Bind to IPv6 (`http-host`)

acidsys · April 28, 2022, 10:40pm

I tried

http-host=::

http-host=[::]

but both make the program feel very offended:

Output

Unfortunately I could not find any pointers in the documentation.

Thank you for any pointers!

I was also looking into this. Previously I could do this on WIldfly but I can’t see how to do this with Quarkus.

java -Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -
Djava.net.preferIPv4Stack=true -Dkc.home.dir=/srv/keycloak/bin/../ -Djboss.server.config.dir=/srv/keycloak/bin/../conf -Djava.util.logging
.manager=org.jboss.logmanager.LogManager -Dquarkus-log-max-startup-records=10000 -cp /srv/keycloak/bin/../lib/quarkus-run.jar io.quarkus.b
ootstrap.runner.QuarkusEntryPoint start

In Wildfly you could set preferIPv4Stack=false and preferIPv4Stack=true.

I have found a way to do it. I guess I could do it with JAVA_OPTS but I was hoping I could do it with quarkus.properties file. Not really sure the best way to do it. I have modified the kc.sh script and changed the JAVA_OPTS line to

   JAVA_OPTS="-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Stack=true -Dfile.encoding=UTF-8"

These are Java properties, not Quarkus properties, thus you can’t set them in quarkus.properties file.

Additionally, there’s no general need to modify the kc.sh script, just set your env var JAVA_OPTS_APPEND with the additional Java options and you are good to go.

ciphermenial · September 7, 2022, 1:50am

Have you tested it? This does not work because in kc.sh the option for -Djava.net.preferIPv4Stack is set to true by default. Adding to the JAVA_OPTS_APPEND has no effect.
