To reduce the Docker image size, it's a good practice to clean up the apt cache after installing packages. You can do this by adding && rm -rf /var/lib/apt/lists/* to the end of this RUN command.

RUN apt-get update && apt-get install -y \
    curl git build-essential pkg-config libsystemd-dev && \
    rm -rf /var/lib/apt/lists/*


ARG GO_VERSION=1.24.9
RUN curl -fsSL https://go.dev/dl/go${GO_VERSION}.linux-$(dpkg --print-architecture).tar.gz -o go.tar.gz && \
tar -C /usr/local -xzf go.tar.gz && rm go.tar.gz
ENV PATH="/usr/local/go/bin:${PATH}"
