Init containers support all the fields and features of app containers, including resource limits, volumes, and security settings. However, the resource requests and limits for an init container are handled differently, as documented in [Resources](#resources).

Also, init containers do not support readiness probes because they must run to completion before the Pod can be ready. Also, init containers do not support `lifecycle`, `livenessProbe`, `readinessProbe`, or `startupProbe` because they must run to completion before the Pod can be ready.
If you specify multiple init containers for a Pod, Kubelet runs each init container sequentially. Each init container must succeed before the next can run. When all of the init containers have run to completion, Kubelet initializes the application containers for the Pod and runs them as usual.

Init 容器支持应用容器的全部字段和特性，包括资源限制、数据卷和安全设置。 然而，Init 容器对资源请求和限制的处理稍有不同，在下面 [资源](#资源) 处有说明。 Init 容器支持应用容器的全部字段和特性，包括资源限制、数据卷和安全设置。 然而，Init 容器对资源请求和限制的处理稍有不同，在下面 [资源](#资源) 处有说明。

如果为一个 Pod 指定了多个 Init 容器，这些容器会按顺序逐个运行。每个 Init 容器必须运行成功，下一个才能够运行。当所有的 Init 容器运行完成时，Kubernetes 才会为 Pod 初始化应用容器并像平常一样运行。 如果为一个 Pod 指定了多个 Init 容器，这些容器会按顺序逐个运行。每个 Init 容器必须运行成功，下一个才能够运行。当所有的 Init 容器运行完成时，Kubernetes 才会为 Pod 初始化应用容器并像平常一样运行。
