Ansible lineinfile module syntax error when using multiple variables in string
When using multiple variables in a string with the lineinfile
module in Ansible, you need to ensure that the syntax is correct to avoid any errors. Here's an example of the correct syntax for using multiple variables in a string with the lineinfile
module:
yaml- name: Add line to a file using lineinfile
lineinfile:
path: /path/to/file
line: "{{ variable1 }} {{ variable2 }} some text"
In this example, variable1
and variable2
are the variables you want to include in the line. Make sure to enclose the line string in double quotes ("
) and use the Ansible variable syntax {{ ... }}
to reference the variables.
If you have more complex requirements, such as conditionally including variables or using complex expressions, you can also use the set_fact
module to create a new variable with the desired value and then use it in the lineinfile
module. Here's an example:
yaml- name: Set dynamic line using set_fact
set_fact:
dynamic_line: "{{ variable1 if condition else variable2 }}"
- name: Add dynamic line to a file using lineinfile
lineinfile:
path: /path/to/file
line: "{{ dynamic_line }} some text"
In this example, variable1
and variable2
are used conditionally based on a certain condition to set the value of dynamic_line
. Then, the dynamic_line
variable is used in the lineinfile
module.
Make sure to adjust the variable names, file paths, and any other parameters as per your specific requirements.
