How to get user input in Docker with Go
问题
main.go
package main
import (
"bufio"
"os"
"time"
)
func main() {
code, err := bufio.NewReader(os.Stdin).ReadString('\n')
if err != nil {
panic(err)
}
time.Sleep(time.Second * 10)
}
Dockerfile
FROM golang:1.17
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app
CMD ["go","run","main.go"]
创建并运行 Docker 容器时出现错误，如下图所示：
我想在运行 Docker 容器时从终端获取用户输入。
英文:

package main
import (
"bufio"
"os"
"time"
)
func main() {
code, err := bufio.NewReader(os.Stdin).ReadString('\n')
if err != nil {
panic(err)
}
time.Sleep(time.Second * 10)
}
Dockerfile

通过使用ENTRYPOINT而不是CMD，您的用户可以在docker run命令之后传递参数：
ENTRYPOINT ["echo", "Hello World"]
docker run <container-name>
> Hello World
docker run <container-name> test
> Hello World test
但是，您应该使用os.Args来检索这些参数。
英文:
By using ENTRYPOINT instead of CMD your user could pass parameters after the docker run command:
ENTRYPOINT ["echo", "Hello World"]
docker run <container-name>
> Hello World
docker run <container-name> test
> Hello World test
However you should use os.Args to retrieve those argument.
