Note
This external pillar has been rewritten for the 2015.8.0
release. The old method of configuring this
external pillar will be maintained for a couple releases, allowing time for
configurations to be updated to reflect the new usage.
This external pillar allows for a Pillar top file and Pillar SLS files to be sourced from a git repository.
However, since git_pillar does not have an equivalent to the
pillar_roots
parameter, configuration is slightly different. The
Pillar top file must still contain the relevant environment, like so:
base:
'*':
- foo
The branch/tag which maps to that environment must then be specified along with the repo's URL. Configuration details can be found below.
For Salt releases earlier than 2015.8.0
,
GitPython is the only supported provider for git_pillar. Individual
repositories can be configured under the ext_pillar
configuration parameter like so:
ext_pillar:
- git: master https://gitserver/git-pillar.git root=subdirectory
The repository is specified in the format <branch> <repo_url>
, with an
optional root
parameter (added in the 2014.7.0 release) which allows the pillar SLS files to be
served up from a subdirectory (similar to gitfs_root
in gitfs).
To use more than one branch from the same repo, multiple lines must be
specified under ext_pillar
:
ext_pillar:
- git: master https://gitserver/git-pillar.git
- git: dev https://gitserver/git-pillar.git
To remap a specific branch to a specific Pillar environment, use the format
<branch>:<env>
:
ext_pillar:
- git: develop:dev https://gitserver/git-pillar.git
- git: master:prod https://gitserver/git-pillar.git
In this case, the develop
branch would need its own top.sls
with a
dev
section in it, like this:
dev:
'*':
- bar
The master
branch would need its own top.sls
with a prod
section in
it:
prod:
'*':
- bar
If __env__
is specified as the branch name, then git_pillar will use the
branch specified by gitfs_base
:
ext_pillar:
- git: __env__ https://gitserver/git-pillar.git root=pillar
The corresponding Pillar top file would look like this:
{{env}}:
'*':
- bar
Beginning with Salt version 2015.8.0, pygit2 is now supported for git_pillar, in addition to GitPython (Dulwich will not be supported for the forseeable future). The requirements for GitPython and pygit2 are the same as for gitfs, as described here.
Here is an example git_pillar configuration.
ext_pillar:
- git:
- production https://gitserver/git-pillar.git:
- env: prod
- develop https://gitserver/git-pillar.git:
- env: dev
- qa https://gitserver/git-pillar.git
- master https://other-git-server/pillardata.git
- root: pillar
The main difference between this and the old way of configuring git_pillar is
that multiple remotes can be configured under one git
section under
ext_pillar
. More than one git
section can be used, but it is
not necessary. Remotes will be evaluated sequentially.
Per-remote configuration parameters are supported (similar to gitfs), and global versions of the git_pillar configuration parameters can also be set.
With the addition of pygit2 support, git_pillar can now interact with
authenticated remotes. Authentication works just like in gitfs (as outlined in
the GitFS Walkthrough), only with the global
authenication parameter names prefixed with git_pillar
instead of gitfs
(e.g. git_pillar_pubkey
, git_pillar_privkey
,
git_pillar_passphrase
, etc.).
A full list of the git_pillar configuration options can be found here.
