The process of safely evicting {{< glossary_tooltip text="Pods" term_id="pod" >}} from a {{< glossary_tooltip text="Node" term_id="node" >}} to prepare it for maintenance or removal from a {{< glossary_tooltip text="cluster" term_id="cluster" >}}.

|
|
The `kubectl drain` command is used to mark a {{< glossary_tooltip text="Node" term_id="node" >}} as going out of service.
|
|
When executed, it evicts all {{< glossary_tooltip text="Pods" term_id="pod" >}} from the {{< glossary_tooltip text="Node" term_id="node" >}}.
|
|
If an eviction request is temporarily rejected, `kubectl drain` retries until all {{< glossary_tooltip text="Pods" term_id="pod" >}} are terminated or a configurable timeout is reached.
