How to decrease the number of disk writes to a minimum of the supervisor?

Given the relatively short lifespan of the SD card that comes with the RPI, I am trying to decrease the number of IO writes to a minimum. In order to do that, I am using balena-engine stats to detect the read/writes of the different containers. Although the supervisor is not writing much, I would still be interested in understanding whether it is possible to limit how much it is writing to the fs. Any advice?

Thank you in advance!


The supervisor only writes to the fs if you change the configuration or make a new release. So the writing is pretty optimized already and I’m afraid cannot be optimized more at the moment.

Good to know. Thanks a lot!
