使用docker安装Oracle（根据官网整理）

使用docker安装Oracle docker 登录Oracle仓库的账号。（没有的话，要去Oracle官网注册）

docker login -u 用户名 -p 密码 https://container-registry.oracle.com

拉取镜像并启动容器（请保持足够空间的内存与磁盘大小）

 -e ORACLE_PWD:          The Oracle Database SYS, SYSTEM and PDBADMIN password. (Default: auto-generated)
 -e INIT_SGA_SIZE:       The total memory in MB that should be used for all SGA components (Optional)
 -e INIT_PGA_SIZE:       The target aggregate PGA memory in MB that should be used for all server processes attached to the instance (Optional)
 -e ORACLE_EDITION:      The Oracle Database Edition [enterprise|standard]. (Default: enterprise)
 -e ORACLE_CHARACTERSET: The character set that you want used when creating the database. (Default: AL32UTF8)

                         If omitted, then the database will not be persisted over container recreation.
 -v /opt/oracle/scripts/startup | /docker-entrypoint-initdb.d/startup
                         Optional: A volume with custom scripts to be run after database startup.
                         For further details see the section "Running scripts after setup and on
                         startup" section below.

示例：

docker run -d --name oracle\
-p 1521:1521 -p 5500:5500  \
-e ORACLE_SID=huangwen  \
-e ORACLE_PDB=huangwen  \
-e ORACLE_PWD=huangwen  \
-v /opt/oracle/oradata \
container-registry.oracle.com/database/enterprise:21.3.0

检查一下是否连接成功

docker exec -it dbname sqlplus sys/cdb-user-password@cdb-sid as sysdba
# 示例：
docker exec -it oracle sqlplus sys/huangwen@ORCLCDB as sysdba
