kubectl set resources
Synopsis
Specify compute resource requirements (CPU, memory) for any resource that defines a pod template. If a pod is successfully scheduled, it is guaranteed the amount of resource requested, but may burst up to its specified limits.
For each compute resource, if a limit is specified and a request is omitted, the request will default to the limit.
Possible resources include (case insensitive): Use "kubectl api-resources" for a complete list of supported resources..
kubectl set resources (-f FILENAME | TYPE NAME) ([--limits=LIMITS & --requests=REQUESTS]
Examples
# Set a deployments nginx container cpu limits to "200m" and memory to "512Mi"
kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi
# Set the resource request and limits for all containers in nginx
kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi
# Remove the resource requests for resources on containers in nginx
kubectl set resources deployment nginx --limits=cpu=0,memory=0 --requests=cpu=0,memory=0
# Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml
