TLS configuration for Supply Chain Security Tools - Store

This topic describes how you can configure TLS for Supply Chain Security Tools (SCST) - Store.

Important

SCST - Store only supports TLS v1.2.

Setting up custom ingress TLS ciphers

In the tap-values.yaml file, tls.server.rfcCiphers are set as shown in the following YAML:

metadata_store:
  tls:
    server:
      rfcCiphers:
        - TLS_AES_128_GCM_SHA256
        - TLS_AES_256_GCM_SHA384
        - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
        - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

Where tls.server.rfcCiphers is a list of cipher suites for the server. Values are from the Go TLS package constants. If you omit values, the default Go cipher suites are used. These are the default values:

• TLS_AES_128_GCM_SHA256
• TLS_AES_256_GCM_SHA384
• TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
• TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

Example custom TLS settings

The following is a complete example of TLS configuration:

metadata_store:
  tls:
    namespace: NAMESPACE
    secretName: SECRET-NAME
    server:
      rfcCiphers:
        - TLS_AES_128_GCM_SHA256
        - TLS_AES_256_GCM_SHA384
        - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
        - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
        - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

Where:

• NAMESPACE is the name of the namespace you want to configure TLS with.
• SECRET-NAME is the name of the secret you want to configure TLS with.
