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

容器中的主机名将是 Pod 的名称。您可以在 Python 中使用 os.unameos.environ 来查找:

import os

print(os.uname()[1])
print(os.environ['HOSTNAME'])
英文:

The hostname in the container will be the Pod name. You can find using os.uname or os.environ in Python:

import os

print(os.uname()[1])
print(os.environ['HOSTNAME'])

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())
