# Mounting-Local-Files

DO NOT INCLUDE THE BELOW - IT'S FOR YOU, DELETE WHEN DONE
----
* You have a good user scenario below, keep it.
* Talk about taking the existing code from xxx and applying it to auto uploading to IPFS
* ...

What should happen:
- All files identified by the glob are converted (internally) into strings and attached to environment variables (use base64)
- These environment variables are run inside the docker container
- The first thing done inside the docker container is convert the files back to the original file names and filled with the original file content
- Then the command is run

What Vedant needs to do:
- Please rewrite this in correct grammar about what the problem is, what you want to do and how to solve it
- Discuss the various options you've thought about with pros/cons
- Talk about your proposed solution and the risks
- Add a note about the fact that context in WASM is doing something scary and we should change it

Adding scripts to IPFS and then mounting that script to run the script is a two step process

instead of this which requires 2 steps: upload your scripts to IPFS and then run the command

$ ipfs add hello.R
added QmQRVx3gXVLaRXywgwo8GCTQ63fHqWV88FiwEqCidmUGhk hello.R
 20 B / 20 B [=====================================================================================================================================================] 100.00%

bacalhau docker run \
 -v QmQRVx3gXVLaRXywgwo8GCTQ63fHqWV88FiwEqCidmUGhk:/hello.R \
 r-base \
-- Rscript hello.R

instead this could be replaced by this

bacalhau docker run r-base -v hello.R:/hello.R -- Rscript hello.R

Luke’s suggestions

you could add support for "mounting" local files via the same mechanism used for uploading files in the python WASM backend, it can be a local file, so you can reuse that code (uploading the context as a tar file), so docker run -v $(pwd)/file:/file cat /file you'd expect this to work
making -v work with local paths would be the cleanest thing IMO
because that's no additional flags and it's also the same as how docker works
if cids can't have a / as the first character, you could just switch on that
(and always require an absolute path)
or support ./foo but I think docker doesn't

it it could use a configurable publisher

Other additions to this include

when we calculate the CID of a file/folder, if some file/folder are there on IPFS we don’t add them to IPFS ?

Other possible solutions

Instead of mounting local paths we can have a --upload path which uploads the pwd

There are too many flags currently this might confuse users instead we should use the --context-path flag in the python wasm backend
