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
- 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
- Create the DaemonSet.
