A recurring theme that's in my ansible playbooks is that I often must execute a command with sudo privileges (sudo: yes
) because I'd like to do it for a certain user. Ideally I'd much rather use sudo to switch to that user and execute the commands normally. Because then I won't have to do my usual post commands clean up such as chowning directories. Here's a snippet from one of my playbooks:
- name: checkout repo
git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
sudo: yes
- name: change perms
file: dest={{ dst }} state=directory mode=0755 owner=some_user
sudo: yes
Ideally I could run commands or sets of commands as a different user even if it requires sudo to su to that user.

In Ansible 2.x, you can use the block
for group of tasks:
- block:
- name: checkout repo
git:
repo: https://github.com/some/repo.git
version: master
dest: "{{ dst }}"
- name: change perms
file:
dest: "{{ dst }}"
state: directory
mode: 0755
owner: some_user
become: yes
become_user: some user
You can specify become_method
to override the default method set in ansible.cfg
(if any), and which can be set to one of sudo, su, pbrun, pfexec, doas, dzdo, ksu
.
- name: I am confused
command: 'whoami'
become: true
become_method: su
become_user: some_user
register: myidentity
- name: my secret identity
debug:
msg: '{{ myidentity.stdout }}'
Should display
TASK [my-task : my secret identity] ************************************************************
ok: [my_ansible_server] => {
"msg": "some_user"
}
In Ansible >1.4 you can actually specify a remote user at the task level which should allow you to login as that user and execute that command without resorting to sudo. If you can't login as that user then the sudo_user solution will work too.
---
- hosts: webservers
remote_user: root
tasks:
- name: test connection
ping:
remote_user: yourname
See http://docs.ansible.com/playbooks_intro.html#hosts-and-users
A solution is to use the include
statement with remote_user
var (describe there : http://docs.ansible.com/playbooks_roles.html) but it has to be done at playbook instead of task level.
