Self-signed certificate or no certificate for compute nodes

This is for Sym 7.3.1 or later versions. We need to have TLS enabled for all the communications in order to run Symphony in AWS securely. All the management nodes and masters will have a proper signed certificate. Communications to mgmt nodes and master nodes need to have certificate check enabled to ensure security. However, compute nodes will not have a certificate or will only have self-signed certificate. We need suggestions/instructions to get this working.

    it seems the case could be already supported by existing configurations as described in as follow:

    1. PEM will work as server in several requests cases (like VEMKD start/signal container) so the CERTIFICATE and PRIVATE_KEY will be used by PEM as VEMKD may actively connect to PEM - so then you will need to use in ego.conf on management hosts parameter EGO_PEM_TS_PARAMS which will be propagated and used by all PEMs to configure: the self-signed certificate, with corresponding private key, and 3rd party certificate’s CA file

    2. Then for the same ego.conf on management hosts in parameter EGO_KD_PEM_TS_PARAMS which is used by VEMKD, configure: the 3rd party certificate, corresponding private key, and the self-signed certificate’s CA file.

    3. For SOAM layer there should be no changes required because SIM as client only need the CA file and does not need the certificate file on compute nodes.
