# xk6-ssh
A k6 extension for using of SSH in testing. Built for [k6](https://github.com/grafana/k6) using [xk6](https://github.com/grafana/xk6).
## Build
To build a `k6` binary with this extension, first ensure you have the prerequisites:
- [Go toolchain](https://go101.org/article/go-toolchain.html)
- Git
Then:
1. Download `xk6`:
```bash
go install github.com/grafana/xk6/cmd/xk6@latest
```
2. Build the binary:
```bash
xk6 build --with github.com/grafana/xk6-ssh@latest
```
This will result in a `k6` binary in the current directory.
## Example
```javascript
import ssh from 'k6/x/ssh';
export default function () {
ssh.connect({
username: `${__ENV.K6_USERNAME}`,
password: `${__ENV.K6_PASSWORD}`,
host: [HOSTNAME],
port: 22
})
console.log(ssh.run('pwd'))
}
```
Result output:
```plain
$ ./k6 run script.js

## Testing Locally
This repo includes a [docker-compose.yml](docker-compose.yml) file that starts an [OpenSSH Server](https://docs.linuxserver.io/images/docker-openssh-server) from [LinuxServer.io](https://www.linuxserver.io/).
The `examples` directory contains scripts that are configured to work with this environment out of the box.
> :warning: Be sure that you've already compiled your custom `k6` binary as described in the [Build](#build) section!
We'll use this environment to run some examples.
1. Start the docker compose environment.
```shell
docker compose up -d
```
Once you see the following, you should be ready.
```shell
[+] Running 2/2
⠿ Network xk6-ssh_default Created
⠿ Container xk6-ssh-openssh-server-1 Started
```
Next, we'll use the `k6` binary we compiled in the [Build section](#build) above.
1. Using our custom `k6` binary, we can execute our [example scripts](examples/).
```shell
./k6 run examples/connect-by-rsa-key.js
```
The RSA example will then connect to the local SSH server using the `example_rsa` private key.
## FAQ
### How to start `sudo` commands?
Basically we don't provide sudo password autofill. We suggest to use `/etc/sudoers` for this purpose. Please checkout this [article](https://www.cyberciti.biz/faq/linux-unix-running-sudo-command-without-a-password/) for more details.
