The best way to install, upgrade, or update your REMnux system is usually to use the REMnux installer. However, sometimes you might want to invoke the underlying Salt state files directly, perhaps when experimenting with REMnux or when getting around some deficiency of the REMnux installer.
The Salt state files for the REMnux distro are grouped into "bundles," so it's easier to trigger the installation or upgrade without directly referring to every individual tool's SaltStack state file:
​addon.sls installs the state files for adding REMnux to an existing system without changing its look and feel. This corresponds to the --mode=addon parameter to the REMnux installer.
​dedicated.sls installs the state files for setting up a dedicated REMnux system in a local lab. This applies the same state files as addon.sls, but also invokes the "theme" state file to adjust the system's configuration for the full REMnux experience. This corresponds to the --mode=dedicated parameter to the REMnux installer, and is the default if --mode isn't specified.
​cloud.sls installs the state files for setting up a dedicated REMnux system in a cloud environment. This applies the same state files as dedicated.sls, except it doesn't disable the SSH daemon, which many people use for remote access. This corresponds to the --mode=cloud parameter to the REMnux installer
If you decide to interact with REMnux' Salt state files without the REMnux installer, first make sure a recent version of SaltStack is installed by executing the following commands, assuming you're using Ubuntu 20.04 (Focal) as the base OS:
sudo -swget -O - https://repo.saltproject.io/py3/ubuntu/20.04/amd64/latest/salt-archive-keyring.gpg | apt-key add -echo "deb [arch=amd64] https://repo.saltproject.io/py3/ubuntu/20.04/amd64/latest focal main" | tee /etc/apt/sources.list.d/saltstack.listapt update -yapt install -y salt-minion gitsystemctl disable salt-minionsystemctl stop salt-minion
You can retrieve REMnux' Salt state files, by downloading the desired state file archive from the "releases" area of the REMnux/salt-states repository or clone the repo like this:
sudo git clone https://github.com/REMnux/salt-states.git /srv/salt
You can invoke SaltStack's salt-call utility to install the desired state file grouping. For example, for "dedicated" you'd use the command:
sudo salt-call -l debug --local state.sls remnux.dedicated
The parameter -l debug to the salt-call command provides verbose debug-level output of the operation. You can skip this parameter if you don't want that level of detail.
By the way, if the name of your current user isn't remnux, you'll need to specify the following parameter to the salt-call command:
pillar='{"remnux_user": "YOUR_USERNAME"}'
Replace YOUR_USERNAME with your username. This is equivalent to the --user=YOUR_USERNAME optional parameter to the REMnux installer. The REMnux installer automatically invokes salt-call by specifying the name of the currently-logged in user, but you'll need to specify this yourself if running salt-call directly.
