Error response from daemon: missing client certificate

docker push 镜像报错：

Error response from daemon: missing client certificate www.test.com.cert for key www.test.com.key

需要将 证书文件 放在/etc/docker/certs.d/www.test.com/目录下。

ls /etc/docker/certs.d/www.test.com/
ca.crt www.test.com.key www.test.com.cert

如果你使用的是阿里云或其他厂商的免费的SSL证书，只需要下载根证书，后重名为yourdomain.cert。

使用openssl 将pem文件转成crt再转成cert。

openssl x509 -inform PEM -in yourdomain.pem -out yourdomain.crt

openssl x509 -inform PEM -in yourdomain.com.crt -out yourdomain.com.cert

certificate signed by unknown authority

docker pull 报错：

Error response from daemon: Get https://xxx/v2/: x509: certificate signed by unknown authority
