Always ensure that you have one decK process running at any time. Multiple
processes step on each other and can corrupt Kong’s configuration.
Do not mix up decK’s declarative configuration with cURL or any other
script. Either manage the configuration with decK or manage it with your
homegrown script. Mixing the two on the same dataset is cumbersome and error-prone.
If you have a very large installation, you can split out
your configuration into smaller subsets. You can find more info for it
in the guide to practicing
Always use a pinned version of decK and Kong.
Use a specific version of decK in production to achieve declarative
configuration. If you upgrade to a new version of decK or Kong,
please safely test the changes in a staging environment first.
decK does not manage encryption of sensitive information. The state file
stores the private keys of your certificates and credentials of consumers in
plaintext. Be careful in how and where you store
this file to avoid any security breaches.
Always store the sensitive information in an encrypted form and provide a plaintext
version of it on a need-only basis.
If you have many consumers in your database, do not export
or manage them using decK. Declarative configuration is only meant for entity
configuration. It is not meant for end-user data, which can easily grow into
hundreds of thousands or millions of records.
Always run a deck diff command before running a deck sync
to ensure that the change is correct.
Always secure Kong’s Admin API with a reliable authentication method.
Do not write the state file by hand to avoid errors.
Use Kong’s Admin API to configure Kong for the first time, then
export the configuration to a declarative configuration file. Any
subsequent changes should be made by manually editing the file and pushing
the change via CI. If you’re making a larger change, make the change in Kong first, then
export the new file. Then you can diff the two state files to review the changes
Configure a cronjob to run deck diff periodically to ensure that Kong’s
database is in sync with the state file checking into your Git repositories.
Trigger an alert if decK detects a drift in the configuration.
