What Hacker News says?

  1. > host their own stuff and just make them searchable/discoverable You aware that hosting probably represent 1% of Docker spending at the moment ? You aware that Docker has 100+ employees based in SF where the average salary is 120K$/Year ? And here I'm being gentle not to include the management[0] which in general has salary closer to 300K than 120K [0] https://www.docker.com/company

  9. This is exactly how Docker works too - they recently rate limited anonymous accounts, and by signing up for the free plan you agree to very similar terms and conditions in return for a higher pull rate limit.

  15. "Docker Desktop" uses a VM for container execution on all supported OSes - Windows, macOS and Linux - default installs are not running "docker" natively at your local CLI if you are using "Docker Desktop" to run docker, even on Linux. > https://www.docker.com/blog/the-magic-behind-the-scenes-of-d... > https://docs.docker.com/desktop/install/linux-install/ > https://docs.docker.com/desktop/faqs/linuxfaqs/#what-is-the…

  17. I'm pretty sure the main reason there's a push to move from Docker Desktop now is because earlier this year they started charging larger businesses/teams to use it. So if you're just using it for yourself you probably don't need to bother https://www.docker.com/blog/updating-product-subscriptions/

  19. Docker Desktop for Mac released an experimental file sharing implementation back in March[0]. It made working with Docker bearable. Does anyone know how well Podman performs on Mac? Especially file sharing. Edit: A quick Google led me back to this HackerNews comment[1]. Looks like Docker for Mac is faster. [0] https://www.docker.com/blog/speed-boost-achievement-unlocked...

  25. They tried that ("Docker Enterprise Edition") years ago, with some minor differentiation on features only available in EE... but for $62-300/node/month. This is now the part Mirantis owns, current Docker is the developer-focused side. https://www.docker.com/blog/docker-enterprise-edition/ https://web.archive.org/web/20171118161452/https://www.docke...
