We can achieve this with the help of adding the below sidecar section inside the halyard configuration file under the deploymentEnvironment.

  sidecars:

      spin-clouddriver-caching:

      - name: k8s-config-sync

        dockerImage: quay.io/konikris/k8s-decoder:git-k8s

        command: ["sh", "-c"]

        args: ["while true; do sh /tmp/script/k8config-sync.sh; sleep 60s; done"]

        configMapVolumeMounts:

        - configMapName: k8config-sync

          mountPath: /tmp/script

        mountPath: /opsmx
