Maelezo zaidi kuhusu EventBridge Scheduler katika:

AWS - EventBridge Scheduler Enum

iam:PassRole, (scheduler:CreateSchedule | scheduler:UpdateSchedule)

Mshambuliaji mwenye ruhusa hizo ataweza kuunda|kupdate ratiba na kutumia ruhusa za jukumu la ratiba lililounganishwa nayo kufanya kitendo chochote

Kwa mfano, wanaweza kuunda ratiba ili kuitisha kazi ya Lambda ambayo ni kitendo kilichopangwa:

aws scheduler create-schedule \
--name MyLambdaSchedule \
--schedule-expression "rate(5 minutes)" \
--flexible-time-window "Mode=OFF" \
--target '{
"Arn": "arn:aws:lambda:<region>:<account-id>:function:<LambdaFunctionName>",
"RoleArn": "arn:aws:iam::<account-id>:role/<RoleName>"
}'

Katika kuongeza hatua za huduma zilizotengenezwa, unaweza kutumia universal targets katika EventBridge Scheduler kuanzisha anuwai ya operesheni za API kwa huduma nyingi za AWS. Universal targets hutoa kubadilika kuanzisha karibu API yoyote. Mfano mmoja unaweza kuwa kutumia universal targets kuongeza "AdminAccessPolicy", kwa kutumia jukumu ambalo lina sera ya "putRolePolicy":

aws scheduler create-schedule \
--name GrantAdminToTargetRoleSchedule \
--schedule-expression "rate(5 minutes)" \
--flexible-time-window "Mode=OFF" \
--target '{
"Arn": "arn:aws:scheduler:::aws-sdk:iam:putRolePolicy",
"RoleArn": "arn:aws:iam::<account-id>:role/RoleWithPutPolicy",
"Input": "{\"RoleName\": \"TargetRole\", \"PolicyName\": \"AdminAccessPolicy\", \"PolicyDocument\": \"{\\\"Version\\\": \\\"2012-10-17\\\", \\\"Statement\\\": [{\\\"Effect\\\": \\\"Allow\\\", \\\"Action\\\": \\\"*\\\", \\\"Resource\\\": \\\"*\\\"}]}\"}"
}'
