wicked-kong produces lots of error messages

[florian-kiss]

When using a default redis instance created by wicked, I find lots of error messages produced inside the wicked-kong container, eg.:

[lua] init.lua:235: usage(): failed to connect to Redis: ERR Client sent AUTH, but no password is set, client: xxx, server: kong, request: "GET /ping-portal HTTP/1.1", host: "xxx"
[lua] handler.lua:94: failed to get usage: ERR Client sent AUTH, but no password is set, client: xxx, server: kong, request: "GET /ping-portal HTTP/1.1", host: "xxx"
[lua] init.lua:154: increment(): failed to auth Redis: ERR Client sent AUTH, but no password is set, context: ngx.timer, client: xxx, server: xxx

This repeats everytime kong pings redis, every 30s in my case.

Is there a way to get rid of these errors?
