What's the easy way to auto create non existing dir in ansible

Question

In my Ansible playbook many times i need to create file there

 - name: Copy file
   template:
     src: code.conf.j2
     dest: \"{{project_root}}/conf/code.         


        

Answer 1

Right now, this is the only way

- name: Ensures {{project_root}}/conf dir exists
  file: path={{project_root}}/conf state=directory
- name: Copy file
  template:
    src: code.conf.j2
    dest: "{{project_root}}/conf/code.conf"

Answer 2

According to the latest document when state is set to be directory, you don't need to use parameter recurse to create parent directories, file module will take care of it.

- name: create directory with parent directories
  file:
    path: /data/test/foo
    state: directory

this is fare enough to create the parent directories data and test with foo

please refer the parameter description - "state" http://docs.ansible.com/ansible/latest/modules/file_module.html

copy module creates the directory if it's not there. In this case it created the resolved.conf.d directory

- name: put fallback_dns.conf in place                                                                 
  copy:                                                                                                
    src: fallback_dns.conf                                                                             
    dest: /etc/systemd/resolved.conf.d/                                                                
    mode: '0644'                                                                                       
    owner: root                                                                                        
    group: root                                                                                        
  become: true

To ensure success with a full path use recurse=yes

- name: ensure custom facts directory exists
    file: >
      path=/etc/ansible/facts.d
      recurse=yes
      state=directory

Answer 5

you can create the folder using the following depending on your ansible version.

Latest version 2<

- name: Create Folder
  file: 
   path: "{{project_root}}/conf"
   recurse: yes
   state: directory

Older version:

- name: Create Folder
  file: 
      path="{{project_root}}/conf"
      recurse: yes
      state=directory

If you are running Ansible >= 2.0 there is also the dirname filter you can use to extract the directory part of a path. That way you can just use one variable to hold the entire path to make sure both tasks never get out of sync.

So for example if you have playbook with dest_path defined in a variable like this you can reuse the same variable:

- name: My playbook
  vars:
    dest_path: /home/ubuntu/some_dir/some_file.txt
  tasks:

    - name: Make sure destination dir exists
      file:
        path: "{{ dest_path | dirname }}"
        state: directory
        recurse: yes

    # now this task is always save to run no matter how dest_path get's changed arround
    - name: Add file or template to remote instance
      template: 
        src: foo.txt.j2
        dest: "{{ dest_path }}"
