亚马逊服务中的OpenSearch服务软件更新

发送start-service-software-updateAmazon CLI请求以启动服务软件更新。此示例立即将更新添加到队列中：

aws opensearch start-service-software-update \
  --domain-name my-domain \
  --schedule-at "NOW"

响应:

{
    "ServiceSoftwareOptions": {
        "CurrentVersion": "R20220928-P1",
        "NewVersion": "R20220928-P2",
        "UpdateAvailable": true,
        "Cancellable": true,
        "UpdateStatus": "PENDING_UPDATE",
        "Description": "",
        "AutomatedUpdateDate": "1969-12-31T16:00:00-08:00",
        "OptionalDeployment": true
    }
}

如果请求失败并显示为BaseException，则表示由于容量原因，您指定的时间不可用，您必须指定不同的时间。OpenSearch服务在响应中提供其他可用时段建议。

此示例 Python 脚本使用 Amazon SDK for Python (Boto3) 中的 describe_domain 和 start_service_software_update 方法来检查域是否符合服务软件更新的条件，如果是，则启动更新。您必须为 domain_name 提供一个值。

import boto3
from botocore.config import Config
import time

# Build the client using the default credential configuration.
# You can use the CLI and run 'aws configure' to set access key, secret
# key, and default region.

my_config = Config(
    # Optionally lets you specify a Region other than your default.
    region_name='us-east-1'
)

domain_name = ''  # The name of the domain to check and update

client = boto3.client('opensearch', config=my_config)


def getUpdateStatus(client):
    """Determines whether the domain is eligible for an update"""
    response = client.describe_domain(
        DomainName=domain_name
    )
    sso = response['DomainStatus']['ServiceSoftwareOptions']
    if sso['UpdateStatus'] == 'ELIGIBLE':
        print('Domain [' + domain_name + '] is eligible for a service software update from version ' +
              sso['CurrentVersion'] + ' to version ' + sso['NewVersion'])
        updateDomain(client)
    else:
        print('Domain is not eligible for an update at this time.')


def updateDomain(client):
    """Starts a service software update for the eligible domain"""
    response = client.start_service_software_update(
        DomainName=domain_name
    )
    print('Updating domain [' + domain_name + '] to version ' +
          response['ServiceSoftwareOptions']['NewVersion'] + '...')
    waitForUpdate(client)


def waitForUpdate(client):
    """Waits for the domain to finish updating"""
    response = client.describe_domain(
        DomainName=domain_name
    )
    status = response['DomainStatus']['ServiceSoftwareOptions']['UpdateStatus']
    if status == 'PENDING_UPDATE' or status == 'IN_PROGRESS':
        time.sleep(30)
        waitForUpdate(client)
    elif status == 'COMPLETED':
        print('Domain [' + domain_name +
              '] successfully updated to the latest software version')
    else:
        print('Domain is not currently being updated.')

def main():
    getUpdateStatus(client)

您可以在 “非高峰时段” 选项卡上查看预定操作并随时重新安排。请参阅查看预设操作。

要使用在即将到来的非高峰时段安排更新Amazon CLI，请发送StartServiceSoftwareUpdate请求并指定OFF_PEAK_WINDOW--schedule-at参数：

aws opensearch start-service-software-update \
  --domain-name my-domain \
  --schedule-at "OFF_PEAK_WINDOW"
