Add filebeat.yml to resources (e.g. oom/kubernetes/<component>/resources/config/log/filebeat/filebeat.yml)
A sample filebeat.yml can be found in the log demon node project:
https://gerrit.onap.org/r/gitweb?p=logging-analytics.git;a=tree;f=reference/logging-kubernetes/logdemonode/charts/logdemonode/resources/config/log/filebeat;h=abf4f0a84ae7a15ed99fc4776727e4333948b583;hb=d882270162d56c55da339af8fb9384e1bdc0160dAdd Filebeat container to deployment.yaml:
Code Block # Filebeat sidecar container - name: {{ include "common.name" . }}-filebeat-onap image: "{{ .Values.global.loggingRepository }}/{{ .Values.global.loggingImage }}" imagePullPolicy: {{ .Values.global.pullPolicy | default .Values.pullPolicy }} volumeMounts: - name: {{ include "common.fullname" . }}-filebeat-conf mountPath: /usr/share/filebeat/filebeat.yml subPath: filebeat.yml - name: {{ include "common.fullname" . }}-data-filebeat mountPath: /usr/share/filebeat/data - name: {{ include "common.fullname" . }}-logs mountPath: /var/log/onap
Here the image and pull policy and based on global values.
The {{ include "common.fullname" . }}-filebeat-conf volume mount is used to share the filebeat.yml config resource.The {{ include "common.fullname" . }}-logs volume mount is used to share the application logs for other containers in the pod
The {{ include "common.fullname" . }}-data-filebeat volume mount is used to share filebeat logs
Add configmap to component to reference the filebeat.yml file that will be deployed to container (e.g. kubernetes/<component>/templates/configmap.yaml:
Code Block apiVersion: v1 kind: ConfigMap metadata: name: {{ .Release.Name }}-<component>-filebeat-configmap namespace: {{ include "common.namespace" . }} data: {{ tpl (.Files.Glob "resources/config/log/filebeat/filebeat.yml").AsConfig . | indent 2 }}
Replace <component> with the component name
Add filebeat repo and image specification to values.yaml and config of service name and port:
In file, oom/kubernetes/<component>/values.yaml, addCode Block global: loggingRepository: docker.elastic.co loggingImage: beats/filebeat:5.5.0 # application configuration config: logstashServiceName: log-ls logstashPort: 5044
Add logback.xml file to microservice resources:
kubernetes/<component>/charts/<microservice>/resources/config/logback.xmlA sample logback can be found here:
https://gerrit.onap.org/r/gitweb?p=logging-analytics.git;a=tree;f=reference/logging-kubernetes/logdemonode/charts/logdemonode/resources/config;hb=d882270162d56c55da339af8fb9384e1bdc0160dCreate configmap for microservice to share logback.xml with application container:
Create/modify file, oom/kubernetes/pomba/charts/pomba-aaictxbuilder/templates/configmap.yaml
Code Block apiVersion: v1 kind: ConfigMap metadata: name: {{ include "common.fullname" . }}-log namespace: {{ include "common.namespace" . }} data: {{ tpl (.Files.Glob "resources/config/logback.xml").AsConfig . | indent 2 }}
Add volume mounts to microservice deployment.yaml to share logs and reference logback.xml:
Modify container section of file, oom/kubernetes/<component>/charts/<microservice>/templates/deployment.yaml
Code Block volumeMounts: - name: {{ include "common.fullname" . }}-logs mountPath: /var/log/onap - mountPath: /opt/ajsc/etc/config/logback.xml name: {{ include "common.fullname" . }}-log-conf subPath: logback.xml
Note volumeMounts section may already exist. If so, just add new content to the existing section
Add volumes specification to microservice deployment.yaml to 1) share logback.xml via configmap, 2) share filebeat.yml via configmap, 3) share filebeat data via emptyDir 4) share application log data via emptyDir
Add/modify volumes section of file, oom/kubernetes/<component>/charts/<microservice>/templates/deployment.yamlCode Block volumes: - name: {{ include "common.fullname" . }}-log-conf configMap: name: {{ include "common.fullname" . }}-log - name: {{ include "common.fullname" . }}-filebeat-conf configMap: name: {{ .Release.Name }}-<component>-filebeat-configmap - name: {{ include "common.fullname" . }}-data-filebeat emptyDir: {} - name: {{ include "common.fullname" . }}-logs emptyDir: {}
Replace <component> with the component name
If volumes section already exists, add content to existing section
