I was not able to find a Dockerfile for running Talend Remote Engine in a container. So I tried to build a new one. It is a working in progress: do you have any suggestions? TODO / Next steps: registering the engine using Talend API running the engine with a unix user “talend” FROM centos:7 # centos is the recommended linux distribution MAINTAINER Matteo Redaelli <matteo.redaelli@gmail.com> # Build and run this image with: # - docker build -t talend/remote_engine:2....

Deploying you applications in containers, you are sure that they are easily portable and scalable… Here a sample of deploying a .war application using a Docker container Create a Dockerfile like``` FROM tomcat:8-jre8 MAINTAINER “Matteo matteo.redaelli@gmail.com” ADD server.xml /usr/local/tomcat/conf/ ADD tomcat-users.xml /usr/local/tomcat/conf/ ADD ojdbc6.jar /usr/local/tomcat/lib/ ADD bips.war /usr/local/tomcat/webapps/ Build a docker image docker build . -t myapp Run one or more docker images of your appplication with docker run –restart=unless-stopped –name myapp1 -p 8080:8080 -d myapp docker run –restart=unless-stopped –name myapp2 -p 8081:8080 -d myapp It is better to redirect tomcat logs to stdout: in this way you can see them with docker logs myapp

I already spoke about docker containers (moving datacenters apps from virtual machines to containers) This is a quick tutorial (my github sample code) about a new way of deploying (micro) services and applications, ie using Docker containers: a sample python webservice and an simple web (html + angularJS code) page Creating docker containers means defining a file Dockerfile like``` FROM python:3.5 #FROM python:3-onbuild ENV DEBIAN_FRONTEND noninteractive ENV HTTP_PROXY=“http://myproxy.redaelli.org:80” ENV HTTPS_PROXY=“http://myproxy.redaelli.org:80” ENV http_proxy=“http://myproxy....

What is the best linux distribution for Raspberry PI2? I started with Raspian (Debian is my preferred Linux distribution for servers, desktops and laptops) but docker didn’t work. But with Archlinux it works fine. How to create a docker images with Archlinux & RPI2? See http://linucc.github.io/docker-arch-rpi2/ matteoredaelli/docker-karaf-rpi is the first docker image I have created. Below my docker info output: [root@raspi1 ~]# docker info Containers: 4 Images: 9 Storage Driver: aufs Root Dir: /var/lib/docker/aufs Backing Filesystem: extfs Dirs: 17 Execution Driver: native-0....

“Docker, a new container technology, is hotter than hot because it makes it possible to get far more apps running on the same old servers and it also makes it very easy to package and ship programs…” Read the full article at zdnet.com
