I want to build a docker image for my substrate node

Question

Now I am building a new docker image for my substrate node

Docker version 24.0.5, build ced0996

Node version v18.16.1

I am using this Dockerfile.dev to build the docker image.

FROM paritytech/ci-linux:production as build

WORKDIR /code
COPY . .
RUN cargo build --release

FROM ubuntu:22.04
WORKDIR /node

# Copy the node binary.
COPY --from=build /code/target/release/node-template .

# Install root certs, see: https://github.com/paritytech/substrate/issues/9984
# RUN apt update && \
#     apt install -y ca-certificates && \
#     update-ca-certificates && \
#     apt remove ca-certificates -y && \
#     rm -rf /var/lib/apt/lists/*

EXPOSE 9944
CMD [ "./node-template", "--dev" ]

By the way, I got this error and couldn't figure it out.

254.9 info: installing component 'rustfmt'

Any kind of answers would be appreciated.

Thanks in advance.

Seems like this commit (#98f2e345) might no longer exist or you have a corrupt git registry.

After cloning the repo and checking, the commit does exist in the repository.

You can try deleting the cargo.lock or clearing the registry.
