public enum AwsLogDriverMode
extends Enum<AwsLogDriverMode>

awslogs provides two modes for delivering messages from the container to the log driver.

Example:

 Cluster cluster;
 // Create a Task Definition for the container to start
 Ec2TaskDefinition taskDefinition = new Ec2TaskDefinition(this, "TaskDef");
 taskDefinition.addContainer("TheContainer", ContainerDefinitionOptions.builder()
         .image(ContainerImage.fromAsset(resolve(__dirname, "..", "eventhandler-image")))
         .memoryLimitMiB(256)
         .logging(AwsLogDriver.Builder.create().streamPrefix("EventDemo").mode(AwsLogDriverMode.NON_BLOCKING).build())
         .build());
 // An Rule that describes the event trigger (in this case a scheduled run)
 Rule rule = Rule.Builder.create(this, "Rule")
         .schedule(Schedule.expression("rate(1 min)"))
         .build();
 // Pass an environment variable to the container 'TheContainer' in the task
 rule.addTarget(EcsTask.Builder.create()
         .cluster(cluster)
         .taskDefinition(taskDefinition)
         .taskCount(1)
         .containerOverrides(List.of(ContainerOverride.builder()
                 .containerName("TheContainer")
                 .environment(List.of(TaskEnvironmentVariable.builder()
                         .name("I_WAS_TRIGGERED")
                         .value("From CloudWatch Events")
                         .build()))
                 .build()))
         .build());

Enum Constants

Enum Constant	Description
BLOCKING	(default) direct, blocking delivery from container to driver.
NON_BLOCKING	The non-blocking message delivery mode prevents applications from blocking due to logging back pressure.

Method Summary

Modifier and Type	Method	Description
static AwsLogDriverMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static AwsLogDriverMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

BLOCKING

@Stability(Stable)
public static final AwsLogDriverMode BLOCKING

(default) direct, blocking delivery from container to driver.

NON_BLOCKING

@Stability(Stable)
public static final AwsLogDriverMode NON_BLOCKING

The non-blocking message delivery mode prevents applications from blocking due to logging back pressure.

Applications are likely to fail in unexpected ways when STDERR or STDOUT streams block.

Method Details

values

public static AwsLogDriverMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AwsLogDriverMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
