Jenkins is a solid CI tool that automates building, testing, and deploying software, making continuous integration and delivery easier. One of its biggest strengths is self-service—anyone on the team can tweak and customize it with its extensive library of 1800+ plugins, with little to no red tape.

But while giving your team the freedom to work their way is great, it also comes with risks. Without the right balance of compliance, visibility, and stability, your Jenkins setup can spiral out of control fast.

The hard truth? The same self-service flexibility that makes Jenkins so useful is often what leads to its downfall. If you don’t keep an eye on it, your Jenkins instance can quickly turn into a mess.

The Gap Between “Self-Service” and “Required Expertise” 

Teams that use Jenkins as it was originally intended (as a project-specific, expert-managed CI server) don’t experience these problems at first. The Jenkins expert(s) sets up Jenkins quickly and provides basic self-service options for everyone.

However, things quickly turn chaotic since Jenkins encourages users to expand its capabilities through their large selection of plugins. And that’s where the problem starts. Most teams end up with Jenkins configurations much more complex than the average dev can handle.

This turns your Jenkins experts into a bottleneck.

To bypass the bottleneck, other team members will try to maintain the server themselves or will just create a separate Jenkins install someplace else…and this process repeats itself over and over… This creates complications and chaos. Jenkins is constantly being added to and Jenkins projects are distributed in a non-systematic way.

All of this ends up being very expensive. Your Jenkins people have created more of a blocker than Jenkins itself. Sounds a lot like pre-DevOps, manual processes, doesn’t it?

Self-service can be too much of a good thing

Jenkins is a by-design “democratic,” self-empowering tool, allowing anyone to create projects, configure agents, install plugins, etc. But like anything, too much of any good thing can go bad. Too much self-service can cause problems: speed, vulnerability, and longevity.

Because anyone can install any plugin, odds are that you won’t know who installed a plugin, why they installed it, how often it’s being used, or whether it can be removed without breaking anything; Jenkins doesn’t indicate any of this. In fact, some plugins get automatically added because another plugin requires that plugin.

If a less-thorough colleague doesn’t seek answers to ALL these questions from the people who installed them and modifies or deletes a plugin, your stuff can break. And if all these plugins are on your controller, you end up with a sluggish Jenkins that may result in more failed builds.

Because anyone can install any plugin—which is not of equal quality—it’s too easy to introduce vulnerabilities or even malware into your Jenkins installations. To avoid this, perhaps you’ll require your developers to get approval and advice on installing plugins from Jenkins expert… which makes the Jenkins expert a bottleneck again.

And when your information relies on human memory and manual intervention for updates, your Jenkins pipelines become “legacy” much faster than competing tools’ pipelines.

The Solution

If you’re reading this, you probably already know the headaches that come with self-service in Jenkins and are looking for a fix. But don’t ditch Jenkins just yet! Replacing it would be expensive, and your team already knows how to use it.

Instead, pair it with a dedicated tool like BuildMaster—it can solve your Jenkins issues while improving your overall CI/CD process. The best way to escape Jenkins chaos is to use a tool that integrates seamlessly with it.

Here’s how BuildMaster gets self-service right.

Self-Service Done Right

1. Restriction: Environment Targeting

Management can restrict deployment to target a pre-specified environment. This control can be applied in a few ways:

• Permissions: users must have permission to deploy to that environment in order to deploy to that stage
• Role Selection Filtering: if you also target by role, then the server must be in that environment to be included
• Runtime Server Protection: a server must be in the target environment, or a runtime error will occur
• Visualization: this helps you see which builds have been deployed to which environments

2. Restriction: Server Targeting

Server targeting restriction can be applied in multiple ways:

• No default server context; this means you will need to explicitly specify which servers to deploy to in the deployment plan itself
• All servers in target environment; this will run the deployment plan against all servers in the targeted environment
• Specific servers; the plan will be run against the list of servers specified
• Specific server roles; the plan will be run against servers with the specified roles that are associated with the targeted environment
• Server Pool; the plan will run against one server from a specified role that will act as a pool. This will effectively put an Acquire-Server operation at the beginning of the plan.

3. Restriction: Release/Job Templates 

• Management can define key/value pairs on pipelines and/or stages. These behave just like configuration variables, in that you can use these variables within deployment plans that are executed through the plan.
• However, unlike configuration variables, pipeline variables, cannot be multi-scoped, and cannot be modified through the variables API.

4. Restriction: Manual Pipeline Stage Approvals

• To prevent a build with any failing unit tests from being deployed to a pipeline stage, management can add a “Unit Test” automated approval to the target stage. This approval will validate that tests recorded in the latest execution to the previous pipeline stage either all passed or none failed, where inconclusive tests are dependent upon the approval’s configuration.

Conclusion

Jenkins is a self-service-oriented tool that your team should continue to use. However, it’s so important to introduce restrictions that balance self-service with stability, visibility, and compliance. The easiest way to do this is to use a tool like BuildMaster. 

All BuildMaster features are designed as much for the casual user as for the power user. BuildMaster was designed to integrate well with nearly every other DevOps tool you might be using. It’s mature enough for experts but accessible enough to enable self-service for non-experts.
