//automation for everyone … what’s new in Tower 3.1?

//ansible tower

CONTROL

SIMPLE POWERFUL AGENTLESS

KNOWLEDGE DELEGATION

TOWER EXPANDS AUTOMATION TO YOUR ENTERPRISE.

AT ANSIBLE’S CORE IS AN OPEN-SOURCE AUTOMATION ENGINE.

Scheduled andcentralized jobs

Visibility and compliance

Role-based access and self-service

Everyone speaks the same language

Designed for Multi-tier deployments

Predictable, reliable,and secure

//what is ansible tower?

Ansible tower is an enterprise framework for controlling, securing and managing your Ansible automation – with a UI and RESTful API.

• Role-based access control keeps environments secure, and teams efficient.

• Non-privileged users can safely deploy entire applications with push-button deployment access.

• All Ansible automations are centrally logged, ensuring complete auditability and compliance.

//control your ansible deployment

SITUATIONAL AWARENESS IS THE KEY TO DEVOPS

● Dashboard and real-time automation updates

● Integrated RBAC with credential management

● Job scheduling

● Graphical inventory management

● Built-in notifications to keep teams informed

● Stabilized API to plumb into existing tooling and processes

● Model entire processes with new Workflows

//tower workflows

MIX AND RE-USE AUTOMATIONS WITHOUT WRITING A PLAYBOOK

● Combine any number of Playbooks into a Workflow

● Delegate access just like any other Tower automation

● Launchable with customizable parameters

● Easily build in-app workflows

Provision Configure Deploy Scale

Build Test Promote Verify Deploy

//delegation

EMPOWER YOUR TEAMS INSIDE AND OUTSIDE OF OPERATIONS

● Connect to your LDAP, AD, SAML and other directories

● Full role-based access control engine

● Store credentials for use without exposure

● Enable users to automate without previous Ansible knowledge

● Find relevant information more quickly with new Smart Search

● Simple surveys configure automation at run-time

● REST API allows integration into your existing processes and tools

● Add capacity with new Tower Clusters

//tower clusters

ADD TOWER CAPACITY AND REDUNDANCY WITH EASE

● Add new Tower nodes to scale out Tower job capacity

● Tower node fails? No problem

● Individual Tower jobs will run on any node with available capacity

○ Jobs are not spanned across multiple Tower nodes

● Cluster stays in sync with in-Tower configuration

//enterprise log integration

ANALYZE YOUR AUTOMATION RESULTS

● Log all Tower activity to central enterprise logging

● Cross-reference automation with events and application logs

● Use Tower’s API to perform remediation if needed

● Support for:

○ Elastic

○ Splunk

○ Sumologic

○ Loggly

○ Custom (Via WebHook/RESTful API)

//automate everything

//demo

//ansible and windows

● Linux○ Ansible manages Linux/Unix machines using SSH

● Windows○ Uses PowerShell remoting rather than SSH○ Ansible still runs from a Linux control machine and uses○ WinRM python module to talk to the windows host

//how it works

● Gather facts on Windows hosts● Install and uninstall MSIs● Enable and disable Windows Features● Start, stop, and manage Windows services● Create and manage local users and groups● Manage Windows packages via the Chocolatey

package manager● Manage and install Windows updates● Fetch files from remote sites● Push and execute PowerShell scripts

//native windows support

# Execute a command in the remote shell; stdout outputs to the specified file

---- name: Run win_shell hosts: all gather_facts: false tasks: - name: Run some script win_shell: C:\somescript.ps1 >> c:\somelog.txt

//win_shell module

● fetch● raw● script● slurp● template● add_host● assert

//ansible core modules for windows

● pause● set_fact● debug● fail● group_by● include_vars● meta

---# This playbook tests the script module on Windows hosts- name: Run powershell script hosts: all gather_facts: false tasks: - name: Run powershell script script: files/helloworld.ps1

//script module

● Active Directory○ Kerberos is the preferred option when using AD○ Requirement to install ‘python-kerberos’ module on the

control host

# yum -y install python-devel krb5-devel krb5-libs krb5-workstation

//authentication

● Configure Kerberos# vi /etc/krb5.conf

[realms]

MY.DOMAIN.COM = { kdc = domain-controller1.my.domain.com kdc = domain-controller2.my.domain.com }

[domain_realm] .my.domain.com = MY.DOMAIN.COM

//authentication

● runas ○ There is upcoming support to execute actions as the

administrator with Windows ‘runas’○ Presently, connect and automate Windows using local

or domain users

//coming soon
