SSD as cache and dockers


Recommended Posts

I just upgraded my cache from spinning disk to M.2 SSD.

 

I've now been monitoring the writes to the cache and see that a lot of dockers update their log files, which in my case are stored on the cache drive.  LetsEncrypt is a bad one as it updates its access.log file every 3-4 seconds.  This results in what appears to be a lot of writes to the disk.

 

Is this of concerns?  The writes are very small as the log file is just getting appended to.

 

How does everyone else handle log files from docker?  Just ignore it because is isn't a real issue.  Write to the /var/log area in the ram disk?  Maybe log rotate them to cache for backup?

 

Just curious,

david
