查看`Docker`容器的信息

对于运行在Docker环境的容器，有时我们想查询它们的一些基本信息，例如环境变量、hostname、ip地址等，接下来我们以一个tomcat容器为例，看看有哪些方式来取得这些信息；

创建`tomcat`容器

在docker环境下执行如下命令，即可创建一个名为tomcat001的tomcat容器：

docker run --name tomcat001 -idt tomcat

执行docker ps检查一下，容器创建成功：

root@maven:~# docker ps
CONTAINER ID	IMAGE	COMMAND				CREATED			STATUS			PORTS		NAMES
98d119ed4c73	tomcat	"catalina.sh run"	10 minutes ago	Up 10 minutes	8080/tcp	tomcat001

获取信息常用的方式有如下三种：

进入容器内部获取信息；
执行docker exec命令；
执行docker inspect -f命令（推荐方式）；

第一种：进入容器内部获取信息

执行以下命令可进入容器内部：

docker exec -it tomcat001 /bin/bash

此时已进入容器内部，所以分别执行hostname、ip addr、env这三个命令可以获取相关信息，如下：

root@98d119ed4c73:/usr/local/tomcat# hostname
98d119ed4c73
root@98d119ed4c73:/usr/local/tomcat# ip addr

第二种：执行`docker exec`命令

不用进入容器，直接在docker环境执行docker exec 容器名容器内命令的方式也可以获取相关信息，举例如下：

获取容器的hostname：docker exec tomcat001 hostname
获取容器ip地址：docker exec tomcat001 ip addr
获取容器环境变量：docker exec tomcat001 env

执行结果如下所示:

root@maven:~# docker exec tomcat001 hostname
98d119ed4c73
root@maven:~# docker exec tomcat001 ip addr

第三种：使用`docker inspect`命令

推荐使用docker inspect来获取信息，这个命令会返回一个json字符串，里面以key-value的格式准备了该容器相关的信息，内容十分丰富，可以一次性取得全部内容，也可以返回指定key对应的信息；

我们先来看看所有内容，执行命令docker inspect tomcat001，可以看到如下信息：

root@maven:~# docker inspect tomcat001

可见内容十分丰富；

如果我们只对其中的一些感兴趣，例如hostname、ip地址、环境变量，该如何查看呢？

hostname：在返回值中，hostname的位置如下图红框所示，

由上图可见，hostname位于Config.Hostname这个节点位置，所以执行命令docker inspect -f {{.Config.Hostname}} tomcat001即可获取到hostname，如下所示：

root@maven:~# docker inspect -f {{.Config.Hostname}} tomcat001
98d119ed4c73

ip地址：执行命令docker inspect -f {{.NetworkSettings.IPAddress}} tomcat001即可获取到ip地址：

root@maven:~# docker inspect -f {{.NetworkSettings.IPAddress}} tomcat001
172.17.0.5

环境变量：从完整的inspect信息中可以看到环境变量Config.Env的内容是个json数组，所以除了用docker inspect -f {{.Config.Env}} tomcat001获取所有环境变量信息，还可以用docker inspect -f ‘{{index .Config.Env 1}}’ tomcat001命令获取数组中的某一条记录，如下：

root@maven:~# docker inspect -f '{{index .Config.Env 1}}' tomcat001
LANG=C.UTF-8
root@maven:~# docker inspect -f '{{index .Config.Env 2}}' tomcat001 
JAVA_HOME=/docker-java-home/jre

至此，三种获取容器信息的方式已经全部列出，之所以在本文中推荐第三种，是因为有时我们会在shell脚本中获取容器信息，这时候用这种方式最为简单；

Docker 容器启动查看容器状态 - 四

1、容器两种方式进行启动

一种是基于创建一个容器并启动

docker create 
docker start

另一种使用 run 创建自动启动；
是状态下的停止启动

docker start nginx1

docker stop NAMES     # 停止
docker restart NAMES  # 启动

# service docker start# docker run - 运行(创建)一个容器

docker run -d -p 0.0.0.0:18080:8080 --name nginx1 nginx
-d： 让容器在后台运行
-P： 将容器内部使用的网络端口映射到我们使用的主机上
-p： 指定端口
--name ：设置容器命名
nginx 是容器镜像
docker pull nginx  拉取镜像；

2、docker 进入容器系统；

进入一个 nginx1 容器

docker exec -it nginx1 /bin/bash
-d : 分离模式: 在后台运行
-i : 交互模式 即使没有附加也保持STDIN 打开
-t : 分配一个伪终端
/bin/bash ： 运行命令 bash shell

另一种进入方式：

docker attach centos6.3

3、批量操作容器

docker 启动所有的容器
docker start $(docker ps -a | awk '{ print $1}' | tail -n +2)docker 关闭所有的容器
docker stop $(docker ps -a | awk '{ print $1}' | tail -n +2)docker 删除所有的容器
docker rm $(docker ps -a | awk '{ print $1}' | tail -n +2)docker 删除所有的镜像
docker rmi $(docker images | awk '{print $3}' |tail -n +2)

如何查看docker容器运行状态

如何查看docker容器运行状态？有时候，我们需要进入运行的docker容器，查看容器运行情况，查看 docker 容器的状态信息。

查看容器状态：

docker stats nginx1

查看进程信息：

docker top nginx1

使用 docker inspect 来查看Docker的底层信息。它会返回一个 JSON 文件记录着 Docker 容器的配置和状态信息

docker 容器默认的目录：

/var/lib/docker/containers

目录下 12 位开头的就是容器ID
inspect 内容就是 config.v2.json 文件

cat/var/lib/docker/containers/23defb07e362b81fa9d282382dfb5101e7a269f97b3d167493a5b1e031d15120/config.v2.json

inspect 查看容器的配置信息，包含容器名、环境变量、运行命令、主机配置、网络配置和数据卷配置

docker inspect nginx1 查看容器所有状态；

root@rbtnode1: ~# docker inspect --format='{{.NetworkSettings.IPAddress}}' nginx1
172.16.57.5root@rbtnode1: ~# docker inspect --format '{{.Name}} {{.State.Running}}' nginx1
/nginx1 true
