Chef 13 Upgrade: Rubocop Changes for lazy Parameters
As part of an upgrade from Chef 12 to Chef 13, this is one of the posts in which I've been detailing the issues I've encountered, and how I've resolved them .
When running Rubocop from ChefDK 2 against the following code, we receive the error Parenthesize the param lazy { ... } to make sure that the block will be associated with the lazy method call twice:
template 'Chef deploy user\'s authorized_keys' do
source 'authorized_keys.erb'
path lazy { "#{node['etc']['passwd']['chef']['dir']}/.ssh/authorized_keys" }
user 'chef'
group 'chef'
mode '0600'
variables lazy {
{
public_keys: node['authorized_keys'] + [node.run_state['public_key/deploy']]
}
}
end
This error can be resolved by adding a parentheses around the whole lazy { } blocks:
template 'Chef deploy user\'s authorized_keys' do
source 'authorized_keys.erb'
- path lazy { "#{node['etc']['passwd']['chef']['dir']}/.ssh/authorized_keys" }
+ path(lazy { "#{node['etc']['passwd']['chef']['dir']}/.ssh/authorized_keys" })
user 'chef'
group 'chef'
mode '0600'
- variables lazy {
+ variables(lazy do
{
public_keys: node['authorized_keys'] + [node.run_state['public_key/deploy']]
}
- }
+ end)
end
Note that I've also converted the multi-line block to a do / end block, as that was another complaint of Rubocop.
