Overview

Conteinerizing apps and systems.

Technologies

• Docker-1.12+

• others

  • Rancher
  • Mesos
  • DC/OS

Contributors

Compatibility

Built on CEntOS-7 as base operating system.

Moreover, we also have some debian8, python-2.7 and Ubuntu-16 Dockerfile to build images, but these ones aren't supported - this is PoC only.

Tags

• standard and supported:
  • centos7 (latest): built based on centos:7 image

PoC only

Proof of Concept for image sizes:

• debian8: built based on debian:jessie image
• python27: built based on python:2.7 image
• ubuntu16: built based on ubuntu:xenial image

Requirements

• Docker-1.12+ https://docker.com

Optionals

• VirtualBox-5.0+ http://www.virtualbox.org/
• Vagrant-1.7+ http://vagrantup.com/
  • Vagrant plugins

    • vagrant-persistent-storage: creates a persistent storage and attaches it to guest machine

    • vagrant-proxyconf (Proxy Configuration Plugin for Vagrant)

    • vagrant-cachier: share a common package cache among similar VM instances

    • vagrant-hosts (vagrant-hosts - Manage vagrant guest local DNS resolution)

    • vagrant-hostsupdater (Vagrant::Hostsupdater - adds an entry to your /etc/hosts file on the host system)

      • optional install and use it only if you're behind a proxy
  • Box adrianovieira/centos7-docker1.12-GA or adrianovieira/boxes/centos7-kernel4.4-vbox5.0-docker1.12GA (published on https://atlas.hashicorp.com/adrianovieira/boxes)

Setup and Tasting

Docker

First of all we need a host with Docker-1.12+ pre-installed and running. May be you could use one of my "Docker boxes" https://atlas.hashicorp.com/adrianovieira/boxes with built-in docker-1.12.

Docker Proxy

If you are behind a proxy and is having problems pulling docker imagens... setup Systemd Docker own Service, as below (well done on CEntOS-7):

# setup docker service proxy (as root user)
mkdir -p /etc/systemd/system/docker.service.d
echo "[Service]" > /etc/systemd/system/docker.service.d/proxy.conf
echo "Environment='HTTPS_PROXY=$HTTP_PROXY' 'HTTP_PROXY=$HTTP_PROXY'" >> /etc/systemd/system/docker.service.d/proxy.conf
systemctl daemon-reload && systemctl restart docker

keep CALMS and having fun
