Redisio cookbook

Chef Infra (archive)
1

I deployed the redisio cookbook and it seems to work like a charm. I did
have one question when it came to max memory. How would i specify 1
instance getting 60% memory; whereas the 2-3 instance receiving 30%? Would
this be done via role? Here is how I have my role setup for redis:

name "redis"
description "redis role applied to all redis servers."

run_list *%w[
recipe[redisio::install]
recipe[redisio::enable]
]

default_attributes({
'redisio' => {
'default_settings' => {'datadir' => '/etc/redis-db'},
'servers' => [{'port' => '6379', 'name' => "dev_redis"}, {'port' =>
'6380', 'name' => "uat_redis"}]
}
})

Here is the default attribute:

'maxmemory' => nil, - This allows the use of percentages, you must
append % to the number.

I guess where and how/where would I specify devredis receives X%?

Sorry I got it:

'servers' => [{'port' => '6379', 'name' => "dev_redis", 'maxmemory' =>
'60%'}, {'port' => '6380', 'name' => "uat_redis", 'maxmemory' => '60%'}]

You can put it in the individual instance hash:

'servers' => [{'port' => '6379', 'name' => "dev_redis"}, {'port' => '6380', 'name' => "uat_redis", 'maxmemory' => ’60%’}]

You should also explore the expiration algorithm options before setting max_memory or you’ll run into a lot of errors from Redis when max_memory is reached and there aren’t any keys to evict.

I believe the expiration alg defaults to volatile-lru, if that is what you
are referring to.
