# 创建并启动containers

创建并启动`docker-compose.yml`或`docker-compose.yaml`文件中的service
```
docker-compose up   # 不推荐
```

执行结果如下：

**注意：** 打印详细日志，执行`ctrl+c`**退出时容器会停止**，一般用于 **调试**

# 创建网络

由上图可见，通过`docker-compose`创建容器时，也会 **创建网络**

### 查看docker网络：
```
docker network ls
```
执行结果如下：

创建一个新的docker网络，是bridge网络模式

### 查看网络详细信息

```
docker network inspect docker_tomcat_default
```
执行结果如下：
```
[
    {
        "Name": "docker_tomcat_default",
        "Id": "0d5e26732eb3ad42304de4ff115ecf244e5c62d7cc9343d61b5f09db51feaf71",
        "Created": "2020-07-27T10:12:09.684302068+08:00",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.30.0.0/16",
                    "Gateway": "172.30.0.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": true,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": {},
        "Options": {},
        "Labels": {
            "com.docker.compose.network": "default",
            "com.docker.compose.project": "docker_tomcat",
            "com.docker.compose.version": "1.26.2"
        }
    }
]
```
ip网段是`172.30.0.0/16`

### 查看linux系统网络

```
ip a
```
执行结果如下：

[![](https://www.malaoshi.top/upload/pic/docker/QQ20200727-102106.png)](https://www.malaoshi.top/upload/pic/docker/QQ20200727-102106.png)

虚拟网卡 红框 部分`0d5e26732eb3`，与 docker网络`0d5e26732eb3`， 是一致的

### 注意网段

`docker-compose` 创建容器时，也会创建网络，该网络ip网段 与 `默认bridge网络`的ip网段，一般不同
`docker run`创建容器时，使用 `默认bridge网络`

2个容器的网段不一样，无法网络通信

##### 解决方法

创建自定义bridge网络，在 docker-compose.yml文件中指定该网络，然后启动

通过`docker run`创建容器时，也指定该网络，见：
https://www.malaoshi.top/show_1EF5xlsxdwTZ.html

# 后台启动

正常启动，不会打印详细日志

```
docker-compose up -d
```

# 指定文件启动
要执行 `xxx.yml`文件时，按照下面格式指定：

```
docker-compose -f abc.yml up -d
```

# 列出 containers

列出`docker-compose.yml`或`docker-compose.yaml`文件中的 containers
```
docker-compose ps
```

# 停止service

停止`docker-compose.yml`或`docker-compose.yaml`文件中的service
```
docker-compose stop
```

# 停止service并删除

停止`docker-compose.yml`或`docker-compose.yaml`文件中的service，并删除containers, networks, images, and volumes
```
docker-compose down
```

# 启动service

启动`docker-compose.yml`或`docker-compose.yaml`文件中的service
```
docker-compose start
```

# 相当于docker exec

```
docker-compose exec 名字 bash
```
其中 `名字` 是在`docker-compose.yml`定义的名字
