Subscription

How to debug a failing Subscription

The Catalog operator will constantly update the Status of Subscription to reflect its current state. You can check the Status of your Subscription with the following command:

$ kubectl -n my-namespace get subscriptions my-subscription -o yaml | yq r - status

Note: It is possible that the Status is missing, which suggests that the Catalog operator is encountering an issue when processing the Subscription in a very early stage.

If the Status block does not provide enough information, check the Catalog operator’s logs.

A subscription in namespace X can’t install operators from a CatalogSource in namespace Y

Subscriptions cannot install operators provided by CatalogSources that are not in the same namespace unless the CatalogSource is created in the olm namespace.

Why does a single failing subscription cause all subscriptions in a namespace to fail?

Each Subscription in a namespace acts as a part of a set of operators for the namespace - think of a Subscription as an entry in a python requirements.txt. If OLM is unable to resolve part of the set, it knows that resolving the entire set will fail, so it will bail out of the installation of operators for that particular namespace. Subscriptions are separate objects but within a namespace they are all synced and resolved together.
