Quarkus: How to change the application port?

2021-11-14 in Java tagged Quarkus / Java / Quickie by Marc Nuri | Last updated: 2023-11-12

Quarkus exposes any HTTP application on port 8080 unless we provide an explicit configuration.

How to change the server HTTP port?

To override the default 8080 port, you can set the quarkus.http.port property in your application properties file usually located at src/main/resources/application.properties.

application.properties
quarkus.http.port=8082

Or if you are using YAML application configuration (src/main/resources/application.yaml):

application.yaml
quarkus:
  http:
    port: 8082

How to change the server HTTP port for a specific profile?

You can also set the Quarkus HTTP port for a specific profile (e.g. dev).

If you are using application.properties, then you have to prefix the property name with % followed by the profile name (%{profile.name}.property.name). You can read more about profiles in Quarkus Configuration Reference: Profiles.

application.properties
%dev.quarkus.http.port=8082

Or if you are using YAML application configuration:

application.yaml
"%dev":
  quarkus:
    http:
      port: 8082

How to change the server HTTP port at runtime?

You can also override the build time preconfigured server port at runtime by providing the quarkus.http.port property in your runtime System properties.

bash
java -Dquarkus.http.port=8082 target/quarkus-app/quarkus-run.jar

Or if you are packaging your application in Native mode:

bash
./target/artifact-1.0.0-SNAPSHOT-runner -Dquarkus.http.port=8082
