我一直在尝试创建自己的busybox基础镜像。
# ./mkimage.sh -t pensu/busybox busybox-static
+ mkdir -p /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs
+ tar --numeric-owner -caf /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs.tar.xz -C /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs '--transform=s,^./,,' .
+ cat > '/var/tmp/docker-mkimage.US3tHy0uBQ/Dockerfile'
+ rm -rf /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs
+ docker build -t pensu/busybox /var/tmp/docker-mkimage.US3tHy0uBQ

我可以看到我的Docker仓库中有可用的镜像。
# docker images

但是当我尝试运行docker时,总是会出现错误:
# docker run -it pensu/busybox /bin/sh
exec: "/bin/sh": stat /bin/sh: no such file or directorytime="2015-04-09T16:03:45+05:30" level="fatal" msg="Error response from daemon: Cannot start container 8fe73b7832193c847d7975175a4be86d1f0b550b6a00b812bd4cdd18fe752468: exec: \"/bin/sh\": stat /bin/sh: no such file or directory"
我不明白为什么会出现那个错误?我做错了什么吗?我还有哪些方法可以验证我创建的图像是否是正常工作的?
WORKDIR
,而且我使用了COPY . .
命令,它使用了我的本地./bin
来覆盖容器中的/bin
目录。 - undefined
