Oracle 23ai Mac M3 Docker Tips

Colima（Container Lima）是一款专为 macOS 设计的轻量级工具，用于在本地快速运行容器化环境（如 Docker 或 containerd）。它基于 Lima（Linux 虚拟机）实现，通过简化的命令行操作，为 macOS 用户提供无缝的容器开发体验，尤其适合替代 Docker Desktop。

Colima (Container Lima) is a lightweight tool designed specifically for macOS to quickly run containerized environments (such as Docker or containerd) locally. Built on Lima (Linux Virtual Machine), it provides macOS users with a seamless containerized development experience through simplified command-line operations, making it an ideal replacement for Docker Desktop.

Docker 是一种开源的容器化平台，用于开发、部署和运行应用程序。它通过将应用程序及其依赖项打包到一个轻量级的容器中，实现了应用程序的快速部署和跨平台运行。

Docker is an open-source containerization platform used for developing, deploying, and running applications. By packaging applications and their dependencies into lightweight containers, it enables rapid deployment and cross-platform operation of applications.

Oracle Database 23ai Free 是 Oracle 官方提供的免费版本，适用于学习、开发和测试。它包含了 Oracle 23ai 的核心功能，但有一些限制（例如，只能使用 2 个 CPU 和 2GB 内存）。可以在个人电脑或虚拟机中安装和使用。

Oracle Database 23ai Free offers the ability to experience Oracle Database, which businesses throughout the world rely on for their mission-critical workloads. The resource limits for Oracle Database Free are up to 2 CPUs for foreground processes, 2 GB of RAM and 12 GB of user data on disk. It is packaged for ease of use and simple download.

Oracle REST Data Services (ORDS) 让您的 Oracle 数据库启用 HTTPS 功能。作为一个中间层 Java 应用，ORDS 提供了数据库管理 REST API、SQL Developer Web、PL/SQL 网关和适用于 REST 的 SODA，并且支持发布 RESTful Web 服务，可与 Oracle 数据库中的数据和存储过程进行交互。

Oracle REST Data Services (ORDS) bridges HTTPS and your Oracle Database. A mid-tier Java application, ORDS provides a Database Management REST API, SQL Developer Web, a PL/SQL Gateway, SODA for REST, and the ability to publish RESTful Web Services for interacting with the data and stored procedures in your Oracle Database.

To get started (using Docker here as an example), simply use the following command, replacing “<your-password>” with the password you want to use for the Oracle Database SYS and SYSTEM users:

docker run --name oracle-free -p 1521:1521 -e ORACLE_PWD=<your-password> container-registry.oracle.com/database/free:latest-lite

For example: ouser@ouser-mac ~ % docker run --name oracle-free -p 1521:1521 -e ORACLE_PWD=OracleIsAwesome container-registry.oracle.com/database/free:latest-lite

docker端口示例说明: 将宿主机的 8080 端口映射到容器的 80 端口
docker run -d -p 8080:80 nginx

docker文件映射通常在运行容器时通过 -v 或 --mount 参数来指定。
例如，如果你想将宿主机上的某个目录映射到容器中，可以使用以下命令：
docker run -v /path/to/host/directory:/path/in/container image_name

内存不够，可能出现上面错误 也可以colima start --edit 编辑默认值如cpu设置为4/内存2g改为6g
If the memory is insufficient, the error mentioned above may occur. You can also use the command colima start --edit to edit the default settings, such as changing the CPU setting from 4 to 6 and the memory from 2G to 6G.

上面稍微花点时间
The above process may take a little time.

加了下面两个出错,时间也很久！  
Adding the following two caused errors, and it also took a long time!
