Hi, I think everything has been explained in the README.md file.

Thanks

This needs to run as a non root user and to write to /tmp/ only. Please can you take a look?

[psyhomb]

Hey @alexellis, function is using in memory file object, in other words it doesn't require filesystem access, so I'm not quite sure what do you mean by it has to write to /tmp?

[alexellis]

Ok then please just make sure you use a non root user next.

[psyhomb]

Will do that ASAP, thanks.

[psyhomb]

Ok then please just make sure you use a non root user next.

Done, all processes running inside of container will be executed under non root user.

[psyhomb]

Hey @alexellis is there anything else I have to change?

[psyhomb]

Hey @alexellis what is going on with this submission, is this suppose to take this long, it's been almost a month?

[alexellis]

The OpenFaaS project is run by unpaid volunteers. As the maintainer I receive hundreds of GitHub notifications per week, so it's hard to keep track of all of them.

I'll check your PR again.

The best way to get on my radar is to message in a public channel on Slack or to DM me there.

After deploying a function from the store, users will have no idea how to invoke your function. It's not your fault, but you could help them by providing a helper message when the user doesn't provide your expected input, or they give a non-JSON input.

What do you think?

[alexellis]

I'm also struggling to understand why the official Python template wasn't used for the function? I'd rather it was based upon something which is being maintained by the project.

Let us know on Slack if you need any technical support with templates or building custom modules.

What about repo_url link to full documentation?

Development of imgmod function was started 2 years ago, at that time python3 template didn't even exist, I've also sent you python3 template suggestion on Slack at that time... so that's the reason why 🙂.

I'd rather it was based upon something which is being maintained by the project.

This function is tested and it's working on OpenFaaS and AWS Lambda platform/service, is there any kind of issue you've detected?
