Oracle Week 2017: Docker Concepts for Oracle/MySQL DBAs and DevOps (slides)

Oracle Week in Israel is a reason for celebration. Every year (and for the past 24 years), between a 1500 and 2000 Oracle professional are gathered for a 5 days conference on Oracle related educational topics. Each day is a full-day seminar on a specific topic – 9am to 4:30pm talking about something related to Oracle technologies. This year, I had 4 full-day back-to-back seminars – which is way more than the average speaker. Some of the sessions were on topics I spoke on last year and the year before (SQL and PL/SQL), but some were completely new.

This seminar was about Docker Containers: introduction and how to use them combined with Oracle RDBMs and MySQL.

Before the conference, I wasn’t totally sure if it’s going to open. The minimum requirement to open a session is around 10-12 people and the organizer warned me that the chances are slim – but I was sure this is a “hot” topic and submitted this topic anyway.  I was surprised to see that over 30 people registered to the session – and stayed just until the end. The feedbacks were also great (4.95 out of 5) so thank you guys! 🙂

Docker Containers

Docker is an open source software development platform. Its main benefit is to package applications in container, a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings. The container isolates the software from its surroundings, for example differences between development and staging environments, and helps reduce conflicts between teams running different software on the same infrastructure. That means that we can create and maintain a simple deployable “boxes” of “application” (or micro-services) – including code and databases.

One of the cool things you can do with it is to deploy a full-scale Oracle RDBMS (or MySQL or other NoSQL solutions) in a matter of minutes. No need to install OS, pre-requirements or even create an instance – it’s all self contained in the container itself.

In this session we learned how to use Docker, how to use it with databases and why it might be a good idea to combine them. We even had an open discussion about ideas how to implement this in different environment.

This is the Agenda for the session:
Docker overview – why do we even need containers?
Installing Docker and getting started
Images and Containers
Docker Networks
Docker Storage and Volumes
Oracle and Docker
Docker tools, GUI and Swarm
