How To: Update runner runtime environment memory and CPU settings

Overview

Your builds may require more CPU and/or memory allocated in order to run.

Memory and CPU for runner runtime environments can be set per-pipeline in the workflow definition, under settings -> runtime.

To modify the default values for a runtime environment, you will need to use the Codefresh CLI to directly edit the runtime environment spec:

First export the runtime environment spec into a yaml file

codefresh get runtime-environments <runtme_env_name> -o yaml > runtime.yaml
Make modifications based on this yaml file. For build memory, these are the configurations to modify/add - replace “cpu” and “memory” values with the ones you want. requests is the amount of resources that are guaranteed per build, and limits is the maximum amount that can be allocated to a build.
```
 dockerDaemonScheduler:
   defaultDindResources:
     requests:
       cpu: 400m
       memory: 800Mi
     limits:
       cpu: 400m
       memory: 800Mi
```
Anything that’s explicitly listed in your runtime environment config will be used, otherwise the setting will be inherited from a parent runtime environment. So if these fields don’t already exist in your config, add them.
Once changes are complete, patch this config into your runtime environment definition on CF:

codefresh patch runtime-environment <runtme_env_name> -f runtime.yaml
