error on docker build

[4rutnv3g]

Hi there

On running sudo docker build github.com/docker-exec/lua.git I received the following output including an error message:

I am just starting out with docker so quite possibly this is entirely my error, just thought I'd let you know in case there is an issue here for you.

Cheers

Thanks for the report @4rutnv3g! These images are very old now and I need to update them all.

To help you out getting started with Docker, here's a minimal Dockerfile that contains lua:

FROM alpine:latest
RUN apk update && apk add lua5.3
ENTRYPOINT ["lua5.3"]

Save that as a Dockerfile somewhere then run this from that path:

docker build -t lua-test .

You can then run the image and pass scripts to it directly like this:

docker run -it --rm lua-test -e 'print("hello world")'

or mount scripts into the running container and evaluate them like this:

docker run -it --rm -v $PWD/foo.lua:/foo.lua lua-test /foo.lua

Hope that helps - I'm going to close this issue because for dexec's purposes the images don't need to be rebuilt, and there are a few related issues open in the dexec CLI repo: docker-exec/dexec#40, docker-exec/dexec#45 & docker-exec/dexec#62.

Good luck with your learning!
