When it comes to databases and AWS VPC, best practice is to place your database in private subnet. By definition, private subnet in AWS is not reachable from the Internet because no Internet gateway is attached to private subnet. This is the way you protect your data. This kind of configuration is good for security but bad for data management.

How can you easily access and manage your secured data?

There are two basic ways to acees it.

1. Access postgres RDS from bastion host. There are following requirements for this.

# Get a local Shell of container
      docker run -i -t --entrypoint /bin/bash imageID
# Create image using this directory's Dockerfile
      docker build -t friendlyname .
# Run "friendlyname" mapping port 4000 to 80
      docker run -p 4000:80 friendlyname
# Same thing, but in detached mode
      docker run -d -p 4000:80 friendlyname
# See a list of all running containers
     docker ps

Introduction

This works to install Open GApps into the Android Emulator, working around the issue where the system partition is too small.

With it, I can get Google Play installing into the emulator. Tested on KitKat (API 19), Lollipop (API 21) and Oreo (API 27).

It's tested on MacOS.

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.
