Question

使用以下dockerfile：

FROM golang:1.9 AS build-go
RUN go get github.com/grafana/grafana; exit 0
WORKDIR $GOPATH/src/github.com/grafana/grafana
RUN go run build.go setup
RUN go run build.go build

FROM node:8 AS build-node
COPY --from=build-go $HOME/go/src/github.com/grafana/grafana .
RUN npm install -g yarn
RUN yarn install --pure-lockfile
CMD npm run watch
EXPOSE 3000

我创建并镜像，然后通过bash文件将其用于启动容器：

docker run -d -P --name=grafanabuildfromsrc myimg
docker exec grafanabuildfromsrc ./bin/linux-amd64/grafana-server

./bin/linux-amd64/grafana-server要求npm run build一次完成所有文件的构建。当前脚本将在构建完成之前执行它。

我想要的是在执行bash文件中的第二条命令之前，它应该等待容器内的命令首先完成。这可能吗？

一个重要的注意事项： grafana-server未完成时，"Failed to detect generated javascript files in public/build说npm run watch。

我该如何实现？

Answer 1

最简单的解决方案可能在npm run build之前运行npm run watch

Answer 2

扩展@AussiDan的答案，我将Dockerfile更改为：

FROM golang:1.9 AS build-go
RUN go get github.com/grafana/grafana; exit 0
WORKDIR $GOPATH/src/github.com/grafana/grafana
RUN go run build.go setup && go run build.go build

FROM node:8 AS build-node
COPY --from=build-go $HOME/go/src/github.com/grafana/grafana .
RUN npm install -g yarn && yarn install --pure-lockfile && npm run build
CMD ./bin/linux-amd64/grafana-server

EXPOSE 3000

因此，当我启动grafana服务器时，内置的javascript文件已在图像中。

如何等待命令在容器内完成执行
