实例

配置如下：

注意：在实际工作中，一般都会搭建nexus私库给开发用的，而像java这样的项目中很多依赖包的用的都是nexus私库的地址，这时在构建项目时就需要给jenkins配置私库的配置文件，即在/var/lib/jenkins/.m2/下添加settings.xml配置文件。

下面附上这个实例中salt的所用到的sls文件，如下：

sls文件所在的位置：

[root@test11 deploy]# ls /srv/salt/state/deploy/
files  java.sls
[root@test11 deploy]# ls /srv/salt/state/deploy/files/java/
service-7.sh  system.sh

发送项目到相应服务器运行的java.sls文件：

[root@test11 deploy]# cat /srv/salt/state/deploy/java.sls 
{% set project_name = pillar['project']['name'] -%}
base_dirs:
  file.directory:
    - names:
      - /ubox/apps/{{ project_name }}
      - /ubox/logs/{{ project_name }}
      - /ubox/share/config/{{ project_name }}
      - /var/run/java
    - user: root
    - group: root
    - dir_mode: 755
    - makedirs: True

release_code:
  cmd.run:
    - name: rsync -rl {%- if salt['pillar.get']('project:clean') %} --delete {%- endif %} test11.uboxol.com::artifacts/{{ project_name }}/ /ubox/apps/{{ project_name }}

    - source: salt://deploy/files/java/service-7.sh
    - user: root
    - group: root

    - mode: 755
    - template: jinja
    - require:

  cmd.run:
    - name: systemctl daemon-reload

project_service:
  service.running:
    - name: {{ project_name | replace('/', '_') }}
    - require:
      - file: system_scripts
    - watch:
      - cmd: release_code

{%- if salt['pillar.get']('project:tmp_dirs') %}

tmp_dirs:
  file.directory:
    - user: root
    - group: root
    - dir_mode: 755
    - makedirs: True
    - names:
    {%- for tmp_dir in salt['pillar.get']('project:tmp_dirs') %}
      - /ubox/apps/{{ project_name }}/{{ tmp_dir }}
    {%- endfor %}
    - require:
      - cmd: release_code
{%- endif %}
