Usable Configuration Management

Nico Schottelius <nico-cdist--@--schottelius.org>

1.1. SYNOPSIS

cdist [-h] [-d] [-v] [-V] {banner,config,shell} ...

cdist banner [-h] [-d] [-v]

cdist config [-h] [-d] [-V] [-c CONF_DIR] [-f HOSTFILE] [-i MANIFEST] [-p] [-s] [host [host ...]]

cdist shell [-h] [-d] [-v] [-s SHELL]

1.2. DESCRIPTION

cdist is the frontend executable to the cdist configuration management. cdist supports different subcommands as explained below.

1.3. GENERAL

All commands accept the following options:

-d, --debug

Set log level to debug

-h, --help

Show the help screen

-v, --verbose

Set log level to info, be more verbose

-V, --version

Show version and exit

1.5. CONFIG

Configure one or more hosts

-h, --help

Show the help screen

-c CONF_DIR, --conf-dir CONF_DIR

Add a configuration directory. Can be specified multiple times. If configuration directories contain conflicting types, explorers or manifests, then the last one found is used. Additionally this can also be configured by setting the CDIST_PATH environment variable to a colon delimited list of config directories. Directories given with the –conf-dir argument have higher precedence over those set through the environment variable.

-f HOSTFILE, --file HOSTFILE

Read additional hosts to operate on from specified file or from stdin if ‘-‘ (each host on separate line). If no host or host file is specified then, by default, read hosts from stdin.

-i MANIFEST, --initial-manifest MANIFEST

Path to a cdist manifest or - to read from stdin

-p, --parallel

Operate on multiple hosts in parallel

-s, --sequential

Operate on multiple hosts sequentially

--remote-copy REMOTE_COPY

Command to use for remote copy (should behave like scp)

--remote-exec REMOTE_EXEC

Command to use for remote execution (should behave like ssh)

1.6. SHELL

This command allows you to spawn a shell that enables access to the types as commands. It can be thought as an “interactive manifest” environment. See below for example usage. Its primary use is for debugging type parameters.

-s/--shell

Select shell to use, defaults to current shell

1.7. EXAMPLES

# Configure ikq05.ethz.ch with debug enabled
% cdist config -d ikq05.ethz.ch

# Configure hosts in parallel and use a different configuration directory
% cdist config -c ~/p/cdist-nutzung \
    -p ikq02.ethz.ch ikq03.ethz.ch ikq04.ethz.ch

# Use custom remote exec / copy commands
% cdist config --remote-exec /path/to/my/remote/exec \
    --remote-copy /path/to/my/remote/copy \
    -p ikq02.ethz.ch ikq03.ethz.ch ikq04.ethz.ch

# Configure hosts read from file loadbalancers
% cdist config -f loadbalancers

# Display banner
cdist banner

# Show help
% cdist --help

# Show Version
% cdist --version

# Enter a shell that has access to emulated types
% cdist shell
% __git
usage: __git --source SOURCE [--state STATE] [--branch BRANCH]
             [--group GROUP] [--owner OWNER] [--mode MODE] object_id

1.8. ENVIRONMENT

TMPDIR, TEMP, TMP
Setup the base directory for the temporary directory. See http://docs.python.org/py3k/library/tempfile.html for more information. This is rather useful, if the standard directory used does not allow executables.
CDIST_LOCAL_SHELL
Selects shell for local script execution, defaults to /bin/sh
CDIST_REMOTE_SHELL
Selects shell for remote scirpt execution, defaults to /bin/sh
CDIST_REMOTE_EXEC
Use this command for remote execution (should behave like ssh)
CDIST_REMOTE_COPY
Use this command for remote copy (should behave like scp)

1.9. EXIT STATUS

The following exit values shall be returned:

0
Successful completion
1
One or more host configurations failed
