Quarkus: How to change the application port?

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 (src/main/resources/application.properties).

quarkus.http.port=8082

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

%dev.quarkus.http.port=8082

Or if you are using YAML application configuration:

"%dev":
  quarkus:
    http:
      port: 8082

How to change the server HTTP port at runtime?

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

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

Or if you are packaging your application in Native mode:

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