无法在docker容器外部连接到oracle

Question

我已经为oracle 19c创建了一个映像。我已使用以下命令启动容器。

docker-run-name oracledb-d-p 1527:1521-p 5700:5500-e ORACLE\u PWD=password1-e ORACLE\u CHARACTERSET=AL32UTF8-v/d/docker-code/ORACLE-data-ORACLE/database:19.3.0-ee

创建容器后，我可以登录容器。我能够在容器内连接以下命令。

sqlplus系统/password1@172.17.0.2：1527/ORCLCDB

在容器外部，通过cmd，我无法连接到该oracle实例。

注意：我已经在windows计算机上的端口1521（默认端口）安装了oracle。

listener.ora

LISTENER =
(DESCRIPTION_LIST =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.0.2)(PORT = 1527))
  )
)

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = ORCLCDB)
      (ORACLE_HOME = /opt/oracle/product/19c/dbhome_1)
      (SID_NAME = ORCLCDB)
    )
   )


DEDICATED_THROUGH_BROKER_LISTENER=OFF
DIAG_ADR_ENABLED = off

ORCLCDB=172.17.0.2:1527/ORCLCDB
ORCLPDB1=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.0.2)(PORT = 1527))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ORCLPDB1)
    )
  )

我无法从SQL Developer或CMD连接。当我试图访问docker容器外部时，我能够得到超时错误。

ERROR:
ORA-12170: TNS:Connect timeout occurred

请指导我解决这个问题。

提前谢谢。

确保所有容器网络接口都在侦听数据库流量，因此0.0.0.0。不要硬编码docker网桥网络地址（172..），因为该地址将在容器启动时分配。只需使用容器本地的默认端口1521即可。此端口-1521-是容器的本地端口，不暴露于主机操作系统。您将此端口发布到主机操作系统，在主机操作系统中您可以决定使用哪个端口，因此-p 1522:1521

LISTENER =
(DESCRIPTION_LIST =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
  )
)

现在，您可以通过发出以下命令在主机操作系统上启动容器：

docker run --name oracledb -d -p 1522:1521 -p 5700:5500 -e ORACLE_PWD=password1 -e ORACLE_CHARACTERSET=AL32UTF8 -v /d/docker-code/oracle-data oracle/database:19.3.0-ee

现在应该可以了

sqlplus system/password1@localhost:1522/ORCLCDB

提示现在，您可以从Docker Hub中提取Oracle XE 18c。如果仍然无法使用已构建的映像进行连接，我建议您测试此映像。

docker run -d -p 1522:1521 --rm -e ORACLE_PASSWORD=Welcome_1 -v oracle-volume:/opt/oracle/oradata gvenzl/oracle-xe

docker container ls
