[2026-03-24T09:59:07+08:00] couldn't execute POST against https://devops-build-new.aliyuncs.com/api/v2/runner/register: Post "https://devops-build-new.aliyuncs.com/api/v2/runner/register": x509: certificate signed by unknown authority
解决方法：
1. 导出证书链
openssl s_client -connect devops-build-new.aliyuncs.com:443 -servername devops-build-new.aliyuncs.com -showcerts </dev/null
2. 把“中间证书”复制出来，保存为：
/usr/local/share/ca-certificates/aliyun-devops.crt
3. 更新 CA
update-ca-certificates
4. 再 curl测试
curl -v https://devops-build-new.aliyuncs.com/api/v2/runner/register
