A multi-container Symfony2 setup with Docker

Transcript

Geoffrey Bachelet – @ubermuda A multi-container Symfony2 setup with Docker.

Container Engine? Based on the Linux kernel's LXC instructions Processes

and resources isolation "chroot" on steroids / super lightweight VMs

Host OS Hypervisor Guest OS Guest OS Guest OS Guest

OS App App App App Host OS Docker + LXC App App App App VMs vs Containers

Host OS Hypervisor Guest OS Guest OS Guest OS Guest

OS App App App App Host OS Docker + LXC App App App App VMs vs Containers

VMs vs Containers LXC / Jails / Zones / etc

Uses the host's kernel Boots in seconds 0 overhead (almost) Easy to pass around Hypervisor Boots a complete OS Boots in minutes Guest OS' overhead Several Go images
