feat: platform SecretStack with AWS and Vault backends - #28
Conversation
Break the API group to hops.ops.com.ai and select secrets backend via spec.backend (aws|vault). Gate PodIdentity and SM stores on aws; add optional Vault Helm install plus Vault SecretStore. Gate dependents on sticky helm revision existence rather than Ready. Dogfooded locally with hops config install --path against dory (ESO + Vault Releases Ready).

External Secrets Operator AWS Secrets Manager provider documentation BatchGetSecretValue dataFrom path tag filter required IAM permissions
💡 Result:
The External Secrets Operator (ESO) AWS Secrets Manager provider automatically leverages the BatchGetSecretValue API to optimize performance and reduce API call costs [1][2]. Usage of BatchGetSecretValue: - When using dataFrom, the provider will utilize BatchGetSecretValue if you define a path prefix or filter by Tags [1][3]. - If you use dataFrom without defining a path (e.g., searching by name only), the provider falls back to the less efficient ListSecrets API, which then requires fetching each secret individually [1][2][4]. Required IAM Permissions: To support these operations, your IAM policy must include the following permissions [1][5]: - secretsmanager:ListSecrets: Necessary for the operator to discover secrets [1][5]. - secretsmanager:BatchGetSecretValue: Required to retrieve multiple secret values efficiently [1][5]. - secretsmanager:GetSecretValue, secretsmanager:DescribeSecret, and secretsmanager:ListSecretVersionIds: Required for accessing the details and versions of the specific secrets being managed [1][5]. The official documentation provides a recommended IAM policy structure that allows ListSecrets and BatchGetSecretValue on all resources ("*") while scoping the more sensitive read/describe actions to the specific ARNs of the secrets you are managing [1][5].

AWS Secrets Manager BatchGetSecretValue IAM policy Resource required condition keys official documentation
💡 Result:
According to official AWS documentation, the secretsmanager:BatchGetSecretValue IAM action does not support resource-level permissions [1]. Because it is a batch operation that can retrieve multiple secrets in a single call, it is typically granted with "Resource": "*" in IAM identity-based policies [1][2][3]. Key details regarding IAM requirements for BatchGetSecretValue: 1. Resource Level: The action does not support resource-specific constraints within the BatchGetSecretValue statement itself, meaning it must be set to "*" [1]. 2. Security Enforcement: Access control is enforced at the individual secret level [4]. To successfully retrieve secrets, the IAM principal must additionally have secretsmanager:GetSecretValue permissions granted on the specific secret resources they are authorized to access [5][4]. 3. Condition Keys: There are no specific resource-required condition keys for BatchGetSecretValue listed in the service authorization reference [1]. While you can use AWS global condition keys (such as aws:SourceAccount or aws:SourceArn) in policies, these are not unique to or specifically required by this action [6][7]. Example Pattern: To grant secure access, follow the pattern of allowing BatchGetSecretValue globally, while explicitly restricting GetSecretValue to the specific secret ARNs required by the user or application [2][3]: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "secretsmanager:BatchGetSecretValue", "secretsmanager:ListSecrets" ], "Resource": "*" }, { "Effect": "Allow", "Action": "secretsmanager:GetSecretValue", "Resource": [ "arn:aws:secretsmanager:region:account-id:secret:secret-name-1", "arn:aws:secretsmanager:region:account-id:secret:secret-name-2" ] } ] }

