图表，海图 ①k8s对系统要求 linux内核在3.10及以上，服务器规格2核cpu，2G内存及以上，可以装在虚拟机 里，也可以装在实体机上 ②规划主机名及ip k8s的服务器使用固定ip地址，配置主机名，要求能解析相应的主机名（master 结点）到对应的ip地址，可以使用内网集群的dns服务器或写入/etc/hosts文件 里。如： 主机名 ip地址 k8s-master1 accept' # firewall-cmd --run�me-to-permanent # firewall-cmd --list-all ★如果有硬件交换机做ACL或基于云的安全组做访问控制，则可关闭服务器上的 防火墙软件 ⑨加载ipvs模块 # cat > /etc/modules-load.d/k8s-ipvs.conf <服务器上，再docker load导入；或者使 用内部registry仓库（内部registry镜像仓库里要有以上7个镜像） ★直接使用命令行方式初始化集群 （以下是非HA模式的master初始

gitlab是一个基于git实现的在线代码仓库软件，提供web可视化管理界面，通常 用于企业团队内部协作开发 ★安装gitlab-ce 部署gitlab-ce要求服务器内存>=4GB，本例使用操作系统为 Rocky Linux 8.8， gitlab-ce版本16.5.0 ★首先gitlab服务器要安装ntp时间服务 # yum install chrony -y # systemctl enable chronyd start chronyd # vi /etc/chrony.conf server 10.99.1.1 iburst prefer #配置集群可访问的ntp服务器 # �medatectl set-�mezone Asia/Shanghai #设置时区 # systemctl restart chronyd # chronyc sources branch 'main' set up to track 'rmtRepo/main'. ★添加用户的ssh密钥 由用户登录gitlab界面，自行添加ssh key 首先在linux服务器上生成用户的ssh密钥对文件 # ssh-keygen -t rsa -b 2048 -C "cof@cof-lee.com" -P "" -f cof-sshkey #直接生成key文件及公钥

direction our life takes; but alas, this perception has more to do with our desires – with how we want to view ourselves – than with reality. “A second main lesson lesson is that althrough irrationality is perspective as we do.” o “Ownership is not limited to material things. It can also apply to points of view. Once we take ownership of an idea-whether its about politics or sports-what do we do? We love it

disconcerting connotations of the term – the Enterprise Architecture. The asset view of IT will substitute for the outdated project view in my vision for what IT leadership must become. Uncertainty and Risk:

and then, the economics of IT delivery often favored buying a product off the shelf. But when we view IT capabilities as being in a continuous state of transformation, when we see them as tightly integrated senior leadership team includes someone called the CFO, who helps lead the company from the point of view of someone who is an expert in finance; the CMO is someone who contributes expertise in marketing
