Reducing storage thumbprint caused by fonts loading

Opened this issue · 2 comments

Describe the issue

While tracking for excessive consummed storage on our containers host, we found that for every created container, the overall fonts directory was copied - meaning every time a container is spawn, we consume arround 400 MB on the host.

The thing is we need fonts, otherwise generated reports are not properly rendered (causing margin issues, letter padding issues, etc...)

Digging in sources, I figure that if we use the addFontsFromPath (which is what we do, of course), script is :

  1. creating a Fonts directory inside dedicated container path
  2. copying all listed font into that path

In order to enhance this and reduce storage thumbprint of created container, I see those two possible enhancements :

  • Instead copying fonts, we could simply mount the host font directory using read-only flag
  • Instead copying fonts in dedicated container directory, we could do this in a location used as cache and consumed by all containers
  • Unsure, but if the created directory is non longer used once the font is installed, we even can drop it

    navcontainerhelper/Misc/Add-FontsToNavContainer.ps1

    Line 71 in f157a40

    }

Scripts used to create container and cause the issue

$type = $env:type
$country = $env:country
$version = $env:version

$navCredentials = Get-Credential

$artifact = Get-BcArtifactUrl `
    -type $env:type `
    -country $env:country `
    -version $env:version

New-BcContainer `
    -accept_eula `
    -containerName $containerName `
    -artifactUrl $artifact `
    -Credential $navCredentials `
    -shortcuts None `
    -useSSL `
    -isolation process `
    -updateHosts `
    -multitenant `
    -addFontsFromPath c:\windows\fonts `
    -auth NavUserPassword `
    -useTraefik `
    -PublicDnsName $env:docker_host `
    -Restart no

I assume that the 400Mb consumed for fonts is removed again when deleting the container, right?
I likely won't have time to create optimizations for stuff like this, but there are several things you can do right:

You can try to remove the fonts folder Remove-Item -Path (Join-Path $bcContainerHelperConfig.HostHelperFolder "Extensions/$containerName/Fonts") -Recurse -Force after the container is generated to see whether this indeed is possible?

You could also create a folder, which contains the fonts you actually need and install those instead of just using all fonts on the host (which can be a lot).

If you find that the fonts folder can be removed, and it still works after restarting the container, and it still works for Windows 2016 containers, and it still works for Windows 2019 containers and it still works for Windows 2022 containers (and make sure that this works for all BC versions - I cannot see why not though), then I would accept a PR, which removes the fonts folder after installing the fonts - but small optimizations like this requires a lot of testing...

Hi Freddy,

Yes, i confirm that dropping the container using Remove-BcContainer is releasing this space as it's dropping both the container and shared container directory.

I'll make a few tests and submit a Pull Request when I got something which make sense.

I of course didn't wait exclusively after you in order to address this case. My purpose was much more to track and talk about the case to figure what's the best approach to solve it 🙂
