General and Concepts

• Declarative Deployments & why it matters

Over the last 30 years, the Configuration Management community has learned that using a declarative approach to resource management is beneficial for both stability and change management. How does this apply to the new paradigm of Kubernetes deployments?

• YAML Engineering: why we need a new paradigm

YAML has become the de-facto standard to express resources in many fields linked to DevOps practices. What are YAML's strengths and weaknesses, and what are the other options going forward?

# Generate and use an oauth2 bearer token for the Twitter API in Ruby
#
# For Application-Only authentication to the twitter API, a 'bearer token'
# is required to authenticate agains their endpoints for rate limiting
# purposes.
# 
# This script generates a bearer token by posting to twitter and then it
# uses that token to poll their API.
#
# Note, the base 64 encoded consumer credentials for the bearer token needs

Docker Macvlan and Ipvlan Experimental Driver Examples

• The build will be vendored into github.com/docker/docker in the next few days. In the meantime here is the binary that will be getting vendored. docker-1.11.0-dev.zip
• Ipvlan L2 mode network with multiple subnets without a parent specified
• For a long test that will create 54 networks and 120+ containers, then delete them all and recreate them again try ipvlan-macvlan-it.sh Instructions here Docker Macvlan and Ipvlan Manual IT Test
• FYI Note: When the parent is empty or the --internal flag is used, a linux type dummy interface is dynamically created by Libnetwork to act as the parent. This network is completely isolated and is the equivalent to a --internal flag. This is a good mode for demoing.
• The first test requires an interface

$ pfctl -e enable                                 # packet-filtering
$ pfctl -q                                        # run quiet
$ pfctl -v -v                                     # run even more verbose
#### Loading PF Rules ####
$ pfctl -f /etc/pf.conf                           # load /etc/pf.conf
$ pfctl -n -f /etc/pf.conf                        # parse /etc/pf.conf, but dont load it
$ pfctl -R -f /etc/pf.conf                        # load only the FILTER rules
$ pfctl -N -f /etc/pf.conf                        # load only the NAT rules
