buildah-无法在PATH中找到Python可执行文件集

如何解决buildah-无法在PATH中找到Python可执行文件集

我正在尝试构建基本图像并执行Python Django Web应用程序的容器。我已经执行了以下步骤，但是当我尝试运行容器时，它抛出一条错误消息，指出未找到python3.8可执行文件。你能不能让我知道我是否在这里想念任何东西。当我尝试在容器中检查时，我可以看到它们存在python可执行文件

[root@fed32 ~]# buildah from fedora
[root@fed32 ~]# buildah run fedora-working-container -- dnf -y install python3.8
[root@fed32 ~]# buildah run fedora-working-container -- dnf -y install pip
[root@fed32 ~]# buildah run fedora-working-container -- pip install Django
[root@fed32 ~]# buildah run fedora-working-container -- mkdir -p /home/admin/Django_Projects
[root@fed32 ~]# buildah config --workingdir /home/admin/Django_Projects fedora-working-container
[root@fed32 ~]# buildah run fedora-working-container -- django-admin startproject mysite
[root@fed32 ~]# buildah config --workingdir /home/admin/Django_Projects/mysite fedora-working-container
[root@fed32 ~]# buildah config --env PATH=$PATH:/usr/bin/python3.8 fedora-working-container
[root@fed32 ~]# buildah config --cmd '["/usr/bin/python3.8","manage.py","runserver"]' fedora-working-container
[root@fed32 ~]# buildah config --port 8000 fedora-working-container
[root@fed32 ~]# buildah commit fedora-working-container hellodjango

Error - 
[root@fed32 ~]# podman run -dt -p 8000:8000 localhost/hellodjango
Error: executable file `[/usr/bin/python3.8,` not found in $PATH: No such file or directory: OCI runtime command not found error

[root@fed32 ~]# buildah run fedora-working-container -- /bin/bash
[root@f283758d9ad2 Django_Projects]# 
[root@f283758d9ad2 Django_Projects]# whereis python3.8
python3: /usr/bin/python3.8 /usr/bin/python3 /usr/lib/python3.8 /usr/lib64/python3.8 /usr/local/lib/python3.8 /usr/include/python3.8
[root@f283758d9ad2 Django_Projects]# ls -ltr /usr/bin/python3.8
-rwxr-xr-x. 1 root root 15536 Aug 13 11:53 /usr/bin/python3.8
[root@f283758d9ad2 Django_Projects]# echo $PATH
/root/.local/bin:/root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/bin/python3.8

解决方法

关于如何传递cmd参数存在语法问题。我可以通过如下修改cmd来解决此问题。

之前-

[root@fed32 ~]# buildah config --cmd '["/usr/bin/python3.8","manage.py","runserver"]' fedora-working-container

之后-

[root@fed32 ~]# buildah config --cmd '"/usr/bin/python3.8" "manage.py" "runserver"' fedora-working-container
