PGP can refer to two things:
The Pretty Good Privacy software originally written by Phil Zimmermann, and now owned by Symantec. The formats for keys, encrypted messages and message signatures defined by that software. These have now been formalised as the OpenPGP standard. The GPG software is an independent implementation of the OpenPGP standards, so you can use it to exchange encrypted messages with people using other OpenPGP implementations (e.g. Symantec's PGP).
Picking the right architecture = Picking the right battles + Managing trade-offs
Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...
// see: https://github.com/chadoe/docker-cleanup-volumes
$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker volume ls -qf dangling=true | xargs -r docker volume rm
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.
