 - `user` is the user you&#39;re ssh&#39;ing as. With your config, you&#39;re ssh&#39;ing as `deploy`.

 - `sudo_user` is the user you&#39;re sudo&#39;ing on the host when `sudo: yes` is set. 

So I think in your case none of `sudo` and `sudo_user` are necessary if you can ssh as `deploy`.

However, if you ssh as root, you need to set 
`sudo_user: deploy` and `sudo: yes`.

If you ask for &#39;sudo&#39; but don&#39;t specify any user, Ansible will use the default set in your `~/.ansible.cfg` (`sudo_user`), and will default to `root`.

Note that `user` is deprecated (because it&#39;s confusing). You should use `remote_user` instead.

EDIT: Case #2 probably hangs because of ssh confirmation issues : you probably have bitbucket.org host key in `~deploy/.ssh/known_hosts` but **NOT** in `~root/.ssh/known_hosts`


UPDATE: As of Ansible 2.x, use `become` and `become_user` instead of the deprecated `sudo` and `sudo_user`. Example usage:

    - hosts: all
      user: deploy
      become: true
      become_user: deploy

      tasks:
          - name: Ensure code directory
            file: dest=/home/deploy/code state=directory

          - name: Deploy app

So I have done some research, and after defining you button as an object by the code

    private Button buttonname;
    buttonname = (Button) findViewById(R.id.buttonnameinandroid) ;

here is my problem

    buttonname.setOnClickListener(this); //as I understand it, the &quot;**this**&quot; denotes the current `view(focus)` in the android program

then your `OnClick()` event...

Problem:

When I type in the &quot;this&quot;, it says:

    setOnClickListener (Android.View.view.OnClickListener) in View cannot be applied to (com.helloandroidstudio.MainActivity)

I have no idea why?

here is the code from the .java file

    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.TextView;
    
    public class MainActivity extends ActionBarActivity {
    
        private Button btnClick;
        private EditText Name, Date;
        private TextView msg, NameOut, DateOut;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            btnClick = (Button) findViewById(R.id.button) ;
            btnClick.setOnClickListener(this);

            }
        }

                    NameOut = Name;
                    DateOut = Date;

                else
                {

                    msg.setVisibility(View.VISIBLE);
                }
            }
            return;

I have read the Ansible documentation but I am still a bit confused about the three following parameters in ansible playbooks: user, sudo, sudo_user. 

I have tried the following playbooks with different combination of the parameters:

1. user:deploy =&gt; Works

2. user:deploy and sudo: True =&gt; **Hangs on the git task**

3. user:deploy, sudo: True and sudo_user: deploy =&gt; Works

What does sudo_user actually do?
When and why should I use each of these combinations?

    - hosts: all
      user: deploy
      sudo: True
      sudo_user: deploy
     
      tasks:
          - name: Ensure code directory
            file: dest=/home/deploy/code state=directory
      
          - name: Deploy app
            git: repo=git@bitbucket.org:YAmikep/djangotutorial.git dest=/home/deploy/code


Thanks

Occasionally I run into [comments or responses][1] that state emphatically that running `pip` under `sudo` is &quot;wrong&quot; or &quot;bad&quot;, but there are cases (including the way I have a bunch of tools set up) where it is either much simpler, or even necessary to run it that way.

What are the risks associated with running `pip` under `sudo`?

---

Note that this is not the same question as [this one][2], which, despite the title, provides no information about risks. This also isn&#39;t a question about how to avoid using `sudo`, but about specifically why one would want to.

What are the risks of running &#39;sudo pip&#39;?

I am trying to compile some sources using a makefile. In the makefile there is a bunch of commands that need to be ran as `sudo`. 

When I compile the sources from a terminal all goes fine and the make is paused the first time a `sudo` command is ran waiting for password. Once I type in the password, make resumes and completes.

But I would like to be able to compile the sources in NetBeans. So, I started a project and showed netbeans where to find the sources, but when I compile the project it gives the error:

    sudo: no tty present and no askpass program specified

The first time it hits a `sudo` command.

I have looked up the issue on the internet and all the solutions I found point to one thing: disabling the password for this user. Since the user in question here is root. I do not want to do that.

Is there any other solution?

Normally, docker containers are run using the user **root**. I&#39;d like to use a different user, which is no problem using docker&#39;s USER directive. But this user should be able to use **sudo** inside the container. This command is missing.

Here&#39;s a simple Dockerfile for this purpose:

    FROM ubuntu:12.04
    
    RUN useradd docker &amp;&amp; echo &quot;docker:docker&quot; | chpasswd
    RUN mkdir -p /home/docker &amp;&amp; chown -R docker:docker /home/docker
       
    USER docker
    CMD /bin/bash

Running this container, I get logged in with user &#39;docker&#39;. When I try to use sudo, the command isn&#39;t found. So I tried to install the *sudo* package inside my Dockerfile using 

    RUN apt-get install sudo

This results in *Unable to locate package sudo*

While installing pip and python I have ran into a that says:

&gt;The directory &#39;/Users/Parthenon/Library/Logs/pi&#39; or its parent directory is not owned by the current user and the debug log has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want the -H flag.

because I now have to install using `sudo`.

