I have created a self-signed ignition TLS certificate and followed the instructions in the following document to reuse the ignition certificate for MQTT.
https://docs.chariot.io/display/CLD80/Configuring+Secure+MQTT+Communication
There is a specific part for when using self-signed certificates where it says that I need to identify the certificate chain so as to upload and direct the certificate to the MQTT engine directly. It does not explain how to find this information from Ignition? The only file I can get from Ignition related to the TLS certificate is the CSR file which is not the right thing.
Could anyone please direct me as to where I can get this certificate chain so I can do the last step? Thanks.
