🐞 vim ENTRYPOINT is not honored in edge case with dagger

[artipfw]

What is the issue?

When using Dagger to run a container with a vim ENTRYPOINT, the expected behavior of launching the interactive vim editor does not occur. Instead, the shell opens without triggering vim, despite the ENTRYPOINT being defined in the Dockerfile.

Dagger version

dagger v0.18.9 (docker-image://registry.dagger.io/engine:v0.18.9) darwin/amd64

Steps to reproduce

1. Dockerfile

FROM alpine
RUN apk add --no-cache vim
ENTRYPOINT ["vim"]

2. Dagger Interactive Shell`

dagger -M

3. In Shell: Build Container

✔ container | build . | terminal
● Attaching terminal:
    container: Container!
    .build(
    │ │ context: Host.directory(path: "~/project/vim"): Directory!
    │ ): Container!

4. Observation

Dagger shell opens as:

dagger / $

5 If the check entrypoint, it is displayed

✔ container | build . | entrypoint 0.4s
vim

However, the entrypoint is not triggered as expected. You need to manually run Vim, even though it’s set as the ENTRYPOINT.

This is intentional - see #7136 for when this was changed, as well as the logic.
