SPIRE Secret Manager

Suggest Edit

Prerequisites

Authentication

The following Authentication Methods can be used:

👍

Note

In this guide, we will use an API Key Authentication Method for simplicity and we are only using Linux machines. For MacOS, please see the guide here.

Create a new API Key Authentication Method using the CLI:

akeyless create-auth-method --name /Dev/Spire-Agent-Auth

Create an Access Role:

akeyless create-role --name /Dev/Spire-Agent-Role

Associate your API Key Authentication Method to the Access Role that was created:

akeyless assoc-role-am --role-name /Dev/Spire-Agent-Role \
--am-name /Dev/Spire-Agent-Auth

Set create, list, update permissions for Secret & Keys for the Access Role:

akeyless set-role-rule --role-name /Dev/Spire-Agent-Role \
--path /SPIRE/SVID/'*' \
--capability create --capability update

Configuration

Run the following command to download and unpack pre-built spire-server and spire-agent executables and example configuration files in a spire-1.7.0 directory.

curl -s -N -L https://github.com/spiffe/spire/releases/download/v1.7.0/spire-1.7.0-linux-amd64-glibc.tar.gz | tar xz

Next, download the AkeylessSecretManager plugin, by running the following command:

curl -o AkeylessSecretManager https://download.akeyless.io/Akeyless_Artifacts/Linux/spire/plugin/agent/spire-sm-amd64-linux-v0.0.6
chmod +x AkeylessSecretManager
curl -o AkeylessSecretManager https://download.akeyless.io/Akeyless_Artifacts/Linux/spire/plugin/agent/spire-sm-arm64-linux-v0.0.6
chmod +x AkeylessSecretManager

Validate the SHA256 CHECKSUM:

sha256sum AkeylessSecretManager

The sha256sum command generates a unique, fixed-size hash value (256 bits) for the binary file, ensuring that data remains unchanged.

Open the SPIRE Agent config file in the spire- directory in conf/agent/agent.conf, and add the SVIDStore Plugin under plugins as follows:

SVIDStore "akeyless_secretsmanager" {
    plugin_cmd = "/path/to/plugin_cmd"
    plugin_checksum = "sha256 of the plugin binary"
    plugin_data {
     akeyless_gateway_url = 'https://<Your-Akeyless-GW-URL:8000/api/v2>' # or use port 8081
     access_id = "<Your_Access_ID>"
     access_key = "<Your_Access_KEY>"
     target_folder = "/SPIRE/SVID/"     
   }
}

Where:

  • plugin_cmd - The location of the binary file that was created.

  • plugin_checksum - sha256 of the binary.

  • akeyless_gateway_url - Akeyless Gateway URL API v2 endpoint.

  • access_id - The Auth Method AccessID

  • access_key - Optional, the AccessKey. Relevant only for API Key

  • target_folder - A path to save all items inside Akeyless where the generated SVIDs will be stored

For K8s,GCP or AzureAD Auth method set the following settings as well:

  • k8s_auth_config_name- K8s Auth Config name as created under your Gateway

  • gcp_audience- The audience to verify the JWT received by the client. By default, akeyless.io

  • azure_object_id - Optional for Azure, objectID

SPIRE Agent Initialization

📘

Info

SPIRE Server

You are required to start the SPIRE server before running the Agent commands.

In order to attest the SPIRE agent to the server, create a join token:

bin/spire-server token generate -spiffeID spiffe://example.org/myagent
Token: <token_string>

Make a note of the token, you will need it in the next step to attest the agent on initial startup.

Attest the SPIRE agent to the SPIRE server:

bin/spire-agent run -config conf/agent/agent.conf -joinToken <token_string> &

Create a registration policy

bin/spire-server entry create -parentID spiffe://example.org/myagent \
-spiffeID spiffe://example.org/myservice -selector akeyless_secretsmanager:secretname:<Secret Name> -storeSVID

Upon successful registration of the workload, a secret will be created in Akeyless in the /SPIRE/SVID/ folder, which will contain the following information:

  • SpiffeID
  • Certificate
  • x509SVIDKey
