Wait¶

Wait for a specific condition on one or many resources.

Deprecated syntax

You can specify the resource directly instead of using apiVersion and kind.

This is a deprecated syntax though and will be removed in a future version.

Configuration¶

The full structure of the Wait resource is documented here.

Features¶

Supported features
Bindings support
Outputs support
Templating support
Operation checks support

Clustered resources¶

When used with a clustered resource, the namespace is ignored and is not added to the corresponding kubectl command.

All resources¶

If you don't specify a name or a selector, the wait operation will consider all resources.

Test namespace¶

When used with a namespaced resource, Chainsaw will default the scope to the ephemeral test namespace.

All namespaces¶

When used with a namespaced resource, it is possible to consider all namespaces in the cluster by setting namespace: '*'.
