Loop over all lines of host ip addresses specified in the hosts.txt
|
||
|
|
file, and execute the the script with the id.rsa given as the input argument.
|
||
|
|
This script will run until done, to kill it use:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
CTRL+z
|
||
|
|
pkill -f loop-wrapper
|
||
|
|
```
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
- This is a helper script that will copy a script you want to run on one or more nodes, and execute it.
|
||
|
|
- The result of running the script will be returned in the `status.log` file.
|
||
|
|
- The script wil continue running until execution on all nodes are succesful.
|
||
|
|
- The result when successful run on a host will be written to the `done.log` file, with the output specified.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Specify the the hosts to execute the script on in the `hosts.txt` file, notation `ip-address,node-name` separated by new lines.
|
||
|
|
|
||
|
|
Example :
|
||
|
|
|
||
|
|
```text
|
||
|
|
10.0.0.1,node1
|
||
|
|
10.0.0.2,node2
|
||
|
|
```
|
||
|
|
|
||
|
|
And start running the script with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
./loop-wrapper <script-to-copy-and-execute> <path-to-id.rsa file>
|
||
|
|
```
|
||
|
|
|
||
|
|
### The script to be executed
|
||
|
|
|
||
|
|
To get the output written to `done.log` from the script that have been copied and ran on the nodes, it should write the desired output to `STDOUT` as it's last thing before calling `exit 0`.
|
||
|
|
|
||
|
|
The same goes for error messages.
|
||

See more details in the `test.sh` file for an example.
