How to run

Usecase 1

Run commands from local file

1. Create config file - config.toml

Example:

# Credentials
username = "root"
password = "password"

# SSH private and public keys
ssh_private_key = "/home/user/.ssh/id_rsa"
ssh_public_key = "/home/user/.ssh/id_rsa.pub"

# SSH port
ssh_port = "22"

# Connection method: "key" or "password"
connection_method = "key"

# Remote hosts
hosts = [
	"1.1.1.1",
	"2.2.2.2",
	"3.3.3.3"
]

# File with commands for "cmd-runner start" command
commands_file = "commands.txt"

# > Full < source and destination path to file for "cmd-runner copy" command 
source_path = "/opt/scripts/script.sh"
destination_path = "/tmp/script.sh"

2. Create file with commands that you want to run on remote hosts - commands.txt

Example:

apt-get update
apt-get upgrade -y

3. Start program cmd-runner start

If you want files with stdout per host then start cmd-runner with key:

cmd-runner start --file

cmd-runner will create files hostname-output.txt

Usecase 2

Copy local file to remote hosts

1. The same as Usecase 1

2. Start program cmd-runner copy

Usecase 3

Combine Usecase 1 and Usecase 2

You can copy bash script to remote hosts with cmd-runner copy and run this script with cmd-runner start
