Setting up Java SDK with AWS CDK
AWS CDK
Add the
THUNDRA_APIKEY environment variable along with your Thundra API key.import software.amazon.awscdk.core.Construct;
import software.amazon.awscdk.services.lambda.Function
public class YourConstructClass extends Construct {
String thundraApiKey = <YOUR THUNDRA API KEY>;
public YourConstructClass(Construct scope, String id) {
Function function = Function.Builder.create(this, "YourFunction")
... // other function properties
.environment(new HashMap<String, String>() {{
... // other environment variables
put("THUNDRA_APIKEY", thundraApiKey);
}})
.build();
}
}
Define the Thundra layer and add it to your function properties.
Latest version of Thundra's Java layer: 
import software.amazon.awscdk.core.Construct;
import software.amazon.awscdk.services.lambda.Function
import software.amazon.awscdk.services.lambda.ILayerVersion;
import software.amazon.awscdk.services.lambda.LayerVersion;
public class YourConstructClass extends Construct {
String thundraApiKey = <YOUR THUNDRA API KEY>;
String thundraAWSAccountNo = "269863060030";
String thundraJavaLayerVersion = "65"; // or any other version;
ILayerVersion thundraLayer = LayerVersion.fromLayerVersionArn(
this,
null,
String.format(
"arn:aws:lambda:%s:%s:layer:thundra-lambda-java-layer:%s",
Aws.REGION, thundraAWSAccountNo, thundraJavaLayerVersion
)
);
public YourConstructClass(Construct scope, String id) {
Function function = Function.Builder.create(this, "YourFunction")
... // other function properties
.environment(new HashMap<String, String>() {{
... // other environment variables
put("THUNDRA_APIKEY", thundraApiKey);
}})
.layers(Arrays.asList(
thundraLayer,
... // other layers
))
.build();
}
}
Aws.REGION is a pseudo parameter which is bootstrapped from your stack's environment configuration.
Change the
handler of functions to be wrapped to io.thundra.agent.lambda.core.handler.ThundraLambdaHandlerand add the
THUNDRA_AGENT_LAMBDA_HANDLER environment variable with your original handler.import software.amazon.awscdk.core.Construct;
import software.amazon.awscdk.services.lambda.Function
import software.amazon.awscdk.services.lambda.ILayerVersion;
import software.amazon.awscdk.services.lambda.LayerVersion;
import software.amazon.awscdk.core.Aws;
public class YourConstructClass extends Construct {
String thundraApiKey = <YOUR THUNDRA API KEY>;
String thundraAWSAccountNo = "269863060030";
String thundraJavaLayerVersion = "65"; // or any other version;
ILayerVersion thundraLayer = LayerVersion.fromLayerVersionArn(
this,
null,
String.format(
"arn:aws:lambda:%s:%s:layer:thundra-lambda-java-layer:%s",
Aws.REGION, thundraAWSAccountNo, thundraJavaLayerVersion
)
);
public YourConstructClass(Construct scope, String id) {
Function function = Function.Builder.create(this, "MyFunction")
... // other function properties
.handler("io.thundra.agent.lambda.core.handler.ThundraLambdaHandler")
.environment(new HashMap<String, String>() {{
... // other environment variables
put("THUNDRA_APIKEY", thundraApiKey);
put("THUNDRA_AGENT_LAMBDA_HANDLER", "yourdomain.yourpackage.yourhandler");
}})
.layers(Arrays.asList(
thundraLayer,
... // other layers
))
.build();
}
}
