Application Load Balancer (ALB)
Use this skill for end-to-end ALB operations via local Python scripts and OpenAPI-compatible workflows.
Validation
mkdir -p output/alicloud-network-alb
for f in skills/network/slb/alicloud-network-alb/scripts/*.py; do
python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/alicloud-network-alb/validate.txtPass criteria: command exits 0 and output/alicloud-network-alb/validate.txt is generated.
Output And Evidence
- Save all command outputs, request parameters, and API responses under
output/alicloud-network-alb/. - For change operations, keep before/after snapshots plus health-check results.
Prerequisites
pip install alibabacloud_alb20200616 alibabacloud_tea_openapi alibabacloud_credentialsCredential priority:
ALICLOUD_ACCESS_KEY_ID/ALICLOUD_ACCESS_KEY_SECRET- Optional STS token:
ALICLOUD_SECURITY_TOKEN - Shared config:
~/.alibabacloud/credentials
Workflow
- Confirm region, VPC context, target ALB resource IDs, and expected change window.
- Run inventory scripts first (
list_*,get_*) and save baseline outputs. - Apply one change at a time (listener/server-group/rule/lb lifecycle).
- Wait for async completion when needed (
scripts/wait_for_job.py). - Validate final state with health checks and state re-query.
