Anyone who get trouble using property additional container & volumeMounts

[Kim-menu]

Description: I just want sidecar container(additional container) with my task container. I put property like below

deployer.{myapp}.kubernetes.volumes=[{name: 'promtail-config', configMap: {name: promtail-config, items: [{key: promtail.yaml, path: promtail.yaml}]}}]
deployer.{myapp}.kubernetes.additional-containers=[{name: 'promtail',image: image-path-of-promtail, ports:[{protocol: TCP,containerPort: 8080}],args: ["-config.file=/home/conf/promtail.yaml"],volumeMounts: [{name: 'promtail-config', mountPath: '/home/conf'}]}]

of course, in my k8s cluster there is definitely promtail-config yaml object.

first, I put property for volumes second, I put property for additional container. Then, I describe info about volumeMounts

but I cannot launch task with this error log.

Message: Pod "test-task-9rq9ojo3k0" is invalid: spec.containers[1].volumeMounts[0].name: Not found: "promtail-config".

Did I understand k8s system badly?....

I searched about this property or example for it, Unfortunately, there is no information about additional container's volume in SCDF

Release versions: SCDF 2.10.2

Custom apps: Task

Is there anyone who had problem like my situation..?

@Kim-menu Thank you for reporting. While we investigate I would suggest consider using promtail service discovery then you won't need a sidecar for each pod.

@Kim-menu Did you create a ConfigMap resource named promtail-config?
