I'm trying to change rsyslog logrotate configuration using Ansible, but when running task:
- name: Setup logrotate.d scripts
template:
src: logrotate.d.j2
dest: "{{ logrotate_conf_dir }}{{ item.name }}"
with_items: "{{ logrotate_scripts }}"
when: logrotate_scripts is defined
Which is adding this kind of configuration:
logrotate_scripts:
- name: rsyslog
path:
- "/var/log/syslog.log"
- "/var/log/daemon.log"
- "/var/log/kern.log"
- "/var/log/mail.log"
- "/var/log/user.log"
- "/var/log/lpr.log"
- "/var/log/auth.log"
- "/var/log/cron.log"
- "/var/log/debug"
- "/var/log/messages"
options:
- daily
- missingok
- maxsize 100M
- rotate 14
- compress
- compresscmd /bin/bzip2
- compressoptions -4
- compressext .bz2
- notifempty
I get this wrong format:
['/var/log/syslog.log', '/var/log/daemon.log', '/var/log/kern.log', '/var/log/mail.log', '/var/log/user.log', '/var/log/lpr.log', '/var/log/auth.log', '/var/log/cron.log', '/var/log/debug', '/var/log/messages'] {
daily
missingok
maxsize 100M
rotate 14
compress
compresscmd /bin/bzip2
compressoptions -4
compressext .bz2
notifempty
}
This is template I used for all my logrotate scripts (nginx, php and so on), but is not working properly for rsyslog.
{{ item.path }} {
{% if item.options is defined -%}
{% for option in item.options -%}
{{ option }}
{% endfor -%}
{% endif %}
{%- if item.scripts is defined -%}
{%- for name, script in item.scripts.iteritems() -%}
{{ name }}
{{ script }}
endscript
{% endfor -%}
{% endif -%}
}
How should I properly pass list of paths in order to get this effect?
/var/log/daemon.log
/var/log/kern.log
/var/log/auth.log
/var/log/user.log
/var/log/lpr.log
/var/log/cron.log
/var/log/debug
/var/log/messages
{
daily
missingok
maxsize 100M
rotate 14
compress
compresscmd /bin/bzip2
compressoptions -4
compressext .bz2
notifempty
}
You didn't share your template file but you probably want something like this in there:
{% for path in item.path %}
path
{% endfor %}
to get your list of paths.
Unless you are editing multiple files it seems wrong to use with_items like this. It is probably better to use lineinfile to customise the standard logrotate configuration with your settings.

I want to generate a list of dictionaries through the loop. I came across that we can use with_sequence to generate the integer sequences in ansible. I am getting the following error:
The offending line appears to be:
- { "dir": "{{ mat_cleaner_input_file_path_flow }}/{{ item }}" }
with_sequence: start=0 end={{ http_range }}
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
My config.j2:
{{ cleaner_config | to_nice_yaml(indent=2) }}
My task.yml:
---
- name: Test dictionaries playbook
hosts: localhost
connection: local
vars:
mat_cleaner_input_file_path_flow: "/var/opt/miq/sftp/edr-flow"
mat_cleaner_input_file_path_http: "/var/opt/miq/sftp/edr-http"
mat_cleaner_input_retention_period: 21600
http_range: 5
cleaner_config:
- { "dir": "{{ mat_cleaner_input_file_path_flow }}/{{ item }}" }
with_sequence: start=0 end={{ http_range }}
tasks:
- name: Set Cleaner Config
template:
src: /home/osboxes/CleanerConfig/cleaner.config.j2
dest: /home/osboxes/CleanerConfig/output
delegate_to: localhost
with_items: cleaner_config
I want the final output file to be:
dir: /var/opt/miq/sftp/edr-flow/0
dir: /var/opt/miq/sftp/edr-flow/1
dir: /var/opt/miq/sftp/edr-flow/2
The format of the output file you want is text. It's not a list. You can create it by Jinja, e.g.
mat_cleaner_input_file_path_flow: "/var/opt/miq/sftp/edr-flow"
http_range: 3
cleaner_config: |
{% for i in range(http_range) %}
{{ mat_cleaner_input_file_path_flow }}/{{ i }}
{% endfor %}
gives
cleaner_config: |-
/var/opt/miq/sftp/edr-flow/0
/var/opt/miq/sftp/edr-flow/1
/var/opt/miq/sftp/edr-flow/2
Then, because it's not a list, you don't have to use to_nice_yaml in the template. Use indent instead if you want to indent the lines, e.g.
