# docker ps的结果很乱怎么办

docker ps是我们最常用的docker命令之一。用来查询当前运行中的容器，但是这个命令显示的结果很乱，如下图：

## 1.命令

显示的内容分为6列，但是由于有些列的内容比较长，再加上电脑屏幕宽度有限，导致显示的内容发生了换行，看上去极其的混乱。我们可以通过format参数，来过滤一些不需要查看的列，这样就清晰多了。一般来说，创建时间我不太关心，默认执行的命令也不关心，docker ps查询出来的本来就是运行中的容器，所以容器状态我也不关心，那么我就隐藏掉这两列，命令如下：

```
docker ps -a --format "table {{.ID}}\t{{.Image}}\t{{.Names}}\t{{.Status}}"
```

## 2.命令别名设置

当然每次都敲这么长的命令是很让人头大的，那么我们可以创建一个命令别名

打开用户的命令别名配置文件

```
 vim ~/.bashrc
```

在文件最后追加

```
alias dockerps='docker ps -a --format "table {{.ID}}\t{{.Image}}\t{{.Ports}}\t{{.Names}}\t{{.Status}}\t"'
alias dockerport = 'docker ps -a --format "table {{.Image}}\t{{.Ports}}\t"'
```

重新加载配置，使别名生效

```
 source ~/.bashrc
```

下面就可以用我们显示清晰的dockerps命令啦

## 3.各个占位符汇总

当然，如果你希望显示其他的列，那么请参考如下表格
