拷贝 pg_hba.conf 配置文件至本机

[root@ecs-hce ~]# sudo docker cp postgres:/var/lib/postgresql/data/pg_hba.conf /home

修改 pg_hba.conf 文件,在# IPv4 local connections:后添加以下内容,并保存

pg_hba.conf 文件用于配置客户端对 PostgreSQL 数据库的连接权限,最后一行配置了一条规则,允许来自任意 IP 地址(0.0.0.0/0)的所有用户(all)以 “trust” 方式进行身份验证访问所有的数据库(all)

[root@ecs-hce ~]# vi /home/pg_hba.conf

创建 Docker 网络

创建了一个名为 “oa-net” 的 Docker 网络。该命令返回一个长字符串作为网络标识符

[root@ecs-hce java]# docker network create oa-net
8858411315a892cd61bbe8b31411595dd8b013792fd05ab68806f3ca5572c3a7
[root@ecs-hce java]# docker network connect oa-net postgres
[root@ecs-hce java]# docker network connect oa-net redis-sys

将名为 “postgres” 的容器连接到 “oa-net” 网络中。这将使 “postgres” 容器能够与 “oa-net” 网络中的其他容器进行通信。

将名为 “redis-sys” 的容器连接到 “oa-net” 网络中。这样, “redis-sys” 容器也可以与 “oa-net” 网络中的其他容器进行通信。

通过上面的方式连接之后,即可以通过容器名字作为域名直接访问容器对应的服务,在最开始的版本中,docker 会在 hosts 文件主动写入映射关系,从 Docker 1.11 版本开始,Docker 不再将容器的 DNS 映射关系写入宿主机的 /etc/hosts 文件

修改 jar 包配置文件,使用 vim 打开 jar 包,这里主要修改对应的 PGredis 地址

[root@ecs-hce java]# vim oasys-0.0.1-SNAPSHOT.jar
[root@ecs-hce java]# vim oasys-0.0.1-SNAPSHOT.jar
[root@ecs-hce java]#

输入 /application.properties 搜索该文件,并敲回车键 2 次进入该文件
