Redis service fails to start on Docker containers

[svenfuchs]

The Redis package that we currently install uses an init file like this:

root@089fae39196f:~# cat /etc/init/redis-server.conf
# redis-server - Redis Datastore Server
#
# Redis is a key value in memory persistent datastore

#start on (local-filesystems and runlevel [2345])
stop on runlevel [016]
respawn
expect fork
limit nofile 20000 65000
pre-start script
mkdir -p /var/run/redis
chown redis:redis /var/run/redis
end script
exec start-stop-daemon --start --chuid redis:redis --pidfile /var/run/redis/redis.pid --umask 007 --exec /usr/bin/redis-server -- /etc/redis/redis.conf

The limit nofile stanza fails on Docker containers (apparently ulimit can't be changed unless when run in -privileged model moby/moby#1900 (comment)).

Can this be removed?

[roidrage]

I think this could probably be removed. From what I can tell it sets ulimits on the open files?

[roidrage]

@svenfuchs is this still an issue?

[svenfuchs]

Yeah, I think this is still open.

[roidrage]

Can you look into fixing the cookbooks or our Redis configuration template?

[joshk]

making it configurable would be ideal

Closing this issue, as this seems to work as expected now.
