【问题描述】：
我们正在尝试将基于 NodeRED 的 Docker 镜像推送到 Heroku。本地构建和测试运行起来就像一个魅力，但是当我们将它部署到 Heroku 时，Docker 镜像构建失败。我们的 docker 文件非常简单：
FROM nodered/node-red
USER node-red
# Copy package.json to the WORKDIR so npm builds all
COPY package.json .
RUN mkdir -p node-red-static
COPY node-red-static/ node-red-static/
COPY defaults .
# NodeRED configuration
COPY .node-red/settings.js /usr/src/node-red/.node-red/settings.js
COPY .node-red/flows.json /data/flows.json
COPY package.json /usr/src/node-red/package.json
# Actual installation
RUN npm install --unsafe-perm --no-update-notifier --no-fund --only=production
（我也试过不设置用户）
heroku.yml:
build:
docker:
web: Dockerfile
git push heroku master 上的错误：

我错过了什么？
更新

澄清一下：
什么失败了：
heroku stack:set container
git push heroku master
尝试在heroku上构建容器
什么有效：
heroku container:login
heroku container:push web --app insectos
heroku container:release web --app insectos
【问题讨论】：
-
您要复制到
/usr/src/node-red目录的package.json中有什么内容？你不应该真的改变这个文件。所有的定制都应该在/data中。同样settings.js也应该放在/data -
package.json 包含我们使用的定制节点列表。删除了我们不使用的那些。添加了我们使用的那些。这是一个运行时部署
-
编辑问题以显示该文件，但这是要更改的错误文件，它应该是
/data中的那个 -
好的，我看到你已经完全改变了
/usr/src/node-red/package.json中的默认scripts部分。考虑到更改的数量，可能不再值得使用官方节点红色图像作为基础，因为您基本上忽略了它设置的所有内容。 -
我会把东西改回来，而不是重新发明轮子。感谢您的帮助！
