Stdout of executed action not caught by tee

[davidferlay]

Context

Consider the log file of build command is generated by | tee by command like: set -o pipefail && ./plasmactl platform:build ${PLASMA_BUILD_ENV} ${PLASMA_BUILD_RESOURCES} --pw-base64 "${PLASMA_BUILD_PW_BASE64}" --use-volume-wd --remove-image | tee ${BUILD_LOG_FILE} && set +o pipefail

Observed

• Log file produced by tee contains only:

  Image "platform-actions-build:latest" doesn't exist locally, building...
  Step 1/10 : FROM alpine:3.18
  (...)
  Successfully built 7d5fd7c5231b
  Successfully tagged platform-actions-build:latest
  Flag "--use-volume-wd" is set. Copying the working directory inside the container.

• It does not contain the output of the command executed by launchrctl
• Issue not reproduced locally but only in CI, for unknown reason
• plasma_build_dev_711-plasma-core-contrib-custom (2).log

Expected

• Log file produced by tee should contains the entire stdout produced by launchrctl command: in this case, ansible-playbook output

Todo

I see a different solutions possible :

• Fix launchr tee output, but it's only reproduced in CI so it won't be easy to debug I guess
• Introduce a new option --log-output /some_file.log to launchrctl

I have a preference for last solution as it can be useful in other cases
