先睹为快

我们通过puppet-openstack-cookiebutter模块的contrib/bootstrap.sh脚本来说明:

# Step 4: Retrieve the puppet-modulesync-configs directory and configure it for your need
#
git clone https://review.openstack.org/openstack/puppet-modulesync-configs
pushd puppet-modulesync-configs/
cat > managed_modules.yml <<EOF
---
  - puppet-$proj
EOF
cat > modulesync.yml <<EOF
---
namespace:
git_base: file://$tmp_var/cookiecutter/
branch: initial_commit
EOF

# Step 5: Run msync and amend the initial commit
#
msync update --noop
pushd modules/puppet-$proj
md5password=`ruby -e "require 'digest/md5'; puts 'md5' + Digest::MD5.hexdigest('pw${proj}')"`
sed -i "s|md5c530c33636c58ae83ca933f39319273e|${md5password}|g" spec/classes/${proj}_db_postgresql_spec.rb
git remote add gerrit ssh://$user@review.openstack.org:29418/openstack/puppet-$proj.git
git add --all && git commit --amend -am "puppet-${proj}: Initial commit

This is the initial commit for puppet-${proj}.
It has been automatically generated using cookiecutter[1] and msync[2]

[1] https://github.com/openstack/puppet-openstack-cookiecutter
[2] https://github.com/openstack/puppet-modulesync-configs
"

echo "

-----------------------------------------------------------------------------------------------------
The new project has been successfully set up.

To submit the initial review please go to ${tmp_var}/puppet-modulesync-configs/modules/puppet-${proj}
and run git review.

Happy Hacking !

通过以上步骤,可以为一个新puppet module同步Gemfile,Rakeflie等文件,其中执行同步操作的关键命令是:

# 注意需要使用gem安装msync命令
msync update

模块讲解

打一个比方,modulesync-config模块类似于Openstack的requirements项目。用于管理Gem包的依赖,Rakefile的配置等等。它有几个重要的文件:

  • config_defaults.yml: 第一层级的键表示模块被管理的文件名

  • .sync.yml: 出现在各自module中,将覆盖config_defaults中的值

  • managed_modules.yml: 被管理的module列表

  • modulesync.yml: 传递到Modulesync命令行的键值对参数对

关于puppet-modulesync-configs的用途比较单一,因此不再深入展开,更详细的解释参见其模块说明
