Re: [ansible-project] How to create multiple folders with loop in ansible

[David Karban]

Hi Deborah,

use with_items:

- name: Creating multiple tomcat instance

  file: dest=/var/lib/tomcat-instance{{ item }}  state=directory

  with_items:
    - 1
    - 2
    - 3

Or, maybe better way with_sequence:
- name: Creating multiple tomcat instance

  file: dest=/var/lib/tomcat-instance{{ item }}  state=directory

  with_sequence: start=1 end=3

I am trying to create multiple directories with different names e.g tomacat-1, tomcat-2 etc..

But i want to do this in the form of a loop. Kindly help me with the yaml syntax.

this is what i tried

 

- name: Creating multiple tomcat instance

  file: dest=/var/lib/tomcat-instance{1..3}  state=directory

But instead of creating three directories, it creates only one with name "tomcat-instance{1..3}"

Also i would like each of these folders to have a unique port id and shutdown port  e.g     -p  8000  -c 8006

Hi, you can do something like:

  - name: create dirs

    file: dest=/tmp/tomcat-instance{{ item }} state=directory

    with_sequence: start=1 end=3

    register: dies

  - debug: var=dirs.results

  - name: do something with tomcat

    shell: echo "sudo tomcat-instance1-create -p {{ 8080 + (item.item | int) }} -c {{ 8005 + (item.item | int) }} name{{ item.item }}"

    with_items:

      - "{{ dirs.results }}"

    register: something

  - debug: var=something.results

Register with debug can produce a lot of interesting information about tasks )
