Kubernetes Secrets Management Tools -- Akeyless Alternatives

Best Kubernetes Secrets Management Tools in 2026

Managing secrets in Kubernetes requires tools that integrate natively with pods, operators, and service meshes. These tools inject secrets directly into containers, support automatic rotation, and eliminate the need for hardcoded credentials in your cluster configurations.

How It Works

1

Install the Secrets Operator

Deploy the secrets management operator or CSI driver to your Kubernetes cluster using Helm or kubectl. This component acts as the bridge between your secrets manager and Kubernetes.

2

Configure Authentication

Set up authentication between your Kubernetes cluster and the secrets manager. This typically involves Kubernetes service accounts, OIDC federation, or managed identity (for cloud providers).

3

Define Secret References

Create SecretProviderClass or ExternalSecret custom resources that map external secrets to Kubernetes secrets. Define which secrets your workloads need and how they should be mounted.

4

Mount Secrets to Pods

Reference the synced Kubernetes secrets in your pod specs as environment variables or volume mounts. Secrets are automatically injected when pods start.

5

Enable Rotation & Monitoring

Configure automatic rotation policies and set up monitoring for secret access. Most operators support automatic re-sync when external secrets change, triggering rolling updates.

Kubernetes Secrets Management Tools FAQ

Why shouldn't I use native Kubernetes secrets?

Native Kubernetes secrets are base64-encoded (not encrypted) by default, stored in etcd, and lack rotation, auditing, and fine-grained access control. External secrets managers add encryption at rest, automatic rotation, centralized audit logging, and the ability to share secrets across clusters and non-Kubernetes workloads.

What is the Kubernetes Secrets Store CSI Driver?

The Secrets Store CSI Driver is a Kubernetes-native mechanism that allows you to mount secrets from external vaults directly into pods as volumes. It supports providers for HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, and GCP Secret Manager, providing a standardized way to consume external secrets in Kubernetes.

Which tool is easiest to set up in Kubernetes?

Doppler and Infisical offer the simplest Kubernetes setup, with operators that can be deployed via a single Helm chart. HashiCorp Vault is the most powerful but has a steeper learning curve. AWS Secrets Manager is straightforward for EKS clusters using the ASCP provider.

Can I use multiple secrets managers with one Kubernetes cluster?

Yes. The External Secrets Operator (ESO) supports multiple backend providers simultaneously, allowing you to pull secrets from different sources into a single cluster. This is useful in multi-cloud or hybrid environments where secrets live in different systems.
