exec-wrapper can't write files into /workspace folder in Cloud Build #205
Description
Trying to run a Cloud Build file like the next:
steps:
- name: 'gcr.io/google-appengine/exec-wrapper'
id: TEST
args:
[
'-i',
'gcr.io/$PROJECT_ID/${_BUILD_TARGET}',
'-s',
'${_CLOUD_SQL_DEV}',
'-e',
'DJANGO_SETTINGS_MODULE=${_DJANGO_SETTINGS}',
'-e',
'CLOUD_SQL=/cloudsql/${_CLOUD_SQL_DEV}',
'--',
'bash',
'-c',
'touch /workspace/test.txt',
]
Is throwing an error, as it can't write in the /workspace folder:
touch: cannot touch '/workspace/test.txt': Permission denied
It would be great if the workspace directory and/or any other volume defined in the step were mapped directly, but it could also be a good option to accept volumes as parameters with the -v option. Something like
- name: 'gcr.io/google-appengine/exec-wrapper'
id: TEST
args:
[
'-i',
'gcr.io/$PROJECT_ID/${_BUILD_TARGET}',
'-s',
'${_CLOUD_SQL_DEV}',
'-e',
'DJANGO_SETTINGS_MODULE=${_DJANGO_SETTINGS}',
'-e',
'CLOUD_SQL=/cloudsql/${_CLOUD_SQL_DEV}',
'-v',
'/workspace:/workspace',
'--',
'bash',
'-c',
'touch /workspace/test.txt',
]
