我有一个React应用程序在nginx容器中运行，如以下Dockerfile中所述。现在，我想在我的Dockerfile中添加一个HEALTHCHECK，看起来像这样：
HEALTHCHECK --interval=10s node /healthcheck.js
但是我不知道该怎么做。我是否需要在最终的Docker构建阶段中添加此运行状况检查？我猜nginx容器不能运行任何node命令？
还是我需要在“阶段1”中的某个地方添加健康检查？
Dockerfile

# Only rebuilds layer if package.json has changed.

# Stage 1 - Build the application using cached node layer
FROM node:10-alpine AS build-stage

COPY --from=node_cache /cache/ .
COPY . ./

# Stage 2 - Create the production image containing the compiled app only
FROM nginx:1.15-alpine
