描述
将本地标准输入，输出和错误流附加到正在运行的容器
使用
docker attach [OPTIONS] CONTAINER
备选方案
名称，缩写 | 默认 | 描述 |
|---|---|---|
--detach-keys | 重写用于分离容器的密钥序列 | |
--no-stdin | false | 不附加 STDIN |
--sig-proxy | true | 代理所有接收到的信号到过程中 |
父命令
命令 | 描述 |
|---|---|
docker | 泊坞窗 CLI 的基本命令。 |
扩展描述
用于docker attach使用容器的ID或名称将终端的标准输入，输出和错误（或三者的任意组合）附加到正在运行的容器。这允许您查看其正在进行的输出或以交互方式控制它，就好像命令直接在您的终端中运行一样。
注：大
attach命令将显示ENTRYPOINT/CMD过程。这可能看起来像是挂起附加命令，而实际上，进程可能根本没有与终端进行交互。
您可以同时从Docker主机上的不同会话多次附加到同一包含的进程。
要停止容器，请使用CTRL-c。该密钥序列发送SIGKILL到容器。如果--sig-proxy为真（默认），则CTRL-c发送一个SIGINT到容器。您可以从容器中分离并使用CTRL-p CTRL-q键序列保持运行。
注：在容器中作为PID 1运行的进程被Linux专门处理：它忽略任何具有默认操作的信号。因此，进程不会在
SIGINT或SIGTERM除非它被编码来这么做。
禁止在附加到启用tty的容器（即：启动时-t）时重定向docker attach命令的标准输入。
当客户端连接到容器的Stdio时，请使用docker attach，Docker使用~1MB内存缓冲区来最大化应用程序的吞吐量。如果填充了此缓冲区，API连接的速度将开始影响进程输出写入速度。这与其他应用程序类似，如SSH。因此，不建议运行性能关键的应用程序，这些应用程序在前台通过缓慢的客户端连接生成大量输出。相反，用户应该使用docker logs命令来访问日志。
重写分离序列
如果需要，可以为DECHACH配置一个覆盖Docker密钥序列。如果Docker默认序列与用于其他应用程序的密钥序列发生冲突，则此操作非常有用。有两种方法可以定义您自己的分离密钥序列，作为每个容器覆盖或作为整个配置的配置属性。
若要重写单个容器的序列，请使用--detach-keys="<sequence>"带docker attach命令。的格式<sequence>不是一封信阿-Z，或ctrl-与下列任何一项相结合：
a-z（一个小写字母字符）
@（在标志处）
[（左括号）
\\（两个反向斜线）
_（下划线）
^（脱字号；补注号）
这些a，ctrl-a，X，或ctrl-\\的值是有效的密钥序列的所有实施例。要为所有容器配置不同的配置默认密钥序列，请参阅配置文件部分。
示例

获取容器命令的退出代码
在第二个示例中，您可以看到bash进程返回的退出代码也被docker attach命令返回给其调用者：
$ docker run --name test -d -it debian 275c44472aebd77c926d4527885bb09f2f6db21d878c75f0a1c212c03d3bcfab $ docker attach test root@f38c87f2a42d:/# exit 13 exit $ echo $? 13 $ docker ps -a | grep test 275c44472aeb debian:7 "/bin/bash" 26 seconds ago Exited (13) 17 seconds ago test
