Docker build failing

[DavoSwain]

Having an issue with the docker build on the hello world example, getting the following feedback:

#9 5.446 Downloading vm_service 7.2.0...
#9 125.7 Connection closed before full header was received

executor failed running [/bin/sh -c dart pub get]: exit code: 69

Any suggestions on a fix?

I'd try again. Seems like a networking issue...

Also running into a docker build failure.
Steps to reproduce:

• Creating a helloworld application,
• Running dart run bin/server.dart works fine locally
• Running docker build . and after that docker run [container_name]

This error pops up:

standard_init_linux.go:228: exec user process caused: no such file or directory

Any thoughts?

On cloud deploy I get the following error (not sure if its the same of a different error)

[kevmoo]

I just did

docker build -t dart-server .
run -it --rm -p 8080:8080 --name myserver dart-server

no problem.

If you try to run /bin/sh or similar that will fail because that command does not exist in the compiled image. It's from scratch which is tiny

I'm also getting the "standard_init_linux.go:228: exec user process caused: no such file or directory" error message as reported by @Mooibroek above.

Steps to reproduce.

Run dartfn generate helloworld in a new folder.

As instructed by the README file. Run commands ...

docker build -t hello .
docker run -it -p 8080:8080 --name app hello

I'm on MacOS.

@Mooibroek If you created your project via the dartfn tool it may be that you've got a faulty docker file. Try and add a line similar to ...

COPY --from=0 /runtime/ /

to get the runtime needed by the server in the final runt-time Docker image.

We clearly need to fix something here...will take a look!

This is now fixed – thanks to @subfuzion – update dartfn and you should be good to go!
