INTRODUCTION</h2></div></div></div><p>This document describes the usual steps recommended for a new
|
|||
|
|
cdist setup. It is recommended that you have read and understood
|
|||
|
|
cdist-quickstart(7) before digging into this.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_location"></a>3. LOCATION</h2></div></div></div><p>First of all, you should think about where to store your configuration
|
|||
|
|
database and who will be accessing or changing it. Secondly you have to
|
|||
|
|
think about where to configure your hosts from, which may be a different
|
|||
|
|
location.</p><p>For starters, having cdist (which includes the configuration database) on
|
|||
|
|
your notebook should be fine.
|
|||
|
|
Additionally an external copy of the git repository the configuration
|
|||
|
|
relies in is recommended, for use as backup as well to allow easy collaboration
|
|||
|
|
with others.</p><p>For more sophisticated setups developing cdist configurations with multiple
|
|||
|
|
people, have a look at cdist-best-practice(7).</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_setup_working_directory_and_branch"></a>4. SETUP WORKING DIRECTORY AND BRANCH</h2></div></div></div><p>I assume you have a fresh copy of the cdist tree in ~/cdist, cloned from
|
|||
|
|
one of the official urls (see cdist-quickstart(7) if you don’t).
|
|||
|
|
Entering the command "git branch" should show you "* master", which indicates
|
|||
|
|
you are on the <span class="strong"><strong>master</strong></span> branch.</p><p>The master branch reflects the latest development of cdist. As this is the
|
|||
|
|
development branch, it may or may not work. There are also version branches
|
|||
|
|
available, which are kept in a stable state. Let’s use <span class="strong"><strong>git branch -r</strong></span>
|
|||
|
|
to list all branches:</p><pre class="screen">cdist% git branch -r
|
|||
|
|
origin/1.0
|
|||
|
|
origin/1.1
|
|||
|
|
origin/1.2
|
|||
|
|
origin/1.3
|
|||
|
|
origin/1.4
|
|||
|
|
origin/1.5
|
|||
|
|
origin/1.6
|
|||
|
|
origin/1.7
|
|||
|
|
origin/2.0
|
|||
|
|
origin/HEAD -> origin/master
|
|||
|
|
origin/archive_shell_function_approach
|
|||
|
|
origin/master</pre><p>So <span class="strong"><strong>2.0</strong></span> is the latest version branch in this example.
|
|||
|
|
All versions (2.0.x) within one version branch (2.0) are compatible to each
|
|||
|
|
other and won’t break your configuration when updating.</p><p>It’s up to you to decide which branch you want to base your own work on:
|
|||
|
|
master contains more recent changes, newer types, but may also break.
|
|||
|
|
The version branches are stable, but may lack the latest features.
|
|||
|
|
Your decision can be changed later on, but may result in merge conflicts,
|
|||
|
|
which you will need to solve.</p><p>Let’s assume you want latest stuff and select the master branch as base for
|
|||
|
|
your own work. Now it’s time to create your branch, which contains your
|
|||
|
|
local changes. I usually name it by the company/area I am working for:
|
|||
|
|
ethz-systems, localch, customerX, … But this is pretty much up to you.</p><p>In this tutorial I use the branch <span class="strong"><strong>mycompany</strong></span>:</p><pre class="screen">cdist% git checkout -b mycompany origin/master
|
|||
|
|
Branch mycompany set up to track remote branch master from origin.
|
|||
|
|
Switched to a new branch 'mycompany'
|
|||
|
|
cdist-user% git branch
|
|||
|
|
master
|
|||
|
|
* mycompany</pre><p>From now on, you can use git as usual to commit your changes in your own branch.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_publishing_the_configuration"></a>5. PUBLISHING THE CONFIGURATION</h2></div></div></div><p>Usually a development machine like a notebook should be considered
|
|||
|
|
temporary only. For this reason and to enable shareability, the configuration
|
|||
|
|
should be published to another device as early as possible. The following
|
|||
|
|
example shows how to publish the configuration to another host that is
|
|||
|
|
reachable via ssh and has git installed:</p><pre class="screen"># Create bare git repository on the host named "loch"
|
|||
|
|
cdist% ssh loch "GIT_DIR=/home/nutzer/cdist git init"
|
|||
|
|
Initialized empty Git repository in /home/nutzer/cdist/
|
|||
|
|
|
|||
|
|
# Add remote git repo to git config
|
|||
|
|
cdist% git remote add loch loch:/home/nutzer/cdist
|
|||
|
|
|
|||
|
|
# Configure the mycompany branch to push to loch
|
|||
|
|
cdist% git config branch.mycompany.remote loch
|
|||
|
|
|
|||
|
|
# Configure mycompany branch to push into remote master branch
|
|||
|
|
cdist% git config branch.mycompany.merge refs/heads/master
|
|||
|
|
|
|||
|
|
# Push mycompany branch to remote branch master initially
|
|||
|
|
cdist% git push loch mycompany:refs/heads/master</pre><p>Now you have setup the git repository to synchronise the <span class="strong"><strong>mycompany</strong></span>
|
|||
|
|
branch with the <span class="strong"><strong>master</strong></span> branch on the host <span class="strong"><strong>loch</strong></span>. Thus you can commit
|
|||
|
|
as usual in your branch and push out changes by entering <span class="strong"><strong><span class="strong"><strong>git push</strong></span></strong></span>.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_updating_from_origin"></a>6. UPDATING FROM ORIGIN</h2></div></div></div><p>Whenever you want to update your cdist installation, you can use git to do so:</p><pre class="screen"># Update git repository with latest changes from origin
|
|||
|
|
cdist% git fetch origin
|
|||
|
|
|
|||
|
|
# Update current branch with master branch from origin
|
|||
|
|
cdist% git merge origin/master
|
|||
|
|
|
|||
|
|
# Alternative: Update current branch with 2.0 branch from origin
|
|||
|
|
cdist% git merge origin/2.0</pre></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_see_also"></a>7. SEE ALSO</h2></div></div></div><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
