我正在使用 Docker 创建一个 Next.js 项目,但每次运行时docker build
,docker 映像都是 300 MB+。我的目标是减小 docker 镜像的大小。为此,我开始使用zeit/pkg,但它不能正常工作。
问题:
Next.js 中需要哪些文件docker build
?(我在每个教程中都看到了COPY . .
)我怎样才能减小 docker 图像的大小?
Dockerfile:
FROM node:lts-alpine as build-env
WORKDIR /app
COPY . .
RUN yarn install --pure-lockfile --ignore-engines
ENV NODE_ENV=production
RUN yarn run build
RUN yarn run pkg
FROM node:alpine
RUN apk update && \
apk add --no-cache libstdc++ libgcc ca-certificates && \
rm -rf /var/cache/apk/*
WORKDIR /app
COPY --from=build-env /app/pkg .
ENV NODE_ENV=production
EXPOSE 8080
CMD ./next-app
