Cloud-builders: Baffling behavior of args when building go binary

[ernsheong]

Hi all,

The following works:

steps:
- name: 'gcr.io/cloud-builders/go'
  args: ['build', '-o', 'main', '-v', '-ldflags', '"-d"', '-a', '.']

But adding an additional flag to -ldflags does not:

steps:
- name: 'gcr.io/cloud-builders/go'
  args: ['build', '-o', 'main', '-v', '-ldflags', '"-d -w"', '-a', '.'] # Added -w flag in flag list

returns flag provided but not defined: -d -w But the -w flag is listed...

Is this expected behaviour? What is the alternative?

Instead of '"-d -w"', use '-d -w'. The quotes you provided are to help the shell figure out that -d and -w go together, but inside cloud build there is no actual shell - just the yaml parser, so '-d -w' is sufficient.

Interesting. Thank you!
