+
+之前的筆記：[[筆記] 設定 google container registry 轉址到 google artifact registry](/2024/10/29/note-gcr-to-gar/)
+
+本文是紀錄使用 Google Cloud 新指令，使得設定更為便捷。
+
+建議操作的帳號擁有 Project Owner Role。
+
+## 執行指令進行搬遷
+
+```bash
+gcloud artifacts docker upgrade migrate \
+    --projects=PROJECTS
+```
+
+其中 `PROJECTS` 可以是一個 Project ID 或是以逗號分隔的多組 Project ID。例如:
+
+```bash
+gcloud artifacts docker upgrade migrate \
+    --projects=my-project-1,my-project-2,my-project-3
+```
+
+該指令會執行以下步驟：
+- 在 Artifact Registry 中為對應區域中列出的每個 gcr.io 專案建立 gcr.io repositories。
+- 為每個 repositories 建議 IAM Policy，並根據使用者選項套用該 Policy 或忽略。
+- 將所有流量從 gcr.io 重新導向至 Artifact Registry。 Artifact Registry 透過 request-time copying 從 Container Registry 複製缺少的 Image 來暫時提供服務，直到所有容器映像都複製到 Artifact Registry。
+- 將 gcr.io buckets 中儲存的所有 Container Image 複製到 Artifact Registry 上託管的新建立的 gcr.io repositories。
+- 停用 request-time copying。ArtifactRegistry 上託管的 gcr.io repositories 不再依賴 Container Registry。
+
+由於步驟中會複製 gcr.io repositories 中的 Container Image，所以如果有許多 Container Image 就會花上不少時間。可以加上參數 `--recent-images` 或 `--last-uploaded-versions` 來決定再複製的時候選擇的 Container Image：
+- `--recent-images=NUM_DAY`: 只複製近期有 Pull 或 Push 的 Container Image，NUM_DAY 的範圍是 30 ~ 90。
+- `--last-uploaded-versions=N`: 近期上傳的 Container Image，N 的範圍是整數。
+
+要注意 `--recent-images` 與 `--last-uploaded-versions` 不能同時使用。
+
+```bash
+gcloud artifacts docker upgrade migrate \
+    --recent-images=60 \
+    --projects=my-project
+```
+
+或是
+
+```bash
+gcloud artifacts docker upgrade migrate \
+    --last-uploaded-versions=5 \
+    --projects=my-project
+```
+
+這個指令會以多執行緒來複製 Container Registry 的 Container Image，可以透過參數 `--max-threads` 調整，預設值為 `8`。
