what is the best way to use ansible for reading hosts ip address and use it later? -


i have 3 hosts, first 1 controller , other 2 used lamp. have write playbook in ansible finds ip address of each host , use later in same ansible playbook settings. want save in variable , use later.

here how read it

--- - hosts: localhost   connection: local   tasks:     - debug: var=ansible_all_ipv4_addresses     - debug: var=ansible_default_ipv4.address

this want use it:

--- - hosts: laborator   become: yes   become_user: root    tasks:     - name: create directory php page       file:         path: /var/www/html/virtual1         state: directory         owner: apache         group: apache         mode: 0775         recurse: yes     - name: ensure file exists       copy:         content: ""         dest: /var/www/html/virtual1/info.php         owner: apache         group: apache         force: no         mode: 0555     - name: add string new file       lineinfile: dest=/var/www/html/virtual1/info.php                 regexp='^'                 line='<?php phpinfo(); ?>'                 state=present     - name: change file permissions       file:         path: /var/www/virtual1/info.php         owner: apache         group: apache         mode: 0644     - name: set kernel parameters       lineinfile:         path: /etc/hosts         regexp: '^'         line: '192.168.115.198 laborator1'  <<<-here*****

you can see line need ip. i'm new ansible second day, please point me right direction.

thank you.

if use gather_fact: yes in play (it's default value unless disabled in on gathering config), able access ansible_default_ipv4.address value current host.
if want access host (on there gather_fact), can use hostvars[inventory_hostname].ansible_default_ipv4.address.
there ansible_ethx.ipv4.address each interface.

you can see available variables using setup module

ansible -m setup

variables doc: http://docs.ansible.com/ansible/latest/playbooks_variables.html#magic-variables-and-how-to-access-information-about-other-hosts

in case, be:

- name: put ip of each laborator hosts in /etc/hosts   lineinfile:     path: /etc/hosts     regexp: '^'     line: '{{ hostvars[item].ansible_default_ipv4.address }} {{ hostvars[item].ansible_hostname }}'   with_items: '{{ groups.laborator }}'

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
