특정 조건의 GameServer 삭제

workflow DeleteAllGS
{
    $nsName = "cv-agones-dev"
    $gslist = (kubectl get gs -n $nsName -o json | ConvertFrom-Json).items

    ForEach -Parallel ($gs in $gslist) {
        if ($gs.status.state -eq "Starting") {
            kubectl delete gs $gs.metadata.name -n $nsName
        }
    }
}
DeleteAllGS

 

 

GameServer의 일부 정보 출력

{
    $nsName = "cv-agones-dev"
    $gslist = (kubectl get gs -n $nsName -o json | ConvertFrom-Json).items

    foreach ($gs in $gslist){
        if ($gs.status.state -eq "Allocated"){
