6 Things You Should Know before Dockercon 2018 EU

Estimated Reading Time: 6 minutes
 
At Dockercon 2018 this year, you can expect 2,500+ participates, 52 breakout sessions, 11 Community Theatres, 12 workshops, over 100+ total sessions, exciting Hallway Tracks & Hands-on Labs/Trainings, paid trainings, women’s networking event, DockerPals Meetup, chance to meet Docker community experts – Docker Captains & Community Leaders, attending Ecosystem Expo… and only 3 days to accomplish it all. It’s so easy to get overwhelmed but at the same time you need to attend with the right information, so that you walk out triumphant.
 

 

 
Coming Dec 3-5 2018, I will be attending my 3rd Dockercon conference which is slated to happen in the beautiful city of Barcelona, home to the largest football stadium in all of Europe! Based on my past experience, I am here to share and walk you through the inside scoop on where to go when, what to watch out, must-see sessions, who to meet, and much more.
 

#1. UnFold & Unlock with Dockercon AB – “Dockercon 2018 Agenda Builder”

Once you get your Dockercon ID ready via Registration & Info Desk, just turn it around to unfold and unlock Dockercon Agenda for next 3 days. Very simple, isn’t it? Dockercon Agenda Builder is right in your hand.

 
 
 
Wait, I want to access it beforehand? Sure. You can find out when and where everything is happening at Dockercon with this simple Agenda Builder
 
If you’re CI-CD Enthusiast like me, you should use filters under Agenda Builder to choose CI-CD Keywords. You should be able to easily find out what all sessions(breakout, community theatre, General or Workshops) is scheduled to happen on all 3 days.
 
 
I personally find Session Tracks very useful. This time in Barcelona, I will try my best to attend most of these tracks listed below – 
 
– Using Docker for Developers
– Using Docker for IT Infrastructure & Ops
– Customer Stories
– Black Belt
– Docker Technology
– Ecosystem
– Community Theatre
 
 
 

#2. Don’t Miss out HTP – Dockercon 2018 Hallway Track Platform

Trust Me..Dockercon is full of life-time opportunities. If you’re looking for a place which offers you a great way to network and get to know your fellow Docker enthusiasts, the answer is Hallway Tracks.

Hallway Track is an easy way to connect and learn from each other through conversations about things you care about. Share your knowledge and book 1-on-1 group conversations with other participants on the Hallway Track Platform. 

Recently I submitted a track around self-initiated DockerLabs community program. You can join me directly via https://hallwaytrack.dockercon.com/topics/29045/

 

Did you know that you can even enroll yourself for Hallway Track right away before Dockercon? If interested, Head over to https://hallwaytrack.dockercon.com/

#3. Get Your Hands Dirty with HOL –  Dockercon 2018 Hands-on Labs (HOL)

With Dockercon conference pass, comes a Docker’s Hands-on Lab. These self paced tutorials allow you to learn at your pace anytime during the conference. Featuring a wide range of topics for developers and sys admins working with Windows and Linux environments. The Docker Staff will be available to answer questions and help you along. 

What I love about Docker HOL is you don’t need pre-registration, just stop by during the available hours on Monday through Wednesday. All you need is carry your laptop for lab sessions.

Further Information: https://europe-2018.dockercon.com/hands-on-labs/

 

#4. Deepen Your Container Knowledge with DW – “Dockercon 2018 Workshops”

Pre-conference Docker workshops is an amazing opportunity for you to become better acquainted with Docker and take a deep dive into the Docker platform features, services and uses before the start of the conference. These two hour workshops will provide technical deep dives, practical guidance and hands on tutorials. Reserving a space require just a simple step – RSVP with your Agenda Builder. Please note that this is included under Full Conference Pass.

Below are the list of workshops you might be interested to attend on Monday, Tuesday & Wednesday(Dec 3 – Dec 5 2018):

 

252727 – Workshop: Migrating .NET Applications to Docker Containers

#5. Meet Your Favourite Captains & Community Leaders via  Dockercon! Pals

DockerPals is an excellent opportunity to meet Docker Captains and Community Leaders who are open to engaging with container enthusiasts of all skill levels, specialities and backgrounds. By participating in Docker Pals you will be introduced to other conference attendees and connected with a DockerCon veteran, giving you a built-in network before you arrive in Barcelona.

If you’re new to Dockercon, you can sign up as a Docker Pal. Docker Pals are matched with 4-5 other conference attendees and one Guide who knows their way around DockerCon. Pals might be newer to DockerCon, or solo attendees who want a group of new friends. Guides help Pals figure out which sessions and activities to attend and are a familiar face at the after-conference events. Both Guides and Pals benefit from making new connections in the Docker Community. You can sign up for Docker Guide under this link.

 

#6 Don’t Miss out Black Belt Sessions

Are you code and demo-heavy contributor? If yes, then you gonna love these sessions.

Attendees of this track will learn from technical deep dives that haven’t been presented anywhere else by members of the Docker team and from the Docker community. These sessions are code and demo-heavy and light on the slides. One way to achieve a deep understanding of complex distributed systems is to isolate the various components of that system, as well as those that interact with it, and examine all of them relentlessly. This is what is discussed under the Black Belt track! It features deeply technical talks covering not only container technology but also related projects.

 

Looking out for Tips for attending Conference???

Earlier this year, I presented a talk around “5 Tips for Making Most out of International Conference” which you might find useful. Do let me know your feedback, if any.

