15. WHAT IS DEVOPS?
SOFTWARE LIFECYCLE COLLABORATION
DevOps is a set of practices that automates the processes between
software development and IT teams, in order that they can build, test,
and release software faster and more reliably.
DevOps is the offspring of agile software development – born from
the need to keep up with the increased software velocity and
throughput agile methods.

26. TOOLS

27. DOCKER
GET EVERYTHING DONE FASTER
Docker is a tool designed to make it easier to
create, deploy, and run applications by using
containers. Containers allow to package up an
application with all of the parts it needs and ship
it all out as one package.
Thanks to the container we can rest assured
that the application will run on any other Linux
machine regardless of any customized settings.

32. ANSIBLE

33. ANSIBLE
AUTOMATION
Ansible is an IT automation engine that
automates cloud provisioning, configuration
management, application deployment, intra-
service orchestration, and many other IT needs.
Ansible works by connecting to your nodes and
pushing out "Ansible modules" to them. These
modules are written to be resource models of
the desired state of the system.

34. ANSIBLE
WHY
Agentless
No configuration on nodes
SSH Connection (Public Key)
YAML Syntax
Open Source Project (GitHub)
Lightweight (no daemon)
Written in Python
Active Community

35. ANSIBLE
WHAT

Resources Provisioning
Nodes configuration from scratch
Updates / Upgrades
Application Deployment
Continuous Delivery
And more...

36. ANSIBLE
HOW IT WORKS
Install Ansible in your Mac or Linux system or
use a Docker container.

44. GITLAB
DEV+OPS AUTOMATION TOOL
GitLab is the first single application for the entire
DevOps lifecycle. Only GitLab enables
Concurrent DevOps, unlocking organizations
from the constraints of the toolchain.
GitLab provides unmatched visibility, higher
levels of efficiency, and comprehensive
governance. This makes the software lifecycle
200% faster, radically improving the speed of
business.

47. GITLAB RUNNER
PIPELINE AUTOMATION
GitLab runner is a build instance which is used to
run the jobs over multiple machines and send the
results to GitLab and which can be placed on
separate users, servers and local machine.
You can register the runner as shared or
dedicated executor.

50. CONTINUOUS INTEGRATION
REDUCE CODING ERRORS
Continuous Integration (CI) is a development
practice that requires developers to integrate
code into a shared repository several times a
day. Each check-in is then verified by an
automated build, allowing teams to detect
problems early.
By integrating regularly, you can detect errors
quickly, and locate them more easily.

51. CONTINUOUS DEPLOYMENT
IMPROVING PRODUCT TIME TO MARKET
Continuous deployment (CD) is a strategy
for software releases wherein any code commit
that passes the automated testing phase is
automatically released into the production
environment, making changes that are visible to
the application users.

53. GITLAB CI/CD
HOW IT WORKS
GitLab CI/CD is a web application with an API
that stores its state in a database. It manages
projects/builds and provides a nice user
interface, besides all the features of GitLab.
GitLab Runner is an application which processes
builds. It can be deployed separately and works
with GitLab CI/CD through an API.
