The logs of all NCP components can be redirected with this method. The applications need to be configured to log to stderr, which is enabled by default. The following procedure assumes that the syslog agent image is example/rsyslog.

Procedure

  1. Create the DaemonSet yaml file. For example,
        apiVersion: v1
        kind: ConfigMap
        metadata:
          name: rsyslog-config
          labels:
            version: v1
        data:
          nsx-ncp.conf: |
            module(load="imfile")
        
            ruleset(name="remote") {
              if $msg contains 'nsx-container' then
                action(type="omfwd"
                Protocol="tcp"
                Target="nsx.example.com"
                Port="514")
          
                stop
              }
          
              input(type="imfile"
                File="/var/log/containers/nsx-node-agent-*.log"
                Tag="nsx-node-agent"
                Ruleset="remote")
          
              input(type="imfile"
                File="/var/log/containers/nsx-ncp-*.log"
                Tag="nsx-ncp"
                Ruleset="remote")
          
              input(type="imfile"
                File="/var/log/syslog"
                Tag="nsx-cni"
                Ruleset="remote")
        ---
        # rsyslog DaemonSet
        apiVersion: extensions/v1beta1
        kind: DaemonSet
        metadata:
          name: rsyslog
          labels:
            component: rsyslog
            version: v1
        spec:
          template:
            metadata:
              labels:
              component: rsyslog
              version: v1
        spec:
          hostNetwork: true
          containers:
          - name: rsyslog
            image: example/rsyslog
            imagePullPolicy: IfNotPresent
            volumeMounts:
            - name: rsyslog-config-volume
              mountPath: /etc/rsyslog.d
            - name: log-volume
              mountPath: /var/log
            - name: container-volume
              mountPath: /var/lib/docker/containers
          volumes:
          - name: rsyslog-config-volume
            configMap:
            name: rsyslog-config
          - name: log-volume
            hostPath:
              path: /var/log
          - name: container-volume
            hostPath:
              path: /var/lib/docker/containers
  2. Create the DaemonSet.
    kubectl apply -f <daemonset yaml file>
