I spent some time tackling technical debt in our Puppet code this week. The biggest outstanding item was implementing eyaml for protecting secrets in Hiera. I’d also been encouraging developers to contribute to the Puppet code base for some time, but they were restricted from the control repo due to some secrets kept in Hiera. This put a big damper on collaboration as Hiera is the data engine for our roles and profiles. Separate git repos were also used for the profile and role modules due to this workflow.
created a new branch on the existing control repo
moved the roles and profiles modules into the site directory of the control repo
create an environment.conf file to add the site dir to the module path
tested an r10k run on the new environment
spent some time fighting RSpec, as you do
merged into production
created a new git repo for the control module to remove commit history containing secrets
opened up access to the development team
We’ve now got a control repo with encrypted secrets open to contributions from across the org. I’m also enjoying the simplified workflow with environments now that hieradata, roles, and profiles are all in a single git repo.
