Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

1️⃣ Docker daemon 配置代理（推荐）

Set up VGW on AWS with OpenSwan

You will need 2 VPCs. The Internet VPC will have the Internet Gateway and the OpenSwan EC2 instance. The Project VPC will have your application or Kubernetes cluster.

Internet VPC

VPC CIDR: 10.230.30.0/24
Private Subnet: 10.230.30.128/25 - Route Table with 0.0.0.0/0 to NAT
Public Subnet: 10.230.30.0/25 - Route Table with 0.0.0.0/0 to IGW, 10.224.36.0/23 to OpenSwan Instance
NAT Gateway in the public subnet with an IP of 52.15.61.171

Shadowsocks Proxy

Server-side setup

apt-get install python-pip
pip install shadowsocks

sudo ssserver -p 443 -k password -m aes-256-cfb --user nobody -d start

	# Amazon Neptune version 4 signing example (version v2)

	# The following script requires python 3.6+
	# (sudo yum install python36 python36-virtualenv python36-pip)
	# => the reason is that we're using urllib.parse() to manually encode URL
	# parameters: the problem here is that SIGV4 encoding requires whitespaces
	# to be encoded as %20 rather than not or using '+', as done by previous/
	# default versions of the library.

	#!/bin/bash
	set -o errexit

	source ./library
	# Entry point of the script.
	# If makes sure that the user supplied the right
	# amount of arguments (image_name)
	# and then performs the main workflow:
	# 1. retrieve the image digest
	# 2. retrieve the layer info of image

	#!/usr/bin/env ts-node

	// This script uploads your assets to the CDK staging bucket in S3 (just as cdk deploy would)
	// and writes out two files:
	// - parameters.ini to use in CLI deployments (see instructions below)
	// - parameters.json to use in AWS CodePipeline for CloudFormation deployments
	//
	// Installation instructions:
	// - Save this script cdk-package.ts to the root of your CDK repo (i.e. next to cdk.json) and make it executable
	// - Install script dependencies: npm install jsonpath aws-sdk adm-zip @types/jsonpath @types/adm-zip

	import ec2 = require('@aws-cdk/aws-ec2');
	import cdk = require('@aws-cdk/core');

	import { Fn, Tag, Resource } from '@aws-cdk/core';
