10. Brief history of container runtimes “Containers are processes, born from tarballs, anchored to namespaces, controlled by cgroups” @alicegoldfuss
11. Brief history of container runtimes • Chroot - 1982 • FreeBSD Jails - 2000 • Solaris Zones - 2004 • Process Containers (cgroups) - 2006 • LXC - 2008 • Systemd-nspawn - 2010-2013 • Docker - 2013
12. Brief history of container runtimes • Docker - 2013 • ? • ? • ? • ? • ? • ?
13. Brief history of container runtimes • Docker - 2013 • LMCTFY (Let Me Contain That For You) - 2013 • LXD - 2014 • rkt - 2015 • CRI-O - 2016 • Kata Containers - 2017 • PouchContainer - 2018
14. Brief history of Docker • First public version built on LXC [2013] • moved to libcontainer [2014]
15. Brief history of Docker • moved to runC (OCI compliant) [2015] • Containerd [2016] • Moby [2017]
19. Docker 1.13.1 -> 17.03 Docker Engine -> Docker CE / EE
23. Docker 1.10 Docker 18.09 beta
24. BuildKit New open source builder toolkit Fast, safe, extensible
25. BuildKit Performance example Based on github.com/moby/moby Dockerfile, master branch. Smaller is better. Time for full build from empty state 2.0x faster Measured on DO 4vcpu droplet
26. BuildKit Performance example Based on github.com/moby/moby Dockerfile, master branch. Smaller is better. Fresh build with --cache-from from remote source 9.1x faster Measured on DO 4vcpu droplet
27. 33.1x 10.6x 8.1x Dockerfile syntax directive Example: RUN --mount moby/buildkit Dockerfile: time to binary rebuild after code change slower slower slower Measured on DO 4vcpu droplet
