Ansible template loop with iteritems

[Ciobancai Vlad]

Hi,

I would like to create dynamically some configuration files (the configs are used by tomcat) using a template  based some variables from group_vars

Below is what I have

- group_vars/test.yml

file: 

    - log4j

    - config

log4j:

    log4j.rootCategory: INFO

    log4j.appender.SYSLOG: org.apache.log4j.net.SyslogAppender

    log4j.appender.SYSLOG.syslogHost: testhost

jira:

    jira.soap.url: https://hostname

    jira.login.username: test

    jira.login.password: test14

- roles/test/main.yml

   - name: 'Configure the application properties'

        template:

          src: "template.j2"

          dest: "/tmp/{{ item }}.properties"

          owner: build

          group: build

          backup: yes

        with_items: "{{ file }}"

- roles/test/template/template.j2

{% for key, value in {{ item.iteritems() }} %}

   {{ key }}= {{ value }}

{% endfor %} 

So I would like to iterate every "file" and to create the files

I'm receiving "msg": "AnsibleError: template error while templating string: expected token ':', got '}'. String: ## File managed by ansible ##\n\n{{ item }}\n{{ propertyfiles }}\n\n{% for i in {{ propertyfiles }} %}\n {% for key, value in i.items() %}\n {{ key }}= {{ value }}\n {% endfor %} \n{% endfor %} \n"}

You are already in jinja template mode between {% %} so you can't use {{
}} there.

{% for key, value in item.iteritems() %}

I'm receiving the folllowing error "msg": "AnsibleUndefinedVariable: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'iteritems'"}

I didn't look at what you where trying to do I just saw the syntax
error.

But I see what you are trying to do, I'm not sure but maybe this work

{% for key, value in vars[item].iteritems() %}

Works, thank you for your help.

I have another question, after I applied the changes, now every line in the files contains a new empty line. It is possible to be removed ?

{% for key, value in vars[item].iteritems()| sort %} 

{{ key }}= {{ value }}

{% endfor %} 

log4j.appender.MAIN_APPENDER= org.apache.log4j.RollingFileAppender

log4j.appender.MAIN_APPENDER.File= /tmp/log4j.log

log4j.appender.MAIN_APPENDER.MaxBackupIndex= 5

I don't know why since you shouldn't unless you input contain extra
whitespaces.

You can try to use {%- and/or -%} to remove whitespaces, more on the
subject here
