BSSH (🐝SSH)
Bulk SSH is a CLI for executing remote commands via SSH on multiple servers.
Usage: bssh [options] "<command to execute remotely>"
| Options | Description |
|---|---|
| -V, --version | output the version number |
| -f, --file [filepath] | What file contains the SSH commands to run the command with? |
| -i, --identity [identity_file] | The path to your keypair file |
| -s, --synchronous | Just run everything and let results come back in live. More difficult to read results, but more efficient to run commands. |
| -u, --user [username] | The username you wish to use |
| -h, --help | output usage information |
Example
In certain circumstances you just want to go directly to a specific docker instance (say to get to a shell within it)
Rather than:
ssh -i somekey.key ubuntu@swarmmaster.domain.comsudo docker service lssudo docker service ps k28s53gd52fdexitssh -i another.key ubutu@worker3.domain.comsudo docker exec -it 781nd7s5g2s ash
Use BSSH
bssh -f ./production-server-list -i somecommon.key -u ubuntu "sudo docker ps"ssh -i somecommon.key ubuntu@worker3.domain.comsudo docker exec -it 781nd7s5g2s ash
If you have an SSH config set up it is even simpler as you can cut out the key and user:
bssh -f ./production-server-list "sudo docker ps"ssh -i somecommon.key ubuntu@worker3.domain.comsudo docker exec -it 781nd7s5g2s ash
