How to use template module with different set of variables

Question

My use case is the following     I have a template file  and I would like to create 2 different files from that template  with the variables being filled by a different set of variables for each file   For example  lets say I want to template the file containing the line    mkdir -p   myTemplateVariable     I would like to find a proper way to get this variable filled by  File1  and  File2   Something like    - name  template test 1   template           src myTemplateFile         dest result1   - name  template test 2   template           src myTemplateFile         dest result2   where I could specify for the first templating that the variable to use is a    File1  and for the second  b    File2

I did it in this way   In tasks main yml  - name  template test   template           src myTemplateFile j2         dest   item      with dict  some dict   and in vars main yml  some dict     path to dest1      var1  1     var2  2    path to dest2      var1  3     var2  4   and in templates myTemplateFile j2  some var      item value var1    some other var      item value var2      Hope this solves your problem

You can do this very easy  look my Supervisor recipe   - name  Setup Supervisor jobs files   template      src  job conf j2     dest    etc supervisor conf d    item job    conf      owner  root     group  root     force  yes     mode  0644   with items      -   job  bender  arguments   -m 64   instances  3       -   job  mailer  arguments   -m 1024   instances  2     notify  Ensure Supervisor is restarted   job conf j2    program    item job     user vagrant command  usr share nginx vhosts parclick com app console rabbitmq consumer    item arguments       item job    -e prod process name   program name s   process num 02d numprocs    item instances    autostart true autorestart true stderr logfile  var log supervisor    item job    stderr log stdout logfile  var log supervisor    item job    stdout log   Output   TASK  Supervisor   Setup Supervisor jobs files                                   changed   loc parclick com    gt   item  u instances   3  u job   u bender   u arguments   u -m 64    changed   loc parclick com    gt   item  u instances   2  u job   u mailer   u arguments   u -m 1024      Enjoy

With Ansible 2 x you can use vars  with tasks   Template test j2   mkdir -p   myTemplateVariable     Playbook   - template  src test j2 dest  tmp File1   vars      myTemplateVariable  myDirName  - template  src test j2 dest  tmp File2   vars      myTemplateVariable  myOtherDir   This will pass different myTemplateVariable values into test j2

This is a solution hack I m using   tasks main yml   - name  parametrized template - a   template      src  test j2     dest   tmp templateA   with items  var a  - name  parametrized template - b   template      src  test j2     dest   tmp templateB   with items  var b   vars main yml  var a    -  this is var a  var b    -  this is var b    templates test j2      item      After running this  you get this is var a in  tmp templateA and this is var b in  tmp templateB   Basically you abuse with items to render the template with each item in the one-item list  This works because you can control what the list is when using with items   The downside of this is that you have to use item as the variable name in you template   If you want to pass more than one variable this way  you can dicts as your list items like this   var a    -     var 1   this is var a1      var 2   this is var a2  var b    -     var 1   this is var b1      var 2   this is var b2    and then refer to them in your template like this      item var 1       item var 2

I had a similar problem to solve  here is a simple solution of how to pass variables to template files  the trick is to write the template file taking advantage of the variable  You need to create a dictionary  list is also possible   which holds the set of variables corresponding to each of the file  Then within the template file access them   see below   the template file  test file j2      ansible managed    created by xbalaji gmail com     set dkey     item   splitext  0         set fname   test vars dkey  name        set fip     test vars dkey  ip          set fport   test vars dkey  port     filename     fname    ip address     fip    port     fport      the playbook  ---     file  template test yml   author  xbalaji gmail com     description  playbook to demonstrate passing variables to template files     this playbook will create 3 files from a single template  with different   variables passed for each of the invocation     usage    ansible-playbook -i  localhost   template test yml  - name  template variables testing   hosts  all   gather facts  false    vars      ansible connection  local     dest dir    tmp ansible template test       test files        - file 01 txt       - file 02 txt       - file 03 txt     test vars        file 01          name  file 01 txt         ip  10 0 0 1         port  8001       file 02          name  file 02 txt         ip  10 0 0 2         port  8002       file 03          name  file 03 txt         ip  10 0 0 3         port  8003    tasks      - name  copy the files       template          src  test file j2         dest      dest dir       item           with items          -     test files

Another real world example using a list  an extract for a template for php ini     if  cli php ini  in item d    max execution time   0 memory limit   1024M    else    max execution time   300 memory limit   512M    endif      This is the var  php templates    -   s   php ini j2   d    etc php   php version   apache2 php ini      -   s   php ini j2   d    etc php   php version   cli php ini      Then i deploy with this  - name  push templated files   template      src     item s        dest     item d        mode     item m   default 0644          owner     item o   default  root           group     item g   default  root           backup  yes   with items     php templates

- name  copy vhosts   template  src site-vhost conf dest  etc apache2 sites-enabled    item    conf   with items      - somehost local     - otherhost local   notify  restart apache   IMPORTANT  Note that an item does not have to be just a string  it can be an object with as many properties as you like  so that way you can pass any number of variables   In the template I have    lt VirtualHost   80 gt      ServerAdmin me example org     ServerName    item        DocumentRoot  vagrant public       ErrorLog   APACHE LOG DIR  error-   item    log     CustomLog   APACHE LOG DIR  access log combined   lt  VirtualHost gt

For Ansible 2 x   - name  template test   template       src  myTemplateFile     dest  result1   vars      myTemplateVariable  File1  - name  template test   template       src  myTemplateFile     dest  result2   vars      myTemplateVariable  File2     For Ansible 1 x   Unfortunately the template module does not support passing variables to it  which can be used inside the template  There was a feature request but it was rejected   I can think of two workarounds   1  Include  The include statement supports passing variables  So you could have your template task inside an extra file and include it twice with appropriate parameters   my include yml   - name  template test   template           src myTemplateFile         dest destination   main yml   - include  my include yml destination result1 myTemplateVariable File1  - include  my include yml destination result2 myTemplateVariable File2   2  Re-define myTemplateVariable  Another way would be to simply re-define myTemplateVariable right before every template task   - set fact       myTemplateVariable  File1  - name  template test 1   template           src myTemplateFile         dest result1  - set fact       myTemplateVariable  File2  - name  template test 2   template           src myTemplateFile         dest result2
