If I were to start a company tomorrow, what should I use instead of Docker? Heroku and dev laptops' filesystems?
Heroku's always nice and simple for getting stuff out there.
Vagrant + a provisioner of your choice is still good alternative and works solidly for local development if you want to keep developing away from the local filesystem.
There are quite a few options that don't involve docker at all, it just takes a little research to remind yourself that there's a world outside of the one presented by docker :/
Edit: s/pacman/podman/
Like, each type of application I have to run in my fleet needs the right environment, with proper settings, packages, etc. And when a developer at the company needs to work on that service locally, they need a prod-like env spun up quickly and simply that they can easily work in.
There's many ways to do this, like "one prod box and ssh" but they all have tradeoffs...
Is there a file format like "docker-compose.yml", where I can describe a handful of Jails that can talk to each other in their own virtual network, and that sets up a handful of services exactly as I describe?
Ideally, a Windows user, a Linux user and a Mac OS user check out this file, run a command ("voodoo up") in the directory of that file, and have a VM with the FreeBSD jails setup running exactly as described in the file.
I'd pay money for that.
- FreeBSD style jails already offer docker config, but here is an article showing a few basic things going on, notably the Network Access section has a FIXME by it: https://bsdwatch.net/articles/jails-as-virtual-servers
- For network isolation it looks like this package could help: https://klarasystems.com/articles/virtualize-your-network-on...
- For reproducibility you can use the FreeBSD package builder: https://docs.freebsd.org/en/books/handbook/ports/#ports-poud...
- FreeBSD has a Linux compatibility layer. FreeBSD running Docker: https://www.gamsjager.nl/2019/01/11/How-to-run-Docker-on-Fre...
- This thread is interesting: https://forums.freebsd.org/threads/docker-is-dead.69955/page...
I am going to explore this more in the coming weeks as I play around with FreeBSD.
