Ansible playbook 抱怨引号

Question

I'm using Ubuntu 16 with Ansible 2.2.1.0.

I am trying to install docker-compose with the following playbook:

  - name: Install Docker Compose.
      shell: "curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose"
      file:
         dest=/usr/local/bin/docker-compose mode=x
         src=/usr/local/bin/docker-compose  dest=/usr/bin/docker-compose state=link

I get this error:

  - name: Install Docker Compose.
      shell: "curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose"
           ^ here
This one looks easy to fix.  It seems that there is a value started
with a quote, and the YAML parser is expecting to see the line ended
with the same kind of quote.  For instance:

    when: "ok" in result.stdout

Could be written as:

   when: '"ok" in result.stdout'

What is the problem? I have starting and ending quotes.

shell module hasn't file parameter and shell and name should be on same column that why you got the error and also use a double quote for URL and not full shell command:

   - name: Install Docker Compose.
     shell: curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose"

You can use the get_url module to download the file to the destination and set permission. And I highly recommend using Ansible role that presented by contributors on the ansible galaxy and not to reinvited wheels!
