Question: How do you handle secrets when azure image builder?

Hey Guys,

How do you handle secrets when azure image builder?

Let's say i have customization, that logins to my container register and pulls an image. How can I pass my login details in secure way?

```
az image builder customizer add -n $mytemplate -g $myResourceGroup --type powershell --customizer-name pulldockerimages --defer --exit-codes 0 `
--inline-script `
'docker login myrepo.azurecr.io --username myUser--password myPassword' `
'docker pull myrepo.azurecr.io/imv:onprem-18.4.28601.29139-w1-10.0.17763.2300-ltsc2019' `
```

Now, it's just stored as plain text and could be seen on Image template Json view, and logs


Best Regards,
