通过ssh和docker“in tmux”同时连接到多个主机。
intmux的Python项目详细描述
简介
在tmux中连接到多个ssh/docker主机。
intmux是连接到多个ssh/docker主机的命令行应用程序 在tmux会话中。支持连接到ssh主机、本地docker和 码头工人作曲。
对于每个匹配的主机，intmux将为每个
窗口）并设置tmux同步窗格选项（pass--tmux no sync to turn
关闭），然后运行shell（可通过--command、--script或
其他特定于连接方法的开关）。
您可以在tmux会话内部（在其中创建新会话）或外部进行intmux。
ssh
下面的命令创建一个新的tmux会话，其中一个窗口有两个窗格 （一个ssh到host1，另一个ssh到user@host2）：
intmux ssh host1 user@host2
# Connect to hosts listed in inputfile.txt
intmux -i inputfile.txt ssh
# Connect to hosts, with a separate window for each host
intmux --tmux-panes 1 ssh host1 user@host2
# Connect and tail the syslogs:
intmux --command 'sudo tail -f /var/log/syslog' ssh host1 user@host2
# Run a script (copies local script to remote host, and executes it)
intmux --script ./local_script.sh ssh host1 user@host2
docker
intmux还可用于连接所有正在运行的本地Docker实例：
# Connect to all local containers
intmux docker
# Connect to specific containers
intmux docker a_name f947ff94a995
# Look at logs on hosts:
intmux docker --docker-command 'logs -f' a_name f947ff94a995
Docker容器也可以通过ssh连接：
# Connect to all remote containers on two different hosts
intmux ssh-docker host1 user@host2
# Connect to specific containers
intmux ssh-docker --docker-containers "a_name,f947ff94a995" host1 user@host2
# Look at logs on hosts:
intmux ssh-docker --docker-command 'logs -f' --docker-containers "a_name,f947ff94a995" host1 user@host2
docker组合
Docker当前工作目录中所有正在运行的服务都可以 还可以连接到：
# Connect to all containers
intmux compose
# Connect to specific containers:
intmux compose db web
安装
执行：
pip install intmux

sub-command help
ssh Connect to hosts via SSH
docker Connect to docker containers via 'docker exec'
ssh-docker Connect to docker containers on remote SSH hosts
compose Connect to docker containers associated with current
docker-compose via 'docker exec'
optional arguments:
-h, --help show this help message and exit
--log LOG, -l LOG Log level (default: WARN)
--command COMMAND, -c COMMAND
Command to execute when connecting to a remote host
--input INPUT, -i INPUT

--tmux-no-sync, -S Do not run tmux's set-option synchronize-panes
--tmux-session SESSION, -t SESSION

ssh帮助：
intmux ssh -h
usage: intmux ssh [-h] [--ssh-options SSH_OPTIONS] [hosts [hosts ...]]
Connect to the provided hosts.
positional arguments:
hosts SSH hosts to connect to.
optional arguments:
-h, --help show this help message and exit
--ssh-options SSH_OPTIONS, -so SSH_OPTIONS
Options to pass to SSH connection.
Docker帮助：
intmux docker -h
usage: intmux docker [-h] [--docker-command DOCKER_COMMAND] [--approximate]
[hosts [hosts ...]]
Connect to the provided running containers
positional arguments:
hosts List of docker containers to connect to (default:
connect to all containers)
optional arguments:
-h, --help show this help message and exit
--docker-command DOCKER_COMMAND, -dc DOCKER_COMMAND
Docker command to execute (default: 'exec -it {}
bash'). If '{}' is included in the command, the docker
host is substituted there, the host is appended. NOTE:
may invalidate any --script/--command parameters if a
shell is not provided.
--approximate, -a Include any docker container names that only partially
match hosts.
Docker撰写帮助：
intmux compose -h
usage: intmux compose [-h] [--docker-command DOCKER_COMMAND] [--approximate]
[hosts [hosts ...]]
Connect to containers associated with the docker-compose in the current
directory.
positional arguments:
hosts List of docker containers to connect to (default:
connect to all containers)
optional arguments:
-h, --help show this help message and exit
--docker-command DOCKER_COMMAND, -dc DOCKER_COMMAND
Docker command to execute (default: 'exec -it {}
bash'). If '{}' is included in the command, the docker
host is substituted there, the host is appended.
--approximate, -a Include any docker container names that only partially
match hosts.
ssh docker帮助：
intmux ssh-docker -h
usage: intmux ssh-docker [-h] [--ssh-options SSH_OPTIONS]
[--docker-containers DOCKER_CONTAINERS]
[--docker-command DOCKER_COMMAND] [--approximate]
[hosts [hosts ...]]
Connect to docker containers on provided SSH hosts
positional arguments:
hosts SSH hosts to connect to.
optional arguments:
-h, --help show this help message and exit
--ssh-options SSH_OPTIONS, -so SSH_OPTIONS
Options to pass to SSH connection.
--docker-containers DOCKER_CONTAINERS, -dC DOCKER_CONTAINERS
Comma separated list of docker containers to connect
to (default: connect to all containers)
--docker-command DOCKER_COMMAND, -dc DOCKER_COMMAND
Docker command to execute (default: 'exec -it {}
bash'). If '{}' is included in the command, the docker
host is substituted there, the host is appended. NOTE:
may invalidate any --script/--command parameters if a
shell is not provided.
--approximate, -a Include any docker container names that only partially
match hosts.
注释
--script和--command将通过ssh建立多个连接（一个可以发送
通过tmux的键，但在不捕获
$？，因此shell命令已与&；）串在一起。也许我会修好的
有一天，但同时，为了限制连接的数量，我建议
通过将以下内容添加到
.ssh/config文件：
ControlMaster auto
ControlPersist 60s
ControlPath /tmp/ssh-%h-%p-%r
