將導入的 oracle db dmp 保存在 docker 圖像中

Question

我正在使用 docker 映像通過 docker-compose 文件啟動和運行 Oracle 數據庫。 我還創建了我的應用程序的 dmp 文件，並能夠使用docker exec -it命令將其導入 docker 上的 oracle 服務器。

However every time I restart the docker container, the data is lost and I need to do the entire process of importing the dmp file again by doing a bash on the Oracle server in the docker container.

有什么方法可以將該數據保存到 docker 容器上運行的 Oracle 數據庫服務器？ 我已經嘗試過 docker 提交，但是沒有用。

我需要使用volume位嗎？

Answer 1

你是對的，因為需要卷。 這是在我的設置中工作的完整示例。

我的卷映射是： -v /Users/klrice/workspace/dockerdb/data:/opt/oracle/oradata

然后 oracle 目錄： DIRECTORY docker_vol AS '/opt/oracle/oradata';

expdp cmd 來自主機： docker exec -it db_193 expdp klrice/klrice@xe tables=t1 directory=docker_vol dumpfile=klrice.dmp logfile=klrice_exp.log

結果文件位於主機映射位置： /Users/klrice/workspace/dockerdb/data

docker run --name db_193 --cap-add=SYS_PTRACE --security-opt seccomp=unconfined \
-p 1521:1521  \
-p 8000:8000  \
-e ORACLE_SID=orcl \
-e ORACLE_PDB=xe \
-e ORACLE_PWD=oracle \
-e ORACLE_CHARACTERSET=UTF8 \
-v /Users/klrice/workspace/dockerdb/data:/opt/oracle/oradata \
oracle/database:19.3.0-ee
