I have created kubernetes cluster on digitalocean. and I have deployed k6 as a job on kubernetes cluster.
apiVersion: batch/v1
kind: Job
metadata:
name: benchmark
spec:
template:
spec:
containers:
- name: benchmark
image: loadimpact/k6:0.29.0
command: ["k6", "run", "--vus", "2", "--duration", "5m", "--out", "json=./test.json", "/etc/k6-config/script.js"]
volumeMounts:
- name: config-volume
mountPath: /etc/k6-config
restartPolicy: Never
volumes:
- name: config-volume
configMap:
name: k6-config
this is how my k6-job.yaml file look like. After deploying it in kubernetes cluster I have checked the pods logs. it is showing permission denied error. level=error msg="open ./test.json: permission denied" how to solve this issue?
The k6 Docker image runs as an unprivileged user, but unfortunately the default work directory is set to /, so it has no permission to write there.
To work around this consider changing the JSON output path to /home/k6/out.json, i.e.:
command: ["k6", "run", "--vus", "2", "--duration", "5m", "--out", "json=/home/k6/test.json", "/etc/k6-config/script.js"]
I'm one of the maintainers on the team, so will propose a change to the Dockerfile to set the WORKDIR to /home/k6 to make the default behavior a bit more intuitive.
