I am having difficulty building the project from the template using cargo +esp build --release .

I built a docker container using

FROM ubuntu:focal

RUN apt clean

RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y \
    git \
    curl \
    gcc \
    clang \
    ninja-build \
    cmake \
    libudev-dev \
    unzip \
    xz-utils\
    python3 \
    python3-pip \
    python3-venv \
    libusb-1.0-0 \
    libssl-dev \
    pkg-config \
    libtinfo5 \
    libpython2.7

RUN git clone https://github.com/esp-rs/rust-build.git
RUN cd rust-build && \
    curl -LO https://github.com/esp-rs/rust-build/releases/download/v1.62.1.0/install-rust-toolchain.sh && \
    chmod a+x install-rust-toolchain.sh && \
    ./install-rust-toolchain.sh

#RUN rustup update

ENV PATH=/root/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
RUN echo $PATH

RUN cargo install cargo-generate

Inside that container I ran

# cargo generate --vcs none --git https://github.com/esp-rs/esp-idf-template

Do you have any suggestions for how to build the template application?

I banged on it with a rock until I figured out what the problem was.

I had to switch to
./install-rust-toolchain.sh --export-file export-esp-rust.sh
And then I could
. /rust-build/export-esp-rust.sh ; cargo +esp build

It seems the --export-file was not listed in the Installation commands primary example from https://github.com/esp-rs/rust-build .
