This is a collection of tips for people assisting with FOLIO development operations.

See also some specific DevOps Guides.


These GitHub repositories are utilised for DevOps work. Some are private, therefore only for people with relevant permissions.

Starting points and tips

These are some of the main starting points to assist with FOLIO DevOps work. Use the Search facility for more.

Of course we attend to much more than just the following items.

Collaboration channels

Introduction to the Community and Collaboration tools.

The main Slack channels:

  • #devops-internal – For our group.
  • #devops – For the wider community to ask for DevOps assistance.
  • #hosted-reference-envs – For requests and trouble with the regularly-built reference environments.
  • #support and #development – We encourage developers to seek community support here, leaving the #devops channel for specific DevOps issues.
  • #releases – For release announcements.


Refer to the overview of the Build, test, and deployment infrastructure and notes about Jenkins, Docker, Nexus, etc. .

Reference environments

Explanations of each of the regularly-built reference environments including the build times and links to the relevant Jenkins jobs.

We monitor those builds, triage problems, and try to direct issues back to developers.

We try to limit out-of-band requests to manually rebuild these. Many other people utilise these systems. See Slack #hosted-reference-envs channel. People need to ask there and allow time for others to be aware.

To determine the cause of failed builds, search the Jenkins output logfile. Remember that the cause might be in the earlier build of “Pipeline build-platform-complete-snapshot” etc.

Developer scratch environments

Refer to the overview of How to get started with Rancher environment and Helm.

GitHub and Jenkins access

Developers need access to GitHub repositories and Jenkins.


Note that we try to steer clear of managing GitHub access for individuals. Instead allocate access for a whole Team to a repository.

When enabling a team, then also add it to the “Security and analysis” section, so that they can see and attend to scanning alerts.


For consistently named GitHub repositories, then Jenkins access should be automatic. If not, then visit the “Manage Jenkins : Manage and Assign Roles” section.

Do the “Manage Roles” first, then “Assign Roles”.

The “Manage roles” cannot have multiple patterns, but can handle a broader regex. Do not add the outer double-quotes. The “Add” button is way to the right-hand side.