External Secrets Operator AWS Secrets Manager provider IAM permissions GetSecretValue DescribeSecret ListSecrets BatchGetSecretValue and AWS IAM Secrets Manager resource-policy actions permissions management
💡 Result:
The External Secrets Operator (ESO) requires specific AWS IAM permissions to interact with AWS Secrets Manager, depending on whether you are simply syncing secrets or also managing them (e.g., using PushSecret) [1][2]. Standard Secret Retrieval Permissions To fetch secrets, the IAM identity (e.g., a Kubernetes Service Account via IRSA) requires: - secretsmanager:GetSecretValue: Required to retrieve the secret's encrypted content [3][4]. - secretsmanager:DescribeSecret: Required to access secret metadata [2][4]. - secretsmanager:ListSecrets: Required if you are using batch retrieval or filters [5][6][4]. - secretsmanager:BatchGetSecretValue: Required to retrieve multiple secrets in a single call [5][4]. - kms:Decrypt: If the secret is encrypted with a customer-managed KMS key (rather than the default AWS-managed key), this permission is also required for that specific key [3][5]. Permissions for Managing Secrets (PushSecret) If you utilize the PushSecret feature to create or update secrets, additional permissions are necessary: - Required: secretsmanager:CreateSecret, secretsmanager:PutSecretValue, and secretsmanager:TagResource [1][7]. - Optional (for policy management): If you use the resourcePolicy metadata option in ESO, you need secretsmanager:GetResourcePolicy, secretsmanager:PutResourcePolicy, and secretsmanager:DeleteResourcePolicy [1][2]. - Optional (for replication): If using replicationLocations, you need secretsmanager:ReplicateSecretToRegions and secretsmanager:RemoveRegionsFromReplication [1][7]. AWS IAM Resource-Policy Actions and Management Resource-based policies allow you to explicitly define which IAM principals can access a specific secret [8]. - Key Actions: The primary action for modifying these policies is secretsmanager:PutResourcePolicy [9][10]. Other relevant actions include secretsmanager:GetResourcePolicy and secretsmanager:DeleteResourcePolicy [1][2]. - Security Best Practices: Use the BlockPublicPolicy parameter when calling PutResourcePolicy to prevent granting overly permissive (e.g., wildcard) access to secrets [8][9]. Because secretsmanager:PutResourcePolicy can be used to escalate permissions, it should be restricted to highly privileged roles following the principle of least privilege [10]. - Validation: AWS utilizes automated reasoning (Zelkova) to validate resource-based policies during creation to prevent accidental exposure [8]. Finally, if you are using IAM Roles for Service Accounts (IRSA) or Pod Identity, ensure the trust policy of the IAM role allows the necessary service principals to perform sts:AssumeRole and, if applicable, sts:TagSession [11].

site:docs.aws.amazon.com Secrets Manager KMS kms:ViaService kms:EncryptionContext:SecretARN least privilege policy
💡 Result:
To implement least-privilege access for AWS Secrets Manager using AWS KMS, you should restrict the use of your customer managed KMS key by incorporating the kms:ViaService and kms:EncryptionContext:SecretARN condition keys into your key policy or IAM policy [1][2]. The kms:ViaService condition key limits the use of the KMS key to requests originating exclusively from the Secrets Manager service [3][1]. In your policy, set the condition value to secretsmanager..amazonaws.com (replace with your specific AWS region, or use a wildcard for multi-region access, e.g., secretsmanager..amazonaws.com) [1][4][2]. The kms:EncryptionContext:SecretARN condition key further refines least privilege by ensuring that a principal can only perform cryptographic operations (such as Decrypt) on a specific secret [3][5]. Because Secrets Manager binds the Secret ARN to the encryption context during encryption, this condition prevents unauthorized access by ensuring the key is only used when the request matches the specific secret ARN provided in the policy [3][2][6]. Example policy statement snippet for a KMS key policy: { "Effect": "Allow", "Action": [ "kms:Decrypt", "kms:DescribeKey" ], "Resource": "", "Condition": { "StringEquals": { "kms:ViaService": "secretsmanager.us-east-1.amazonaws.com", "kms:EncryptionContext:SecretARN": "arn:aws:secretsmanager:us-east-1:111122223333:secret:my-secret-abc123" } } } By combining these conditions, you create a robust defense-in-depth strategy: kms:ViaService ensures the request comes through the authorized service, and kms:EncryptionContext:SecretARN ensures the service is only acting on the exact resource authorized [1][2][6]. This approach is a standard security best practice for managing sensitive credentials [2][6].