shell> cat cleaner.config.j2
{{ cleaner_config|indent(2) }}
- template:
src: cleaner.config.j2
dest: output
gives
shell> cat output
/var/opt/miq/sftp/edr-flow/0
/var/opt/miq/sftp/edr-flow/1
/var/opt/miq/sftp/edr-flow/2
Under normal circumstances, you would simplify the code, omit the cleaner_config variable, and put the Jinja iteration into the template, e.g.
mat_cleaner_input_file_path_flow: "/var/opt/miq/sftp/edr-flow"
http_range: 3
shell> cat cleaner.config.j2
{% for i in range(http_range) %}
{{ mat_cleaner_input_file_path_flow }}/{{ i }}
{% endfor %}
If you want to use a list
mat_cleaner_input_file_path_flow: "/var/opt/miq/sftp/edr-flow"
http_range: 3
cleaner_config_text: |
{% for i in range(http_range) %}
- {{ mat_cleaner_input_file_path_flow }}/{{ i }}
{% endfor %}
cleaner_config: "{{ cleaner_config_text|from_yaml }}
gives
cleaner_config:
- /var/opt/miq/sftp/edr-flow/0
- /var/opt/miq/sftp/edr-flow/1
- /var/opt/miq/sftp/edr-flow/2
Now you need to_nice_yaml to format the list, e.g.
shell> cat cleaner.config.j2
{{ cleaner_config|to_nice_yaml|indent(2) }}
gives
shell> cat output
- /var/opt/miq/sftp/edr-flow/0
- /var/opt/miq/sftp/edr-flow/1
- /var/opt/miq/sftp/edr-flow/2
I'm trying to create a text file which goes through the CSV file and populates variables into specific fields.
playbook.yml:
- hosts: localhost
tasks:
- name: "Reading user information"
read_csv:
path: /home/test/vlans.csv
delimiter: ','
register: vlans
- debug: var=vlans
- name: Creating VLANs configuration
template:
src: vlan.conf.j2
dest: /tmp/vlan.conf
Jinja2 Template vlan.conf.j2:
{% for item in vlans %}
!
vlan {{ item.VLAN }}
name {{ item.Description }}
vn-segment {{ item.VNI }}
interface nve1
member vni {{ item.VNI }}
{% endfor %}
and this is a test vlans.csv file:
Tenant,VRF ,VLAN,VNI,Subnet,Description,Good to go
Test,,5,20005,,LAB-Checkpoint-FW-Mgmt,Yes
Test,,208,20208,,LAB-DMZ,Yes Test,,209,20209,,LAB-CSR-MGMT,Yes
Test,10000,210,20210,192.168.12.1/28,LAB-VRF-to-FW,Yes
Prod,,761,20761,,PROD-CORE,Yes
Prod,105,840,20840,172.18.33.1/24,Backups,Yes
Prod,,841,20841,,Transport,Yes
I want to end up with file like in jinja2 template and not repeating line "interface nve 1"
In your question, interface nve1 is inside a loop. It will repeat multiple times in the resulting vlan.conf file.
Use multiple loops in the jinja template to decide what is repeated and what isn't:
{% for item in vlans.list %}
vlan {{ item.VLAN }}
name {{ item.Description }}
vn-segment {{ item.VNI }}
{% endfor %}
interface nve1
{% for item in vlans.list %}
member vni {{ item.VNI }}
{% endfor %}
Note that I've referred to vlans.list in the start of the loops instead of vlans. This is correct as per documentation, but different to the example in the question so it may need adjusting.
i´m trying to rename ethernet-interfaces on Linux. Each interface with the name enp0s* have to be eth*. First, i create udev-rules for renaming. that works fine. Secondly i have to create new configuration-files for each interface ( ' etc/sysconfig/network-scripts/ifcfg-eth* ' ). I don´t know, how to create the loop to place parameters in each interface. Can somneone help me?
