How to upgrade cdist
Update the git installation
To upgrade cdist in the current branch use
.. code-block:: sh
git pull
# Also update the manpages
./build man
export MANPATH=$MANPATH:$(pwd -P)/doc/man
If you stay on a version branche (i.e. 1.0, 1.1., ...), nothing should break.
The master branch on the other hand is the development branch and may not be
working, break your setup or eat the tree in your garden.
Safely upgrading to new versions
To upgrade to **any** further cdist version, you can take the
following procedure to do a safe upgrade:
.. code-block:: sh
# Create new branch to try out the update
git checkout -b upgrade_cdist
# Get latest cdist version in git database
git fetch -v
# see what will happen on merge - replace
# master with the branch you plan to merge
git diff upgrade_cdist..origin/master
# Merge the new version
git merge origin/master
Now you can ensure all custom types work with the new version.
Assume that you need to go back to an older version during
the migration/update, you can do so as follows:
.. code-block:: sh
# commit changes
git commit -m ...
# go back to original branch
git checkout master
After that, you can go back and continue the upgrade:
.. code-block:: sh
# git checkout upgrade_cdist
Update the python package
To upgrade to the lastet version do
.. code-block:: sh
pip install --upgrade cdist
General update instructions
Updating from 3.0 to 3.1
The type **\_\_ssh_authorized_keys** now also manages existing keys,
not only the ones added by cdist.
Updating from 2.3 to 3.0
The **changed** attribute of objects has been removed.
Use `messaging </software/cdist/man/3.0.0/man7/cdist-messaging.html>`_ instead.
Updating from 2.2 to 2.3
No incompatibilities.
Updating from 2.1 to 2.2
Starting with 2.2, the syntax for requiring a singleton type changed:
Old format:
.. code-block:: sh
require="__singleton_type/singleton" ...
New format:
.. code-block:: sh
require="__singleton_type" ...
Internally the "singleton" object id was dropped to make life more easy.
You can probably fix your configuration by running the following code
snippet (currently untested, please report back if it works for you):
.. code-block:: sh
find ~/.cdist/* -type f -exec sed -i 's,/singleton,,' {} \;
Updating from 2.0 to 2.1
Have a look at the update guide for [[2.0 to 2.1|2.0-to-2.1]].
* Type **\_\_package* and \_\_process** use --state **present** or **absent**.
The states **removed/installed** and **stopped/running** have been removed.
Support for the new states is already present in 2.0.
* Type **\_\_directory**: Parameter --parents and --recursive are now boolean
The old "yes/no" values need to be removed.
* Type **\_\_rvm_ruby**: Parameter --default is now boolean
The old "yes/no" values need to be removed.
* Type **\_\_rvm_gemset**: Parameter --default is now boolean
The old "yes/no" values need to be removed.
* Type **\_\_addifnosuchline** and **\_\_removeline** have been replaced by **\_\_line**
* The **conf** directory is now located at **cdist/conf**.
You need to migrate your types, explorers and manifests
manually to the new location.
* Replace the variable **\_\_self** by **\_\_object_name**
Support for the variable **\_\_object_name** is already present in 2.0.
* The types **\_\_autofs**, **\_\_autofs_map** and **\_\_autofs_reload** have been removed
(no maintainer, no users)
* Type **\_\_user**: Parameter --groups removed (use the new \_\_user_groups type)
* Type **\_\_ssh_authorized_key** has been replaced by more flexible type
Updating from 1.7 to 2.0
* Ensure python (>= 3.2) is installed on the source host
* Use "cdist config host" instead of "cdist-deploy-to host"
* Use "cdist config -p host1 host2" instead of "cdist-mass-deploy"
* Use "cdist banner" for fun
* Use **\_\_object_name** instead of **\_\_self** in manifests
Updating from 1.6 to 1.7
* If you used the global explorer **hardware_type**, you need to change
your code to use **machine** instead.
Updating from 1.5 to 1.6
* If you used **\_\_package_apt --preseed**, you need to use the new
type **\_\_debconf_set_selections** instead.
* The **\_\_package** types accepted either --state deinstalled or
--state uninstaaled. Starting with 1.6, it was made consistently
to --state removed.
Updating from 1.3 to 1.5
No incompatibilities.
Updating from 1.2 to 1.3
Rename **gencode** of every type to **gencode-remote**.
Updating from 1.1 to 1.2
No incompatibilities.
Updating from 1.0 to 1.1
In 1.1 the type **\_\_file** was split into **\_\_directory**, **\_\_file** and
**\_\_link**. The parameter **--type** was removed from **\_\_file**. Thus you
need to replace **\_\_file** calls in your manifests:
* Remove --type from all \_\_file calls
* If type was symlink, use \_\_link and --type symbolic
* If type was directory, use \_\_directory
