ansible wget then exec scripts => get_url equivale

问题:

I always wonder what is the good way to replace the following shell tasks using the "ansible way" (with get_url, etc.):

- name: Install oh-my-zsh
  shell: wget -qO - https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | bash -

or

- name: Install nodesource repo
  shell: curl -sL https://deb.nodesource.com/setup_5.x | bash -

This worked for me:

  - name: Download zsh installer
    get_url: url=https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh dest=/tmp/zsh-installer.sh

  - name: Execute the zsh-installer.sh
    shell: /tmp/zsh-installer.sh

  - name: Remove the zsh-installer.sh
    file: path=/tmp/zsh-installer.sh state=absent

@RaviTezu solution doesn't work because the file/script that you wish to execute must be on the machine where you execute your play/role.

As per the documentation here

The local script at path will be transferred to the remote node and then executed.

So one way to do it is by downloading the file locally and using a task like below:

- name: execute the script.sh
  script: /local/path/to/script.sh

Or you can do this:

- name: download setup_5.x file to tmp dir
  get_url:
    url: https://deb.nodesource.com/setup_5.x
    dest: /tmp/
    mode: 0755

- name: execute setup_5.x script
  shell: setup_5.x
  args:
    chdir: /tmp/

I would go for the first method if you are uploading your own script, the second method is more useful in your case because the script might gets updated in time so you are sure each time you execute it it uses the latest script.

For me, the following statement worked:

 - name: "Execute Script"
   shell: curl -sL https://rpm.nodesource.com/setup_6.x | bash -

May be this basic example can help you to start:

---
- name: Installing Zsh and git
  apt: pkg=zsh,git state=latest
  register: installation

- name: Backing up existing ~/.zshrc
  shell: if [ -f ~/.zshrc ]; then mv ~/.zshrc{,.orig}; fi
  when: installation|success
  sudo: no

- name: Cloning  oh-my-zsh
  git:
    repo=https://github.com/robbyrussell/oh-my-zsh
    dest=~/.oh-my-zsh
  when: installation|success
  register: cloning
  sudo: no

- name: Creating new ~/.zshrc
  copy:
    src=~/.oh-my-zsh/templates/zshrc.zsh-template
    dest=~/.zshrc
  when: cloning|success
  sudo: no

Note the: "force=yes", which will always download the script, overriding the old one. Also note the "changed_when", which you can refine per your case.

  - name: 'Download {{ helm.install_script_url }}'
    environment:
      http_proxy:  '{{proxy_env.http_proxy | default ("") }}'
      https_proxy: '{{proxy_env.https_proxy | default ("") }}'
      no_proxy:    '{{proxy_env.no_proxy | default ("") }}'
    get_url: url={{ helm.install_script_url | default ("") }} dest=/tmp/helm_install_script force=yes mode="0755"
    when: helm.install_script_url is defined
    tags:
    - helm_x

  - name: Run {{ helm.install_script_url }}
    environment:
      http_proxy:  '{{proxy_env.http_proxy | default ("") }}'
      https_proxy: '{{proxy_env.https_proxy | default ("") }}'
      no_proxy:    '{{proxy_env.no_proxy | default ("") }}'
    command: "/tmp/helm_install_script"
    register: command_result
    changed_when: "'is up-to-date' not in command_result.stdout"
    when: helm.install_script_url is defined
    args:
      chdir: /tmp/
    tags:
    - helm_x

Consider using the get_url or uri module rather than running curl.

For example:

- name: Download setup_8.x script
  get_url: url=https://deb.nodesource.com/setup_8.x dest=/opt mode=755
- name: Setup Node.js
  command: /opt/setup_8.x
- name: Install Node.js (JavaScript run-time environment)
  apt: name=nodejs state=present
