# Alibaba Cloud DNS (Alidns) CLI

## Goals

- Query and manage Alibaba Cloud DNS records via `aliyun-cli`.
- Quickly configure CNAME for Function Compute custom domains.

## When to Use

- When you need to add/update DNS records in Alibaba Cloud DNS.
- When you need CNAME setup for FC custom domains.

## Install aliyun-cli (without sudo)

```bash
curl -fsSL https://aliyuncli.alicdn.com/aliyun-cli-linux-latest-amd64.tgz -o /tmp/aliyun-cli.tgz
mkdir -p ~/.local/bin
 tar -xzf /tmp/aliyun-cli.tgz -C /tmp
mv /tmp/aliyun ~/.local/bin/aliyun
chmod +x ~/.local/bin/aliyun
```

## Configure Credentials

```bash
~/.local/bin/aliyun configure set \
  --profile default \
  --access-key-id <AK> \
  --access-key-secret <SK> \
  --region cn-hangzhou
```

Configure region as default; if best region is unclear, ask the user.

## Query DNS Records

Query subdomain records:

```bash
~/.local/bin/aliyun alidns DescribeSubDomainRecords \
  --SubDomain news.example.com
```

## Add CNAME Record

```bash
~/.local/bin/aliyun alidns AddDomainRecord \
  --DomainName example.com \
  --RR news \
  --Type CNAME \
  --Value <TARGET>
```

## FC Custom Domain CNAME Target

Custom domain should point to FC public CNAME:

```
<account_id>.<region_id>.fc.aliyuncs.com
```

Example (Hangzhou):

```
1629965279769872.cn-hangzhou.fc.aliyuncs.com
```

## Common Issues

- If apex CNAME is not supported, use subdomain like `www` or ALIAS/ANAME records.
- Create FC custom domain only after DNS propagation, otherwise `DomainNameNotResolved` may occur.
