One or more initialization containers that must run to completion before any app containers run.

One or more initialization [containers](#gloss: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 [sidecar containers](#gloss:sidecar-container), init containers do not remain running after Pod startup.
