git clone is not working in Cron jobs

[balubhai555]

Hello  Team,

I want to clone the git repository using ansible Cron module. I am trying to change the local repository for every 5 mintes using Cron module in ansible playbook. For that i wrote the code as below.

The below cron job is not working for git clone.

  - cron:

      name: "download the git folder using cron jobs"

      minute: "5"

      job: 'sudo "git clone --depth=1 --force=yes https://github.com/Msutapalli/openwhisk.git"  > /home/ec2-user/siva/openw/'

      cron_file: "/etc/crontab"

      state: present

      user: ec2-user

      user: root

 But for sample  

  - cron:

      name: "Sample hello"

      minute: "5"

      job: 'sudo echo " heloworld " > /home/ec2-user/hello.txt'

      cron_file: "/etc/crontab"

      state: present

      user: ec2-user

      user: root

It is working fine.

where i did wrong in my 'job: ' command.

Thanks in advance

a few issues:

- 'user' is defined twice?

- you are sudo'ing from a cronjob - why not manipulate the target user's cronjob directly?

- the output of git is redirected to a directory, I guess you either meant to clone into this directory, or redirect the output to a file (output != repository location)

So why not create a playbook that does this and run it from cron? ;)

Drop the double quotes.
Also, a filename seems to be missing in your stdout redirection.

$ sudo "git help"
sudo: git help: command not found

$ sudo git help
usage: git [--version] [--help] [-C <path>] [-c name=value]
[..]

Notice 'echo' is not in the double quotes.

-Sndr.

Yes Dick, You are right.

1.) 'user' defined twice because my intention is to use the cron job for both users.

2.) Yes, I tried without sudo, But no effect with sudo or without sudo'ing in the clone.

3.) Yes, you are right. I am trying to store the repository into those folder. 

Can you suggest me more changes to work with cron with git clone.

That's unlikely to work. If you actually do want that, I suggest iterating over a list of users using 'with_items'.

(If it does work then it needs documentation.)

Don't use it as it complicates things for no reason.

cron schedules commands, and the ansible cron module is a convenient way to configure it (timing, user, etc).

The problem is that your command doesn't work.

Scheduling something that doesn't work has the same result: it still doesn't work.

So fix your command first, and once it works you can try to schedule it.

Hint: make sure you are able to clone a git repository into a specific directory: https://git-scm.com/docs/git-clone

I'm not sure if repeatedly cloning a git repo is actually useful, so make sure you understand what the implications are of doing that (or come up with a different approach).
