Created a job in kubernetes using post method using postman, now trying to patch the same job using patch method using postman and i am getting 400 bad request.
Headers for post: Content-type application/yaml
post method body:
---
apiVersion: batch/v1
kind: Job
metadata:
name: pi
labels:
app: dev
spec:
template:
spec:
containers:
- name: pi
image: perl
command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
restartPolicy: Never
backoffLimit: 4Headers for patch : Content-type application/strategic-merge-patch+json
patch request body:
{
"apiVersion": "batch/v1",
"kind": "Job",
"metadata": {
"name": "pi"
},
"spec": {
"template": {
"spec": {
"containers": [
{
"name": "pi",
"image": "perl",
"command": [
"perl",
"-Mbignum=bpi",
"-wle",
"print bpi(2000)"
]
}
],
"restartPolicy": "Never"
}
},
"backoffLimit": 5
}
}
Changed body please check the link. body of the patch request
Modification i did was changed backofflimit to 5. I was able to post and patch other resources like services and deployments but i am stuck at patching a job, I followed exactly same steps for others as well.
error i am getting error
With Content-Type as application/strategic-merge-patch+json
and with body
{ "spec": { "backoffLimit": 7 }}
I have recreated the request and it worked fine.
Things that went wrong first time is that even though "content-type" is mentioned in headers correctly as "application/strategic-merge-patch+json" postman is taking a wrong Content-type, so i deleted the request and recreated the patch request with same body and headers it worked perfectly.
With 'strategic-merge-patch+json' type you should use in the Request body just this json patch:
{"spec":{"backoffLimit": 7}}As your intent is to merge/replace existing object's value based on backoffLimit key.
Check documentation for example usage of strategic-merge-patch to update resources.
Update Please try yourself with curl:
kubectl proxycurl -k -v -XPATCH -H "Content-Type: application/strategic-merge-patch+json" --data '{"spe":{"backoffLimit": 9}}' http://localhost:8001/apis/batch/v1/namespaces/default/jobs/piOutput:
