguments...]

COMMANDS:
   cli  Execute a gcloud CLI command against a GCP resource.
   env  Print environment variables required to access a GCP resource.
   run  Execute an external command with environment variables configured to access a GCP resource.

OPTIONS:
   --name value     The name of the GCP resource to access. By default if there is only one connected GCP resource, that resource is used. [$SDM_GCP_NAME]
   --project value  The ID of the GCP project to access for project commands. By default, the project configured in the GCP resource is used. (default: "strongdm") [$SDM_GCP_PROJECT]
   --help, -h       show help
```

### gcp cli

The `gcp cli` command is followed by a gcloud CLI command that you wish to run against your connected GCP resource. For more information about gcloud CLI commands, see the [Google Cloud CLI documentation](https://cloud.google.com/sdk/gcloud/reference).

### gcp env

The `gcp env` command outputs the environment variables that are required in order to access a GCP resource. This output is a similar format of the output of the standard `env` command, but only contains the relevant environment variables for connecting to GCP.

### gcp run

The `gcp run` command is followed by a command that you wish to run against the connected resource, which is sent along with the necessary environment variables. An example of a use for `gcp run` would be if you have a pre-existing script for managing GCP resources that uses `gcloud` commands. Instead of altering the script to work with StrongDM, you could use `gcp run shellscript.sh` and run the script.

### --name

If your organization has multiple GCP cloud resources, and you are connected to more than one at once, you may specify a `--name` value in commands in order to specify which you intend to execute the command on. For example, `sdm gcp --name <RESOURCE_NAME> cli`. The flag must come before the `cli` portion of the command in order to preserve the ability to use the command as normal with a single GCP cloud resource connected.

### --project

As a convenience to users, administrators can set a GCP **Project ID** on a resource during configuration. This enables users to skip the `--project` flag when running commands against a GCP CLI/SDK (Workforce Identity Federation) resource. If the **Project ID** field is not filled out during resource configuration, users still need to specify a project in the situations that they normally would when running GCP commands. Either the project number (`95464132584`) or an actual Project ID (`example-favorite-project-1411`) can be used, but Google recommends the Project ID for most cases as the best practice.

## Error Cases

Should you attempt to use a cloud resource without the client running, you encounter an error such as the following:

```shell
ERROR: gcloud crashed (TransportError): HTTPSConnectionPool(host='oauth2.googleapis.com', port=443): Max retries exceeded with url: /token (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x10c7c9d30>: Failed to establish a new connection: [Errno 61] Connection refused')))
```

Should you attempt to use a cloud resource when you are not connected to it, StrongDM's CLI commands warn you. You can get around this warning in some contexts (for example, by setting environment variables in your terminal). In these cases, you may encounter SSL errors, and nothing happens when you run commands.
