Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

Docker Registry API V1 walkthrough

Matthew Riley ([email protected])

This document summarizes the interactions between the Docker client and the Docker Hub during push and pull commands through version 1 of the registry API. It was compiled to aid in writing a compatible registry server implementation after the existing API documentation proved occasionally incomplete or inaccurate.

Behavior and code links were as of Docker v1.2.0.

docker {push|pull} H:P/R[:T]
Host, Port, Repository ([namespace/]image), Tag

git clone https://gist.github.com/dd6f95398c1bdc9f1038.git vault
cd vault
docker-compose up -d
export VAULT_ADDR=http://192.168.99.100:8200

Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.

Getting Started
