Init Container	init-container	2018-04-12	/docs/concepts/workloads/pods/init-containers/	One or more initialization containers that must run to completion before any app containers run.		fundamental

One or more initialization {{< glossary_tooltip text="containers" term_id="container" >}} that must run to completion before any app containers run.

Initialization (init) containers are like regular app containers, with one difference: init containers must run to completion before any app containers can start. Init containers run in series: each init container must run to completion before the next init container begins.

Unlike {{< glossary_tooltip text="sidecar containers" term_id="sidecar-container" >}}, init containers do not remain running after Pod startup.

For more information, read init containers.
