尝试使用 golang 和 react 代码构建 docker 镜像。未设置环境变量 JWT_SECRET_KEY。
# Build the Go API
FROM golang:latest AS builder
ADD . /app
WORKDIR /app/server
ENV JWT_SECRET_KEY=DefaultKey
RUN go mod download
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags "-w" -a -o /main .
# Build the React application
FROM node:alpine AS node_builder
COPY --from=builder /app/client ./
RUN npm install
RUN npm run build
# Final stage build, this will be the container
# that we will deploy to production
FROM alpine:latest
RUN apk --no-cache add ca-certificates
COPY --from=builder /main ./
COPY --from=node_builder /build ./web
RUN chmod +x ./main
EXPOSE 8080
CMD ./main
为了构建它,我运行了命令
docker build -t webapp .
如果您想JWT_SECRET_KEY
在生产阶段进行设置,则需要将其移动到该阶段。或者,如果您在两者中都需要它,请复制它。因此,将您的 docker 文件更改为
# Build the Go API
FROM golang:latest AS builder
ADD . /app
WORKDIR /app/server
RUN go mod download
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags "-w" -a -o /main .
# Build the React application
FROM node:alpine AS node_builder
COPY --from=builder /app/client ./
RUN npm install
RUN npm run build
# Final stage build, this will be the container
# that we will deploy to production
FROM alpine:latest
RUN apk --no-cache add ca-certificates
ENV JWT_SECRET_KEY=DefaultKey
COPY --from=builder /main ./
COPY --from=node_builder /build ./web
RUN chmod +x ./main
EXPOSE 8080
CMD ./main
