AI组定制化ISO编译环境构建。

虚拟机准备

创建磁盘文件（后续用于直接迁移虚拟机):

# qemu-img create -f qcow2 ai_ubuntu.qcow2 40G

创建qemu虚拟机，使用ISO(ubuntu-16.04.4-server-amd64.iso)安装, CPU/内存可参考下图:

虚拟机名称如下:

网络配置选择default， 后续我们将设置IP地址为192.168.122.166.

虚拟机安装

安装过程中，配置主机名为aiubuntu, 默认用户名为build/thinker@1.

磁盘分区采用lvm, 默认如下：

接下来的包选择里选择上openssh server, 之后继续安装，直到安装完毕。

虚拟机配置

设置root密码， 允许sshd对root的登录。配置固定IP地址:

# vim /etc/network/interfaces
auto ens3
iface ens3 inet static
address 192.168.122.166
netmask 255.255.255.0
network 192.168.122.0
broadcast 192.168.122.255
gateway 192.168.122.1
dns-nameservers 192.168.122.1

配置gitlab-ce源，安装gitlab-ce/gitlab-runner等。

# apt-get install -y dpkg-dev  xorriso
# apt-get install gitlab-ce postfix gitlab-runner

配置gitlab-ce:

# vim /etc/gitlab/gitlab.rb
external_url 'http://192.168.122.252'
# gitlab-ctl reconfigure && gitlab-ctl restart

CI/CD配置

配置密码为thinker@1,

登录(root/thinker@1):

更改gitlab-runner的配置:

# vim /etc/systemd/system/gitlab-runner.service
ExecStart=/usr/bin/gitlab-runner "run" "--working-directory" "/home/gitlab-runner" "--config" "/etc/gitlab-runner/config.toml" "--service" "gitlab-runner" "--syslog" "--user" "root"
# systemctl daemon-reload
# systemctl restart gitlab-runner

安装docker-ce, load auto-index镜像，而后创建8888端口的http服务，服务目录为/opt/serve端口。这一步骤可以用别的静态网页服务器来进行。

创建三个project,

deploy_cd:

# cd /root/git/deploy_cd
# git config --global user.name "Administrator"
# git config --global user.email "admin@example.com"
# git init
# git remote add origin http://192.168.122.166/root/deploy_cd.git
# git add .
# git commit -m "Initial commit"
# git push -u origin master

Setting->CI/CD->Runners Settings:

注册gitlab-runner:

# gitlab-ci-multi-runner register
Running in system-mode.                            
                                                   
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://192.168.122.166
Please enter the gitlab-ci token for this runner:
y2GStHWxWgpt7hj_Azm_
Please enter the gitlab-ci description for this runner:
[aiubuntu]: deploy_cd
Please enter the gitlab-ci tags for this runner (comma separated):
deploy_cd_tag
Registering runner... succeeded                     runner=y2GStHWx
Please enter the executor: shell, ssh, docker, docker-ssh, parallels, virtualbox, docker+machine, docker-ssh+machine, kubernetes:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 

设置trigger项:

依次类推，创建另外两个project, kismatic_source和node_cd， 并设置对应的gitlab-runner.

此后的任意一次提交将触发编译。

Trigger配置, 在deploy_cd的工程中，新建一个trigger:

对应得到的字段:

用字段替换kismatic_source下的文件.gitlab-ci.yml中的字段:

    "curl -X POST -F token=2d529be0fe3bd421ce491652a34c7d -F ref=master http://192.168.122.252/api/v4/projects/1/trigger/pipeline"

提交kismatic_source的更改，查看是否编译成功。

编译完后的文件可以在`/home/gitlab-runner/builds下找到。

集群安装

文件列表:

1604_deploy.iso
1604_node.iso

分别对应deploy节点和node节点。下列假设，deploy节点为192.168.122.154, node节点为192.168.122.122, 对应需要配置如下:

deploy节点安装后操作(192.168.122.154):

# cd /root/
# ./initial.sh
# vim /etc/bind/db.teligen.com
....
ubuntu	IN      A       192.168.122.122
.....
# systemctl restart bind9

node节点配置(192.168.122.122):

# vim /etc/network/interfaces
....
	dns-nameservers 192.168.122.154
....
# systemctl restart networking

安装集群(192.168.122.154)：

# cd /root/ansible/kismatic/cluster00
# ./kismatic install apply
....

安装完毕后，验证(192.168.122.122):

# kubectl get nodes
NAME                 STATUS    ROLES     AGE       VERSION
ubuntu.teligen.com   Ready     master    9m        v1.10.5
