Provision an Azure Service Principal (SP) (Consider the official flux documentation for a detailed walk-through). To decrypt secrets with SOPS in Kubernetes (for example, if you use a GitOps operator such as Flux), you should consider using a combination of Managed Service Identity (MSI) and Azure AD Pod Identity. Here are the five most popular supported scenarios:įor authenticating against Azure Key Vault, SOPS tries several authentication patterns in the following order:Īlthough Azure CLI authentication is frictionless, I would encourage you to use an Azure Service Principal (SP) on your local development machine. SOPS supports multiple backends to consume keys for encryption and decryption.
Mozilla SOPS ( Secrets OPeration S) is a platform-agnostic CLI that is used to edit encrypted files of different formats - including yaml, json, ini, binary, and others.

This article demonstrates how to encrypt and decrypt Kubernetes secrets ( YAML files) using SOPS in combination with Azure Key Vault, which allows you to store your secrets along with other Kubernetes manifests directly in git. Encrypted secrets will be decrypted locally just before they’ll be deployed to Kubernetes. Secrets that are encrypted via SOPS can be stored in source control. Additionally, depending on the service you use to store your sensitive data, some sensitive configuration must be stored somewhere to configure the CIS driver.Īs an alternative, you can use Mozilla SOPS (SOPS) to encrypt and decrypt your Kubernetes secret files. However, relying on an additional service means that you have to manage and maintain that service in addition to Kubernetes. Those services can be integrated with Kubernetes by using the Secrets Store CIS driver. echo | base64 -d.Ī typical solution is using services like Azure Key Vault, or HashiCorp Vault to persist sensitive data. Obviously, you don’t want to put your sensitive configuration data into a git repository, because it is just encoded. The lack of encryption for secrets often leads to the question of how to store secrets securely. By default, Kubernetes Secrets (secrets) are stored with base64 encoding in YAMLfiles.
