我正在尝试运行chrome容器。
这对我有效：
[practice]$ docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome
b7d63881869721fe66a4f00de4be7a3bfb8e922410776a7c35f827bfd08f9455
[practice]$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b7d638818697 selenium/standalone-chrome "/opt/bin/entry_poin…" 22 seconds ago Up 22 seconds 0.0.0.0:4444->4444/tcp lucid_sammet
但我的要求是在我的容器中有一个额外的包，所以我创建了一个DockerFile
FROM selenium/standalone-chrome
FROM node:latest
RUN npm install --save @ffmpeg-installer/ffmpeg
并使用创建了一个构建：
[practice]$ docker build -t mychrome:1.0 .
Sending build context to Docker daemon 15.34MB
Step 1/3 : FROM selenium/standalone-chrome
---> c84475653f71
Step 2/3 : FROM node:latest
---> a511eb5c14ec
Step 3/3 : RUN npm install --save @ffmpeg-installer/ffmpeg
---> Using cache
---> 2d04ced6065c
Successfully built 2d04ced6065c
Successfully tagged mychrome:1.0
但当我创建容器时，它会被自己杀死。
[practice]$ docker run -d -p 4444:4444 -v /dev/shm:/dev/shm mychrome:1.0

请告诉我这里出了什么问题。
通过使用以下dockerfile:使其工作
FROM node:latest AS node_base
RUN echo "NODE Version:" && node --version
RUN echo "NPM Version:" && npm --version
RUN npm install --save @ffmpeg-installer/ffmpeg
RUN echo "NPM Modules:" && npm ls
FROM selenium/standalone-chrome
USER root
COPY --from=node_base . .
RUN echo "NPM Modules:" && npm ls
RUN echo "file ends..."
