Transcript

1. Deploying Python Christine Spang @spang spang@nylas.com …without Docker!
2. • Stable, reliable, low maintenance • Bundles all Python dependencies • Fast and painless to deploy • Easy to roll back to any version • …across hundreds of servers! Our deployment system
3. Debian Packages (the original containers)
4. Deployment flow S3 Python & requirements.txt Git Repo Debian Package Jenkins CI $ ./deploy-it Production Fleet
5. • built by Spotify in ’13 (thanks!!!) • Embeds a virtualenv in a Debian package (.deb) • https://github.com/spotify/dh-virtualenv • https://github.com/nylas/make-deb dh-virtualenv
6. • we use git SHAs for version #s • no debian version #s to bump to release! • we don’t maintain an internal apt server • deploy script installs using dpkg Versioning
7. Why not Docker?
8. • Same benefit using simpler, stabler tools • We only run a handful of services (not hundreds) • Don’t have to change any development workflow • debs+VMs work well for our level of complexity Why .deb instead of Docker?
9. Python 2.7 + .deb == ULTIMATE STABILITY!
