f9ee64007e apf: always create missing bootstrap configuration object(s) 2021-05-17 12:08:39 -04:00

759a64136b add auto update for apf bootstrap configuration
Take the following approach:
On a fresh install, all bootstrap configuration objects will
have auto update enabled via the following annotation :
`apf.kubernetes.io/autoupdate: 'true'`

The kube-apiserver periodically checks the bootstrap configuration
objects on the cluster and applies update if necessary.

We enforce an 'always auto-update' policy for the mandatory
configuration object(s).

We update the suggested configuration objects when:
- auto update is enabled (`apf.kubernetes.io/autoupdate: 'true'`) or
- auto update annotation key is missing but `generation` is `1`

If the configuration object is missing the annotation key, we add
it appropriately:
it is set to `true` if `generation` is `1`, `false` otherwise.

The above approach ensures that we don't squash changes made by an
operator. Please note, we can't protect the changes made by the
operator in the following scenario:
- the user changes the spec and then deletes and recreates
  the same object. (generation resets to 1)
