Setup HashiCorp Vault on docker

Vault secures, stores, and tightly controls access to tokens, passwords, certificates, API keys, and other secrets in modern computing. Vault is primarily used in production environments to manage secrets. Vault is a complex system that has many different pieces. There is a clear separation of components that are inside or outside of the security barrier. Only the storage backend and the HTTP API are outside, all other components are inside the barrier.

Figure 1: Architecture of Vault and Spring App (Click to enlarge)

The storage backend is untrusted and is used to durably store encrypted data. When the Vault server is started, it must be provided with a storage backend so that data is available across restarts. The HTTP API similarly must be started by the Vault server on start so that clients can interact with it.

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Description

UPDATED 9/2/2023 - here we are a few years later, adguuard has been stable as heck now i wanted to add IPv6 to this mix these were the steps

1. stop the stack
2. delete the 6 adguard config networks and the two deployed macvlans from within portainer
3. recreate using the instructions below adding the following for IPv6 (note the Ipv6 are the documented subnet examples - don't use them, use ones right for your network)

Development environment with Nix Flakes and Direnv

This document is targeted at those who seek to build reproducible dev environment across machines, OS, and time.

It maybe easier for remote teams to work together and not spending hours each person setting up asdf/pyenv/rbenv, LSP servers, linters, runtime/libs. Nix is probably the closest thing to Docker in terms of development environment.

Flake is used here because it provides hermetic build, with absolutely no reliance on system environment (be it Arch/Catalina/Mojave). Also it freezes dependencies in flake.lock so builds are reproducible.

This gist provides the setup to develop Java/Clojure/Python applications on Nix. But it can be easily adapted to ruby, nodejs, haskell.

### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. 
###.   Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of 
###.   things to watch out for:
###      - Check out the `nix-darwin` instructions, as they have changed.
###      - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.
