奇异配方的％files部分非直观地将文件复制到错误的绑定位置

如何解决奇异配方的％files部分非直观地将文件复制到错误的绑定位置

我正在CentOS 8上工作，并且正在使用奇点3.6.2。我有一个奇点配方文件：

BootStrap: yum
OSVersion: 8
MirrorURL: http://mirror.centos.org/centos-8/8/BaseOS/x86_64/os/
Include: yum

%files
/gpfs0/home1/group/user/path/to/some.rpm /tmp

%post
    ls /tmp
    echo "Hello from inside the container"

当我跑步时：

$ sudo singularity build test.simg tmp
INFO:    Starting build...
INFO:    Skipping GPG Key Import
INFO:    Adding owner write permission to build path: /tmp/rootfs-4db1e756-22a8-11eb-bb20-34800d2d90f0
INFO:    Copying /gpfs0/home1/group/user/path/to/some.rpm to /tmp/rootfs-4db1e756-22a8-11eb-bb20-34800d2d90f0/tmp
INFO:    Running post scriptlet
+ ls /tmp
qtsingleapp-RStudi-c679-6387e228-lockfile
rootfs-4db1e756-22a8-11eb-bb20-34800d2d90f0
rootfs-b10ad12c-229a-11eb-85a3-34800d2d90f0
+ echo 'Hello from inside the container'
Hello from inside the container
INFO:    Creating SIF file...

根据奇点documentation

在默认配置中，系统默认绑定点为$ HOME，/ sys：/ sys，/ proc：/ proc，/ tmp：/ tmp，

问题：

1. 为什么%files部分将我的rpm放在/tmp/rootfs-4db1e756-22a8-11eb-bb20-34800d2d90f0/tmp而不是/tmp中？这似乎与文档相矛盾。这也与奇点v2.5.1观察到的行为不同

2. 此外，我将如何访问该文件。路径中较长的类似于哈希的部分似乎会根据构建而改变？

解决方法

我没有使文档与%files部分实际放置文件的位置一致的答案，但是对于如何访问复制的文件，我确实有一个答案。您需要在${SINGULARITY_CONTAINER}部分中使用%post。

例如

$ cat Singularity
BootStrap: yum
OSVersion: 8
MirrorURL: http://mirror.centos.org/centos-8/8/BaseOS/x86_64/os/
Include: yum

%files
# Will need to use environmental variables to copy the code to
/gpfs0/home/group/user/path/to/some.rpm /tmp

%post
    ls ${SINGULARITY_CONTAINER}/tmp
    echo "Hello from inside the container"

建立收益时：

$ sudo singularity build tmp.simg tmp
INFO:    Starting build...
INFO:    Skipping GPG Key Import
INFO:    Adding owner write permission to build path: /tmp/rootfs-e2a3fbb4-242b-11eb-a267-34800d2d90f0

INFO:    Running post scriptlet
+ ls /tmp/rootfs-e2a3fbb4-242b-11eb-a267-34800d2d90f0/tmp
some.rpm
+ echo 'Hello from inside the container'
