问题描述
我从openjdk:8-jdk-alpine创建了一个docker镜像,但是当我尝试执行简单的命令时,出现以下错误:
I created a docker image from openjdk:8-jdk-alpine but when I try to execute simple commands I get the following errors:
RUN bash
/bin/sh: bash: not found
RUN ./gradlew build
env: can't execute 'bash': No such file or directory
推荐答案
Alpine docker image没有安装bash默认。您将需要添加以下命令来获取 bash
:
Alpine docker image doesn't have bash installed by default. You will need to add following commands to get bash
:
RUN apk update && apk add bash
如果您使用 Alpine 3.3 +
然后您就可以这样做
If youre using Alpine 3.3+
then you can just do
RUN apk add --no-cache bash
使docker映像尺寸较小。 (感谢@sprkysnrky的评论)
to keep docker image size small. (Thanks to comment from @sprkysnrky)
