Ansible and Wget

Question

I am trying to wget a file from a web server from within an Ansible playbook.

Here is the Ansible snippet:

--- - hosts: all   sudo: true   tasks:   - name: Prepare Install folder     sudo: true     action: shell sudo mkdir -p /tmp/my_install/mysql/ && cd /tmp/my_install/mysql/   - name: Download MySql     sudo: true     action: shell sudo wget http://{{ repo_host }}/MySQL-5.6.15-1.el6.x86_64.rpm-bundle.tar  

Invoking it via:

ansible-playbook my_3rparties.yml -l vsrv644 --extra-vars "repo_host=vsrv656" -K -f 10  

It fails with the following:

Cannot write to `MySQL-5.6.15-1.el6.x86_64.rpm-bundle.tar' (Permission denied). FATAL: all hosts have already failed -- aborting  PLAY RECAP ********************************************************************             to retry, use: --limit @/usr2/ihazan/vufroria_3rparties.retry  vsrv644                : ok=2    changed=1    unreachable=0    failed=1    

When trying to do the command that fail via regular remote ssh to mimic what ansible would do, it doesn't work as follows:

-bash-4.1$ ssh ihazan@vsrv644 'cd /tmp/my_install/mysql && sudo wget http://vsrv656/MySQL-5.6.15-1.el6.x86_64.rpm-bundle.tar' Enter passphrase for key '/usr2/ihazan/.ssh/id_rsa':  sudo: sorry, you must have a tty to run sudo 

But I can solve it using -t as follows:

-bash-4.1$ ssh -t ihazan@vsrv644 'cd /tmp/my_install/mysql && sudo wget http://vsrv656/MySQL-5.6.15-1.el6.x86_64.rpm-bundle.tar' 

Then it works.

Is there a way to set the -t (pseudo tty option) on ansible?

P.S: I could solve it by editing the sudoers file as others propose but that is a manual step I am trying to avoid.

Don't use shell-module when there is specialized modules available. In your case:

Create directories with file-module:

- name: create project directory {{ common.project_dir }}   file: state=directory path={{ common.project_dir }} 

Download files with get_url-module:

- name: download sources   get_url: url={{ opencv.url }} dest={{ common.project_dir }}/{{ opencv.file }} 

Note the new module call syntax in the examples above.

If you have to use sudo with password remember to give --ask-sudo-pass when needed (see e.g. Remote Connection Information).
