I've created an elasticsearch service to apply it like backend to jaeger tracing, using this guide, all over Kubernetes GCP cluster.
I have the elasticsearch service:
~/w/jaeger-elasticsearch ❯❯❯ kubectl get service elasticsearch
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
elasticsearch ClusterIP None <none> 9200/TCP,9300/TCP 8m
~/w/jaeger-elasticsearch ❯❯❯
And their respective pod called elasticsearch-0
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pods
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 37m
jaeger-agent-cnw9m 1/1 Running 0 2h
jaeger-agent-dl5n9 1/1 Running 0 2h
jaeger-agent-zzljk 1/1 Running 0 2h
jaeger-collector-9879cd76-fvpz4 1/1 Running 0 2h
jaeger-query-5584576487-dzqkd 1/1 Running 0 2h
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pod elasticsearch-0
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 38m
~/w/jaeger-elasticsearch ❯❯❯
I've enter to my pod configuration on GCP, and I can see that my elasticsearch-0 pod have limited resources:
apiVersion: v1
kind: Pod
metadata:
annotations:
kubernetes.io/limit-ranger: 'LimitRanger plugin set: cpu request for container
elasticsearch'
creationTimestamp: 2019-01-03T09:11:10Z
generateName: elasticsearch-
And then, I want to assign it specific CPU request and CPU limit according to the documentation, and then, I proceed to modufy the pod manifest, adding the following directives:
- cpu "2" in the args section:
args:
- -cpus
- "2"
And I am including a resources:requests field in the container resource, in order to specify a request of 0.5 CPU and I've include a resources:limits in order to specify a CPU limit of this way:
limits:
cpu: "1"
requests:
cpu: "0.5"
My complete pod manifest is this (See numerals 1,2,3,4 and 5 numerals commented with # symbol):

I've created an elasticsearch service to apply it like backend to jaeger tracing, using this guide, all over Kubernetes GCP cluster.
I have the elasticsearch service:
~/w/jaeger-elasticsearch ❯❯❯ kubectl get service elasticsearch
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
elasticsearch ClusterIP None <none> 9200/TCP,9300/TCP 8m
~/w/jaeger-elasticsearch ❯❯❯
And their respective pod called elasticsearch-0
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pods
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 37m
jaeger-agent-cnw9m 1/1 Running 0 2h
jaeger-agent-dl5n9 1/1 Running 0 2h
jaeger-agent-zzljk 1/1 Running 0 2h
jaeger-collector-9879cd76-fvpz4 1/1 Running 0 2h
jaeger-query-5584576487-dzqkd 1/1 Running 0 2h
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pod elasticsearch-0
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 38m
~/w/jaeger-elasticsearch ❯❯❯
I've enter to my pod configuration on GCP, and I can see that my elasticsearch-0 pod have limited resources:
apiVersion: v1
kind: Pod
metadata:
annotations:
kubernetes.io/limit-ranger: 'LimitRanger plugin set: cpu request for container
elasticsearch'
creationTimestamp: 2019-01-03T09:11:10Z
generateName: elasticsearch-
And then, I want to assign it specific CPU request and CPU limit according to the documentation, and then, I proceed to modufy the pod manifest, adding the following directives:
- cpu "2" in the args section:
args:
- -cpus
- "2"
And I am including a resources:requests field in the container resource, in order to specify a request of 0.5 CPU and I've include a resources:limits in order to specify a CPU limit of this way:
limits:
cpu: "1"
requests:
cpu: "0.5"
My complete pod manifest is this (See numerals 1,2,3,4 and 5 numerals commented with # symbol):
apiVersion: v1

How to can I modify my pod yaml file in order to assign it more resources and solve the kubernetes.io/limit-ranger: 'LimitRanger plugin set: cpu request for container elasticsearch' message?
elasticsearch kubernetes yaml google-kubernetes-engine asked Jan 3 at 11:44

I've created an elasticsearch service to apply it like backend to jaeger tracing, using this guide, all over Kubernetes GCP cluster.
I have the elasticsearch service:
~/w/jaeger-elasticsearch ❯❯❯ kubectl get service elasticsearch
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
elasticsearch ClusterIP None <none> 9200/TCP,9300/TCP 8m
~/w/jaeger-elasticsearch ❯❯❯
And their respective pod called elasticsearch-0
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pods
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 37m
jaeger-agent-cnw9m 1/1 Running 0 2h
jaeger-agent-dl5n9 1/1 Running 0 2h
jaeger-agent-zzljk 1/1 Running 0 2h
jaeger-collector-9879cd76-fvpz4 1/1 Running 0 2h
jaeger-query-5584576487-dzqkd 1/1 Running 0 2h
~/w/jaeger-elasticsearch ❯❯❯ kubectl get pod elasticsearch-0
NAME READY STATUS RESTARTS AGE
elasticsearch-0 1/1 Running 0 38m
~/w/jaeger-elasticsearch ❯❯❯
I've enter to my pod configuration on GCP, and I can see that my elasticsearch-0 pod have limited resources:
apiVersion: v1
kind: Pod
metadata:
annotations:
kubernetes.io/limit-ranger: 'LimitRanger plugin set: cpu request for container
elasticsearch'
creationTimestamp: 2019-01-03T09:11:10Z
generateName: elasticsearch-
And then, I want to assign it specific CPU request and CPU limit according to the documentation, and then, I proceed to modufy the pod manifest, adding the following directives:
- cpu "2" in the args section:
args:
- -cpus
- "2"
And I am including a resources:requests field in the container resource, in order to specify a request of 0.5 CPU and I've include a resources:limits in order to specify a CPU limit of this way:
limits:
cpu: "1"
requests:
cpu: "0.5"
My complete pod manifest is this (See numerals 1,2,3,4 and 5 numerals commented with # symbol):
apiVersion: v1
kind: Pod
metadata:
annotations:
