ansible-playbook

I'm using Ansible with Jinja2 templates, and this is a scenario that I can't find a solution for in Ansible's documentation or googling around for Jinja2 examples. Here's the logic that I want to achieve in Ansible: if {{ existing_ansible_var }} == "string1" new_ansible_var = "a" else if {{ existing_ansible_var }} == "string2" new_ansible_var = "b" <...> else new_ansible_var = "" I could probably do this by combining several techniques, the variable assignment from here: Set variable in jinja , the conditional comparison here: http://jinja.pocoo.org/docs/dev/templates/#if-expression , and the

I have the following /etc/ansible/hosts: [ESNodes] isk-vsrv643 isk-vsrv644 isk-vsrv645 [PerfSetup] isk-dsrv613 isk-dsrv614 I know there is an option to run a playbook on particular hosts with -l Is there a way to run a playbook only on the PerfSetup group? Same way as you would do for hosts : -l PerfSetup 来源： https://stackoverflow.com/questions/22129422/running-an-ansible-playbook-on-a-particular-group-of-servers

I'm trying insert a line in a property file using ansible. I want to add some property if it does not exist, but not replace it if such property already exists in the file. I add to my ansible role - name: add couchbase host to properties lineinfile: dest=/database.properties regexp="^couchbase.host" line="couchbase.host=127.0.0.1" But this replaces the property value back to 127.0.0.1 if it exists already in the file. What I'm doing wrong? udondan The lineinfile module does what it's supposed to: It ensures the line as defined in line is present in the file and the line is identified by your

I've created an Ansible playbook that creates a cloud instance and then installs some programs on the instance. I want to run this playbook multiple times (without using a bash script). Is it possible to use a loop to loop over those two tasks together (I.E. One loop for two tasks?). All I've been able to find so far is one loop for each individual task No that's currently not possible. with_items used to work with the include statement in previous versions of Ansible but was unfortunately dropped. Though it will be brought back in Ansible 2.0, see slide 14/15 of What's New in v2 - AnsibleFest

How can I pass yaml array to --extra-vars in Ansible playbook. Ansible documentation does not declares its syntax nor I can find that on any internet resource. I mean if I have a playbook: --- - hosts: {{hostName}} - remote_user: admin ... Then I should call my playbook like ansible-playbook DeployWar.yml --extra-vars="hostName=tomcat-webApp" But I want to run this playbook on two servers say tomcat-webApp and tomcat-all , and I want to control it from out side i.e. using --extra-vars . What I have tried to do is: ansible-playbook DeployWar.yml --extra-vars="hostName=[tomcat-webApp, tomcat-all

I am pulling JSON via the URI module and want to write the received content out to a file. I am able to get the content and output it to the debugger so I know the content has been received, but I do not know the best practice for writing files. You could use the copy module, with the content parameter: - copy: content="{{ your_json_feed }}" dest=/path/to/destination/file The docs here: copy module Unless you are writing very small files, you should probably use templates . Example: - name: copy upstart script template: src: myCompany-service.conf.j2 dest: "/etc/init/myCompany-service.conf"

Sometimes I need to test some jinja2 templates that I use in my ansible roles. What is the simplest way for doing this? For example, I have a template (test.j2): {% if users is defined and users %} {% for user in users %}{{ user }} {% endfor %} {% endif %} and vars (in group_vars/all): --- users: - Mike - Smith - Klara - Alex At this time exists 4 different variants: 1_Online (using https://cryptic-cliffs-32040.herokuapp.com/ ) Based on jinja2-live-parser code. 2_Interactive (using python and library jinja2, PyYaml) import yaml from jinja2 import Template >>> template = Template(""" ... {% if

what I'm trying to accomplish is to run commands inside of a Docker container that has already been created on a Digital Ocean Ubuntu/Docker Droplet using Ansible. Can't seem to find anything on this, or I'm majorly missing something. This is my Ansible task in my play book. I'm very new to Ansible so any advice or wisdom would be greatly appreciated. - name: Test Deploy hosts: [my-cluster-of-servers] tasks: - name: Go Into Docker Container And Run Multiple Commands docker: name: [container-name] image: [image-ive-created-container-with-on-server] state: present command: docker exec -it
