Created a pod using yaml
and once pod is created I am running kubectl exec
to run my gatling perf test code
kubectl exec gradlecommandfromcommandline -- ./gradlew gatlingRun-
simulations.RuntimeParameters -DUSERS=500 -DRAMP_DURATION=5 -DDURATION=30
but this is ending at kubectl console with below message :-
command terminated with exit code 137
On Investigation its found that pod is changing status from running to completed stage.
How do i increase life span of a pod so that it waits for my command to get executed.Here is pod yaml
apiVersion: v1
kind: Pod
metadata:
name: gradlecommandfromcommandline
labels:
purpose: gradlecommandfromcommandline
spec:
containers:
- name: gradlecommandfromcommandline
image: tarunkumard/tarungatlingscript:v1.0
workingDir: /opt/gatling-fundamentals/
command: ["./gradlew"]
args: ["gatlingRun-simulations.RuntimeParameters", "-DUSERS=500", "-
DRAMP_DURATION=5", "-DDURATION=30"]
restartPolicy: OnFailure
Here is yaml file to make pod running always apiVersion: v1
kind: Pod
metadata:
name: gradlecommandfromcommandline
labels:
purpose: gradlecommandfromcommandline
spec:
volumes:
- name: docker-sock
hostPath:
path: /home/vagrant/k8s/pods/gatling/user-files/simulations # A file or
directory location on the node that you want to mount into the Pod
# command: [ "git clone https://github.com/TarunKDas2k18/PerfGatl.git" ]
containers:
- name: gradlecommandfromcommandline
image: tarunkumard/tarungatlingscript:v1.0
workingDir: /opt/gatling-fundamentals/
command: ["./gradlew"]
args: ["gatlingRun-simulations.RuntimeParameters", "-DUSERS=500", "-
DRAMP_DURATION=5", "-DDURATION=30"]
- name: gatlingperftool
image: tarunkumard/gatling:FirstScript # Run the ubuntu 16.04
command: [ "/bin/bash", "-c", "--" ] # You need to run some task inside a
container to keep it running
args: [ "while true; do sleep 10; done;" ] # Our simple program just sleeps inside
an infinite loop
volumeMounts:
- mountPath: /opt/gatling/user-files/simulations # The mount path within the
container
name: docker-sock # Name must match the hostPath volume name
ports:
- containerPort: 80
