Jenkins 1.625.3
Amazon EC2 plugin 1.31
Master and slaves running Ubuntu 14.04
I noticed my Unix slaves on EC2 do not have a ~/.hudson-run-init file, despite running the init script (and following setup steps) successfully. As a result, when they're brought back up from a stopped state, they run the init script again, wasting ~20 minutes.
Some relevant AMI configuration:
- Remote FS root: /home/ubuntu
- Remote user: ubuntu
- AMI Type: unix
- Root command prefix: sudo
- Init script is essentially: sudo $HOME/init_script.sh
On a successfully connected slave, I expect to see /home/ubuntu/.hudson-run-init, but there's no such file. I took a quick look at EC2UnixLauncher.java, and everything looks reasonable. My only question is why touch ~/.hudson-run-init would need to be run as root. But both touch ~/.hudson-run-init and sudo touch ~/.hudson-run-init produce the expected file when run manually as the ubuntu user. So I'm a bit stumped.
I'm testing out touching the file myself in the init script as a workaround.
