I need apply a oc patch to the following deploy, changing de value of "image". But I can´t do that, caused by an error:

I´m triying the following:
root@oc-jump-pod:/# oc patch deploy push-engine --type='json' -p='{"spec":{"template":{"metadata":{"spec":{"containers":{"image":"registry.sdi.
dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1"}}}}}}'
Error from server (BadRequest): json: cannot unmarshal object into Go value of type jsonpatch.Patch
and this to get the value
root@oc-jump-pod:/# oc get deploy push-engine -o=jsonpath='{..image}'
registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test-java:0.0.2
I need do that, to change the tag of the image from 0.0.2 to 0.0.1 (or others). Probably I don´t understand oc patch yet, actually I do the change manually on the oc console. But this method, is rude and not follow the CI/CD.
The correct JSON Patch document for your Deployment
may look like this:
[
{
"op": "replace",
"path": "/spec/template/spec/containers/0/image",
"value": "registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1"
}
]
Your example is not going to work as it doesn't reflect the structure of your original yaml
file. Note that it contains arrays [...]
and you treated it as if it contained only maps {...}
.
Your final oc patch
command may look as follows:
oc patch deploy push-engine --type='json' -p '[{ "op": "replace", "path": "/spec/template/spec/containers/0/image", "value": "registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1" }]'
