Adding ffmpeg to to docker(Alpine base image)

Question

我正试图将FFmpeg添加到我的docker容器中。我得到这个错误

[2021-10-26 13:45:42] yarn: Invalid argument

这是我的dockerfile

FROM node:erbium-alpine
ARG NODE_ENV=development
ENV NODE_ENV=${NODE_ENV}
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app/
RUN apk upgrade -U  
&& apk add ca-certificates ffmpeg libva-intel-driver 
&& rm -rf /var/cache/*
RUN yarn install --frozen-lockfile && 
yarn cache clean
EXPOSE 3030
ENTRYPOINT ["/usr/bin/ffmpeg"] 
CMD ["yarn", "start"]

我做错了什么?

Answer 1

通过删除ENTRYPOINT修复它，因为我意识到我不需要它。在我的代码中，我将ffmpeg旋转为子进程