I had python and a handful of libraries already installed on my Mac, I&#39;m running Yosemite. I recently had to do a clean wipe and then reinstall of the OS. Now I&#39;m getting this prompt and I&#39;m having trouble figuring out how to change it

Before my command line was `Parthenon$` now it&#39;s `Philips-MBP:~ Parthenon$`

I am the sole owner of this computer and this is the only account on it. This seems to be a problem when upgrading to python 3.4, nothing seems to be in the right place, virtualenv isn&#39;t going where I expect it to, etc.  

pip install: Please check the permissions and owner of that directory

I&#39;m new to Ubuntu and Linux in general. I want to code in Java on my computer, but I&#39;m having problems installing [IntelliJ IDEA][1] on Ubuntu. I have downloaded and extracted the file and for some reason renamed the folder to idea. I tried moving the folder to `/usr/share/applications` or something but I didn&#39;t have permission. I used `sudo -i` in terminal to gain permission but didn&#39;t manage to get out of root folder. Can anyone help me with a step by step way to move the folder, create a shortcut in the search bar or whatever it&#39;s called and install it properly?

I would like to quickly monitor some hosts using commands like ps,dstat etc using ansible-playbook. The `ansible` command itself perfectly does what I want, for instance I&#39;d use:

    ansible -m shell -a &quot;ps -eo pcpu,user,args | sort -r -k1 | head -n5&quot;

and it nicely prints all std output for every host like this:

    localhost | success | rc=0 &gt;&gt;
    0.0 root     /sbin/init
    0.0 root     [kthreadd]
    0.0 root     [ksoftirqd/0]
    0.0 root     [migration/0]

    otherhost | success | rc=0 &gt;&gt;
    0.0 root     /sbin/init
    0.0 root     [kthreadd]
    0.0 root     [ksoftirqd/0]
    0.0 root     [migration/0] 

However this requires me to keep a bunch of shell scripts around for every task which is not very &#39;ansible&#39; so I put this in a playbook:

    ---
    -
      hosts: all
      gather_facts: no
      tasks:
        - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5

and run it with `-vv`, but the output baiscally shows the dictionary content and newlines are not printed as such so this results in an unreadable mess like this:

    changed: [localhost] =&gt; {&quot;changed&quot;: true, &quot;cmd&quot;: &quot;ps -eo pcpu,user,args | sort -r -k1 
    head -n5 &quot;, &quot;delta&quot;: &quot;0:00:00.015337&quot;, &quot;end&quot;: &quot;2013-12-13 10:57:25.680708&quot;, &quot;rc&quot;: 0,
    &quot;start&quot;: &quot;2013-12-13 10:57:25.665371&quot;, &quot;stderr&quot;: &quot;&quot;, &quot;stdout&quot;: &quot;47.3 xxx    Xvnc4 :24
    -desktop xxx:24 (xxx) -auth /home/xxx/.Xauthority -geometry 1920x1200\n
    .... 

 I also tried adding `register: var` and the a &#39;debug&#39; task to show `{{ var.stdout }}` but the result is of course the same.

Is there a way to get nicely formatted output from a command&#39;s stdout/stderr when run via a playbook? I can think of a number of possible ways (format output using sed? redirect output to file on the host then get that file back and echo it to the screen?), but with my limited knowledge of the shell/ansible it would take me a day to just try it out.


Ansible playbook shell output

Some of tasks I wrote start and never end. Ansible does not provide any errors or logs that would explain this, even with -vvvv option. Playbook just hangs and passing hours doesn&#39;t change anything.

When I try to run my tasks manually (by entering commands via SSH) everything is fine. 

Example task that hangs:

    - name: apt upgrade
      shell: apt-get upgrade

Is there any way to see stdout and stderr ? I tried:

    - name: apt upgrade
      shell: apt-get upgrade
      register: hello
    - debug: msg=&quot;{{ hello.stdout }}&quot;
    - debug: msg=&quot;{{ hello.stderr }}&quot;

but nothing changed.

I do have required permissions and I pass correct sudo password - other tasks that require sudo execute correctly.

How to detect why Ansible playbook hangs during execution

I&#39;d like to able to run an ansible task only if the host of the current playbook __does not belong__ to a certain group. In semi pseudo code:

    - name: my command
      command: echo stuff
      when: &quot;if {{ ansible_hostname }} not in {{ ansible_current_groups }}&quot;

How should I do this?

Run task only if host does not belong to a group

Is it possible to run ansible playbook, which looks like this (it is an example from this site: http://docs.ansible.com/playbooks_roles.html):

    - name: this is a play at the top level of a file
      hosts: all
      remote_user: root
      tasks:
      - name: say hi
        tags: foo
        shell: echo &quot;hi...&quot;

    - include: load_balancers.yml
    - include: webservers.yml
    - include: dbservers.yml

in multithread mode?

I want to run three &quot;includes&quot; in the same time (it is deploying to different hosts anyway), like in this diagram:

http://www.gliffy.com/go/publish/5267618

Is it possible?

Ansible: deploy on multiple hosts in the same time

I am planning to execute a shell script on a remote server using Ansible playbook.

blank test.sh file:

    touch test.sh

Playbook:

    ---
    - name: Transfer and execute a script.
      hosts: server
      user: test_user
      sudo: yes
      tasks:
         - name: Transfer the script
           copy: src=test.sh dest=/home/test_user mode=0777
  
         - name: Execute the script
           local_action: command sudo sh /home/test_user/test.sh
 
When I run the playbook, the transfer successfully occurs but the script is not executed.
