当前的情况

在已创建的虚拟主机上，Docker主机的状态为非活动。

%docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL   SWARM   DOCKER    ERRORS
default   -        virtualbox   Stopped                 Unknown

在虚拟盒子上启动Docker守护进程

%docker-machine start default
Starting "default"...
(default) Check network to re-create if needed...
(default) Waiting for an IP...
Machine "default" was started.
Waiting for SSH to be available...
Detecting the provisioner...
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

在虚拟箱内启动Docker守护程序并确认其启动情况。

%docker-machine ls                 
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER      ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v19.03.12

连接到虚拟盒子上的Docker守护程序。

%docker-machine env          
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/da-shibata/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(docker-machine env)

通过下面的命令来集中设置上述环境变量以建立连接。

%eval $(docker-machine env)

在虚拟盒上的Docker主机上启动Apache容器。

%docker run --name my-apache-app -p 8080:80 -v $PWD:/usr/local/apache2/htdocs/ httpd:2.4

忘记添加-d选项，它将以FOREGROUND模式运行，导致命令提示符不再返回。

确认Apache是否启动

起動正常。
由于指定了$PWD，当前目录已公开。但实际公开时，请选择主机端的目录。

以下不涉及docker machine的操作。这是在主机操作系统上启动Apache容器的示例。

查看日志的方法

在后台启动Apache

% docker run -d --name apache -p 8080:80 -v $PWD:/usr/local/apache2/htdocs/ httpd:2.4

执行docker logs命令

在执行docker logs之后，指定容器ID或容器名称。

如果使用容器名称进行指定的话

% docker logs apache

如果使用容器ID进行指定

只要指定容器ID的前2位即可。
