无法连接到docker容器外部的oracle

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

ERROR:
ORA-12170: TNS:Connect timeout occurred

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计算机上的默认端口1521安装了oracle。

    (CONNECT_DATA =

      (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

提前感谢。

确保所有容器网络接口都在侦听数据库通信，因此

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

小费。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

祝你好运

您是否在Windows网络IP中添加了

172.17.0.2

？我的意思是你能ping

172.17.0.2

？

172.17.0.2

我不能ping这个ip。我没有在Windows网络中添加IP。如何添加它？以管理员身份运行命令提示符程序，然后运行

ipconfig

查看它是否存在。我对Windows中的Docker不太熟悉，但在Linux中它增加了。您的容器端口是1527，因此：-p[host\u port]：[container\u port]->-p 1521:1527。但是既然1521已经被采用了，make是另外一个东西->-p 1522:1527。现在您可以连接：sqlplus系统/password1@localhost:1522/ORCLCDB@BjarteBrandt-我是否需要在docker文件中或在为oracle 19c创建映像时更改某些内容？到目前为止，在创建docker映像时，我已将端口值从1521更改为1527。根据您建议的更改，我仍然无法连接容器外部。在docker容器中，我能够连接这个，

sqlplus系统/password1@localhost：1527/ORCLCDB

但在docker容器外部，我无法连接此，

sqlplus系统/password1@localhost：1522/ORCLCDB

谢谢@Bjarte，这是有效的！！
