方案

• 1. docker-squash
• 2. 删除RUN缓存
• 3. multi-stage

初始大小：

REPOSITORY          TAG                      IMAGE ID       CREATED      SIZE
easy_lib            latest                   2fb497e72891   2 days ago   16.4GB
minbull/easy_base   1.0.0                    edb431df719b   3 days ago   3.67GB
easy_base           latest                   edb431df719b   3 days ago   3.67GB
nvidia/cuda         10.0-devel-ubuntu18.04   c6abe772d510   5 days ago   2.24GB

E: Package 'libssl-dev' has no installation candidate

执行方案2后，大小：

easy_base_v1        latest                   fe5aa8e16df6   5 minutes ago       3.61GB

cmake处理后大小

easy_base_v1        latest    7663e43acf51   About a minute ago   3.58GB

cudnn的安装路径是什么

root@113a200d68d6:/usr/local# ls
bin  cuda  cuda-10.0  etc  games  include  lib  man  sbin  share  src

@lpj0822

[lpj0822]

/usr/lib/x86_64-linux-gnu/

[Vitah Lin]

cudnn所需文件：

root@113a200d68d6:/usr/lib/x86_64-linux-gnu# ll | grep cudnn
lrwxrwxrwx  1 root root        29 May 16 09:03 libcudnn.so -> /etc/alternatives/libcudnn_so
lrwxrwxrwx  1 root root        17 Apr 16  2019 libcudnn.so.7 -> libcudnn.so.7.5.1
-rw-r--r--  1 root root 356035144 Apr 16  2019 libcudnn.so.7.5.1
lrwxrwxrwx  1 root root        32 May 16 09:03 libcudnn_static.a -> /etc/alternatives/libcudnn_stlib
-rw-r--r--  1 root root 353886738 Apr 16  2019 libcudnn_static_v7.a

cudnn处理完大小：

easy_base_v1        latest    17640d8bf554   8 minutes ago       4.63GB

镜像更大了，有可能是因为多个COPY命令的问题

[Vitah Lin]

cudnn暂时不处理

[Vitah Lin]

主要问题解决依赖库的重复问题

[Vitah Lin]

依赖库的问题另建issue处理
