Description Hemant Kumar 2019-04-30 19:15:40 UTC

I don't know if it is because of bad packaging or something else but prometheus does not log version information with OCP images we are building for 4.1 (in CI):

Comment 1 Paul Gier 2019-05-01 03:49:02 UTC

I believe this is related to the switch to go 1.11 and the use of go modules.
