首先看一下目錄結構(沒用的已經刪掉):

1)、pillar
[root@k8s_master saltstack-haproxy]# tree pillar/ pillar/ └── base ├── top.sls └── zabbix └── agent.sls 2 directories, 2 files [root@k8s_master base]# cat base/top.sls base: ‘*‘: - zabbix.agent [root@k8s_master base]# cat base/zabbix/agent.sls #配置zabbix server的變量及值zabbix-agent: Zabbix_Server: 192.168.56.21
2)、salt(目錄結構看上面)
[root@k8s_master base]# cat top.sls base: ‘*‘: - init.env_init ##首先跳到init目錄下的環境初始化sls prod: #然後跳到對所有主機安裝haproxy 目錄下的sls ‘*‘: - cluster.haproxy-outside - cluster.haproxy-outside-keepalived - web.bbs ‘saltstack-node2.example.com‘: #最後對特定主機安裝memcache服務- memcached.service
2.1)、init目錄(入口)
#目錄結構:
[root@k8s_master base]# tree init/ init/ ├── audit.sls ├── dns.sls ├── env_init.sls ├── epel.sls ├── files │ ├── resolv.conf │ └── zabbix_agentd.conf ├── history.sls ├── sysctl.sls └── zabbix_agent.sls 1 directory, 9 files
入口sls文件為env_init.sls
[root@k8s_master init]# cat env_init.sls include: - init.dns - init.history - init.audit - init.sysctl - init.epel - init.zabbix_agent
對初始化環境sls文件進行分析(根據eve_init.sls中的位置依次查看)
[root@k8s_master init]# cat dns.sls /etc/resolv.conf: file.managed: - source: salt://init/files/resolv.conf #表示將source所指目錄下的文件覆蓋到/etc/resolv.conf - user: root - gourp: root - mode: 644
#其他用法
[root@k8s_master salt] cat test.sls
test:
file.managed:
- name: /tmp/aaa.txt
- source: salt://top.sls #表示將source目錄下文件覆蓋到/tmp/目錄下並命名為aaa.txt(此處不能直接寫目錄名稱)
[root@k8s_master init]# cat history.sls /etc/profile: file.append: - text: - export HISTTIMEFORMAT="%F %T `whoami` " [root@k8s_master init]# cat audit.sls /etc/bashrc: file.append: - text: - export PROMPT_COMMAND=‘{ msg=$(history 1 | { read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }‘ [root@k8s_master init]# cat sysctl.sls net.ipv4.ip_local_port_range: sysctl.present: - value: 10000 65000 fs.file-max: sysctl.present: - value: 2000000 net.ipv4.ip_forward: sysctl.present: - value: 1 vm.swappiness: sysctl.present: - value: 0 [root@k8s_master init]# cat epel.sls yum_repo_release: pkg.installed: - sources: - epel-release: http://mirrors.aliyun.com/epel/6/x86_64/epel-release-6-8.noarch.rpm - unless: rpm -qa | grep epel-release-6-8 [root@k8s_master init]# cat zabbix_agent.sls zabbix-agent: pkg.installed: - name: zabbix22-agent file.managed: - name: /etc/zabbix_agentd.conf - source: salt://init/files/zabbix_agentd.conf - template: jinja - defaults: Server: {{ pillar[‘zabbix-agent‘][‘Zabbix_Server‘] }} - require: - pkg: zabbix-agent service.running: - enable: True - watch: - pkg: zabbix-agent - file: zabbix-agent zabbix_agentd.conf.d: file.directory: - name: /etc/zabbix_agentd.conf.d - watch_in: - service: zabbix-agent - require: - pkg: zabbix-agent - file: zabbix-agent
