Re: [ceylon-users] Ceylon application in Docker, Help!

[Tako Schotanus]

These lines where the COPY happen seem fishy:

    ./modules/docker/example/1.0.0/com.docker.example-1.0.0.car

There should be a "/com/" in there. It should be:

    ./modules/com/docker/example/1.0.0/com.docker.example-1.0.0.car

HTH,

Hi Guys, Im trying to run spring application (Ceylon) with docker, but i'm not able to run any ceylon module inside the container. To demonstrate what is my problem i have an example. You can find it here https://github.com/voiii/ceylon-docker-example . This is simple ceylon module containing single run.ceylon file which should output "Hello From docker!"

I build ceylon example module running 

ceylon compile

The effect is 

Note: Created module com.docker.example/1.0.0

 

I moved out the modules out of the project to "simulate" docker env. I have put it in previous mentioned repository. I "cd" to repository main directory. ls -al output

I also have Dockerfile but this will be used next.

I run 

ceylon run com.docker.example

And i get expected output. 

Hello From docker!

(this is my mac operating system run, so it is not run from docker yet) 

I want to build a Docker image now, so i have Dockerfile 

FROM ceylon/ceylon

WORKDIR /srv

COPY ./modules/* modules

RUN find .

CMD ceylon run com.docker.example

What happens here:

- I use latest Ceylon image as a source (is it correct?).

- I have /srv directory as working dir. 

- I'm copping ./modules directory from my operating system  to docker image /srv/modules

- I want to be sure that modules in srv so i "find ." to find out what is in /srv (workdir)

- Docker run, should run ceylon run com.docker.example from working directory /srv (am i correct?)

I build an image

docker build -t example ./

I have na image. As You can see /srv/modules contains example module. 

I run the docker image

I get output 

docker run example

ceylon run: Module com.docker.example not found in the following repositories:

 /usr/share/ceylon/1.3.3/repo

 /srv/modules

 /app/.ceylon/cache

 https://modules.ceylon-lang.org/repo/1

 [Maven] Aether

 [NPM] npm

 

WHY ??? I'm struggling with this several day now. Why "ceylon run" can't find this "com.docker.example" module. It was fine on my operating system. Why in docker it doesn't work ?? It should be run the same way. I have tried running this module from different working dir manipulating  ceylon  "--cwd" option but it doesn't work. I tried putting this module (with all directory structure above so "/com/example/docker...") in /app/.ceylon/cache, /usr/share/ceylon/1.3.3/repo. Still it doesn't work. 

Please HELP!
