Defining env var from job

[waghanza]

Hi,

I'm working on https://github.com/tbrand/which_is_the_fastest and I have not expected result when running neph -> I'm on 0.1.21.

There is my config file

main:
  command:
    echo "The result is $CID"
  depends_on:
    -
      job: rails
      env: CID

rails:
  command: |
    sudo docker build -t rails .
    sudo docker run -td rails
  dir: ruby/rails

The expected result is tho show a container (docker) ID when running neph

Regards,

PS : I take inspiration from https://github.com/tbrand/neph/wiki/Set-a-job-result-to-env-vars

What is the current result?

[waghanza]

Nothing, the output is

Neph is running (0.1.21) ||||||||||||||||||||||||||||||||||||||||||||||||||100%
main [2/2] done.   2.39ms
 - rails [1/1] done.   1.44s

Finished in 1.5s

Neph don't redirects the output of jobs to the terminal, because it can run multiple jobs in parallel, and if each job prints to the terminal, it could mess up the output. It stores the stdout of the job in .neph/<job_name>/log/log.out, and the stderr in the same directory with the log.err name.

:+1: However, I have

The id 415fe87db28a8066f4cd47e6883e865a16262da7b3bacb377bc453c88ab6fe2b is what I expect (only this), but I can find in .neph/rails/log/log.out the output of subcommands :stuck_out_tongue:

[notramo]

If you run the commands of the rails job in the terminal (both commands), is the ID the only output?

[waghanza]

you're right :stuck_out_tongue: it is the output of both command ;-)

[waghanza]

so, this configuration is OK

main:
  depends_on:
    - rails

rails:
  command: |
    sudo docker build -t rails . &>/dev/null
    sudo docker run -td rails
  dir: ruby/rails

thanks
