Red Hat Summit2.2.2.2.2. olm.channel schema
The olm.channel schema defines a channel within a package, the bundle entries that are members of the channel, and the upgrade paths for those bundles.
If a bundle entry represents an edge in multiple olm.channel blobs, it can only appear once per channel.
It is valid for an entry’s replaces value to reference another bundle name that cannot be found in this catalog or another catalog. However, all other channel invariants must hold true, such as a channel not having multiple heads.
예 2.2. olm.channel schema
#Channel: {
schema: "olm.channel"
package: string & !=""
name: string & !=""
entries: [...#ChannelEntry]
}
#ChannelEntry: {
// name is required. It is the name of an `olm.bundle` that
// is present in the channel.
name: string & !=""
// replaces is optional. It is the name of bundle that is replaced
// by this entry. It does not have to be present in the entry list.
replaces?: string & !=""
// skips is optional. It is a list of bundle names that are skipped by
// this entry. The skipped bundles do not have to be present in the
// entry list.
skips?: [...string & !=""]
// skipRange is optional. It is the semver range of bundle versions
// that are skipped by this entry.
skipRange?: string & !=""
}
When using the skipRange field, the skipped Operator versions are pruned from the update graph and are longer installable by users with the spec.startingCSV property of Subscription objects.
You can update an Operator incrementally while keeping previously installed versions available to users for future installation by using both the skipRange and replaces field. Ensure that the replaces field points to the immediate previous version of the Operator version in question.
