Saltstack/Jinja: How to remove the u' prefix from a list of strings

This is the salt config.sls

{% set testval = ["172.16.49.169:5044", "172.16.51.156:5044"] %}

filebeat_config:
  file.managed:
    - name: /etc/filebeat/filebeat.yml
    - source: salt://filebeat/files/filebeat.yml.tmpl
    - template: jinja
    - user: root
    - mode: 600
    - context:
      logstash_hosts: {{ testval }}

When rendered, the host entry looks like:

hosts: [u'172.16.49.169:5044', u'172.16.51.156:5044']

How do I remove the u' before each string?

I have tried {{ testval|tojson }}, {{ testval|json }} and - encoding: ascii/utf-8

Solution

  • The tojson option needs to be in tmpl file, not config.sls

    filebeat.yml.tmpl

    output.logstash:
  hosts: {{ testval|tojson }}
  loadbalance: True
  index: filebeat