Thats an extract of my playbook:
- name: Get new interface-names of the new created udev-rules
become: yes
shell: cat /etc/udev/rules.d/70-persisten-ipoib.rules.cfg | egrep -i 'eth.'
register: car
- name: Create new-ifcfg-eth* files
template:
with_items: "{{ car.stdout_lines }}"
register: cat
template: src= roles/configure_network/templates/create_ifcfg.cfg.j2 dest=/etc/sysconfig/network-scripts/ifcfg-{{ item }}
# Template: roles/configure_network/templates/create_ifcfg.cfg.j2
{% for interface in cat.results %}
NAME="eth{{ item.name }}
TYPE=Ethernet
BOOTPROTO={{item.bootproto|default('dhcp')}}
IPV4_FAILURE_FATAL=no
IPV6INIT=no
{% if item.ipaddress is defined %}
IPADDR={{item.ipaddress}}
{% endif %}
{% if item.netmask is defined %}
NETMASK={{item.netmask}}
{% endif %}
{% if item.gateway is defined %}
GATEWAY={{item.gateway}}
{% endif %}
PEERDNS=no
{% if item.dns is defined %}
DNS1={{item.dns}}
{% endif %}
ONBOOT={{item.onboot|default('yes')}}
{% endfor %}
Just fix your syntax:
- name: Create new-ifcfg-eth* files
template:
src: create_ifcfg.cfg.j2
dest: /etc/sysconfig/network-scripts/ifcfg-{{ item }}
with_items: "{{ car.stdout_lines }}"
register: cat
Remove double template call, use relative path (no need to define full path to role's own templates), use YAML syntax instead of key=value (you had spaces in them, which are not allowed).
I've spent most of the day trying to solve this problem and have thus far failed. I am building some playbooks to automate functions in Splunk, and am attempting to convert a list of hosts from an inventory group E.G.
[search_head]
1.2.3.4
5.6.7.8
My expected (desired) result from the debug output of the play should be:
https://1.2.3.4:8089, https://5.6.7.8:8089
I am attempting to complete this by running the following playbook against a running host:
---
- name: Build search head list to initialize the captain
hosts: search_head
remote_user: ansible
vars:
inventory_file: ./inventory-ec2-single-site
search_head_uri: "{{ lookup('template', './bootstrap-sh-deployer.j2') }}"
pre_tasks:
- include_vars:
dir: 'group_vars'
extensions:
- yml
- yaml
tasks:
- name: dump array
debug:
msg: "{{ search_head_uri }}"`
With the template bootstrap-sh-deployer.j2:
{%- set search_head_uri = [] %}
{% for host in groups['search_head'] %}
{%- if search_head_uri.append("https://{{ host }}:8089") %}
{%- endif %}
{%- if not loop.last %}, {% endif -%}
{%- endfor %}
However, the current play returns search_head_uri: ", " which tells me that the loop is running, but {{ host }} is not resolving.
Once you open a Jinja2 expression or a statement you should use Jinja2 syntax. You cannot nest them (i.e. you can't use {{ }} inside {% %}).
{%- if search_head_uri.append("https://" + host + ":8089") %}
This worked - Combination of the answer above to fix jinja formatting and using hostvars to get to the ansible_nodename.
{%- set search_head_uri = [] %}
{% for host in groups['search_head'] %}
{{ "https://" + hostvars[host]['ansible_nodename'] + ":8089" }}
{%- if not loop.last %}, {% endif -%}
{%- endfor %}
My playbook contains vars that are passed to a role. When I run it, I get [DEPRECATION WARNING]: Skipping task due to undefined Error, in the future this will be a fatal error..
Here's what I have:
---
- hosts: hadoopL0X
become: yes
become_method: sudo
vars:
logrotate_scripts:
- name: "{{ item }}"
with_items:
- zookeeper
- sa
path: "/var/log{{ item }}/{{ item }}.log "
options:
- daily
- rotate 3
- missingok
- compress
- notifempty
roles:
- log-rotation
...
The role is as such:
log-rotation/tasks/main.yml
---
- name: Setup logrotate.d scripts
template:
src: logrotate.d.j2
dest: "{{ logrotate_conf_dir }}{{ item }}"
with_items: "{{ logrotate_scripts }}"
...
log-rotation/defaults/main.yml
---
logrotate_conf_dir: "/etc/logrotate.d/"
logrotate_scripts: []
...
log-rotation/templates/logrotate.d.j2
# {{ ansible_managed }}
"{{ item.path }}" {
{% if item.options is defined -%}
{% for option in item.options -%}
{{ option }}
{% endfor -%}
{% endif %}
{%- if item.scripts is defined -%}
{%- for name, script in item.scripts.iteritems() -%}
{{ name }}
{{ script }}
endscript
{% endfor -%}
{% endif -%}
}
Any help would be much appreciated!
with_items can only be used with tasks, it cannot be used when defining variables, and because of that item isn't defined. It also looks like that the service variable isn't defined as well.
