.Synopsis Flush Caches used in ContainerHelper .Description Extract all files from a Container Image necessary to start a generic container with these files .Parameter cache Specify which cache you want to flush (default is all) - calSourceCache is the C/AL Source Cache - alSourceCache is the AL Source Cache - filesCache is the files extracted from other images - applicationCache are the test applications runtime cache (15.x containers) - bakFolderCache are version specific backup sets - bcartifacts are artifacts downloaded for spinning up containers - images are images built on artifacts using New-BcImage or New-BcContainer .Parameter keepDays When specifying a value in keepDays, the function will try to keep cached information, which has been used during the last keepDays days. Default is 0 - to flush all cache. .Example Flush-ContainerHelperCache -cache calSourceCache #> function Flush-ContainerHelperCache { [CmdletBinding()] Param ( [string] $cache = 'all', [int] $keepDays = 0 ) $caches = $cache.ToLowerInvariant().Split(',') $folders = @() if ($caches.Contains('all') -or $caches.Contains('calSourceCache')) { $folders += @("extensions\original-*-??","extensions\original-*-??-newsyntax") } if ($caches.Contains('all') -or $caches.Contains('filesCache')) { $folders += @("*-??-files") } if ($caches.Contains('all') -or $caches.Contains('bcartifacts')) { $bcartifactsCacheFolder = (Get-ContainerHelperConfig).bcartifactsCacheFolder if (Test-Path $bcartifactsCacheFolder) { if ($keepDays) { $removeBefore = [DateTime]::Now.Subtract([timespan]::FromDays($keepDays)) Get-ChildItem -Path $bcartifactsCacheFolder | ?{ $_.PSIsContainer } | ForEach-Object { $level1 = $_.FullName Get-ChildItem -Path $level1 | ?{ $_.PSIsContainer } | ForEach-Object { $level2 = $_.FullName Get-ChildItem -Path $level2 | ?{ $_.PSIsContainer } | ForEach-Object { $level3 = $_.FullName $lastUsedFileName = Join-Path $level3 "LastUsed" if (Test-Path $lastUsedFileName) { $lastUsedFile = Get-Item $lastUsedFileName if ($lastUsedFile.LastWriteTime -lt $removeBefore) { Write-Host "Removing $level3" Remove-Item $level3 -Recurse -Force } } } if (-not (Get-ChildItem -Path $level2)) { Remove-Item $level2 -Force } } if (-not (Get-ChildItem -Path $level1)) { Remove-Item $level1 -Force } } } else { Get-ChildItem -Path $bcartifactsCacheFolder | ?{ $_.PSIsContainer } | ForEach-Object { Write-Host "Removing Cache $($_.FullName)" [System.IO.Directory]::Delete($_.FullName, $true) } } } } if ($caches.Contains('all') -or $caches.Contains('alSourceCache')) { $folders += @("extensions\original-*-??-al") } if ($caches.Contains('all') -or $caches.Contains('applicationCache')) { $folders += @("extensions\applications-*-??","extensions\sandbox-applications-*-??","extensions\onprem-applications-*-??") } if ($caches.Contains('all') -or $caches.Contains('bakFolderCache')) { $folders += @("sandbox-*-bakfolders","onprem-*-bakfolders") } $folders | ForEach-Object { $folder = Join-Path $hostHelperFolder $_ Get-Item $folder -ErrorAction SilentlyContinue | ?{ $_.PSIsContainer } | ForEach-Object { Write-Host "Removing Cache $($_.FullName)" [System.IO.Directory]::Delete($_.FullName, $true) } } if ($caches.Contains('all') -or $caches.Contains('images')) { $bestGenericImageName = Get-BestGenericImageName $allImages = @(docker images --no-trunc --format "{{.Repository}}:{{.Tag}}|{{.ID}}") $bestGenericImage = $allImages | Where-Object { $_.Split('|')[0] -eq $bestGenericImageName } if ($bestGenericImage) { $bestGenericImageId = $bestGenericImage.Split('|')[1] $bestGenericImageInspect = docker inspect $bestGenericImageID | ConvertFrom-Json } $allImages | ForEach-Object { $imageName = $_.Split('|')[0] $imageID = $_.Split('|')[1] $inspect = docker inspect $imageID | ConvertFrom-Json $artifactUrl = $inspect.config.Env | Where-Object { $_ -like "artifactUrl=*" } if ($artifactUrl) { $artifactUrl = $artifactUrl.Split('?')[0] "artifactUrl=https://bcartifacts.azureedge.net/", "artifactUrl=https://bcinsider.azureedge.net/", "artifactUrl=https://bcprivate.azureedge.net/", "artifactUrl=https://bcpublicpreview.azureedge.net/" | % { if ($artifactUrl -like "$($_)*") { $cacheFolder = Join-Path $bcContainerHelperConfig.bcartifactsCacheFolder $artifactUrl.SubString($_.Length) if (-not (Test-Path $cacheFolder)) { Write-Host "$imageName was built on artifacts which was removed from the cache, removing image" if (-not (DockerDo -command rmi -parameters @("--force") -imageName $imageID -ErrorAction SilentlyContinue)) { Write-Host "WARNING: Unable to remove image" } } } } } elseif ($bestGenericImage) { try { if ($inspect.config.Labels.maintainer -eq "Dynamics SMB" -and $inspect.Config.Labels.tag -ne "" -and $inspect.Config.Labels.osversion -ne $bestGenericImageInspect.Config.Labels.osversion) { Write-Host "$imageName is a generic image for an old version of your OS, removing image" if (-not (DockerDo -command rmi -parameters @("--force") -imageName $imageID -ErrorAction SilentlyContinue)) { Write-Host "WARNING: Unable to remove image" } } } catch {} } } Write-Host "Running Docker image prune" docker image prune -f > $null Write-Host "Completed" } } Export-ModuleMember -Function Flush-ContainerHelperCache |
