如何等待 Firestore 索引部署？

Question

使用firebase deploy时，索引部署阶段会自动完成，但索引可能需要很长时间（10 分钟以上）才能真正准备好使用。

在继续推送依赖于索引的代码之前，如何让我的部署脚本等待索引实际准备就绪？

Answer 1

此gcloud命令将显示正在进行的操作：

$ gcloud firestore operations list --format=json --filter="done:false"
[
  {
    "metadata": {
    "@type": "type.googleapis.com/google.firestore.admin.v1.IndexOperationMetadata",
      "index": "projects/foo/databases/(default)/collectionGroups/bar/indexes/CICAgJiljJcK",
      "progressDocuments": {
        "estimatedWork": "1133"
      },
      "startTime": "2023-01-18T16:05:43.603428Z",
      "state": "INITIALIZING"
    },
    "name": "projects/foo/databases/(default)/operations/S2NKamxpSmdBQ0lDDCoDIGI5ZjRjOWNiYTc0MC05MDlhLWJhYzQtM2M5MC1jMjQwMmI3NCQadGx1YWZlZAcSMXJoLXJleGVkbmktbmltZGERClIS"
  }
]

当没有任何进展时，它将返回[] 。 我们可以编写一个 bash 脚本来等待它：

starttime=$(date +"%s")
nowtime=$(date +"%s")
    
# Run for up to 30 minutes (1800 seconds)
while [[ $(( $nowtime - $starttime )) -le 1800 ]]
do
    response=$(gcloud --project=column-sam firestore operations list --format=json --filter="done:false")
    if [ "$response" == "[]" ]; then
      echo "Finished"
      exit 0
    fi
    
    echo "[$nowtime] Indexes still building, waiting 10 seconds"
    sleep 10
    nowtime=$(date +"%s")
done
    
echo "[$nowtime] Timed out waiting for indexes to build!"
exit 1
