Bob builds and packages pip dependencies for your functions using a container compatible with the Binaris runtime environment. By default Bob outputs dependencies to $CWD/dist (dir is created if non-existent).
-
Create a Binaris Python2 or Python3 function using
bn create <python2|python3> foofunc -
Add your pip dependencies to a
requirements.txtfile in your function directory -
Run
/path/to/bob/build.sh <2|3>to build the dependencies listed inrequirements.txtfor the specified python version -
bn deploy foofunc
Step 3 should be repeated anytime requirements.txt is modified or changed
You can substantially reduce build times by running
cp requirements.txt oldrequirements.txt
which allows your existing dependencies to be cached on subsequent builds.
Bob looks for the optional file oldrequirements.txt in the same directory where requirements.txt resides.
oldrequirements.txt can be viewed as a stable-state or checkpoint for pip dependencies listed in requirements.txt.
If the file is defined, Bob will build a cached state from the oldrequirements.txt dependencies which future module installations can utilize before fetching from the remote registry. In other words, on subsequent builds only the modules that are listed in requirements.txt and NOT listed in oldrequirements.txt will be fetched and downloaded.
