每当我尝试使用我放置的包装脚本来构建我的 Docker 映像时，我都会遇到一个问题，该脚本允许使用主机环境变量进行适当的 ENV 替换。

每当我执行我的脚本时，我都会收到错误消息：

这是包装脚本

#!/bin/env bash
# Make sure you have the appropriate token in your ENV variables on a machine that you're running this script on.
DOCKER_BUILDKIT=1 docker build --no-cache  -f <(envsubst < ./Dockerfile) -t "my-image" .
docker run -d -t my-image $1

这是Dockerfile：

FROM fluxcd/fluxctl:1.24.3 as builder

ARG ARCH=linux/amd64
ARG KUBECTL_VER=1.22.2
ARG GH_CLI_VER=2.2.0

RUN curl -sL https://storage.googleapis.com/kubernetes-release/release/v${KUBECTL_VER}/bin/${ARCH}/kubectl \
    -o /usr/local/bin/kubectl && chmod +x /usr/local/bin/kubectl

RUN curl -sL https://github.com/cli/cli/releases/download/v${GH_CLI_VER}/gh_${GH_CLI_VER}_linux_amd64.tar.gz \
    | tar xvz -C /tmp && mv /tmp/gh_${GH_CLI_VER}_linux_amd64/bin/gh /usr/local/bin/ && chmod +x /usr/local/bin/gh && \
    rm -rf /tmp/gh_*

FROM k8s.gcr.io/git-sync/git-sync:v3.3.5 as gitsync

FROM alpine:3.14 as gtk-cli

RUN apk update && apk add coreutils git
ENV GITHUB_TOKEN=$GITHUB_TOKEN

COPY --from=builder --chmod=755 /usr/local/bin/kubectl /usr/local/bin/

COPY --chmod=755 ./ssh-entrypoint.sh /ssh-entrypoint.sh
COPY --chmod=755 ./docker-entrypoint.sh /docker-entrypoint.sh

RUN kubectl version --client=true && fluxctl version && gh version
WORKDIR /
ENTRYPOINT [ "/docker-entrypoint.sh" ]

我真的很感激这里的一些帮助。

谢谢大家！
