如果有任何帮助，我将不胜感激。我整天都在寻找解决问题的方法，但找不到任何有效的方法。我有几个 docker 容器:一个 spring 应用程序、一个 postgres 数据库、keycloak 和一个 postgres 数据库备份。当我使用 Postman 或 curl 通过端点创建新实体时，我还可以通过另一个端点检索它。但是，数据库中没有保存任何内容。当我重新启动 spring 容器时，所有数据都消失了!我只是不明白为什么数据没有保存在数据库中。
这是我的 docker-compose 文件:
services:
sales-service:
container_name: service-container
image: "mab123/sales-service:latest"
environment:
PG_HOST: postgres-container
ports:

我没有在 docker-compose 文件中发现任何可能出错的地方，但如果您有任何想法，请告诉我。
这是我的应用程序开发设置:
spring:
datasource:
url: jdbc:postgresql://${PG_HOST:localhost}:5432/sales
username: postgres
password: postgres
flyway:
datasources:
default:
enabled: true
PG_HOST 是 postgres docker 容器的名称。
如前所述，当我创建一个新实体时，我收到一个 JSON 响应，其中包含 DTO 对象以及实体中分配的 ID。但是，当我访问 Postgres 数据库容器并执行 psql 命令时，结果显示零行。
最佳答案
这是个有趣的话题，我从来没有想过，但从你最初的想法来看，它告诉我如何显示数据库中的内容。谢谢!
由于没有你的 spring boot 源，我无法浏览你的 sales 数据库，但我可以看到 keycloak 数据库。
这是我对来自 postgres docker 的 keycloak 数据库的实验。
我认为您的 sales 数据库未公开或有问题。
数据库名称是 keycloak 用户是 Postgres 中的 keycloak
它将在以后访问数据库时使用。
我敢肯定，这些步骤给出了如何查看您的 sales 数据库的想法。
希望对keycloak和数据库之间的debug有所帮助。

#1 第一步，获取postgres容器ID
docker ps -a
->
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c48f3f8fea9f quay.io/keycloak/keycloak:18.0.2-legacy "/opt/jboss/tools/do…" 54 minutes ago Up 54 minutes 0.0.0.0:8080->8080/tcp, 8443/tcp docker-compose-keycloak-1

#2 第二步，进入postgres容器
(* 注意:我使用的是 Windows git bash，winpty 在 Linux 中不需要)
winpty docker exec -it 254a2038d581 bin/bash
-->
root@254a2038d581:/#
#3 第三步，查看Linux版本
cat /etc/os-release
-->
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
检查我是谁
whoami
-->
root
#4 第 4 步，添加用户 'keycloak` 并添加 sudo 用户
(密码为密码)
adduser keycloak
-->
Adding user `keycloak' ...
Adding new group `keycloak' (1000) ...
Adding new user `keycloak' (1000) with group `keycloak' ...
usermod -aG sudo keycloak
#5 第五步，切换用户keycloak并连接数据库
su keycloak
-->
keycloak@254a2038d581:/$
psql -U keycloak -w
-->
psql (14.5 (Debian 14.5-1.pgdg110+1))
Type "help" for help.
keycloak=#
#6 第六步，获取连接信息
\conninfo
-->
You are connected to database "keycloak" as user "keycloak" via socket in "/var/run/postgresql" at port "5432".
#7 第 7 步，列出表和模式
\dt
