A0-2962: Dockerfile

[mgralinski-bright]

I was trying to create a docker file where I could run ink-wrapper. For reasons unknown to me, ink-wrapper produces wrong output. I am attaching sample.zip where you will find everything to reproduce the issue.

Thanks for the report, I'll look into it!

The problem seems to be with the version of rust you're using to install ink-wrapper. I believe this is related to an issue in a dependency of the library we use for code generation and the API it depends on, which is now being changed in nightly rust (udoprog/genco#39). For now, I'd recommend installing with:

cargo +nightly-2023-04-16 install ink-wrapper --locked --version 0.5.0

to basically lock the toolchain you're using to compile ink-wrapper to one that's known to work (I checked, and this one indeed works). I'll add a note about this to the README, and in the future, I hope the relevant changes will just be released into rust proper, so we can set min rust version and it will just work automatically or fail with an appropriate message.

Please let me know if this solves your problem, or open another issue if you have any other problems.

Installing ink-wrapper with fixed version nightly-2023-04-16, solved the issue. Thanks!
