JAVA开发与运维（docker运维常规操作）

使用docker来安装软件步骤。

1、先装好docker环境。

2、通过docker pull 命令拉取你想要安装的软件镜像和版本。

如：以安装Apollo为例

docker pull apolloconfig/apollo-configservice:1.9.1
docker pull apolloconfig/apollo-adminservice:1.9.1
docker pull apolloconfig/apollo-portal:1.9.1

3、通过docker images 命令 查看拉取的镜像

[root@t-xxxx-app1 apollo]# docker images 
REPOSITORY                          TAG       IMAGE ID       CREATED         SIZE
nginx                               latest    904b8cb13b93   3 weeks ago     142MB
openjdk                             8         b273004037cc   7 months ago    526MB
apolloconfig/apollo-portal          1.9.1     b00edd91aba7   18 months ago   157MB
apolloconfig/apollo-adminservice    1.9.1     060bf4ef6ef0   18 months ago   163MB
apolloconfig/apollo-configservice   1.9.1     d4cbf589357b   18 months ago   167MB

4、去启动容器，可以将命令放在shell脚本中

docker run -d 
    --name apollo-portal 
    --net=host 
    -v /tmp/logs:/opt/logs 
    -e SPRING_DATASOURCE_URL=
"jdbc:mysql://数据库地址/ctg_apollo_portal_test?characterEncoding=utf8" 
    -e SPRING_DATASOURCE_USERNAME=数据库账号
    -e SPRING_DATASOURCE_PASSWORD=数据库密码
    -e APOLLO_PORTAL_ENVS=test 
    -e TEST_META=http://服务器ip地址:8080 
    apolloconfig/apollo-portal:1.9.1

5、docker logs --tail 1000 容器名称 去查看启动日志

docker logs --tail  1000 apollo-portal

6、docker ps 查看正在运行的容器

[root@t-xxx-app1 apollo]# docker  ps
CONTAINER ID   IMAGE                                     COMMAND                  CREATED          STATUS             PORTS                                       NAMES

7、删除容器 docker rm 容器ID

docker rm  容器ID

8、删除镜像 docker rmi 镜像ID

docker  rmi  镜像ID
