-- Citus uses ssl by default now. It does so by turning on ssl and if needed will generate
|
|
-- self-signed certificates.
|
|
-- To test this we will verify that SSL is set to ON for all machines, and we will make
|
|
-- sure connections to workers use SSL by having it required in citus.conn_nodeinfo and
|
|
-- lastly we will inspect the ssl state for connections to the workers
|
|
-- ssl can only be enabled by default on installations of postgres 10 and above that are
|
|
-- OpenSSL-enabled.
