I want to update path from python script i-e add /tmp in $PATH. Reason is I am using aws lambda and it looks for aws-iam-authenticator binary. Now this binary has to be in $PATH otherwise it throws error:

[Errno 2] No such file or directory: 'aws-iam-authenticator': 'aws-iam-authenticator'

Since only /tmp is writeable in aws-lambda I can not move this binary to any other /bin/* or PATH dir.

I tried doing this: 

subprocess.call('PATH=$PATH:/tmp/',shell=True)

But it doesn't work.

Lambda path: PATH=/var/lang/bin:/usr/local/bin:/usr/bin/:/bin:/opt/bin

    >>> import os >>> os.environ["PATH"]+="/dodo/" >>> print os.environ["PATH"] This seems to work Commented Jan 25, 2019 at 14:03

    That's a pretty bad idea imo. That would that any program you put in your tmp folder will be in your PATH which may lead to problems when resolving executable real path. A better way to solve your issue would be to move the aws-iam-authenticator binary to a folder in your path (/opt/bin for instance). You may need to play around with chmod and chown.

    Why don't you just invoke the executable using the full path? /tmp/aws-iam-authenticator Commented Jan 25, 2019 at 15:29

    If you script relies on aws-iam-authenticator, why are you installing it to /tmp, rather than somewhere already accessible? Commented Feb 23, 2020 at 14:53
