ghcr.io/cross-rs/cross:main shows wrong version (without commit info)

[AndreyMZ]

Problem description

cross in the Docker image ghcr.io/cross-rs/cross:main shows wrong version (0.2.5, without commit info).

Impact

This version is used as the default version for build images:

cross/src/docker/shared.rs

Lines 29 to 33 in 4090bec

	pub const DEFAULT_IMAGE_VERSION: &str = if crate::commit_info().is_empty() {
	env!("CARGO_PKG_VERSION")
	} else {
	"main"
	};

So, outdated build images are used. For example, ghcr.io/cross-rs/x86_64-unknown-linux-gnu:0.2.5 is used instead of ghcr.io/cross-rs/x86_64-unknown-linux-gnu:main.

Steps to reproduce

docker pull ghcr.io/cross-rs/cross:main
docker run -it ghcr.io/cross-rs/cross:edge cross --version

Actual result

$ docker run -it ghcr.io/cross-rs/cross:edge cross --version
cross 0.2.5

Expected result

$ docker run -it ghcr.io/cross-rs/cross:edge cross --version
cross 0.2.5 (4090bec 2024-10-15)

Workaround

Configure build images explicitly for every target:

• in "Cargo.toml":

  [package.metadata.cross.target.x86_64-unknown-linux-gnu]
  image = "ghcr.io/cross-rs/x86_64-unknown-linux-gnu:main"

• or using environment variables:

  CROSS_TARGET_X86_64_UNKNOWN_LINUX_GNU_IMAGE=ghcr.io/cross-rs/x86_64-unknown-linux-gnu:main
