How to Write Python Scripts to Take Eureka Services Offline and Online

Eureka Offline Script

Python script that takes a specific Eureka service instance offline by setting its status to OUT_OF_SERVICE via a PUT request.

import sys
import requests

APP_NAME = sys.argv[1]
INSTANCE_ID = sys.argv[2]
eureka_url = "https://eureka_url/eureka/apps"
instance_out_of_service_url = f"{eureka_url}/{APP_NAME}/{INSTANCE_ID}/status?value=OUT_OF_SERVICE"
response = requests.put(instance_out_of_service_url)
print(response.status_code)
if response.status_code == 200:
    print('服务实例成功下线')
else:
    print('服务实例下线失败，状态码：', response.status_code)

Eureka Online Script

Python script that brings a Eureka service instance back online by setting its status to UP via a PUT request.

import sys
import requests

APP_NAME = sys.argv[1]
INSTANCE_ID = sys.argv[2]
eureka_url = "https://eureka_url/eureka/apps"
instance_up_url = f"{eureka_url}/{APP_NAME}/{INSTANCE_ID}/status?value=UP"
response = requests.put(instance_up_url)
print(response.status_code)
