Ask HN: Best container runtime for process isolation / security?
I'm currently considering a project where containers could be used to quickly spin up resources. Trick is, one user would "own" one container, meaning that isolation between containers and isolation between the host/container is important.
Most runtimes I've looked at, don't really offer anything in terms of security isolation, and also don't make a lot of guarantees. Seems I'll end up using VMs so I can get proper isolation.
But maybe I've missed something, and you people here know any good solution for this.
Point is to have fast startup time of the container/VM and also good isolation between the containers/VMs themselves, and between the container/host.
This is all supposed to run on self-hosted infrastructure and without Kubernetes et all, so Lambda and all "container-as-a-service" things are N/A
- gtirloni 6y agoLooks like you want this: https://firecracker-microvm.github.io/ https://firecracker-microvm.github.io/
- capableweb 6y agoThanks! That looks interesting and I had missed it.
- cpach 6y agoI highly recommend reading through Fly’s blog posts. They let customers build Docker images, which are then transformed to Firecracker VMs. Very cool! https://fly.io/blog/docker-without-docker/ https://fly.io/blog/docker-without-docker/
- helixc 6y agoExactly what I'm looking for. Waiting for more insights.
- kasey_junk 6y agoI’m not making a claim about its quality but gvisor is another isolation focused runtime https://github.com/google/gvisor https://github.com/google/gvisor
- yamellasmallela 6y agofirecracker is probably what you need that literally runs lambda gvisor is also good for pure container runtimes
