Salt states. If variables have some word in stdout

Question

There is a web page with a large piece of text on it.

I want to configure the state to perform a certain action if curl returns an error.

If the variable doesn't contain 'StatusDescription : OK'

How can I set up a check for a piece of text that is inside a variable

{% set seqstat = salt['cmd.run']('powershell.exe curl http://127.0.0.1:5001 -UseBasicParsing') %}

{% if seqstat is sameas '*StatusDescription : OK*'  %}

module_run:
  cmd.run:
    - name: 'powershell.exe WRITE-HOST have no Error'

{% else %}

module_run1:
  cmd.run:
    - name: 'powershell.exe WRITE-HOST have Error'

{%- endif -%}

Answer 1

I want to configure the state to perform a certain action if curl returns an error.

There is a Salt state called http which can query a URL and return the status. Using this (instead of curl) we can check for the status code(s) (200, 201, etc.), as well as matching text. Then we can use requisites to run subsequent states depending on the success/failure of the http.query.

Example:

I have added a check for status code of 200, you can omit - status: 200 if you don't care about the status code.

check-application:
  http.query:
  - name: http://127.0.0.1:5001
  - status: 200
  - match: 'StatusDescription : OK'

app-running:
  cmd.run:
  - name: 'powershell.exe WRITE-HOST have no Error'
  - require:
    - http: check-application

app-not-running:
  cmd.run:
  - name: 'powershell.exe WRITE-HOST have Error'
  - onfail:
    - http: check-application
