一种简单的方法是使用Downward API,将所需的信息作为环境变量传递,并从您的进程中读取这些变量。
示例:
env:
- name: MY_NODE_NAME
valueFrom:
fieldRef:
fieldPath: spec.nodeName
- name: MY_POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: MY_POD_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
可用字段:https://kubernetes.io/docs/concepts/workloads/pods/downward-api/
英文:
A simple way is to use the Downward API, pass the information you need as environment variables and read the variable from your process
Example:
env:
- name: MY_NODE_NAME
valueFrom:
fieldRef:
fieldPath: spec.nodeName
- name: MY_POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: MY_POD_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace

使用socket和其gethostname()功能。这将获取主机名,从而获取Python解释器运行的OpenShift/Kubernetes pod名称:
import socket
print(socket.gethostname())
英文:
Use socket and its gethostname() functionality. This will get the hostname and in turn the openshift/kubernetes pod name where the Python interpreter is running:
import socket
print(socket.gethostname())
