Secrets Example

Overview

In this example, you will create a pair of x.509 certificates for the public and private keys to encrypt and decrypt messages.

You will then create a compose file for a service that you will configure with the private key. You will encrypt messages using the public key, then send the encrypted messages to the service.

This is a simplified makefile for making it easy to to rebuild whatever needs rebuilding when touching any of the protocol buffer files or other source files for either the server or the cli.

For convenience, I use an alias:

$ alias m="make -f amp.makefile"

Then I just invoke m to make all, and then m deploy to update the stack, then restart logs in another terminal (docker service logs -f amplifier_amplifier).

Overview

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.

I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/ in my Dockerfiles, and also work from isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/.

At the end of the day, vendoring (and committing vendor/) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:

Keybase proof

I hereby claim:

I am subfuzion on github.
I am subfuzion (https://keybase.io/subfuzion) on keybase.
I have a public key ASDaezjPtNiBGf-CDL4gmWviZ8RURHuHmO_ALSNAKopREgo

To claim this, I am signing this object:

Here's an example of how to debug Mocha v4 if it hangs.

Ensure you're using a Node.js 8 or newer (or any version with async_hooks support).

If you run your test, you'll notice it hangs:

$ mocha test.js

For Voting App

Need MySQL queries for the following:

Statement: create voter. Register a unique username of reasonable lengths (3-64 characters, such as "tonypujals" and password to be able to vote. Password field will store bcrypt-encrypted strings, specifically:

CHAR(60)
CHARACTER SET latin1
COLLATE latin1_bin

Overview

The Istio docs provide comprehensive instructions for setting up Istio for a variety of environments. You will want to refer to them to understand the variety of configuration options and for more in depth explanations for the related topics. The following are concise notes based on my own experience running Istio using Docker for Mac with Kubernetes enabled, and basically meant to be a guide for demo purposes. Others may find this streamlined format useful as well.

Warning: the official docs for 0.8.0 are not entirely up-to-date. In particular, there are a number of errors in the Telemetry section. The steps in this guide have been verified to work.

To keep this concise, the setup is based on installing Istio

without using Helm
without mutual TLS between sidecars
with automatic sidecar injection

Sample template (greeting.tpl) for testing with subfuzion/envtpl. Note that the template pipes to the title function, which will convert the value of $USER in your shell to initial uppercase (ex: tony => Tony).

Make sure you click the Raw button for greeting.tpl to get the correct link.
