The document discusses DevOps goals and solutions at Softlayer including: - Reliable one-click deployments with visibility into configuration history - Isolated environments for learning without impacting others - Infrastructure contributions from any team member via code changes It proposes using Ansible for configuration management and Git for infrastructure as code. Vagrant enables local developer instances. Manual work and single points of failure should be eliminated. The document also discusses using Ansible to configure MariaDB and create a database, and how Vagrant and Virtualbox enable reproducible development environments.

1. The future of DevOps at Softlayer
● Goals
– One click reliable deployment
– Visibility into every line of configuration past and present
– Each person has their own isolated environment to learn and make
mistakes in
– Anyone on any team can contribute to the infrastructure
● Our Solutions
– Configuration management with Ansible
– Configuration as code with Ansible and Git
– Vagrant to set up local developer instances
– Anyone can make a pull request to the project since its just code.

2. Things best left in the past...
● That one person who knows the whole system and everyone
relies on. We should strive to eliminate human related single
points of failure and bottlenecks.
● Anything configured by hand. It doesn't scale. It leaves no
traces and is not reproducible. Even a single line changed by
hand is too much.
● Manual deployments. Every point in the process that requires a
human reduces reliability and causes massive bottlenecks.

3. Configuration management with Ansible
Why Ansible?
– Agentless: target systems just need SSH
– Powerful with a minimal learning curve
– Easy to understand code
Lets see a comparison with other configuration management
systems

4. Now 10,227!!

6. Lets setup MariaDB and create a database in Ansible!
- name: install mariadb
yum: name={{item}} state=latest
with_items:
- mariadb
- mariadb-server
- MySQL-python
- name: setup mariadb config
template: src=my.cnf.j2 dest=/etc/my.cnf
- name: start and enable mariadb
service: name=mariadb state=started enabled=yes
- name: create nova database
mysql_db: name=nova state=present
- name: create nova database user
mysql_user:
name: nova
host: "{{ item }}"
password: "{{ nova_mysql_password }}"
priv: nova.*:ALL
state: present
with_items:
- "%"
- localhost
- "{{openstack_mariadb_host}}"

7. Vagrant + Virtualbox
● Reproducible development environments for the masses.
● The days of worrying about stepping on others feet in a shared
development environment are over.
● Clean slate whenever you need it. A good practice is to reset your
development environment once a day. Favor destruction over
halting.
● Quick and painless delivery of vm images.
● Becomes even more useful when you have to spin up multiple
machines.
