Ansible cloudformation update stack

阅读更多关于 Ansible cloudformation update stack

I'm trying to update a cloudformation stack with just a param value that I need to change via Ansible. The stack is previously created and has about 20 input params, but I just need to update the value for one. I tried the following: - name: update cloudformation: stack_name: "{{ stack_name }}" state: present region: "{{ region }}" disable_rollback: false args: template_parameters: CreateAlarms: "{{ create_alarms }}" When I run it, the play throws an error stating that it expects values for the other template params. From the ansible documentation here http://docs.ansible.com/ansible/latest

How to remove or exclude an item in an Ansible template list?

阅读更多关于 How to remove or exclude an item in an Ansible template list?

问题 I'm writing an Ansible template that needs to produce a list of ip's in a host group, excluding the current hosts IP. I've searched around online and through the documentation but I could not find any filters that allow you to remove an item in a list. I have created the (hacky) for loop below to do this but was wondering if anyone knew a "best practice" way of filtering like this. {% set filtered_list = [] %} {% for host in groups['my_group'] if host != ansible_host %} {{ filtered_list

阅读更多关于 Ansible, set_fact using if then else statement

I am trying to set a variable in Ansible with set_fact at runtime based upon another variable. If uses first value no matter what the actual value is. Here is my code example: - name: Global_vars - get date info set_fact: jm_env: "{{lookup('env', 'Environment')}}" l_env: "{% if '{{jm_env}}==Develop' %}d{% elif '{{jm_env}}==Staging'%}s{% else %}p{% endif %}" l_env is d no matter what jm_env is set. Firstly, dictionaries in YAML are not ordered (and the syntax used by Ansible here is a YAML dictionary), so you have no guarantee Ansible would first set jm_env before proceeding to l_env -- you

阅读更多关于 ansible - delete unmanaged files from directory?

问题 I want to recursively copy over a directory and render all .j2 files in there as templates. For this I am currently using the following lines: - template: > src=/src/conf.d/{{ item }} dest=/dest/conf.d/{{ item|replace('.j2','') }} with_lines: find /src/conf.d/ -type f -printf "%P\n" Now I'm looking for a way to remove unmanaged files from this directory. For example if I remove a file/template from /src/conf.d/ I want Ansible to remove it from /dest/conf.d/ as well. Is there some way to do

Ansible: get current target host's IP address

阅读更多关于 Ansible: get current target host's IP address

How do you get the current host's IP address in a role? I know you can get the list of groups the host is a member of and the hostname of the host but I am unable to find a solution to getting the IP address. You can get the hostname by using {{inventory_hostname}} and the group by using {{group_names}} I have tried things like {{ hostvars[{{ inventory_hostname }}]['ansible_ssh_host'] }} and ip="{{ hostvars.{{ inventory_hostname }}.ansible_ssh_host }}" A list of all addresses is stored in a fact ansible_all_ipv4_addresses , a default address in ansible_default_ipv4.address . --- - hosts:
