Supported features

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: '*'.
