Syntax for running commands with braces in them

[Ryan Groten]

I am trying to execute a task that runs the following command (which includes a number of quote, brackets, colons, etc):

command: curl -XPUT "http://localhost:9200/_cluster/settings" -d'{ "transient" : { "cluster.routing.allocation.enable" : "none" } }'

I tried escaping all the quotes and {}, but that doesn't seem to work.  

command: 'curl -XPUT "http://localhost:9200/_cluster/settings" -d\'\{ "transient" : \{ "cluster.routing.allocation.enable" : "none" \} \}''

I also tried treating the whole command as a jinja string (I think?)

command: {{ 'curl -XPUT "http://localhost:9200/_cluster/settings" -d'{ "transient" : { "cluster.routing.allocation.enable" : "none" } }'' }}

Thanks,

Ryan

I know this isn't really a direct answer to your question, but why not use the `uri` module instead?

- uri:

    url: "http://localhost:9200/_cluster/settings"

    method: PUT

    body:

      transient:

        cluster.routing.allocation.enable: "none"

    body_format: json

Should have known, there's always a module to do what I want better.  Thanks very much I'll try this out!

I ran into this problem too. If you don't happen to use the 'uri' module, it's the double quotes that need to be escaped, not the curly's...

command: curl -XPUT "http://localhost:9200/_cluster/settings" -d'{ \"transient\" : { \"cluster.routing.allocation.enable\" : \"none\" } }'

You need them for -H's too.

-H \"Content-Type: application/json\"

HTH,

I must be close, but it's not working with uri module.  Here's what I put in the role.  Setting the uri_body as a fact beforehand and using "to_json" was an attempt to get around the error I'm getting, but that doesn't help either.

- name: Set uri_body (workaround)
  set_fact:
    uri_body:
      transient:
        cluster.routing.allocation.enable: "none"

- name: Disable shard allocation to prevent es from rebalancing missing shards
  uri:

    url: "http://localhost:9200/_cluster/settings"
    method:

PUT
    body: "{{ uri_body | to_json }}"
    body_format: json

When I run it I get this:

fatal: [vm2.example.com]: FAILED! => {"changed": false, "failed": true, "module_stderr": "", "module_stdout": "Traceback (most recent call last):\r\n  File \"/tmp/ansible-tmp-1460491268.69-8119459959976/uri\", line 3363, in <module>\r\n    main()\r\n  File \"/tmp/ansible-tmp-1460491268.69-8119459959976/uri\", line 374, in main\r\n    dict_headers['Content-Type'] = 'application/json'\r\nTypeError: 'NoneType' object does not support item assignment\r\n", "msg": "MODULE FAILURE", "parsed": false}

I didn't quite follow the exact issue, but I was able to download a page with {: in file name . Below is my test

[vagrant@admin ansible]$ ansible-playbook -i hosts -u root  --tags=url -l admin base.yml

PLAY [base role] **************************************************************

GATHERING FACTS ***************************************************************
ok: [admin]

TASK: [base | get url with] ***************************************************
changed: [admin] => (item=http://localhost/hello{:.html)

PLAY RECAP ********************************************************************
admin                      : ok=2    changed=1    unreachable=0    failed=0  

[vagrant@admin ansible]$
[vagrant@admin ansible]$ cat roles/base/tasks/urltest.yml
- name : get url with
  get_url: url={{ item }} dest=/tmp
  tags: url
  with_items:
        - http://localhost/hello{:.html
[vagrant@admin ansible]$ ls /tmp/hello\{\:.html
/tmp/hello{:.html
[vagrant@admin ansible]$

Finally got it working, thanks everyone for the suggestions!  For reference here's what ended up working:

- name: Set uri endpoints
  set_fact:
    es_disable_allocation:

      transient:
        cluster.routing.allocation.enable: "none"

- name: Disable shard allocation to prevent es from rebalancing missing shards
  uri:
    url: "http://localhost:9200/_cluster/settings"
    method:

PUT
    body: "{{ es_disable_allocation|to_json }}"
