[kubernetes-users] adding docker run --log-opt arguments to deployments

[baldey]

Hi all

We are trying to add docker logging options to our kubernetes deployments for 
log rolling e.g --log-opt max-size=10m

For example if we ran something like this directly using docker

docker run -it --log-opt max-size=10m --log-opt max-file=2 image-name

We can use docker inspect to see those options added to the LogConfig e.g

"LogConfig": {
                "Type": "json-file",
                "Config": {
                    "max-file": "2",
                    "max-size": "10m"
                }
            },



Here is what we have defined in our deployment:

containers:
      - image: ourlocalrepo/deployments/our_pod:latest
        command:
        - java
        - -Djava.security.egd=file:/dev/./urandom
        - -Dlog4j.configurationFile=/etc/logs-config/log4j2.xml
        - -Xms128m
        - -Xmx256m
        - -jar 
       env:
          - name: POD_NAME
            valueFrom:
              fieldRef:
                fieldPath: metadata.name
          - name: POD_NAMESPACE
            valueFrom:
              fieldRef:
                fieldPath: metadata.namespace
imagePullPolicy: Always
        name: "our_pod"
        ports:
        - containerPort: 80
          protocol: TCP
        args:
        - "--log-opt max-size=10m"
        - "--log-opt max-file=2"

But when this deployment is run and the pod comes up on a node i can use docker 
inspect and see that these args are added to Cmd:

"Cmd": [
                "--log-opt max-size=10m",
                "--log-opt max-file=2"
            ],

Instead of the LogConfig section as they should be - it still looks like this :

"LogConfig": {
                "Type": "json-file",
                "Config": {}
            },

Can anyone point me the right direction to get the kubernetes deployment to add 
these log options?

thanks!!
