如何进入 Dart Docker 容器的 shell？

Question

我正在尝试访问我的 Dart Docker 容器的 shell

$ docker-compose exec dartserver sh

但我收到此错误消息：

OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "sh": executable file not found in $PATH: unknown

有什么想法吗？

Dockerfile

FROM dart:stable AS build

# Resolve app dependencies.
WORKDIR /app
COPY pubspec.* ./
RUN dart pub get

# Copy app source code (except anything in .dockerignore) and AOT compile app.
COPY . .
RUN dart compile exe bin/server.dart -o bin/server

# Build minimal serving image from AOT-compiled `/server`
# and the pre-built AOT-runtime in the `/runtime/` directory of the base image.
FROM scratch
COPY --from=build /runtime/ /
COPY --from=build /app/bin/server /app/bin/

# Start server.
EXPOSE 8080
CMD ["/app/bin/server"]

scratch 图片默认没有 shell。如果你真的想访问shell，我建议使用busybox image.

参见busybox dockerfile:

FROM scratch
ADD busybox.tar.xz /
CMD ["sh"]

也是基于scratch的，但是shell启用了，另外还是很小
