这个模块可以通过在playbook中定义变量来设置环境变量,也可以通过在task中使用`environment`关键字来设置。 ```yaml - name: Set environment variables hosts: all tasks: - name: Set JAVA_HOME variable environment: JAVA_HOME: "/usr/lib/jvm/java-11" become: yes - name: Set PATH variable environment:...
tags用于让用户选择运行或略过playbook中的部分代码。Ansible具有幂等性,因此会自动跳过没有变化的部分;但是当一个playbook任务比较多时,一个一个的判断每个部分是否发生了变化,也需要很长时间。因此,如果确定某些部分没有发生变化,就可以通过tags跳过这些代码片断。 3、Playbook执行结果解析 使用ansible-playbook运行playboo...
- name: Set environment variable shell: echo "MY_ENV_VAR=my_value" >> /etc/environment environment: MY_ENV_VAR: my_value become: yes - name: Use environment variable shell: echo $MY_ENV_VAR ``` 通过以上Playbook中的任务,我们首先将MY_ENV_VAR设置为my_value并写入到/etc/environment文件中。
Ansible Environment variables are used to set the environment variable for action on the remote host using the environment keyword, which can be set at the playbook or task level and doesn’t affect the Ansible configuration file or the environment set for the user. It doesn’t automatically in...
ansible-playbook release.yml --extra-vars "hosts=vipers user=starbuck"从Ansible 1.2开始,您还可以传入额外的var,如引用的JSON,如下所示: key=value @ --extra-vars“@ some_file.json” 也可以从Ansible 1.3,额外的vars可以格式化为YAML,无论是在命令行还是在上面的文件中。 Variable Precedence: Where...
true和yes,on或者1都是一样的意思,一般在模块参数里面用yes和no,true和false在playbook中其他地方。 另外,比如下面的模块参数分行写,可以在第一行写 > , 后面几行跟参数来实现。 注意notify是严格按照它在play中定义的顺序执行的,而不是notify调用的顺序执行的。比如下面的playbook,尽管先notify的是handler test2,...
We can access the environment variables in an Ansible playbook and roles using the lookup plugin. An example is as follows: --- - hosts: localhost tasks: - name: Print HOME environment variable debug: msg: "{{ lookup('env', 'HOME') }}" ...
执行的文件称为playbook,文件格式为yaml。ansible简约而不简单。比起puppet的繁琐的配置和复杂语法(Puppet基础篇4-安装、配置并使用Puppet | Puppet运维自动化经验分享),简直是一股清流。 图2描述了ansible执行过程,执行了两个task和一个handler,先是使用了一个apt模块在web1,web2,web3上面执行了安装nginx的任务,再...
If your environment doesn't have a problem securing # stdout from ansible-playbook (or you have manually specified no_log in your # playbook on all of the tasks where you have secret information) then you can # safely set this to True to get more informative messages. #display_args_to_...
