将 NodeRED Docker 映像部署到 Heroku 失败，但本地构建没有错误

Question

我们正在尝试将基于 NodeRED 的 Docker 图像推送到 Heroku。本地构建和测试运行得很好，但是当我们将它部署到 Heroku 时，Docker 图像构建失败。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：

npm WARN saveError EACCES: permission denied, open '/usr/src/node-red/package.json'

我错过了什么？

澄清一下：

失败的地方：

heroku stack:set container
git push heroku master

它试图在 heroku 上构建容器

有效的方法：

heroku container:login
heroku container:push web --app insectos
heroku container:release web --app insectos

Answer 1

首先，将 settings.js 复制到 /usr/app/node-red/.node-red 不会执行任何操作，因为它会被忽略。 Node-RED Docker 容器的 usrDir 是 /data，因此需要将 settings.js 复制到那里。

其次，要安装额外的节点，请将它们添加到 /data 中的 package.json 而不是 /usr/src/node-red。然后运行 npm install ... 在 /data 目录中，这会将节点安装到 /data/node_modules.

如果要删除任何核心节点，则需要将它们的文件名包含在 settings.js 的 nodesExcludes 键中，如下所示：

...
nodesExcludes: [ '90-exec.js', '10-file.js'],
...
