get_url newbie question

[Daniel Laird]

All,

New to ansible and struggling a bit.

I want to use get_url on a list of files.  But also due to issues with the server I am downloading from I want to retry the download on failure.

I have something like this:

- name: Download the packages

  get_url: url=pkg_name.tar.bz2 dest=/opt/DIR_NAME force=yes url_password={{ svn_password }} url_username={{ svn_username }} use_proxy=no

  register: get_url_result

  until: get_url_result.rc == 0

  retries: 5

  delay: 10

  with_items: pkg_list

Is this possible?

I cant seem to get the logic right or find out what the get_url returns in the failure case.

I just want to try no more than 5 times for each pkg in the package list.

Cheers

Dan

A good way to check a return value is:

- debug: var=registered_variable_name

In this case, you should get an arrayed result.

Let us know what specific problems you are having as I have trouble parsing what "doesn't work" means usually :)

Thanks!

For the benefit of all this seemed to solve it:

  get_url: url=pkg_name.tar.bz2 dest=/opt/DIR_NAME force=yes url_password={{ svn_password }} url_username={{ svn_username }} use_proxy=no

  register: get_url_result

  until: "'OK' in get_url_result.msg"

  retries: 5

  delay: 10

  with_items: pkg_list

cheers

If the file is already present, then the get_url_result.msg does not contain 'OK'. I had to use
until: "'OK' in get_url_result.msg or 'file already exists' in get_url_result.msg"

Actually, this works just fine (tested with ansible-playbook 2.1.1.0)

until: get_url_result | succeeded