site:external-secrets.io/latest/provider/aws-secrets-manager PushSecret required IAM permissions CreateSecret PutSecretValue TagResource resourcePolicy
💡 Result:
To use the PushSecret feature in External Secrets Operator with AWS Secrets Manager, your IAM identity requires specific permissions to manage secrets and their metadata. The required permissions include [1]: - secretsmanager:CreateSecret: To create the secret if it does not already exist. - secretsmanager:PutSecretValue: To update the value of the secret. - secretsmanager:TagResource: To apply tags to the secret. Additional permissions may be required based on your specific configuration: - Resource Policy Management: If you use the resourcePolicy metadata option to manage resource-based policies on the secret, you must also include secretsmanager:GetResourcePolicy, secretsmanager:PutResourcePolicy, and secretsmanager:DeleteResourcePolicy [1]. - Replication: If you use the replicationLocations metadata option, you must include secretsmanager:ReplicateSecretToRegions and secretsmanager:RemoveRegionsFromReplication [1]. - Deletion: The secretsmanager:DeleteSecret permission is typically included to allow the operator to manage the lifecycle of the secrets it creates [1]. It is recommended to restrict these permissions to specific resources using ARNs to follow the principle of least privilege [1].

resources::pod_identity embeds this policy in the ESO workload role. The role allows reads from all Secrets Manager secrets, decrypts with all KMS keys, and reads all SSM parameters. secretsmanager:* also permits destructive and resource-policy actions on every push/* secret.
Generate the policy with approved SecretStack prefixes and KMS ARNs. Replace secretsmanager:* with only the actions required by configured ESO features. Add kms:ViaService and kms:EncryptionContext:SecretARN conditions for customer-managed keys. Remove unused SSM permissions.

HashiCorp Vault Helm chart dev mode tlsDisable dataStorage Kubernetes auth enable configure role official documentation
💡 Result:
The following information outlines the configuration for the HashiCorp Vault Helm chart based on official HashiCorp documentation [1][2][3]. Dev Mode and TLS Vault's 'dev' mode is designed for experimentation and is insecure for production use [1][4]. By default, 'dev' mode uses HTTP, and the Helm chart does not natively support enabling TLS while simultaneously using 'dev' mode [5]. To enable TLS, you generally must run in 'standalone' or 'ha' (Raft) mode and configure the listener explicitly [6][7]. To set dev mode, use the following in your values.yaml: server: dev: enabled: true Data Storage For persistent storage (required for standalone and HA/Raft modes), configure the 'dataStorage' block [2][8]. This ensures that a PersistentVolumeClaim (PVC) is created for Vault's data [7][8]. server: dataStorage: enabled: true size: "10Gi" storageClass: null # Uses cluster default if null Kubernetes Auth Method To enable and configure the Kubernetes auth method: 1. Enable the method in Vault: vault auth enable kubernetes 2. Configure the auth method to communicate with the Kubernetes API. If Vault is running within the same cluster, it can automatically detect the necessary credentials [9]: vault write auth/kubernetes/config \ kubernetes_host=https://$KUBERNETES_SERVICE_HOST:$KUBERNETES_SERVICE_PORT 3. Configure roles to define access policies: vault write auth/kubernetes/role/ \ bound_service_account_names= \ bound_service_account_namespaces= \ policies= \ ttl=24h Helm Configuration The Helm chart also provides an 'authDelegator' option to automatically set up the necessary ClusterRoleBindings for the Kubernetes auth method [3]: server: authDelegator: enabled: true Security Warning: Never run 'dev' mode in production; all data is lost upon restart [1][4]. For production environments, use 'standalone' or 'ha' (Raft) modes with proper persistent storage and TLS configuration [6][2][7].

Bootstrap and secure the installed Vault.
When vault_install is true, the defaults run Vault in dev mode over HTTP with storage disabled. EffectiveState::from_spec defaults the SecretStore to Kubernetes authentication, but no Kubernetes auth mount, configuration, role, or policy is created. The SecretStore renders after both Helm releases exist, so ESO authentication fails.
Render an idempotent Vault bootstrap and gate the SecretStore on its completion, or require a preconfigured Vault. Use persistent storage and TLS in non-dev mode, and configure the SecretStore endpoint and CA settings accordingly.

helm_vault and the related vault_install resource flow to run Vault in non-dev
mode with persistent storage and TLS, then add an idempotent bootstrap that
enables Kubernetes authentication and creates the required auth configuration,
role, and policy. Ensure the SecretStore waits for bootstrap completion and uses
the configured Vault endpoint and CA settings; alternatively require an
explicitly preconfigured Vault when bootstrap is not enabled.
