                  Note

                  This is a Tagged Union structure. Only one of the following top level keys will be set: file, sds. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

                  'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

                  • file (dict) –

                    An object that represents a Transport Layer Security (TLS) validation context trust for a local file.

                    • certificateChain (string) –

                      The certificate trust chain for a certificate stored on the file system of the virtual node that the proxy is running on.

                  • sds (dict) –

                    A reference to an object that represents a virtual gateway’s listener’s Transport Layer Security (TLS) Secret Discovery Service validation context trust.

                    • secretName (string) –

                      A reference to an object that represents the name of the secret for a virtual gateway’s Transport Layer Security (TLS) Secret Discovery Service validation context trust.

          An object that represents logging information.

          • accessLog (dict) –

            The access log configuration.

            Note

            This is a Tagged Union structure. Only one of the following top level keys will be set: file. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

            'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

            • file (dict) –

              The file object to send virtual gateway access logs to.

              • format (dict) –

                The specified format for the virtual gateway access logs. It can be either json_format or text_format.

                Note

                This is a Tagged Union structure. Only one of the following top level keys will be set: json, text. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

                'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

                • json (list) –

                  • (dict) –

              • path (string) –

                The file path to write access logs to. You can use /dev/stdout to send access logs to standard out and configure your Envoy container to use a log driver, such as awslogs, to export the access logs to a log storage service such as Amazon CloudWatch Logs. You can also specify a path in the Envoy container’s file system to write the files to disk.

      • status (dict) –

        The current status of the virtual gateway.

        • status (string) –

          The current status.
