How do I resolve issue with:
"{"error":"sql: no rows in result set"}"

This is what I get in log:

root@vmdsc [ /home/vmdsc/logs ]# tail vmdsc.log -f

Ok, looks like I've been using Set-VMDSC instead of Add-VMDSC which corresponds to PUT and POST requests.
Set-VMDSC fails with PUT request since record does not yet exists.

Will there by any updates to VMDSC or will this be integrated into Aria Operations for vCenter?

This is great...hopefully one day it will be available directly in vSphere without additional appliance

+1 also for cpu/memory hot add enable/disable

Thank you

Our vCenter uses internally signed CAs. I've tried following the suggestions here in the comments, and a curl to the vCenter IP from the VMDSC appliance is now successful:

SSL certificate verify ok.

but the docker logs show:

panic: open /home/vmdsc/app/config/ca-cert.pem: permission denied

I confirmed the ca-cert.pem file exists and contains our intermediate and root certificates.

I figured it out -- permissions on the newly created ca-cert.pem file

was:
-rw-r----- 1 root root 3014 Jan 23 22:51 ca-cert.pem

now:
-rw-r----- 1 vmdsc root 3014 Jan 23 22:51 ca-cert.pem
