ansible how to pass multiple commands

Question

I tried this   - command    configure chdir  src package  - command   usr bin make chdir  src package  - command   usr bin make install chdir  src package    which works but I guess there is something more   neat   So I tried this   from  https   stackoverflow com questions 24043561 multiple-commands-in-the-same-line-for-bruker-topspin which give me back  no such file or directory   - command    configure  usr bin make  usr bin make install chdir  src package    I tried this too  https   u osu edu hasnan 1 2013 12 16 ansible-run-multiple-commands-using-command-module-and-with-items   but I couldn t find the right syntax to put   - command      item     chdir  src package    with items          configure        usr bin make        usr bin make install   That does not work  saying there is a quote issue   Anyone

If a value in YAML begins with a curly brace ({), the YAML parser assumes that it is a dictionary. So, for cases like this where there is a (Jinja2) variable in the value, one of the following two strategies needs to be adopted to avoiding confusing the YAML parser:

Quote the whole command:

- command: "{{ item }} chdir=/src/package/"
  with_items:
  - ./configure
  - /usr/bin/make
  - /usr/bin/make install

or change the order of the arguments:

- command: chdir=/src/package/ {{ item }}
  with_items:
  - ./configure
  - /usr/bin/make
  - /usr/bin/make install

Thanks for @RamondelaFuente alternative suggestion.

Shell works for me  Simply to say  Shell is the same as you run a shell script  Notes   Make sure use   when running multiple cmds  Shell won t return errors if the last cmd is success  just like normal shell  Control it with exit 0 1 if you want to stop ansible when error occurs   The following example shows an error in shell  but it s success at the end of the execution  - name  test shell with an error become  no shell      rm -f  test1    This should be an error    echo  quot test2 quot    echo  quot test1 quot    echo  quot test3 quot    success  This example shows stopinng shell with exit 1 error  - name  test shell with exit 1 become  no shell      rm -f  test1    This should be an error    echo  quot test2 quot    exit 1          this stops ansible due to returning an error   echo  quot test1 quot    echo  quot test3 quot    success  reference  https   docs ansible com ansible latest modules shell module html

I faced the same issue  In my case  part of my variables were in a dictionary i e  with dict variable  looping  and I had to run 3 commands on each item key  This solution is more relevant where you have to use with dict dictionary with running multiple commands  without requiring with items   Using with dict and with items in one task didn t help as it was not resolving the variables   My task was like   - name  Make install git source   command      item       with items      - cd    tools dir       item value artifact dir        - make prefix    tools dir       item value artifact dir    all     - make prefix    tools dir       item value artifact dir    install   with dict      git versions       roles git defaults main yml was   --- tool  git default git  git 2 6 3  git versions    git 2 6 3      git tar name  git-2 6 3 tar gz     git tar dir  git-2 6 3     git tar url  https   www kernel org pub software scm git git-2 6 3 tar gz   The above resulted in an error similar to the following for each    item     for 3 commands as mentioned above   As you see  the values of tools dir is not populated  tools dir is a variable which is defined in a common role s defaults main yml and also item value git tar dir value was not populated resolved    failed   server01 poc jenkins    gt   item cd    tools dir       item value git tar dir       gt    cmd    cd      tools dir         item value git tar dir         failed   true   item    cd    tools dir       item value git tar dir       rc   2  msg   Errno 2  No such file or directory   Solution was easy  Instead of using  COMMAND  module in Ansible  I used  Shell  module and created a a variable in roles git defaults main yml  So  now roles git defaults main yml looks like   --- tool  git default git  git 2 6 3  git versions    git 2 6 3      git tar name  git-2 6 3 tar gz     git tar dir  git-2 6 3     git tar url  https   www kernel org pub software scm git git-2 6 3 tar gz   git pre requisites install cmds   cd    tools dir       item value git tar dir     amp  amp  make prefix    tools dir       item value git tar dir    all  amp  amp  make prefix    tools dir       item value git tar dir    install    or use this if you want git installation to work in   tools git-x x x git pre requisites install cmds   cd    tools dir       item value git tar dir     amp  amp  make prefix  pwd  all  amp  amp  make prefix  pwd  install    or use this if you want git installation to use the default prefix during make   git pre requisites install cmds   cd    tools dir       item value git tar dir     amp  amp  make all  amp  amp  make install    and the task roles git tasks main yml looks like   - name  Make install from git source   shell      git pre requisites install cmds       become user      build user       with dict      git versions       tags      - koba   This time  the values got successfully substituted as the module was  SHELL  and ansible output echoed the correct values  This didn t require with items  loop    cmd    cd   tools git-2 6 3  amp  amp  make prefix  home giga tools git-2 6 3 all  amp  amp  make prefix  home giga tools git-2 6 3 install

To run multiple shell commands with ansible you can use the shell module with a multi-line string  note the pipe after shell    as shown in this example     - name  Build nginx      shell          cd nginx-1 11 13       sudo   configure       sudo make       sudo make install
