1 启动容器报错
报错内容如下：
root@asus:~# docker create -ti --name python centos:latest python
root@asus:~# docker start -ai python
Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"python\": executable file not found in $PATH": unknown
1.
2.
3.
原因：该容器所引用的镜像是centos:latest，其中没有python程序。
解决方法：网上拉取一个包含python的镜像，再执行上面的命令：
docker pull python
docker create -ti --name python python python
docker start -ai python

2 执行docker-compose up -d报错1
报错内容如下：
kibana | FATAL Error: [server.host]: string.base
1.
原因：docker-compose.yml中该配置 SERVER_HOST: 0 出错。
kibana:
environment:
SERVER_NAME: kibana
SERVER_HOST: 0
1.
2.

解决方法：将 SERVER_HOST: 0 改为 SERVER_HOST: 0.0.0.0
3 执行docker-compose up -d报错2
报错内容如下：
kibana | {"type":"log","@timestamp":"2020-02-04T04:28:36Z","tags":["warning","elasticsearch","admin"],"pid":9,"message":"Unable to revive connection: http://elasticsearch:9200/"}
1.
原因：docker中的es的主机名不是默认的elasticsearch，而是es01，需要在docker-compose.yml中手动配置kibana中关联的es主机名。
解决方法：
vim docker-compose.yml
# 在kibana配置中，添加以下内容
kibana:
environment:
ELASTICSEARCH_HOSTS: http://es01:9200

root@asus:~# curl -u root lenovo:8000/v2/_catalog
Enter host password for user 'root':
{"repositories":["centos-latest"]}

8 容器中无法使用ping，vim，ifconfig等命令，且安装出错
问题：执行apt-get install vim报错如下：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package vim
1.
2.
3.
4.
解决方法：执行apt-get update ，然后可以正常安装vim等常用命令。
这个命令的作用是：同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。
另：
安装ping命令： apt-get install -y iputils-ping(ubuntu) 或 yum -y install iputils-ping(centos)
安装ifconfig命令：apt-get install net-tools(ubuntu) 或 yum -y install net-tools(centos)
安装VIM命令：apt-get install vim(ubuntu) 或 yum -y install vim(centos)
安装TELNET命令：apt-get install telnet(ubuntu) 或 yum -y install telnet(centos)
