Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.

This is a copy/paste from an internal wiki on how we should use docker

This guide is to serve as an outline of internal best practices to using Docker. The idea is to give enough information to allow engineers to create containers for new stack components while minimizing the cleanup required to make them production ready.

Concepts

Before we get to the practices, it's important to understand WHY we are doing this. The key concepts we're concerned about with broad Docker usage are provenance, determinism, repeatability and auditability.

Provenance

Provenance refers to knowing WHERE something comes from. Generally with the end use of software, this is easy:

• Maven artifacts are pulled from central

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

# Add the following to your shell init to set up gpg-agent automatically for every shell
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gnupg/.gpg-agent-info

These instructions are for implementing HTTPS on a NFSN-hosted static site using a certificate from Let's Encrypt. The certificate is generated manually on a separate computer.

Start off by installing the letsencrypt client. This requires sudo privileges and will install a bunch of packages:

% curl -O https://dl.eff.org/certbot-auto
% chmod +x ./certbot-auto
% ./certbot-auto

Generate the certificate. This will require you to publish some challenge responses on NFSN. I find it easiest to use tmux with letsencrypt running in one window and an SSH session to NFSN in another:
