All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<ContainerDependency.Builder,ContainerDependency>

@Generated(value="software.amazon.awssdk:codegen")
public final class ContainerDependency
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<ContainerDependency.Builder,ContainerDependency>

The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.

Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

For tasks that use the Fargate launch type, the task or service requires the following platforms:

• Linux platform version 1.3.0 or later.

• Windows platform version 1.0.0 or later.

Method Detail

containerName

public final String containerName()

The name of a container.

Returns:

The name of a container.

condition

public final ContainerCondition condition()

The dependency condition of the container. The following are the available conditions and their behavior:

• START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

• COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

• SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

• HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.

If the service returns an enum value that is not available in the current SDK version, condition will return ContainerCondition.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from conditionAsString().

Returns:

The dependency condition of the container. The following are the available conditions and their behavior:

• START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

• COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

• SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

• HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
