Jenkins build automation
Self-hosted automation for builds that must run inside your own network.
CI/CD
Chosen per project
Maintainable handover
Jenkins remains widely deployed for a specific reason: it runs where you put it. When builds need access to internal systems, licensed tooling or hardware, or when code cannot leave the network, a hosted CI service is not an option.
The cost is that Jenkins is infrastructure you now own — plugins, upgrades, agents and backups. That is manageable when pipelines are defined as code in the repository rather than clicked together in the interface, which is the difference between a maintainable installation and the ones people dread.
What we build with Jenkins
Builds requiring access to internal networks or licensed tools
Organisations that cannot use a cloud CI service
Existing Jenkins installations needing modernisation
Pipelines across mixed Windows and Linux agents
Where it fits — and where it does not
Good fit when
Self-hosted requirements
Complex builds with unusual toolchain needs
Teams with existing Jenkins investment and knowledge
Consider something else when
New projects with no self-hosting constraint — hosted CI is far less to run
Small teams without capacity to maintain the controller
What separates a healthy Jenkins from a feared one
Every item here is about removing state that exists only inside the installation.
Jenkinsfile in the repo
The pipeline is reviewable and versioned.
Agents from images
No hand-tuned machines nobody dares touch.
Plugins minimised
Fewer upgrades that break everything at once.
Config backed up
The controller can be rebuilt, not just restored to.
How we work with Jenkins
Pipelines as code
Declarative Jenkinsfiles in the repository, so pipeline changes are reviewed and no configuration lives only in the UI.
Disposable agents
Build agents created from images rather than hand-configured, so a rebuilt agent behaves identically.
Credentials managed properly
Secrets in the credentials store, masked in logs, scoped to the jobs that need them.
Controller kept lean
No builds on the controller, plugins kept to what is used, and configuration backed up.
Our typical Jenkins setup
| Concern | What we use |
|---|---|
| Pipelines | Declarative Jenkinsfile, stored with the code |
| Agents | Ephemeral Docker or VM agents from a base image |
| Credentials | Credentials plugin with scoped, masked secrets |
| Upgrades | Controlled plugin and core update schedule |
| Backup | Configuration and job definitions backed up and restorable |
Frequently asked questions
If nothing forces you to self-host, a hosted service usually costs less in total. If internal network access or policy requires it, a well-configured Jenkins is entirely respectable.
Usually, by moving job definitions into Jenkinsfiles in the repositories one at a time, so the installation stops being the only place the truth lives.
Yes. Self-hosting the controller does not restrict deployment targets.
Services built with Jenkins
Enterprise Software Development
Systems for organisations where several departments, sites and approval chains all have to work from the same data.
Custom Software Development
Software shaped around the way your business already works, instead of a packaged product you have to reorganise around.
Software Maintenance
Keeping working systems working — including ones built by somebody else.
Cloud Solutions
Hosting designed around what your application actually needs, with the monitoring and backups that make it safe to rely on.
