In Kubernetes, resource limits are used to define the maximum amount of resources (such as CPU and memory) that a container can use. These limits are specified in a container’s pod definition using the “resources” field.
The resources field contains two subfields: requests and limits. The requests field specifies the minimum amount of resources that must be available for the container to run. The limits field specifies the maximum amount of resources that the container is allowed to use.
For example, the following YAML code sets the CPU limit for a container to 1 core and the memory limit to 512 MB:
apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
containers:
- name: my-container
image: my-image
resources:
limits:
cpu: "1"
memory: "512Mi"
If a container exceeds its resource limit, Kubernetes will automatically kill and restart the container to prevent it from consuming too many resources and destabilizing the system.
