      Parameters:
      scope - This parameter is required.
      id - This parameter is required.
      Returns:
      a new instance of ManagedEc2EcsComputeEnvironment.Builder.

    • computeEnvironmentName

      @Stability(Stable) public ManagedEc2EcsComputeEnvironment.Builder computeEnvironmentName(String computeEnvironmentName)
      The name of the ComputeEnvironment.

      Default: - generated by CloudFormation

      Parameters:
      computeEnvironmentName - The name of the ComputeEnvironment. This parameter is required.
      Returns:
      this

    • enabled

      @Stability(Stable) public ManagedEc2EcsComputeEnvironment.Builder enabled(Boolean enabled)
      Whether or not this ComputeEnvironment can accept jobs from a Queue.

      Enabled ComputeEnvironments can accept jobs from a Queue and can scale instances up or down. Disabled ComputeEnvironments cannot accept jobs from a Queue or scale instances up or down.

      If you change a ComputeEnvironment from enabled to disabled while it is executing jobs, Jobs in the STARTED or RUNNING states will not be interrupted. As jobs complete, the ComputeEnvironment will scale instances down to minvCpus.

      To ensure you aren't billed for unused capacity, set minvCpus to 0.

      Default: true

      Parameters:
      enabled - Whether or not this ComputeEnvironment can accept jobs from a Queue. This parameter is required.
      Returns:
      this

    • replaceComputeEnvironment

      @Stability(Stable) public ManagedEc2EcsComputeEnvironment.Builder replaceComputeEnvironment(Boolean replaceComputeEnvironment)
      Specifies whether this Compute Environment is replaced if an update is made that requires replacing its instances.

      To enable more properties to be updated, set this property to false. When changing the value of this property to false, do not change any other properties at the same time. If other properties are changed at the same time, and the change needs to be rolled back but it can't, it's possible for the stack to go into the UPDATE_ROLLBACK_FAILED state. You can't update a stack that is in the UPDATE_ROLLBACK_FAILED state. However, if you can continue to roll it back, you can return the stack to its original settings and then try to update it again.

      The properties which require a replacement of the Compute Environment are:

      Default: false

      Parameters:
      replaceComputeEnvironment - Specifies whether this Compute Environment is replaced if an update is made that requires replacing its instances. This parameter is required.
