---------------------------------
Summary: Rya vagrant script difficult to see failures
Key: RYA-54
URL: https://issues.apache.org/jira/browse/RYA-54
Project: Rya
Issue Type: Bug
Components: examples
Environment: Rya in a VM
Reporter: David W. Lotts
Assignee: David W. Lotts
Rya example virtual machine is a wonderful way for new users to get up and
running fast and have a positive first experience with Rya.
Several folks have attempted to create the Rya example virtual machine and
produce an unusable Rya instance on the first try. They have no clue what went
wrong since they saw no errors and it appeared to complete successfully. Only
when they attempt to use the web interface do they see errors.
The relevent files are here:
https://github.com/apache/incubator-rya/tree/develop/extras/vagrantExample/src/main/vagrant
There are several reasons for this having to do with the {{Vagrant up}} command
that runs the Vagrantfile, a combination of vagrant specific syntax, and Bash
shell script:
- The curl download utility produces a nice progress output meant for a
terminal, but Vagrant adds newlines so that it scrolls and fills up the
terminal buffer obscuring any errors messages that occur.
- Most failures are tolerated and allow the process to continue even when the
failure creates an unusable VM.
- Running the command {{vagrant provision}} is not idempotent. When run more
than once, it should reset the configuration as it was installed, making it a
handy repair tool, however it generates false errors and fails. Also, it
re-downloads very large files that are already present, making it no better
than starting over.
