Chef is a powerful configuration management tool used to automate the deployment, configuration, and management of servers. It allows developers and system administrators to define infrastructure as code, ensuring consistency and repeatability across environments. Chef uses recipes and cookbooks to define the desired state of systems, making it easier to manage complex infrastructures.
When working with Chef, you might encounter the CHEF-010 error code, which indicates a resource conflict. This error typically manifests when Chef detects multiple resources attempting to manage the same system component, leading to ambiguity in the desired state.
The CHEF-010 error arises when there are conflicting resource declarations within your Chef recipes. This can happen if two or more resources are trying to manage the same aspect of the system, such as a file or a package, with different attributes or actions. This conflict prevents Chef from determining the correct state to enforce.
Consider a scenario where two recipes are attempting to manage the same configuration file but with different content or permissions. This will trigger a CHEF-010 error, as Chef cannot resolve which version of the file should be applied.
Resolving the CHEF-010 error involves identifying and eliminating the conflicting resource declarations. Follow these steps to address the issue:
Start by reviewing the recipes in your cookbooks to identify where the conflicting resources are declared. Look for resources that manage the same system component, such as:
file '/etc/config_file' do
content 'Configuration A'
action :create
end
file '/etc/config_file' do
content 'Configuration B'
action :create
end
Once identified, consolidate the resource declarations to ensure only one resource manages the component. For example, merge the file resource declarations:
file '/etc/config_file' do
content 'Final Configuration'
action :create
end
After making changes, run your Chef client to test the updated recipes. Ensure that the error no longer occurs and that the desired state is correctly applied.

By following these steps, you can effectively resolve the CHEF-010 error and ensure your Chef recipes are conflict-free, leading to smoother deployments and system management.
