dependsOn

Establishes dependencies between this container and the status of other containers in the same container group. A container can have dependencies on multiple different containers.

.

You can use dependencies to establish a startup/shutdown sequence across the container group. For example, you might specify that ContainerB has a START dependency on ContainerA. This dependency means that ContainerB can't start until after ContainerA has started. This dependency is reversed on shutdown, which means that ContainerB must shut down before ContainerA can shut down.
