Ansible: How to delete files and folders inside a

问题:

The below code only deletes the first file it gets inside the web dir. I want to remove all the files and folders inside the web directory and retain the web directory. How can I do that?

  - name: remove web dir contents
     file: path='/home/mydata/web/{{ item }}' state=absent
     with_fileglob:
       - /home/mydata/web/*

Note: I've tried rm -rf using command and shell, but they don't work. Perhaps I am using them wrongly.

Any help in the right direction will be appreciated.

I am using ansible 2.1.0.0

回答1:

Below code will delete the entire contents of artifact_path

- name: Clean artifact path
  file:
    state: absent
    path: "{{ artifact_path }}/"

Note: this will delete the directory too.

回答2:

Using shell module:

- shell: /bin/rm -rf /home/mydata/web/*

Cleanest solution if you don't care about creation date:

- file: path=/home/mydata/web state=absent
- file: path=/home/mydata/web state=directory

Remove the directory (basically a copy of https://stackoverflow.com/a/38201611/1695680), Ansible does this operation with rmtree under the hood.

- name: remove files and directories
  file:
    state: "{{ item }}"
    path: "/srv/deleteme/"
    owner: 1000  # set your owner, group, and mode accordingly
    group: 1000
    mode: '0777'
  with_items:
    - absent
    - directory

If you don't have the luxury of removing the whole directory and recreating it, you can scan it for files, (and directories), and delete them one by one. Which will take a while. You probably want to make sure you have [ssh_connection]\npipelining = True in your ansible.cfg on.

- block:
  - name: 'collect files'
    find:
      paths: "/srv/deleteme/"
      hidden: True
      recurse: True
      # file_type: any  # Added in ansible 2.3
    register: collected_files

  - name: 'collect directories'
    find:
      paths: "/srv/deleteme/"
      hidden: True
      recurse: True
      file_type: directory
    register: collected_directories

  - name: remove collected files and directories
    file:
      path: "{{ item.path }}"
      state: absent
    with_items: >
      {{
        collected_files.files
        + collected_directories.files
      }}

回答4:

try the below command, it should work

- shell: ls -1 /some/dir
  register: contents

- file: path=/some/dir/{{ item }} state=absent
  with_items: {{ contents.stdout_lines }}

I really didn't like the rm solution, also ansible gives you warnings about using rm. So here is how to do it without the need of rm and without ansible warnings.

- hosts: all
  tasks:
  - name: Ansible delete file glob
    find:
      paths: /etc/Ansible
      patterns: "*.txt"
    register: files_to_delete

  - name: Ansible remove file glob
    file:
      path: "{{ item.path }}"
      state: absent
    with_items: "{{ files_to_delete.files }}"

回答6:

Using file glob also it will work. There is some syntax error in the code you posted. I have modified and tested this should work.

- name: remove web dir contents
  file:
    path: "{{ item }}"
    state: absent
  with_fileglob:
    - "/home/mydata/web/*"

Created an overall rehauled and fail-safe implementation from all comments and suggestions:

# collect stats about the dir
- name: check directory exists
  stat:
    path: '{{ directory_path }}'
  register: dir_to_delete

# delete directory if condition is true
- name: purge {{directory_path}}
  file:
    state: absent
    path: '{{ directory_path  }}'
  when: dir_to_delete.stat.exists and dir_to_delete.stat.isdir

# create directory if deleted (or if it didn't exist at all)
- name: create directory again
  file:
    state: directory
    path: '{{ directory_path }}'
  when: dir_to_delete is defined or dir_to_delete.stat.exist == False

回答8:

While Ansible is still debating to implement state = empty https://github.com/ansible/ansible-modules-core/issues/902

my_folder: "/home/mydata/web/"
empty_path: "/tmp/empty"


- name: "Create empty folder for wiping."
  file:
    path: "{{ empty_path }}" 
    state: directory

- name: "Wipe clean {{ my_folder }} with empty folder hack."
  synchronize:
    mode: push

    #note the backslash here
    src: "{{ empty_path }}/" 

    dest: "{{ nl_code_path }}"
    recursive: yes
    delete: yes
  delegate_to: "{{ inventory_hostname }}"

Note though, with synchronize you should be able to sync your files (with delete) properly anyway.

回答9:

There is an issue open with respect to this.

For now, the solution works for me: create a empty folder locally and synchronize it with the remote one.

Here is a sample playbook:

- name: "Empty directory"
  hosts: *
  tasks:
    - name: "Create an empty directory (locally)"
      local_action:
        module: file
        state: directory
        path: "/tmp/empty"

    - name: Empty remote directory
      synchronize:
        src: /tmp/empty/
        dest: /home/mydata/web/
        delete: yes
        recursive: yes

I want to make sure that the find command only deletes everything inside the directory and leave the directory intact because in my case the directory is a filesystem. The system will generate an error when trying to delete a filesystem but that is not a nice option. Iam using the shell option because that is the only working option I found so far for this question.

What I did:

Edit the hosts file to put in some variables:

[all:vars]
COGNOS_HOME=/tmp/cognos
find=/bin/find

And create a playbook:

- hosts: all
  tasks:
  - name: Ansible remove files
    shell: "{{ find }} {{ COGNOS_HOME }} -xdev -mindepth 1 -delete"

This will delete all files and directories in the COGNOS_HOME variable directory/filesystem. The "-mindepth 1" option makes sure that the current directory will not be touched.

回答11:

Assuming you are always in Linux, try the find cmd.

- name: Clean everything inside {{ item }}
  shell: test -d {{ item }} && find {{ item }} -path '{{ item }}/*' -prune -exec rm -rf {} \;
  with_items: [/home/mydata/web]

This should wipe out files/folders/hidden under /home/mydata/web

先删除对应的目录，然后在创建该目录，使用的是嵌套循环

  - name: delete old data and clean cache
    file:
      path: "{{ item[0] }}" 
      state: "{{ item[1] }}"
    with_nested:
      - [ "/data/server/{{ app_name }}/webapps/", "/data/server/{{ app_name }}/work/" ]
      - [ "absent", "directory" ]
    ignore_errors: yes

Below worked for me,

- name: Ansible delete html directory
  file:
   path: /var/www/html
   state: directory
