Lambda package on Linux container results in "Failed to find the "zip" utility program in path. This program is required to maintain Linux file permissions in the zip archive."

[mrserverless]

Steps to reproduce the issue

1. Shell into any dotnet linux container, i.e: docker run -w /app -v $PWD:/app -ti microsoft/dotnet:2.0-sdk /bin/bash
2. Run Lambda package command: dotnet lambda package --configuration release --framework netcoreapp2.0 --output-package bin/release/netcoreapp2.0/deploy-package.zip
3. Sample code available here: https://github.com/serverless/serverless/tree/master/lib/plugins/create/templates/aws-fsharp with docker-compose: https://github.com/serverless/serverless/blob/master/docker-compose.yml

Expected behavior

Successful package:

Changed permissions on published dll (chmod +r Newtonsoft.Json.dll).
Zipping publish folder /app/bin/release/netcoreapp2.0/publish to /app/bin/release/netcoreapp2.0/deploy-package.zip
... zipping:   adding: Amazon.Lambda.Core.dll (deflated 57%)
... zipping:   adding: Newtonsoft.Json.dll (deflated 60%)
Created publish archive (/app/bin/release/netcoreapp2.0/deploy-package.zip).
Lambda project successfully packaged: /app/bin/release/netcoreapp2.0/deploy-package.zip

Actual behavior

Failure to find zip:

Changed permissions on published dll (chmod +r Newtonsoft.Json.dll).
Zipping publish folder /app/bin/release/netcoreapp2.0/publish to /app/bin/release/netcoreapp2.0/deploy-package.zip
Failed to find the "zip" utility program in path. This program is required to maintain Linux file permissions in the zip archive.

Additional information (e.g. issue happens only occasionally)

Basically to work around this, I need to

1. Install zip myself with apt -y install zip first OR
2. Create a separate docker image inheriting from dotnet-sdk:2.0 and install zip

zip command should be part of this image in order to support the dotnet commands that are offered.

Closing since this is addressed in a more appropriate PR https://github.com/aws/aws-lambda-dotnet/pull/238

@mrserverless, hey, I'm still getting this error when running lambda package on .net6 image. I need a lambda zip package. How can I achieve that?

[olevezinho]

Not sure if this might help @SangI762, @mrserverless. For future reference, this is basically Linux / macOS complaining about the non-existence of "zip" binaries. Most Linux distros come with unzip utility installed by default, but they don't contain the "zip" utility. Install that, and you should be fine.
