# Application Load Balancer (ALB)

Use this skill for end-to-end ALB operations via local Python scripts and OpenAPI-compatible workflows.

## Validation

```bash
mkdir -p output/aliyun-alb-manage
for f in skills/network/slb/aliyun-alb-manage/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/aliyun-alb-manage/validate.txt
```

Pass criteria: command exits 0 and `output/aliyun-alb-manage/validate.txt` is generated.

## Output And Evidence

- Save all command outputs, request parameters, and API responses under `output/aliyun-alb-manage/`.
- For change operations, keep before/after snapshots plus health-check results.

## Prerequisites

```bash
pip install alibabacloud_alb20200616 alibabacloud_tea_openapi alibabacloud_credentials
```

Credential priority:

1. `ALIBABACLOUD_ACCESS_KEY_ID` / `ALIBABACLOUD_ACCESS_KEY_SECRET`
2. Optional STS token: `ALIBABACLOUD_SECURITY_TOKEN`
3. Shared config: `~/.alibabacloud/credentials`

## Workflow

1. Confirm region, VPC context, target ALB resource IDs, and expected change window.
2. Run inventory scripts first (`list_*`, `get_*`) and save baseline outputs.
3. Apply one change at a time (listener/server-group/rule/lb lifecycle).
4. Wait for async completion when needed (`scripts/wait_for_job.py`).
5. Validate final state with health checks and state re-query.

## Top task playbooks

### 1) Read-only inventory and quick diagnosis

```bash
python3 scripts/list_instances.py --region cn-hangzhou --json --output output/aliyun-alb-manage/instances.json
python3 scripts/list_server_groups.py --region cn-hangzhou --json --output output/aliyun-alb-manage/server-groups.json
python3 scripts/list_acls.py --region cn-hangzhou --json --output output/aliyun-alb-manage/acls.json
```

### 2) Inspect one ALB and listener details

```bash
python3 scripts/get_instance_status.py --region cn-hangzhou --lb-id alb-xxx --view detail --output output/aliyun-alb-manage/lb-detail.json
python3 scripts/list_listeners.py --region cn-hangzhou --lb-id alb-xxx --json --output output/aliyun-alb-manage/listeners.json
python3 scripts/get_listener_attribute.py --region cn-hangzhou --listener-id lsn-xxx --output output/aliyun-alb-manage/listener-attr.json
```

### 3) Validate traffic path health

```bash
python3 scripts/check_health_status.py --region cn-hangzhou --listener-id lsn-xxx --output output/aliyun-alb-manage/health.json
python3 scripts/list_server_group_servers.py --region cn-hangzhou --server-group-id sgp-xxx --output output/aliyun-alb-manage/server-group-members.json
```

### 4) Controlled change flow (example: update listener)

```bash
python3 scripts/update_listener.py --region cn-hangzhou --listener-id lsn-xxx --request-timeout 120 --output output/aliyun-alb-manage/update-listener.json
python3 scripts/check_health_status.py --region cn-hangzhou --listener-id lsn-xxx --output output/aliyun-alb-manage/health-after-update.json
```

### 5) Resource lifecycle operations

- ALB lifecycle: `create_load_balancer.py`, `delete_load_balancer.py`, `deletion_protection.py`
- Listener lifecycle: `create_listener.py`, `start_listener.py`, `stop_listener.py`, `delete_listener.py`
- Server-group lifecycle: `create_server_group.py`, `add_servers.py`, `remove_servers.py`, `delete_server_group.py`
- Rule lifecycle: `create_rule.py`, `update_rule.py`, `delete_rule.py`
