# create-fcos-iso-with-ssh-key
Quick and easy way to create a personalized iso file of [Fedora CoreOS](https://docs.fedoraproject.org/en-US/fedora-coreos/getting-started/) that contains your public SSH key.
## Introduction
The bash script _create-fcos-iso-with-ssh-key.sh_ will
1. Download an official iso file into a temporary directory (created with `mktemp -d`)
2. Embed your public SSH key on to the iso
3. Print the filepath of the iso to stdout
## Requirements
__podman__ or __docker__
## Usage
```
$ bash ./create-fcos-iso-with-ssh-key.sh podman x86_64 stable ~/.ssh/id_rsa.pub myuser
```
| argument nr | value |
| -- | -- |
| 1 | _podman_ or _docker_ |
| 2 | architecture (_x86_64_, ...) |
| 3 | _stable_, _testing_ or _next_ |
| 4 | path to your public SSH key |
| 5 | username (choose _core_ if you need sudo permissions) |
## Examples
Download the _stable_ release with the architecture *x86_64* and create the user _core_ and let the public SSH key _~/.ssh/id_rsa.pub_
be able to log in over ssh to that account. The software _podman_ is the tool used to run the containers in the bash script.
```
$ bash ./create-fcos-iso-with-ssh-key.sh podman x86_64 stable ~/.ssh/id_rsa.pub core 2> /dev/null
/tmp/tmp.E6sy3HM3Ls/fedora-coreos-32.20201004.3.0-live.x86_64.iso
```
The same command once again, but this time without `2> /dev/null` so that progress information is shown.
```
$ bash ./create-fcos-iso-with-ssh-key.sh podman x86_64 stable ~/.ssh/id_rsa.pub core

### Create USB stick
After creating the iso file, write it to a USB stick. Some tutorials: [Windows](https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview), [MacOS](https://ubuntu.com/tutorials/create-a-usb-stick-on-macos#1-overview), [Ubuntu](https://ubuntu.com/tutorials/create-a-usb-stick-on-ubuntu#1-overview).
### Boot up the USB stick and log in with SSH
Assuming _core_ is the username chosen before and _192.0.2.10_ is the IP address that Fedora CoreOS got from the DHCP server while booting up, you can log in with
```
$ ssh [email protected]
```
