-# My useful ansible playbooks
+# Ansible centralized keys management
 
-Security management:
+Dicts in parent group merges with dicts in child groups. 
 
-- [Centralized SSH keys management](https://git.blindage.org/21h/ansible-library/src/branch/centralized-keys)
+Warning! Playbook will delete all public keys in root's ```.ssh/authorized_keys``` file and setup own **super** key, only after this public keys in group_vars and host_vars will be added into assigned users ```.ssh/authorized_keys``` files.
 
-System and monitoring:
+**Security issue!** You need to generate your own super key! Run ```ssh-keygen -f superkey``` and replace keys in ```secret/``` directory.
 
-- [Create systemd and upstart scripts](https://git.blindage.org/21h/ansible-library/src/branch/sys-systemd-and-upstart)
+Infrastructure:
 
-Web deployment:
+```
+--[ hetzner ]--\
+               |- hetzner-balancers
+               \- hetzner-nodes
+```
 
-- [PHP 7.1 FPM + Nginx](https://git.blindage.org/21h/ansible-library/src/branch/web-nginx-php-fpm7.1)
+All servers will be available to the administrator and assistant, servers must have own internal key for files copying. Configuring parent ```hetzner```group:
+
+```
+    access_list:
+      admin: { keypath: "../keys/admin.pub", username: "root" }
+      techguy: { keypath: "../keys/techguy.pub", username: "root" }
+      interserver: { keypath: "../keys/interserver.pub", username: "root" }
+
+    secret_list:
+      interserver: { keypath: "../keys/interserver.pem", username: "root" }
+```
+
+You want to make additional access to all nodes for developer guy. Configuring child ```hetzner-nodes``` group:
+
+```
+    access_list:
+      developer: { keypath: "../keys/developer.pub", username: "dev" }
+```
+
+No need to make additional config for ```hetzner-balancers``` because access list will be inherited, only admins accessible.
