The Blueprint for a Smooth Release Engineering Process#

Isn’t it satisfying when everything falls into place just as you’d hoped? In the complex world of development, where multiple cogs are in motion at any given time, having a well-defined plan can make all the difference. Here’s a streamlined guide to setting up a robust Release Engineering (Releng) system that ensures efficient and error-free deployments.

Step-by-Step Implementation#

1. Version Control with Git#

We begin by storing all our configuration files and Puppet manifests in a Git repository. It serves as the central hub where changes are tracked and updated.

To disable a service, you must be root or have sudo privileges.

For example, to disable the Puppet service, you would run the following command:

svcadm disable network/cswpuppetd:default

This will disable the Puppet service and prevent it from running.

To verify that the service has been disabled, you can run the following command:

svcs | grep puppet

This will list all of the services that are currently running, and if the Puppet service is disabled, it will not be listed.

How to Solve the Puppet Error: Could not find class in namespace#

Sometimes, when working with Puppet, you may encounter an error message that does not accurately reflect the actual problem. For example, if you see this error:

err: Could not retrieve catalog: Could not find class php in namespaces standardbuild at /etc/puppet/manifests/templates.pp:15 on domain.internal.com

One of the possible causes could be a missing curly bracket in your code. This can be hard to spot and can waste a lot of your time. To avoid this, make sure you check your syntax carefully and use a code editor that can highlight any errors for you.
