管理根CA
使用
docker swarm ca [OPTIONS]
备选方案
名字，简写 | 默认 | 描述 |
|---|---|---|
--ca-cert | 用于新集群的PEM格式的根CA证书的路径 | |
--ca-key | 用于新集群的PEM格式化根CA密钥的路径 | |
--cert-expiry | 2160h0m0s | 节点证书的有效期（ns | us | ms | s | m | h） |
--detach, -d | 假 | 立即退出，而不是等待根旋转收敛 |
--external-ca | 一个或多个证书签名端点的规格 | |
--quiet, -q | 假 | 抑制进度输出 |
--rotate | 假 | 旋转丛集CA - 如果未提供证书或密钥，则会生成新的证书或密钥 |

扩展描述
查看或旋转当前群集CA证书。此命令必须针对管理器节点。
实例
运行docker swarm ca命令，没有任何选项可以查看PEM格式的当前根CA证书。

传递该--rotate标志（以及可选的a --ca-cert，连同一个--ca-key或--external-ca参数标志），以便旋转当前群根CA.
$ docker swarm ca --rotate desired root digest: sha256:05da740cf2577a25224c53019e2cce99bcc5ba09664ad6bb2a9425d9ebd1b53e rotated TLS certificates: [=========================> ] 1/2 nodes rotated CA certificates: [> ] 0/2 nodes
一旦旋转os完成（所有进度条完成），将打印当前的CA证书：

--rotate
如果一个或多个群集管理器已被破坏，则建议使用根CA旋转，以便这些管理器无法再连接到群集中的任何其他节点或受其信任。
或者，可以使用根CA旋转来将群集CA控制权授予外部CA，或从外部CA获取控制权。
--rotate标志不需要任何参数进行轮换，但您可以选择指定证书和密钥，或者证书和外部CA URL，并且将使用这些参数代替自动生成的证书/密钥对。
由于根CA密钥应该保密，如果提供，通过CLI或API查看群集任何信息时都不可见。
直到所有注册节点都旋转了他们的TLS证书后，根CA轮换才能完成。如果旋转没有在合理的时间内完成，请尝试运行docker node ls --format {{.ID}} {{.Hostname}} {{.Status}} {{.TLSStatus}}以查看是否有节点关闭或无法旋转TLS证书。
--detach
启动根CA旋转，但不要等待旋转的完成或显示旋转的进度。
