• Use correct auth credentials when pulling a runtime image for an extended build

1.0 Changelog

• switched from using environment variables to labels:
  • STI_SCRIPTS_URL -> io.s2i.scripts-url
  • STI_LOCATION -> io.s2i.destination
• renamed location flag and label to destination
• fixed handling relative paths when specifying --scripts-url flag
• cleaned up internal API
• adding 'latest' tag for builder when no tag is specified
• fixed flag error handling
• added support for --environment-file/-E
• fixed getting output from containers

• Updated release builder image to cross compile properly.

Note: This release includes osx and windows binaries again.

• Added --dockercfg-path to allow users pulling Docker images from private repositories
• Use less layers when adding environment variables to the output Docker image
• Display output from stderr when running save-artifacts scripts
• Fix issue when having an archive with many files can reach the system limits (ulimit -n)
• Added human-friendly printer for the STI request object (--loglevel=>2)
• Prevent pulling the previous image during incremental build when --force-pull=false
• Switched to use dashed case for command line arguments (--forcePull is now --force-pull)

Note: We ran into some issues with the cross compiler so we were not able to produce the mac and windows binaries, but you should be able to build your own version in those environments.
