我正在调试主机和 Docker 容器之间的 TLS 连接问题。我的 Docker 容器有一个服务器证书:

因此,如果是s_client
主机和容器之间的连接,则会出现错误,unsupported certificate purpose
而如果是容器内的连接,则正常工作。
$ openssl verify
在两种环境下均可正常工作。
主持人:
$ openssl verify -CAfile ./ca.crt server.crt
server.crt: OK
码头工人:
# openssl verify -CAfile ./ca.crt server.crt
server.crt: OK
OpenSSL 版本主持人机器:OpenSSL 1.1.1d 10 Sep 2019
OpenSSL 版本码头工人:OpenSSL 1.0.2g 1 Mar 2016
你能帮助我这里可能存在什么问题吗?
答案1
看起来类似于此错误报告:Nginx #1760。
您的 CA 密钥报告“任何扩展密钥使用情况”。自 OpenSSL 1.1.0 起,它受支持。这就是不同版本行为不同的原因。要修复此问题,我认为您需要更新 OpenSSL。
