Artifacts

This is also first time we are publishing many binary artifacts along these release notes on GitHub to download from. These binaries match exact files used by new capstan to build OSv images and go into $HOME/.capstan directory. We hope these will make much easier for newcomers to OSv to try their apps. The published artifacts include:

  • osv-loader.qemu - OSv kernel
  • OSv modules
    • osv.bootstrap.* - default bootstrap
    • osv.cli.* - command line app
    • osv.httpserver-api.* - REST API (backed)
    • osv.httpserver-html5-cli.* - HTML5 command line app
    • osv.httpserver-html5-gui.* - HTML5 monitoring GUI
  • runtimes
    • osv.run-java.* - provides 'java' executable functionality in OSv to bootstrap Java apps
    • osv.run-go.* - tiny app to bootstrap Golang apps
    • osv.openjdk10-java-base.* - Java 10 minimal JRE repackaged to run Java apps on OSv
    • osv.node-js.* - Node 8.11.2 built as PIE shared library to run on OSv
  • example apps
    • iperf
    • lighttpd
    • memcached
    • mysql
    • netperf
    • nginx
    • redis

Going forward we will be publishing kernel and possibly modules binaries if they change.
