docker - 将 ffmpeg 添加到 docker(Alpine 基础镜像)

Question

我正在尝试将 FFmpeg 添加到具有 Alpine 基础镜像的 docker 容器中。我收到此错误

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

这是我的 docker 文件

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"]

我究竟做错了什么？

Answer 1

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