DEPRECATED

Resource management is built into Dokku as of 0.15.0. See here for more details.

dokku limit (beta)

App resource management plugin for dokku.

Currently supports setting limit's for memory and CPU per process type.

requirements

• dokku 0.9.x+
• docker 1.8.x

installation

# on 0.9.x+
sudo dokku plugin:install https://github.com/sarendsen/dokku-limit.git limit

On installation you might want to change the default limits. Or set limits for an app/proc pair before deploying/restarting. If no limits are yet set (after plugin installation or first time app deployment) or a new procces type is added to an app then the default limits will be used as template. See usage on changing the defaults.

Commands

limit (<app>)                                                   Pretty-print app resource limits
limit:set <app> <proc> [memory=VALUE cpu=VALUE] [--no-restart]  Set one or more limits for app/process pair
limit:defaults                                                  Pretty-print default resource limits
limit:set-defaults [memory=VALUE cpu=VALUE]                     Set default resource limits. These will be used for new apps/procs.

Resources

memory default: 1GB

The maximum amount of memory the process can use. It is written as with the unit describing the size dimension like "MB" or "GB". Examples: 512MB, 2GB, 10m

cpu default: 100

The maximum amount of CPU resources the process can use. example: "50"

This guarantees the process uses at most 50% of CPU every second.

Usage

# Set cpu to 50% and memory to 500 MB for process "web"
dokku limit:set my_app web cpu=50 memory=500m

# Show all resource limits
dokku limit

# Show resource limits for app "my_app"
dokku limit my_app

# Set cpu to 50% and memory to 500 MB as default
dokku limit:set-defaults cpu=50 memory=500m

# Show default resource limits
dokku limit:defaults
