 +**PROFILES**: every setting we apply to a vip is some kind of profile.\\
 +To deploy changes (profiles in this case), we can follow this process:\\
 +  - 
 +  - Use UI in CP02DEVLB01 to create profile.
 +  - Log into tmos and pull the command defining that profile. We will use this to automate it in Ansible:
 +  - we can use data ports for sync/heartbeat
 +
 +  (tmos)# list ltm profile client-ssl bondticker_wildcard one-line

 +
 +Redirection is done via an irule. (MKTX_http_to_https_redirect)

 +**__ANSIBLE__**
 +General scheme of folders is as follows:
 +
 +  * inventory --- where host information host specific variable 
 +  * input --- input information where all application specific variables are stored
 +  * playbooks --- what you actually put together
 +  * templates --- jinja2 file
 +  * roles -- function that groups together tasks into one module ...

 +BONDTICKER 
 +adding a pool ,  adding a server to a pool
 +
 +template_f5_bondticker_pools.yml  # this is the playbook. PLAYBOOK geneartes the results in the input file and 
 +pool-vars-template.j2   # for any vip. generates the bindings 
 +inputs/pools_template_bondticker.yml
 +
 +The results are created in input folder (as defined in the playbook. see dest: "../inputs/pools_bondticker_{{item.key}}.yml" )
 +Validate this input filr manually. Some of the entries will have to be commented out. In this case (F5). This file is FED IN TO THE API
 +input filer: lists (3) with dictionaries.
 +
 +then role takes the data from the input file and applied the API. Check the role to see how the api is called.
 +playbook/f5_pool_bt_dvi.yml  # <<< this is the one really applying it . dvi # dev integration

 +----
 +
 +with variable in the ansible invocation 
 +
 +f5_pool_vip_bondticker.yml
 +
 +
 +---- 
 +playbook naming convention
 +anything with L7 deals with the policy. assign is assigning to the vip.
 +
 +f5_pool : to create node, build pool and make binding
 +
 +f5_vip : to create a virtual server
