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 enable 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 are
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 using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
Contents
- 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. -
SUCCESS- This condition is the same asCOMPLETE, but it also requires that the container exits with azerostatus. -
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.
