Implementations
The deployment circuit breaker can only be used for services using the rolling
update (ECS
) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
If a service is using the rolling update (ECS
) deployment type, the
maximum percent parameter represents an upper limit
on the number of tasks in a service that are allowed in the RUNNING
or
PENDING
state during a deployment, as a percentage of the desired
number of tasks (rounded down to the nearest integer), and while any container instances
are in the DRAINING
state if the service contains tasks using the
EC2 launch type. This parameter enables you to define the deployment batch
size. For example, if your service has a desired number of four tasks and a maximum
percent value of 200%, the scheduler may start four new tasks before stopping the four
older tasks (provided that the cluster resources required to do this are available). The
default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY
) or
EXTERNAL
deployment types and tasks that use the EC2
launch type, the maximum percent value is set to the
default value and is used to define the upper limit on the number of the tasks in the
service that remain in the RUNNING
state while the container instances are
in the DRAINING
state. If the tasks in the service use the
Fargate launch type, the maximum percent value is not used, although it is
returned when describing your service.

If a service is using the rolling update (ECS
) deployment type, the
minimum healthy percent represents a lower limit on
the number of tasks in a service that must remain in the RUNNING
state
during a deployment, as a percentage of the desired number of tasks (rounded up to the
nearest integer), and while any container instances are in the DRAINING
state if the service contains tasks using the EC2 launch type. This
parameter enables you to deploy without using additional cluster capacity. For example,
if your service has a desired number of four tasks and a minimum healthy percent of 50%,
the scheduler may stop two existing tasks to free up cluster capacity before starting
two new tasks. Tasks for services that do not use a load balancer
are considered healthy if they are in the RUNNING
state; tasks for services
that do use a load balancer are considered healthy if they are in
the RUNNING
state and they are reported as healthy by the load balancer.
The default value for minimum healthy percent is 100%.
