NAME
propellor - property-based host configuration management in haskell
SYNOPSIS
propellor [options]
DESCRIPTION
propellor is a property-based host configuration management program written and configured in haskell.
MODES OF OPERATION
propellor --init
Get started by initializing a ~/.propellor/ repository.
After this, you'll edit ~/.propellor/config.hs to configure propellor.
propellor
Once propellor is configured, running it without any options will take action as needed to satisfy
the configured properties of the local host.
If there's a central git repository, it will first fetch from it, check the gpg signature and
merge, and rebuild propellor, so that any configuration changes will immediately take effect.
If propellor is run by a non-root user without any options, this is the same as running propellor
--spin with the hostname of the local host.
propellor --spin targethost [targethost ...] [--via relayhost]
Causes propellor to automatically install itself on the specified target host, or if it's already
installed there, push any updates. Propellor is then run on the target host, to satisfy its
configured properties.
A signed git commit is made by --spin, so that any changes you have made get propagated to the
target host.
Multiple target hosts can be specified; propellor will run on each of them in sequence.
When run with --via, propellor sshes to the relay host and runs propellor --spin hostname from
there. This can be useful when propellor is installing itself, since most of the data transfer is
done between relay host and target host. Note that propellor uses ssh agent forwarding to make
this work, and the relay host sees any privdata belonging to the target host.
Propellor configuration typically uses the FQDN of hosts. The hostname given to --spin can be a
short name, which is then looked up in the DNS to find the FQDN.
propellor --build
Causes propellor to build itself, checking that your config.hs, etc are valid.
You do not need to run this as a separate step; propellor automatically builds itself when using
things like --spin.
propellor --add-key keyid
Adds a gpg key, which is used to encrypt the privdata.
Multiple gpg keys can be added; the privdata will be encrypted so that all of them can decrypt it.
If the gpg secret key is present, git is configured to sign commits using this key. Propellor
requires signed commits when pulling from a central git repository.
propellor --rm-key keyid
Stops encrypting the privdata to a gpg key.
propellor --list-fields
Lists all privdata fields that are used by your propellor configuration. The first 2 columns are
the field name and context, and are followed by a list of the hosts that use that privdata value.
propellor --set field context
Sets a field of privdata. The content is read in from stdin.
propellor --unset field context
Removes a value from the privdata store.
propellor --unset-unused
Removes all values from the privdata store that are not currently in use.
propellor --dump field context
Outputs the privdata value to stdout.
propellor --edit field context
Opens $EDITOR on the privdata value.
propellor --merge
Combine multiple --spin commits into a single, more useful commit.
When using propellor, you may find yourself repeatedly running propellor --spin until you get
things working the way you like. This results in a lot of git commits being made, with
incremental changes.
To clean that up to a single commit, use propellor --merge. A normal interactive git commit will
then be made, consisting of all changes that have been previously committed by --spin, since the
last time a normal git commit was made.
(This will result in a trapezoid pattern in gitk.)
propellor --check
If propellor is able to run, this simply exits successfully.
propellor hostname
When run with a hostname and no other options, propellor will provision the local host with the
configuration of that hostname. This is useful when the local host doesn't yet have its hostname
set correctly.
FILES
~/.propellor/config.hs This is the default config file used by propellor. ./config.hs If propellor is run in a directory containing a config.hs, it assumes that the current directory is a propellor repository, and uses the configuration from the current directory, rather tnan ~/.propellor/
ENVIRONMENT
Set PROPELLOR_DEBUG=1 to make propellor output each command it runs and other debugging information.
GIT CONFIGURATION
git config propellor.debug 1 will configure propellor to output debugging information.
git config propellor.spin-branch foo will configure propellor to refuse to spin when the foo branch is
not checked out.
git config propellor.forbid-dirty-spin true will configure propellor to refuse to spin when there are
uncommitted changes in the ~/.propellor repository.
git config propellor.buildsystem stack makes propellor use stack for building itself, rather than the
default cabal. This only controls the local build of propellor; Hosts can have properties set to control
how propellor is built on them.
The usual git configuration controls which centralized repository (if any) propellor pushes and pulls
from.
Additionally, the url of a remote named "deploy", if it exists in your ~/.propellor/ repository, is used
as the origin url for the other repositories.
