Question:
I am trying to filter out a line out of Ansible stdout_lines result. The ansible playbook task I ran was the following shell argument:
|
1 2 3 4 5 |
- name: VERIFY | Confirm that queue exists properly shell: aws sqs list-queues --region {{region}} environment: "{{ aws_cli_environment|d({}) }}" register: sqs_list |
To see the results, I followed it up with a debug:
|
1 2 3 |
- debug: msg: "{{ sqs_list.stdout_lines|list }}" |
which gives the following result during the playbook run:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
TASK [sqs : debug] ******************************************************************************************************************************************************************************************** ok: [localhost] => { "msg": [ "{", " \"QueueUrls\": [", " \"sampleurl1\",", " \"sampleurl2\",", " \"sampleurl3\",", " \"sampleurl4\",", " \"https://sampleurl5/test_sqs\"", " ]", "}" ] } |
I want ONLY the last url, “test_sqs” to appear under “msg”:, I tried the following filter but had no luck:
|
1 2 3 |
- name: VERIFY | Find SQS url command: "{{ sqs_list.stdout_lines|list }} -- formats | grep $sqs" |
Answer:
Script:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
--- - name: A simple template hosts: local connection: local gather_facts: False tasks: - name: list queue shell: aws sqs list-queues --region us-east-1 --queue-name-prefix test_sqs --query 'QueueUrls[*]' --output text register: sqs_list - debug: msg: "{{ sqs_list.stdout_lines|list }}" |
Output:
|
1 2 3 4 5 6 |
ok: [localhost] => { "msg": [ "https://queue.amazonaws.com/xxxxxxxxx/test_sqs-198O8HG46WK1Z" ] } |
You can make use of the --queue-name-prefix parameter to list only queues which is starting with name test_sqs. If there is only one queue with that name, you can use this solution.
