# Reading arguments from kernel command line
|
|
|
|
Agama configuration can be altered through the kernel command line. It is possible to load a
|
|
full configuration file or to change some specific values.
|
|
|
|
## Loading a new configuration file
|
|
|
|
It is possible to load a new configuration file specifying a URL through the `agama.config_url`
|
|
option. Here are some examples:
|
|
|
|
* `agama.config_url=http://192.168.122.1/my-agama.yaml`
|
|
* `agama.config_url=usb:///agama.yaml`
|
|
|
|
See [URL handling in the
|
|
installer](https://github.com/yast/yast-installation/blob/master/doc/url.md) to find more details
|
|
about the supported URLs.
|
|
|
|
## Custom Installation URL Configuration
|
|
|
|
You can override the default `installation_url` set in the product files [here](https://github.com/openSUSE/agama/tree/master/products.d) by passing the `agama.install_url` parameter as a boot option in the bootloader.
|
|
This is particularly useful for any pre-production testing in openQA.
|
|
|
|
**Note:** Setting this variable will impact all products.
|
|
|
|
### Example Usage
|
|
|
|
To specify a custom installation URLs, pass following as a parameter to kernel in the bootloader.
|
|
You can specify multiple URLs by separating them with commas.
|
|
|
|
```
|
|
agama.install_url=https://myrepo,https://myrepo2
|
|
```
|
|
|
|
## Changing configuration values
|
|
|
|
Instead of loading a full configuration file, you might be interested in adjusting just a few
|
|
configuration values. You must specify the option name in dotted notation. A typical use-case might
|
|
be to use your own SSL certificates:
|
|
|
|
```
|
|
agama.web.ssl=true agama.web.ssl_cert=http://192.168.122.1/mycert.pem agama.web.ssl_key=http://192.168.122.1/mycert.key
|
|
```
|
|
|
|
Changing complex options (e.g., collections) is not supported yet.
|
|
|
|
## Proxy Setup
|
|
|
|
Agama supports proxy setup using the `proxy=` kernel command line option like
|
|
`proxy=http://192.168.122.1:3128` when the installation requires to use an HTTP, HTTPS or FTP
|
|
source. The supported proxy URL format is: protocol://[user[:password]@]host[:port]
|
|
|
|
When the installation system boots, the agama-proxy-setup service will read the proxy URL to be
|
|
used from the kernel command line options or through the dracut ask prompt configuration file
|
|
writing it to the /etc/sysconfig/proxy. After that the microOS Tools setup-systemd-proxy-env
|
|
systemd service will make the proxy variables from that file available to all the systemd units
|
|
writing a systemd config file with all the variables as Enviroment ones.
