I am trying to execute a Python script on Windows server 2016. I have Win32-OpenSSH installed on Windows server. The python script expects two environment variables (
BITBUCKET_BRANCH) to be present. These are already set by default in the Bitbucket pipeline. The python script is copied to the remote server and then using SSH, i invoke it from the Bitbucket pipeline.
When I was trying the following command in my Bitbucket pipeline...
scp <copy_python_script_to_win_server> # Works fine echo $BITBUCKET_REPO_SLUG # Prints the repo name echo $BITBUCKET_BRANCH # Prints the branch name ssh email@example.com 'C:/Python/bin/python.exe C:/Users/john.doe/deploy.py' >> ./cmd_output echo $? cat ./cmd_output
...I was getting the following error:
Traceback (most recent call last): File "C:/Users/john.doe/deploy.py", line 16, in <module> print(os.environ['BITBUCKET_REPO_SLUG']) File "C:\Python\lib\os.py", line 669, in __getitem__ raise KeyError(key) from None KeyError: 'BITBUCKET_REPO_SLUG'
It seemed to me that the Bitbucket environment variables were not getting passed to the python script (most probably because I was not running it from the pipeline itself but because i was invoking it on a remote server). So keeping everything else as is, I only changed the
ssh command to the following:
ssh firstname.lastname@example.org 'set BITBUCKET_REPO_SLUG=$BITBUCKET_REPO_SLUG; set BITBUCKET_BRANCH=$BITBUCKET_BRANCH; C:/Python/bin/python.exe C:/Users/john.doe/deploy.py' >> ./cmd_output
With the above change, the pipeline shows successful build and the return status (
$?) always prints 0. Also,
cat ./cmd_output prints nothing. As you can expect, on the Windows server, the python script doesn't really runs.
import os ... print(os.environ['BITBUCKET_REPO_SLUG']) print(os.environ['BITBUCKET_BRANCH']) ... ...
I'm not sure what exactly am i doing wrong. Any help will really be appreciated.
