一、需求描述

在本地签发自命名证书，用于K8S集群的Ingress的https配置。

前提条件：

  • 完成K8S集群搭建。
  • 完成证书制作机器的openssl服务安装。

二、自签名证书制作

2.1 脚本及配置文件准备

2.1.1 CA.sh脚本准备

注意事项：

  • openssl服务默认CA.sh地址为：/etc/pki/tls/misc/CA.sh，为证书拷贝方便基于原CA.sh进行复制对其原部分路径改写（改为读取同路径下的openssl.cnf文件）。
#!/bin/sh
#
# CA - wrapper around ca to make it easier to use ... basically ca requires
#      some setup stuff to be done before you can use it and this makes
#      things easier between now and when Eric is convinced to fix it :-)
#
# CA -newca ... will setup the right stuff
# CA -newreq ... will generate a certificate request
# CA -sign ... will sign the generated request and output
#
# At the end of that grab newreq.pem and newcert.pem (one has the key
# and the other the certificate) and cat them together and that is what
# you want/need ... I'll make even this a little cleaner later.
#
#
# 12-Jan-96 tjh    Added more things ... including CA -signcert which
#                  converts a certificate to a request and then signs it.
# 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
#                  environment variable so this can be driven from
#                  a script.
# 25-Jul-96 eay    Cleaned up filenames some more.
# 11-Jun-96 eay    Fixed a few filename missmatches.
# 03-May-96 eay    Modified to use 'ssleay cmd' instead of 'cmd'.

2.5 导出私钥

注意事项：

  • 避免出现：服务启动提示输入：PEM pass phrase情况，故将私钥导出。
[root@k8s-master openssl-CA]# openssl rsa -in newkey.pem -out nginx.local.key
Enter pass phrase for newkey.pem:
writing RSA key

2.6 导出证书

[root@k8s-master openssl-CA]# openssl x509 -in newcert.pem  -out nginx.local.pem
[root@k8s-master openssl-CA]#

2.7 导出Windows平台能安装的根证书

[root@k8s-master openssl-CA]# cd demoCA/
[root@k8s-master demoCA]# openssl x509 -in cacert.pem -out cacert.crt
[root@k8s-master demoCA]# cd ..
[root@k8s-master openssl-CA]#

2.8 导出Linux平台能安装的根证书

[root@k8s-master openssl-CA]# openssl x509 -in demoCA/cacert.pem -out ca.pem
[root@k8s-master openssl-CA]#

查看根证书ca.pem
在这里插入图片描述

切换root权限，将根证书内容追加到受信任根证书列表配置文件

[root@k8s-master openssl-CA]# 
[root@k8s-master openssl-CA]# cat ca.pem >> /etc/pki/tls/certs/ca-bundle.crt

三、自签名证书写入secret

kubectl create secret tls nginx.local --key nginx.local.key  --cert nginx.local.pem

四、Deployment具体配置
