Manage Konnect and Kong Gateway configuration declaratively
decK helps manage Kong’s configuration in a declarative fashion. This means that
a developer can define the desired state of Kong Gateway or Konnect –
services, routes, plugins, and more – and let decK handle implementation
without needing to execute each step manually, as you would with the Kong Admin
- Sync configuration to a running Kong cluster
- diff configuration to detect any drift or manual changes
- Back up your instance’s configuration
- Manage Kong’s configuration in a distributed way using tags, helping you split
the configuration across various teams
View our introductory screencast explaining decK.
Export: Export Kong configuration to a YAML configuration file.
This feature is especially useful for backing up Kong’s configuration.
Import: Populate Kong’s database using a previously exported or
manually written configuration file.
Diff and sync capabilities: decK can diff the configuration between the
provided configuration file and Kong’s database, then sync the configs based on
the diff. This feature is particularly useful for detecting config drifts or
Reverse sync: decK also supports sync in the opposite direction, meaning
that if an entity is created in Kong and isn’t added to the config file,
decK will detect the change.
Validation: decK can validate YAML files that you backup or modify to
catch errors early on.
Reset: decK can completely reset Kong’s database by deleting all entities.
Parallel operations: All Admin API calls to Kong are executed in parallel
using multiple threads to speed up the sync process.
Authentication with Kong: Custom HTTP headers can be injected in requests
to Kong’s Admin API for authentication or authorization purposes.
Manage Kong’s config with multiple config files: Split your configuration
into multiple logical files based on a shared set of tags amongst entities.
Designed to automate configuration management: decK is designed to be part
of your CI pipeline, where it can push configuration to Kong and detect drifts
decK is compatible with Kong Gateway (OSS) >= 1.x and
Kong Gateway >= 0.35.