If you still have queries around Dockercon, I would suggest you to join us all at Docker Slack channel. Search for #dc_pals Slack channel to get connected to DockerPals program.

To join Docker Slack, you are requested to go through this link first. 

 

How to become a DevOps Engineer?

Estimated Reading Time: 2 minutes

 

Who is DevOps engineer?
       
 DevOps engineers are a group of influential individuals who encapsulates depth of knowledge and years of hands-on experience around a wide variety of open source technologies and tools. They come with core attributes which involve an ability to code and script, data management skills as well as a strong focus on business outcomes. They are rightly called “Special Forces” who hold core attributes around collaboration, open communication and reaching across functional borders.

 DevOps engineer always shows interest and comfort working with frequent, incremental code testing and deployment. With a strong grasp of automation tools, these individuals are expected to move the business quicker and forward, at the same time giving a stronger technology advantage. In nutshell, a DevOps engineer must have a solid interest in scripting and coding,  skill in taking care of deployment automation, framework computerization and capacity to deal with the version control system.

 

Qualities of a DevOps Engineer

  Collated below are the characteristics/attributes of the DevOps Engineer.

  • Experience in a wide range of open source tools and techniques
  • A Broad knowledge on Sysadmin and Ops roles
  • Expertise in software coding, testing, and deployment
  • Experiences on DevOps Automation tools like Ansible, Puppet, and Chef
  • Experience in Continuous Integration, Delivery & Deployment
  • Industry-wide experience in implementation of  DevOps solutions for team collaborations
  • A firm knowledge of the various computer programming languages
  • Good awareness in Agile Methodology of Project Management
  • A Forward-thinker with an ability to connect the technical and business goals     
  • Demand for people with DevOps skills is growing rapidly because businesses get great results from DevOps. Organizations using DevOps practices are overwhelmingly high-functioning: They deploy code up to 30 times more frequently than their competitors, and 50 percent fewer of their deployments fail.

What exactly DevOps Engineer do?

DevOps is not a way to get developers doing operational tasks so that you can get rid of the operations team and vice versa.  Rather it is a way of working that encourages the Development and Operations teams to work together in a highly collaborative way towards the same goal. In nutshell, DevOps integrates developers and operations team to improve collaboration and productivity.

Duties of Developing and Operations team

The main goal of DevOps is not only to increase the product’s quality to a greater extent but also to increase the collaboration of Dev and Ops team as well so that the workflow within the organization becomes smoother & efficient at the same time.

Kubernetes Hands-on Lab #4 – Deploy Prometheus Stack using Helm on Play with Kubernetes Platform

Estimated Reading Time: 8 minutes

 

Let’s talk about Kubernetes Deployment Challenges…

As monolithic systems become too large to deal with, many enterprises are drawn to breaking them down into the microservices architecture.Whenever we move from monolithic to microservice architecture, application consists of multiple components in terms of services talking to each other. Each components has its own resources and can be scaled individually. If we talk about Kubernetes, it can become very complex with all the objects you need to handle ― such as ConfigMaps, services, pods, Persistent Volumes ― in addition to the number of releases you need to manage. The below list of challenges might occur :

 

 
 
1. Manage, Edit and Update multiple k8s configuration
2. Deploy Multiple K8s configuration as a SINGLE application
3. Share and reuse K8s configurations and applications
4. Parameterize and support multiple environments
5. Manage application releases: rollout, rollback, diff, history
6. Define deployment lifecycle(control operations to be run in different phases
7. Validate release state after deployment
 
These can be managed with Kubernetes Helm, which offers a simple way to package everything into one simple application and advertises what you can configure.
 

Helm is a Deployment Management(and NOT JUST PACKAGE MANAGER) for Kubernetes. It does a heavy lifting of repeatable deployment, management of dependencies(reuse and share), management of multiple configurations, update, rollback and test application deployments(Releases).

Under this blog post, we will test drive Helm on top of Play with Kubernetes Platform. Let’s get started.

Open https://labs.play-with-k8s.com/ to access Kubernetes Playground.

Click on the Login button to authenticate with Docker Hub or GitHub ID.

 

Once you start the session, you will have your own lab environment.

Adding First Kubernetes Node

Click on “Add New Instance” on the left to build your first Kubernetes Cluster node. It automatically names it as “node1”. Each instance has Docker Community Edition (CE) and Kubeadm already pre-installed. This node will be treated as the master node for our cluster.

Bootstrapping the Master Node

 

You can bootstrap the Kubernetes cluster by initializing the master (node1) node with the below script. Copy this script content into bootstrap.sh file and make it executable using “chmod +x bootstrap.sh” command.

When you execute this script, as part of initialization, the kubeadm write several configuration files needed, setup RBAC and deployed Kubernetes control plane components (like kube-apiserver, kube-dns, kube-proxy, etcd, etc.). Control plane components are deployed as Docker containers.

Copy the above kubeadm join token command and save it for the next step. This command will be used to join other nodes to your cluster.

Adding Worker Nodes

Click on “Add New Node” to add a new worker node.

Checking the Cluster Status

[node1 ~]$ kubectl get nodes
NAME      STATUS     ROLES     AGE       VERSION
node1     Ready      master    18m       v1.11.3

node3     Ready      <none>    39s       v1.11.3
node4     NotReady   <none>    22s       v1.11.3
node5     NotReady   <none>    4s        v1.11.3
[node1 ~]$
