OpenShift Quicktip: Limiting resource consumption for users

A. Resource limits

Resource limits allow you to set boundaries (max/min & default) for the compute resources a developer can define on pod/container level (see https://docs.openshift.com/enterprise/3.1/dev_guide/compute_resources.html).

1. Login to OpenShift with an admin user
2. Change to target project with

oc project <my-project>

1. Import limit range (see https://docs.openshift.com/enterprise/3.1/dev_guide/limits.html on what options are available)

oc create -f limit-range.json

1. Browse to OpenShift admin console, select the project and then “Settings”.

B. Quotas

A quota allows you to set hard limits on the overall resource consumption on project level. This is in particular useful to create a t-shirt size based accounting model (small, medium, large) for OpenShift. See also https://docs.openshift.com/enterprise/3.1/dev_guide/quota.html.

1. Login to OpenShift with an admin user
2. Change to target project with

oc project <my-project>

1. Create quota for project:

oc create -f resource-quota.json

1. Browse to OpenShift admin console, select the project and then “Settings”.
