Configuring Fluentd Sidecar Container in Kubernetes
You can use a Fluentd sidecar container running alongside the API Gateway container within a pod to perform log aggregation.
The configuration for setting up Fluentd as a sidecar container is as follows:
containers:
- name: apigateway
...
volumeMounts:
- name: log_volume
mountPath: path_to_log_files_in_api_gateway_container
- name: fluentd
...
volumeMounts:
- name: fluentd_config_volume
mountPath: path_to_configuration_file_in_fluentd_container
subPath: fluentd_configuration_file_name
- name: log_volume
mountPath: path_to_log_files_in_fluentd_container
...
volumes:
- name: fluentd_config_volume
hostPath:
path: path_to_fluentd_configuration_file
type: Directory
- name: log_volume
emptyDir: {}
Replace the following placeholders with the actual values:
Volume names. Make sure the volume names are correctly referenced. Replace
fluentd_config_volume and
log_volume with the actual names you want to use.
Paths. Verify that the paths specified in
mountPath and
hostPath are accurate and correspond to the directories in your containers and on the host.
SubPath. Ensure that
subPath points to the correct configuration file in the Fluentd container.
An example configuration for setting up Fluentd as a sidecar container is as follows:
containers:
- name: apigateway
...
volumeMounts:
- name: apigwlog-volume
mountPath: /opt/softwareag/IntegrationServer/logs
- name: apigwlog-volume
mountPath: /opt/softwareag/apigatewayui/logs
- name: fluentd
...
volumeMounts:
- name: config-volume
mountPath: /fluentd/etc/fluent.conf
subPath: fluentd.conf
- name: apigwlog-volume
mountPath: /fluentd/apigateway_source/logs
volumes:
- name: config-volume
hostPath:
path: /mnt/fluentd/config
type: Directory
- name: apigwlog-volume
emptyDir: {}
