Powershell 不排除从 azure 存储库中删除图像的正确值

Question

我有如下的 powershell 脚本，但它无法按预期工作，尝试检索图像并从 acr 中删除未运行的图像。

我能够提取图像，但无法按照我的要求删除它们

它应该从 $tagsToDelete 中的 $tagsToExclude 中排除标签

$alltags = foreach ($env in $environment) {
    # Get the list of images from k8s cluster
    $tags = az aks command invoke --resource-group test-$env --name test-$env --command "kubectl get pods --all-namespaces -o jsonpath='{.items[*].spec.containers[*].image}' | tr -s '[[:space:]]' '\n' | sort | uniq -c"
    # Skip the first line comments from PowerShell
    $deletefirstline = $tags | Select-Object -Skip 1
    # Remove the count of the images
    $removecount = $deletefirstline -replace '^\S*\s+'
    # Filter the image tags with "/i;" in the name and extract the tags
    $removecount | Where-Object { $_ -like "*/ip-*" } | ForEach-Object {
        # Extract the image name and version
        $nameVersion = $_ -split '[:/]'
        # Output the image name and version
        "$($nameVersion[2]), $($nameVersion[3])"
    }
}

$groupedData = $alltags | ForEach-Object {
    $parts = $_ -split ', '
    [PSCustomObject]@{ Key = $parts[0]; Value = $parts[1] }
} | Group-Object -Property Key

# Store the output in a variable
$sortedtags = $groupedData | ForEach-Object {
    $key = $_.Name
    $values = $_.Group | ForEach-Object { $_.Value }
    "$key = " + ($values -join "`n")
}

# Extract only the values for ip-id
$ipIdOutput = $sortedtags | Where-Object { $_ -like "ip-id*" } | ForEach-Object {
    $_ -replace "ip-id = ", ""
}

# Extract only the values for ip-data
$ipDataOutput = $sortedtags | Where-Object { $_ -like "ip-data*" } | ForEach-Object {
    $_ -replace "ip-data = ", ""
}

# Extract only the values for ip-hardwave
$ipHardwaveOutput = $sortedtags | Where-Object { $_ -like "ip-hardwave*" } | ForEach-Object {
    $_ -replace "ip-hardwave = ", ""
}

# Extract only the values for ip-tube
$ipTubeOutput = $sortedtags | Where-Object { $_ -like "ip-tube*" } | ForEach-Object {
    $_ -replace "ip-tube = ", ""
}

# Print the ip-id values
$ipIdOutput = $ipIdOutput | ForEach-Object { "latest`n" + ($_ -replace '","', "`n" -replace '"', "") }
$ipDataOutput = $ipDataOutput | ForEach-Object { "latest`n" + ($_ -replace '","', "`n" -replace '"', "") }
$ipHardwaveOutput = $ipHardwaveOutput | ForEach-Object { "latest`n" + ($_ -replace '","', "`n" -replace '"', "") }
$ipTubeOutput = $ipTubeOutput | ForEach-Object { "latest`n" + ($_ -replace '","', "`n" -replace '"', "") }


$registryName = "testcontainers001"
$repositoryName = "org/ip-hardwave"
$tagsToExclude = $ipHardwaveOutput


# List the tags in the repository
$tagslist = az acr repository show-tags --name $registryName --repository $repositoryName --output table


$ipHardwaveOutput.GetType()
$tagsToExclude.GetType()

# Convert $tagslist to an array of strings
$tagsArray = $tagslist -split "`n"

$ipHardwaveOutput.GetType()
$tagsToExclude.GetType()

# Ensure both $tagsArray and $tagsToExclude are trimmed and formatted correctly
$tagsArray = $tagsArray | ForEach-Object { $_.Trim() }
$tagsToExclude = $tagsToExclude | ForEach-Object { $_.Trim() }

# Debugging output to check the contents of $tagsArray and $tagsToExclude
Write-Output "Tags Array:"
Write-Output $tagsArray
Write-Output "Tags to Exclude:"
Write-Output $tagsToExclude

# Filter tags to exclude the specified ones
$tagsToDelete = $tagsArray | Where-Object { $tagsToExclude -notcontains $_ }

# Debugging output to check the contents of $tagsToDelete
Write-Output "Tags to Delete:"
Write-Output $tagsToDelete

# Delete the remaining tags
foreach ($tag in $tagsToDelete) {
    $imageToDelete = "$($repositoryName):$($tag)"
    Write-Output $imageToDelete
    #az acr repository delete --name $registryName --image $imageToDelete --yes --dry-run
}

输出如下

不是用文字换行符替换项目分隔符，而是将输入数据拆分到数组中。

例如更改：

$ipIdOutput = $sortedtags | Where-Object { $_ -like "ip-id*" } | ForEach-Object {
    $_ -replace "ip-id = ", ""
}

至：

$ipIdOutput = @($sortedtags | Where-Object { $_ -like "ip-id*" } | ForEach-Object {
    # remove key and split on comma
    $values = $_ -replace "ip-id = ", "" -split ','
    # trim leading/trailing whitespace, then remove leading/trailing quotes from each value
    $values |ForEach-Object {$_.Trim() -replace '^"(.*)"$','$1'}
})

然后替换以下内容：

$ipIdOutput = $ipIdOutput | ForEach-Object { "latest`n" + ($_ -replace '","', "`n" -replace '"', "") }

与：

# insert "latest" tag on top
$ipIdOutput = @('latest';$ipIdOutput)

重复

$ipDataOutput

、

$ipHardwaveOutput

和

$ipTubeOutput

，即可完成。

$tagsToExclude

从

$ipHardwaveOutput

获取其值，因此通过将其转换为包含单个值作为单独字符串的适当数组，您还可以顺便解决过滤问题。
