 - We're going to `ignore errors` and even if playbook failed it's going to execute

+### Demo: Error Handling – Block Groups
+Block groups and rescues - like a try and catch.
+```
+---
+- hosts: labservers
+  tasks:
+    - name: get file
+      block:
+        - get_url:
+            url: "http://innaghiyev3c/index.html"
+            dest: "/tmp/index_file"
+      rescue:
+        - debug: msg="The file doesn't exists!"
+      always:
+        - debug: msg="Play done!"
+```
+  
+- `rescue` - that part of block will run if playbook run failed
+- `always` - that part of block will run any time. No matter playbook run fails or not. 
+  
+Here how rescue block is working:

+### Selectively Run Specific Tasks In Playbooks Using Tags
+How Ansible uses tags
+- You can have several deployments in your cookbook. Like database and application deployment
+- By using tags we can deploy only application stage or only database stage
+  
+```
+---
+- hosts: web
+  become: yes
+  tasks:
+  - name: deploy app binary
+    copy:
+      src: /home/cloud_user/apps/hello
+      dest: /var/www/html/hello
+    tags:
+      - webdeploy
+- hosts: db
+  become: yes
+  tasks:
+  - name: deploy db script
+    copy:
+      src: /home/cloud_user/apps/script.sql
+      dest: /opt/deb/scripts/script.sql
+    tags:
+      - dbdeploy
+```
+
+- `ansible-playbook tags_playbook.yml` - running playbook without tags
+- `ansible-playbook tags_playbook.yml --tags webdeploy` - running playbook only for `webdeploy` part
+- `ansible-playbook tags_playbook.yml --tags dbdeploy` - running playbook only for `dbdeploy` part
