The web interface for on-premise Image Builder!
Image Builder generates custom images suitable for deploying systems or uploading to the cloud. It integrates into Cockpit as a frontend for osbuild.
Cockpit Composer can be installed on RHEL and Fedora systems using:
$ dnf install cockpit-composer
Make sure to install/enable Cockpit with:
$ systemctl enable --now cockpit.socket
First download the code from Github:
$ git clone https://github.com/osbuild/cockpit-composer.git
$ cd cockpit-composer/
It's easy to set up your local machine to develop on Cockpit Composer.
On Fedora or Red Hat Enterprise Linux:
- First install Cockpit on your local machine as described in: https://cockpit-project.org/running.html.
- Next install and start osbuild-composer:
$ dnf install osbuild-composer cockpit
$ systemctl start osbuild-composer
- Cockpit Composer uses Node.js during development. Node.js is not used at runtime. To make changes on Cockpit you'll want to install Node.js, NPM.
$ dnf install nodejs npm
- In order to build an rpm,
rpm-buildis required
$ dnf install rpm-build
- To build Cockpit Composer, run:
$ make build
This will create a public directory which can be sym-linked into Cockpit as a plugin:
$ mkdir -p ~/.local/share/cockpit
$ ln -s $(pwd)/public ~/.local/share/cockpit/composer
Now you can log into Cockpit Composer on your local machine at the following address. Use the same user and password that you used to log into your local user account.
https://localhost:9090/composer
Cockpit Composer can also be built in watch mode so that it will rebuild on code changes without having to manually rerun make build. This can be done using:
npm ci
npm run watch
We use eslint and prettier to enforce code style. To run the linters, run:
$ npm run lint
$ npm run prettier
Any auto fixable errors can be corrected with:
$ npm run format
$ make rpm
Run test without visually seeing what the browser is doing:
$ make check
To learn more about testing see our testing docs.
To keep Cockpit Composer working with Cockpit API all code should follow the following rules.
- All urls in the html and javascript need to use relative paths.
- All requests to the API should be made using
utils.apiFetch. Any non APIfetchrequests must usecredentials: 'same-origin'so that cookies are included with those ajax requests. - Use hashes for navigation within the SPA so that cockpit can keep the top level location display up to date.
It is important to keep the NPM modules up to date, to keep up with security updates and bug fixes. This is done automatically by Dependabot. which is run daily.
Similarly, translations are refreshed automatically by Weblate.
