RHEV: How to run rhevm-shell in cron
Issue
Trying to automate a rhevm-shell script in cron is failing with:
OSError: [Errno 6] No such device or address: '/dev/tty'
This solution describes a workaround to the problem, which was reported in "Invoking rhevm-shell commands from non-interactive shell gives error as OSError: [Errno 6] No such device or address: '/dev/tty'". As stated in that solution:
- rhevm-shell presently doesn't have cli invocation capabilities, so without an interactive shell it is not possible to execute the rhevm-shell.
- An RFE is filed to get cli invocation capabilities for rhevm, see Bug#823515
However, if running rhevm-shell from crontab is a requirement now, the following steps will allow rhevm-shell to be successfully run from cron.
