How to mount standard output logs of containers to a pod - Elastic Container Instance

This topic describes how to mount stdlog (standard output logs of containers) to an Elastic Container Instance pod. You must have root permissions to perform this operation.

Configuration example

Elastic Container Instance allows you to use the Container Storage Interface (CSI) plug-in to mount standard output logs of containers to an Elastic Container Instance pod. You must have root permissions to perform this operation. Configuration example:

Run the following command to create a YAML configuration file named stdlog_demo.yaml:

vim stdlog_demo.yaml

Copy the following template content into the stdlog_demo.yaml file:

apiVersion: v1
kind: Pod
metadata:
  name: test-stdlog-demo
spec:
  containers:
  - image: registry-vpc.cn-beijing.aliyuncs.com/eci_open/nginx:1.14.2
    name: test-container
    volumeMounts:
    - mountPath: /cache-test
      name: cache-volume
  volumes:
  - name: cache-volume
    csi:
      driver: stdlogplugin.csi.alibabacloud.com

Deploy the pod.
```
kubectl create -f stdlog_demo.yaml
```
Check the mount result.
View the file directories in the pod. The standard output logs of containers are mounted to the /cache-test directory of the pod. You can use the logs in the container.
```
kubectl get pod test-stdlog-demo
kubectl exec -it test-stdlog-demo bash
ls -l /cache-test
ls -l /cache-test/test-container
```
