Docker is Everywhere

Here is a blog post I posted on my blog at Cybercom.

If I should mention one topic that has been more or less on everybody’s lips at every conference I have attended in 2014, it would be Docker. I do not think I have ever seen a technology that has been embraced by so many so fast before.

So what is Docker then?

In short, it is a platform for building, shipping and running applications using containerization.

Read more about it at https://www.docker.com/whatisdocker/

Here are a couple of examples:

Get ubuntu images from Docker Hub:

$ docker pull ubuntu

Starting a container running Ubuntu 14.04 is as easy as this:

$ docker run -it ubuntu/14.04 /bin/bash

Deploying an application in a container running Wildfly on Ubuntu can be done by creating a Dockerfile similar to this (ivargrimstad/ubuntu-wildfly is a Docker image I have uploaded to my repository at Docker Hub (https://hub.docker.com/u/ivargrimstad/):

FROM ivargrimstad/ubuntu-wildfly
ADD ./app.war /opt/jboss/wildfly/standalone/deployments/app.war

Build the image:

$ docker build --rm -t myapp .

And run the application on port 80:

$ docker run -it -p 80:8080 myapp

These were just a couple of easy examples to get you startet. Try the Docker tutorial at https://www.docker.com/tryit/ to try it out without installing anything locally.

 

2014 Conferences

I know it is a bit early to sum up the year in November, but since I have not planned any more conference talks this year I think I will do it anyway. As the picture shows I have been pretty active this year.

 

2014-11-08 12.15.31

I have been presenting at conferences in Norway (Software 2014), Sweden (Javaforum, Øredev), Germany (Javaland), Poland (JDD), Ukraine (JEEConf, JavaDayKiev) and Morocco (JMaghreb). In addition to my speaker appearances, I was also able to attend JavaOne in San Francisco where I got to meet a lot of people in the JCP and ended up being selected to the Expert Group for JSR 371 – MVC 1.0.

I hope to continue speaking at a lot of conferences next year as well. Talks have already been accepted by jDays and Javaland, so it looks promising.

Joining the Experts

I have been a member of the Java Community Process (JCP) for nearly ten years. My contribution so far has been to vote in elections and respond to surveys.

But recently this changed as I was selected to be a part of the Expert Group for JSR 371: Model-View-Controller (MVC 1.0) Specification. This JSR is targeted to be a part of Java EE 8.

I am looking very much forward to participating in this JSR and will post updates here now and then.

Building up to JavaOne

I am sitting at a Starbuck’s with a dark roast in my hand looking over some photos from Yesterday’s stroll in San Francisco. Some of them are pretty cool, so I’ll share them here…

What do you do with your boat after having won America’s Cup? Well, if your name is Larry you will probably use it as roof over a street you have closed for a week while hosting a party for 50-60.000 of your closest friends…

A Little Status Update

My schedule for the upcoming months are beginning to fill up as a result of submitting talks to a lot of CFPs during summer. The scheduled talks so far are:

There are still some room, so if you are organizing a conference and need talks to fill up, feel free to contact me. My profile on Lanyrd is kept updated at all time.

But first of all I am going to JavaOne! This year as an attendee, so it is all about networking, community building and interesting technical sessions and keynotes.

Upcoming Talks

I think time is due for a small update post. Right now I am preparing code samples and slides for the upcoming talks this winter:

  • Javaforum, Gothenburg – Spring 4, Java EE 7 or Both?
  • Software 2014, Oslo – Organizing for Continuous Delivery
  • JavaLand 2014, Brühl – Spring 4, Java EE 7 or Both? and Implementing Batch Processing in Java EE 7

My profile at Lanyrd is also kept up-to-date.

Views From a Speaker at JDD 2013

JDD 2013

I have just come home after spending three amazing days in Krakow as one of the speakers at the Java Developer Days Conference there. The organizers of this conference takes well care of their speakers and you feel welcome all the time. And I am sure the attendees feel the same.

Apart from my talk, my greatest achievement at the conference was to win a a signed copy of Practical API Design by implementing a simple application using bck2brwser. My contribution: Duke2Brwser. Hope this may inspire you to try it out. Just activate the HTML/Java Project Support plugin in NetBeans and go ahead!
