Use Bolt commands to connect directly to the systems where you want to execute commands, run scripts, and upload files.
Run a command on remote nodes
Specify the command you want to run and which nodes to run it on.
When you have credentials on remote systems, you can use Bolt to run commands across those systems.
To run a command on a list of nodes:
bolt command run <COMMAND> --nodes <NODE NAME>,<NODE NAME>,<NODE NAME>
To run a command on WinRM nodes, indicate the WinRM protocol in the nodes string:
bolt command run <COMMAND> --nodes winrm://<WINDOWS.NODE> --user <USERNAME> --password <PASSWORD>
To run a command that contains spaces or shell special characters, wrap the command in single quotation marks:
bolt command run 'echo $HOME' --nodes web5.mydomain.edu,web6.mydomain.edu
bolt command run "netstat -an | grep 'tcp.*LISTEN'" --nodes web5.mydomain.edu,web6.mydomain.edu
To run a cross-platform command:
bolt command run "echo 'hello world'"Note: When connecting to Bolt hosts over WinRM that have not configured SSL for port 5986, passing the
--no-sslswitch is required to connect to the default WinRM port 5985.
Running commands with redirection or pipes
When you run one-line commands that include redirection or pipes, pass
bash or another shell as the command.
Using a shell ensures that the one-liner is
run as a single command and that it works correctly with
run-as. For example,
bolt command run "echo foo > /root/foo" --run-as root, use
command run "bash -c 'echo foo > /root/foo'" --run-as root.
Run a script on remote nodes
Specify the script you want to run and which nodes to run it on.
bolt script run command to run existing scripts that you use or to combine the commands that you regularly run as part of sequence. When you run a script with Bolt, the script is transferred into a temporary directory on the remote system, run on that system, and then deleted.
You can run scripts in any language as long as the appropriate interpreter is installed on the remote system. This includes Bash, PowerShell, or Python.
To run a script, specify the path to the script, and which nodes to run it on:
bolt script run <PATH/TO/SCRIPT> --nodes <NODE NAME>,<NODE NAME>,<NODE NAME>
bolt script run ../myscript.sh --nodes web5.mydomain.edu,web6.mydomain.edu
When executing on WinRM nodes, include the WinRM protocol in the nodes string:
bolt script run <PATH/TO/SCRIPT> --nodes winrm://<NODE NAME> --user <USERNAME> --password <PASSWORD>
To pass arguments to a script, specify them after the command. If an argument contain spaces or special characters, you must quote it:
Argument values are passed literally and are not interpolated by the shell on the remote host. If you run
bolt script run myscript.sh 'echo hello'
bolt script run myscript.sh 'echo $HOME', then the script receives the argument
'echo $HOME', rather than any interpolated value.
Requirements for scripts run on remote *nix systems
#!) line specifying the interpreter. For example, for a script written in Bash, provide the path to the Bash interpreter:
#!/bin/bash echo hello
Requirements for scripts run on remote Windows systems
.pp. To enable other file extensions, add them to your Bolt configuration file, as follows:
winrm: extensions: [.py, .pl]
Upload files or directories to remote nodes
Use Bolt to copy files or directories to remote nodes.
To upload a file or directory to a remote node, run the
bolt file uploadcommand. Specify the local path to the file or directory, the destination location, and the target nodes.
bolt file upload <SOURCE> <DESTINATION> --nodes <NODE NAME>,<NODE NAME>
bolt file upload my_file.txt /tmp/remote_file.txt --nodes web5.mydomain.edu,web6.mydomain.edu
