Flynn Progress: Week Ending Nov. 17, 2014

We smoothed out many rough edges in Flynn last week by removing some upstream dependencies. You’ll see improvements to our security and stability, along with better support for GitHub releases.

§ Changes

§ Enhancements

  • We updated to Go 1.4rc1 to improve reliability and security. This may also improve performance as development continues.
  • The router’s go-vhost package dependency was replaced with the new crypto/tls functionality in Go 1.4.
  • All Go subrepo paths have been updated. (#416)
  • Vagrant VMs now use IPs from RFC 5737 for host communication to work around DNS rebinding protection and avoid collisions. (#438)
  • We added a version command to flynn-host that will show the release version or git revision that it was built from. (#308)
  • We added a Makefile, so the make command should be used instead of calling tup directly. The make clean target replaces the clean shell alias.
  • Releases are now tagged on GitHub.
  • The flynn-release download command was moved to the flynn-host binary, and the flynn-release binary was removed from binary packages. (#446)
  • Flynn CI now tests all supported buildpacks. (#417)
  • Bootstrap now supports waiting for TCP services.
  • The flynn-bootstrap command was renamed to flynn-host bootstrap and the flynn-bootstrap binary was removed. (#449)

§ Bugfixes

  • Releases invalidate the correct CloudFront distribution. (#451)
  • We deleted our unmaintained Docker backend for the host daemon, closing out four Flynn issues. Support for Docker images remains a key feature of Flynn. (#430)

§ What’s Next

We expect to have nightly builds available shortly. We are focused on improving our test suite, documentation, and stability.
