建站网站软件8怎么在自己的网站加关键词

1. 看了很多资料，说做互联的一个原因是容器内ip不固定，关掉重启后如果有别的容器启动，之前的ip会被占用，所以做互联创建一个网络，让几个容器处于同一个网络，就可以互联还不受关闭再启动ip会改变的影响，但是其实我拿我做的mysql测试，不管是代码里还是sql连接工具，使用容器内ip根本连接不到，只有使用我本机的ip连接才能连接上，所以实际容器内部ip变化对我的使用并没有影响，但是我特别在网上查了很多，他们好像用本地ip都连接不上，只能用容器内的ip，这个我就不直到为什么了，不过我只是为了学习如何创建网络，以及将新建的容器和既存的容器连接到一个网络即可，现在不懂的地方可以在以后有机会的时候就能知道为什么了，忽略次要的，重点先学会用。
2. 先创建一个网络

   docker network create -d bridge sixdog

3. 查看创建的网络

sixdog@sixiaodong dockerfile % docker network ls
NETWORK ID     NAME      DRIVER    SCOPE
5451e1cd08f8   bridge    bridge    local
d8b19cbdca68   host      host      local
f46cec15b991   none      null      local
1dadf784140f   sixdog    bridge    local

4. 我现在有一个既存的容器mysql-dev，准备把它连接到sixdog网络里

4.1 查看mysql-dev容器

sixdog@sixiaodong dockerfile % docker ps -a
CONTAINER ID   IMAGE                       COMMAND                   CREATED         STATUS                      PORTS                               NAMES
465ae184cd56   mysql:latest                "docker-entrypoint.s…"   23 months ago   Up 24 hours                 33060/tcp, 0.0.0.0:3307->3306/tcp   mysql-dev

4.2 查看mysql-dev部分网络信息

sixdog@sixiaodong dockerfile % docker inspect mysql-dev
其他部分省略

4.3 尝试连接

sixdog@sixiaodong dockerfile % docker network connect sixdog mysql-dev

4.4 查看网络信息

sixdog@sixiaodong dockerfile % docker inspect mysql-dev  
其他部分省略

4.5 我用dbeaver使用172.18.0.2连接了下，连接不上mysql-dev，用我本机的ip可以

5. 新建一个jar的运行环境，配置启动时的外部配置文件里的mysql连接ip改为172.18.0.2，并把这个新创建的容器加到sixdog网络里
   5.1 新建一个jar的运行环

#db访问配置
spring.datasource.url=jdbc:mysql://172.18.0.2:3307/test
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driverClassName =com.mysql.cj.jdbc.Driverserver.port=8082

sixdog@sixiaodong dockerfile % docker run --name appsixdog --network sixdog -p 8082:8082 -d app:v1
74c9a0faaaff167802fd6532278e8e10fe0a1d3cb993c275fe32e064e130fb2d

5.2 查看容器

sixdog@sixiaodong dockerfile % docker ps -a
CONTAINER ID   IMAGE                       COMMAND                   CREATED         STATUS                      PORTS                               NAMES

5.3 查看网络配置

sixdog@sixiaodong dockerfile % docker inspect appsixdog
部分省略
"Networks": {"sixdog": {"IPAMConfig": null,"Links": null,"Aliases": ["74c9a0faaaff"],"NetworkID": "1dadf784140fe418f4bd421b63ecd06ed46a1ebf41d386fba725e454349acb86","EndpointID": "9c64f3dc6bbe49a7ffbfd699b946e55b9ff8d006591d38c2e0fe4fe86602f565","Gateway": "172.18.0.1","IPAddress": "172.18.0.3","IPPrefixLen": 16,"IPv6Gateway": "","GlobalIPv6Address": "","GlobalIPv6PrefixLen": 0,"MacAddress": "02:42:ac:12:00:03","DriverOpts": null}}

5.4 访问页面
…很遗憾，可能是外部配置的文件没有生效所以8082的画面访问失败，我删掉了使用8081再来一遍
5.5.想起来了，需要把配置文件拷贝到容器内

sixdog@sixiaodong dockerfile % docker cp ./application.properties 00581903345c:/home/application.propertiesSuccessfully copied 2.56kB to 00581903345c:/home/application.properties

5.6 进容器内查看确认内容

docker exec -i -t appsixdog /bin/bash

5.7.重启容器

sixdog@sixiaodong dockerfile % docker restart appsixdog
appsixdog

5.8 再次确认画面,报错了，调查后发现其实在容器内品mysql的ip是可以的拼通的，最后意识到，在eclipse里配置的端口是创建容器时映射到外边的3307，而容器内是3306，修改后重启容器，画面可以打开，证明联网后容器可以互相访问，但是要注意端口等信息以容器内为准，而不是创建容器时外边的端口
