zeabur-domain-url（zeabur 域名 url）

Zeabur Domain URL Configuration

Always use npx zeabur@latest to invoke Zeabur CLI. Never use zeabur directly or any other installation method. If npx is not available, install Node.js first.

Symptom

• Redirects go to wrong URL (missing domain suffix, or has trailing slash)
• CORS errors due to URL mismatch
• ${ZEABUR_WEB_URL} has trailing slash causing path issues

System Variables

Solution

Expose URL from entry service to others:

- name: entry-service
  domainKey: PUBLIC_DOMAIN
  spec:
    env:
      APP_URL:
        default: https://${ZEABUR_WEB_DOMAIN}
        expose: true

- name: backend
  spec:
    env:
      WEB_URL:
        default: ${APP_URL}

Use https://${ZEABUR_WEB_DOMAIN} not ${ZEABUR_WEB_URL} to avoid trailing slash.

CLI Domain Management

List domains

npx zeabur@latest domain list --id <service-id> -i=false

Create a generated domain (*.zeabur.app)

Use -g to create a Zeabur-managed subdomain. With -g, --domain takes only the prefix (not the full domain):

npx zeabur@latest domain create --id <service-id> -g --domain myapp -y -i=false
# Suffix is auto-appended by backend based on region:
#   Default:           myapp.zeabur.app
#   Aliyun (China):    myapp.preview.aliyun-zeabur.cn
#   Tencent (China):   myapp.preview.tencent-zeabur.cn
#   Huawei (China):    myapp.preview.huawei-zeabur.cn
# China suffixes require completed identity verification on Zeabur.

Validation rules for generated domain prefix:

• At least 3 characters
• No dots allowed — only alphanumeric and hyphens
• Error DOMAIN_NAME_TOO_SHORT if less than 3 chars
• Error UNSUPPORTED_DOMAIN_NAME if prefix contains dots

Create a custom domain

Without -g, --domain takes a full domain name:

npx zeabur@latest domain create --id <service-id> --domain example.com -y -i=false

After creating a custom domain, use the zeabur-domain-dns skill to configure the required DNS records. For dedicated servers, find the IP with:

npx zeabur@latest server list -i=false
# Note the IP address of the server running your service

Then at your DNS provider:

Type: A
Name: <your subdomain or @>
Value: <server IP from above>

Do not guess DNS values. Always retrieve the actual server IP from server list output before configuring DNS.

Delete domain

npx zeabur@latest domain delete --id <service-id> --domain <domain> -y -i=false

Caution

• --domain is always required in non-interactive mode. Without it the CLI returns INVALID_DOMAIN_NAME.
• With -g, provide only the prefix (e.g., myapp), not the full myapp.zeabur.app.
• Without -g, provide the complete domain (e.g., example.com).
