COPY失败：stat / var / lib / docker / tmp / docker-builder700869788 / private：无此类文件或目录

Question

我收到一个错误：

COPY失败：stat / var / lib / docker / tmp / docker-builder700869788 / private：无此类文件或目录。

我在Dockerfile中写道：

FROM "centos"

    RUN mkdir ~/.ssh
    COPY ./private ~/.ssh/id_rsa
    RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
    RUN yum install -y wget
    RUN yum update -y

当我跑步时docker build ./ -t docker/app，出现错误：

Status: Downloaded newer image for centos:latest
 ---> ff426288ea90
Step 2/22 : RUN mkdir ~/.ssh

Step 3/22 : COPY ./private ~/.ssh/id_rsa
COPY failed: stat /var/lib/docker/tmp/docker-builder700869788/private: no such file or directory  .

当然，私钥在我的PC中，现在这个Dockerfile在myname / Desktop / app / Dockerfile中，而私密ket在〜/ .ssh / id_rsa中，这个错误意味着目录错误吗？

Answer 1

您应该将该文件与 Dockerfile 放在同一目录中。
