## How to use cdist
|
||||
|
||||
man cdist
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
## How cdist works
|
||||
|
||||
### Exploring your system
|
||||
|
||||
cdist analyses the system to apply the configuration on and
|
||||
selects the right backends. You can use ***cdist-explore*** to
|
||||
the results of the explore functions.
|
||||
|
||||
### Applying the configuration
|
||||
|
||||
cdist looks for the configuration to apply on the local host
|
||||
and applies it using ***cdist-apply***.
|
||||
|
||||
### Managing many hosts
|
||||
|
||||
Whereas ***cdist-apply*** manages one host, ***cdist-deploy***
|
||||
applies the configuration on enabled hosts.
|
||||
|
||||
## How to use cdist?
|
||||
|
||||
0. Create a host specification (/etc/cdist/hosts/**hostname**)
|
||||
0. Add functionalilty to add
|
||||
0. Run ***cdist-apply***
|
||||
|
||||
|
||||
## What do I need [from puppet?]
|
||||
|
||||
### Abstraction of package managers
|
||||
|
||||
I don't want to care about apt, rpm, yum, pacman, etc. I just
|
||||
want to ensure, some package exists or does not exist.
|
||||
|
||||
|
||||
### Common tasks already done
|
||||
|
||||
- [LIBRARY] All the helper types like
|
||||
- file
|
||||
- ssh_keys
|
||||
- package
|
||||
- service
|
||||
- user
|
||||
|
||||
### PORTABILITY
|
||||
- [PORTABILITY] clients for every unix
|
||||
- mostly ruby + facter in puppet
|
||||
|
||||
### Other
|
||||
- Modules: Nice to put stuff together
|
||||
- and reuse
|
||||
- [CONDITIONS] facter is cool
|
||||
- the DSL
|
||||
- with many bugs
|
||||
- templates
|
||||
- Client/Server approach is nice to have
|
||||
- Clients only get the part of the documentation, that's
|
||||
relevant to them
|
||||
- detect impossible/unsafe things:
|
||||
- creating a file twice
|
||||
- installing and removing a package
|
||||
- and report location of occurence
|
||||
- parse afterwards?
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
what is puppet? [FOR ME]
|
||||
|
||||
A configuration deployment assistant,
|
||||
a DSL that allows you define the objectives.
|
||||
A webserver with fileserver capabilities.
|
||||
A client based scheduled polling infrastructure.
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
What do I miss from puppet?
|
||||
|
||||
- speed
|
||||
- elegance
|
||||
- clean design
|
||||
- documentation
|
||||
- the "no surprise" factor
|
||||
- easy to use "data memory" (i.e. external ressources)
|
||||
- easy integration into installation process
|
||||
- copy identity to master
|
||||
- multi master setups
|
||||
- development configurations / tests
|
||||
- editing of configuration files
|
||||
- similar to cfengine
|
||||
- replace bug squasher with bug avoidance
|
||||
- qmail did not need one either
|
||||
- push infrastructure
|
||||
- real / meaningful error messages
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
Simple stuff done by Unix[notm]
|
||||
|
||||
- DSL: Shell!
|
||||
- gives if, else and EVEN elsif for free!
|
||||
- and case
|
||||
- and and and
|
||||
- and there's no os (solaris doesn't count) without a usable /bin/sh
|
||||
- cdist defines what you can use
|
||||
- you _can_ use os specific stuff
|
||||
- but it's ugly and you shoot into your own foot
|
||||
- "manifests" (use the same name here?) will be run/sourced
|
||||
- inheritance possible via sourcing
|
||||
- cdist-lib always preloaded
|
||||
- library == functions?
|
||||
- version control via git
|
||||
- file distribution via ssh
|
||||
- authentication via ssh
|
||||
- dumb clients, similar to manifest compile in puppet
|
||||
- clients just execute commands
|
||||
- dependencies via make?
|
||||
- how to ensure sigletons / conflicting definitions?
|
||||
file { "/a":
|
||||
ensure => present,
|
||||
file { "/a":
|
||||
ensure => absent,
|
||||
- matching on explored items, not only on host name?
|
||||
- match function in host? [optional]
|
||||
- file source:
|
||||
- relative to specification
|
||||
- or absolute
|
||||
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
Implementation
|
||||
|
||||
"cdist-server"
|
||||
-> called by cron?
|
||||
-> no need to reimplement scheduling
|
||||
"cdist-explore" (facter replacement)
|
||||
-> running on the client
|
||||
--------------------------------------------------------------------------------
|
||||
Requirements:
|
||||
It MUST be incredible easy/dumb to add new types.
|
||||
=> growable default types
|
||||
|
||||
