 ====== Ansible ======
+===== Základní konfigurace =====
+==== Vypnutí cowsay (kravičky): ====
 <code bash>
-# Vypnutí "kraviček":
 export ANSIBLE_NOCOWS=1
 </code>
-Seznam hostů:
+nebo
+V souboru /etc/ansible/ansible.cfg odkomentovat:
+<code|bash>
+nocows = 1
+</code>
+==== Host key checking ====
+Vypnutí ověřování klíče ssh serveru/hosta. Typicky po reinstalaci se změní klíč a ssh hlásí chybu při připojení, že klíč se změnil.
+V souboru /etc/ansible/ansible.cfg:
+<code>
+[defaults]
+host_key_checking = False
+</code>
+nebo
+<code|bash>
+export ANSIBLE_HOST_KEY_CHECKING=False
+</code>
+===== Inventory =====
   * /etc/ansible/hosts
+===== Ad-Hoc příkazy =====
+Předpokladem je funkční SSH spojení se všemi prvky s ověřováním klíčem. Příkazy se spouští pod běžným uživatelským účtem (tedy ne pod rootem).
+<code|bash>
+# test spojení na všechny prvky z inventory souboru
+ansible all -m ping
+# Spuštění příkazu na všech prvcích jako sudo
+(ansible all -u kaplan --sudo --ask-sudo-pass -a "/bin/echo hello") starsi zpusob
+ansible all -u kaplan -become -K -m ping
