Prevent redis DB size runaway about mailserver HOT 8 CLOSED

@1n5aN1aC I have a cron job for that...

0 3 * * * docker exec redis redis-cli BGREWRITEAOF

from mailserver.

Since Redis 2.4 the AOF rewrite is automatically triggered by Redis, however the BGREWRITEAOF command can be used to trigger a rewrite at any time.

If you're using the AOF with Redis 2.2 you'll need to run BGREWRITEAOF from time to time. Redis 2.4 is able to trigger log rewriting automatically

The documentation says that it is not necessary because BGREWRITEAOF is triggered automatically to avoid that precisely. I missed something ?

On my personal serv, aof file is only 24MB size, and 87MB on another and bigger mail server, after 2 years.

My understanding from the documentation is that it is only 'called automatically' because the directives I mentioned are in the default config file. My understanding was that the default config file is not being used. (as no config file is being used)

That being said, it's possible it grew so massively from something wrong on my server years ago. Today my db is 67MB. So obviously it's not growing at any serious rate right now.

I noticed the same. Mine was around 500MB and running redis-cli BGREWRITEAOF made it 50MB.

That makes sense. I let you make a pull request if you want.

Is there a reason this isn't left to the user when setting up the redis container? Maybe specifying that foo=bar should be in the redis config is enough?

This makes only sense, if you change the config file.
Redis without any config:

127.0.0.1:6379> CONFIG GET auto-aof-rewrite-percentage
1) "auto-aof-rewrite-percentage"
2) "100"
127.0.0.1:6379> CONFIG GET auto-aof-rewrite-min-size
1) "auto-aof-rewrite-min-size"
2) "67108864"

Tested with the docker-compose.sample.yml
