云初始化上的 Azure 文件共享装载脚本

Question

我创建了一个Azure file share 并连接到它，我在azure 控制台中提供了一个脚本，如下所示

sudo mkdir /mnt/Totalvm
if [ ! -d "/etc/smbcredentials" ]; then
sudo mkdir /etc/smbcredentials
fi
if [ ! -f "/etc/smbcredentials/Totalcontainerstorage.cred" ]; then
    sudo bash -c 'echo "username=Totalcontainerstorage" >> /etc/smbcredentials/Totalcontainerstorage.cred'
    sudo bash -c 'echo "password=WPt39LGSSagFVeWbsNJ8HuhTaoPa1aiAZsOR3pBXnrOGjXFWVZj2BqooibIXvqbtjwbn4TLC4j+gJhOAk798pQ==" >> /etc/smbcredentials/Totalcontainerstorage.cred'
fi
sudo chmod 600 /etc/smbcredentials/Totalcontainerstorage.cred

sudo bash -c 'echo "//Totalcontainerstorage.file.core.windows.net/Totalvm /mnt/Totalvm cifs nofail,vers=3.0,credentials=/etc/smbcredentials/Totalcontainerstorage.cred,dir_mode=0777,file_mode=0777,serverino" >> /etc/fstab'
sudo mount -t cifs //Totalcontainerstorage.file.core.windows.net/Totalvm /mnt/Totalvm -o vers=3.0,credentials=/etc/smbcredentials/Totalcontainerstorage.cred,dir_mode=0777,file_mode=0777,serverino

我想在azure 的cloudinit 中使用这个脚本。我该怎么做，对此的任何帮助将不胜感激。

cloud-init 用于虚拟机的创建时间。因此，您可以在通过 CLI 命令创建 VM 时使用它，如下所示：

az vm create \
    --resource-group myResourceGroupAutomate \
    --name myAutomatedVM \
    --image UbuntuLTS \
    --admin-username azureuser \
    --generate-ssh-keys \
    --custom-data cloud-init.txt

但是这里有个问题。 cloud-init 脚本以“root”用户身份运行。所以你不需要使用sudo 模式。您可以像这样直接使用自定义用户数据格式：

$ cat mount_script.sh
#!/bin/bash
mkdir /mnt/Totalvm
if [ ! -d "/etc/smbcredentials" ]; then
mkdir /etc/smbcredentials
fi
if [ ! -f "/etc/smbcredentials/Totalcontainerstorage.cred" ]; then
    bash -c 'echo "username=Totalcontainerstorage" >> /etc/smbcredentials/Totalcontainerstorage.cred'
    bash -c 'echo "password=WPt39LGSSagFVeWbsNJ8HuhTaoPa1aiAZsOR3pBXnrOGjXFWVZj2BqooibIXvqbtjwbn4TLC4j+gJhOAk798pQ==" >> /etc/smbcredentials/Totalcontainerstorage.cred'
fi
chmod 600 /etc/smbcredentials/Totalcontainerstorage.cred

bash -c 'echo "//Totalcontainerstorage.file.core.windows.net/Totalvm /mnt/Totalvm cifs nofail,vers=3.0,credentials=/etc/smbcredentials/Totalcontainerstorage.cred,dir_mode=0777,file_mode=0777,serverino" >> /etc/fstab'
mount -t cifs //Totalcontainerstorage.file.core.windows.net/Totalvm /mnt/Totalvm -o vers=3.0,credentials=/etc/smbcredentials/Totalcontainerstorage.cred,dir_mode=0777,file_mode=0777,serverino

看看 cloud-init User-Data Script。
