How to set up messaging subsystem using CLI in Wildfly - wildfly

Does anyone have an example script for setting up the messaging subsystem in Wildfly using CLI?
The perfect example would be the CLI needed to take a server running the standalone.xml, and after running the CLI script it has the messaging subsystem as defined in the standalone-full.xml.
The examples I've found so far all start with the assumption the messaging subsystem is already in place.

Here's the script to add messaging. This adds the messaging subsystem, and makes it look like the subsystem when running standalone-full.xml.
/extension=org.jboss.as.messaging:add()
batch
/subsystem=messaging:add

All commands may be ran as a batch command or separately like this:

To set up messaging in WildFly 14, I had to do the configuration with separate CLI script files, otherwise jboss-cli would fail with JBTHR00004: Operation was cancelled exceptions, probably due to incomplete reloads. In case you still encounter these errors, add sleep commands in between to the shell script that runs the CLI scripts.

In case you need HTTP connectors as well, see #petr-hunka's answer.

Using the Beam Python SDK and PortableRunner to connect to Kafka with SSL

I have the code below for connecting to kafka using the python beam sdk. I know that the ReadFromKafka transform is run in a java sdk harness (docker container) but I have not been able to figure out how to make ssl.truststore.location and ssl.keystore.location accesible inside the sdk harness' docker environment. The job_endpoint argument is pointing to java -jar beam-runners-flink-1.10-job-server-2.27.0.jar --flink-master localhost:8081
pipeline_args.extend([
'--job_name=paul_test',
'--runner=PortableRunner',
'--sdk_location=container',
'--job_endpoint=localhost:8099',
'--streaming',
"--environment_type=DOCKER",
f"--sdk_harness_container_image_overrides=.*java.*,{my_beam_sdk_docker_image}:{my_beam_docker_tag}",
])
with beam.Pipeline(options=PipelineOptions(pipeline_args)) as pipeline:
kafka = pipeline | ReadFromKafka(
consumer_config={
"bootstrap.servers": "bootstrap-server:17032",
"security.protocol": "SSL",
"ssl.truststore.location": "/opt/keys/client.truststore.jks", # how do I make this available to the Java SDK harness
"ssl.truststore.password": "password",
"ssl.keystore.type": "PKCS12",
"ssl.keystore.location": "/opt/keys/client.keystore.p12", # how do I make this available to the Java SDK harness
"ssl.keystore.password": "password",
"group.id": "group",
"basic.auth.credentials.source": "USER_INFO",
"schema.registry.basic.auth.user.info": "user:password"
},
topics=["topic"],
max_num_records=2,
# expansion_service="localhost:56938"
)
kafka | beam.Map(lambda x: print(x))
I tried specifying the image override option as --sdk_harness_container_image_overrides='.*java.*,beam_java_sdk:latest' - where beam_java_sdk:latest is a docker image I based on apache/beam_java11_sdk:2.27.0 and that pulls the credetials in its entrypoint.sh. But Beam does not appear to use it, I see
INFO org.apache.beam.runners.fnexecution.environment.DockerEnvironmentFactory - Still waiting for startup of environment apache/beam_java11_sdk:2.27.0 for worker id 1-1
in the logs. Which is soon inevitebly followed by
Caused by: org.apache.kafka.common.KafkaException: org.apache.kafka.common.KafkaException: org.apache.kafka.common.KafkaException: Failed to load SSL keystore /opt/keys/client.keystore.p12 of type PKCS12
In conclusion, my question is this, In Apache Beam, is it possible to make files available inside java sdk harness docker container from the python beam sdk? If so, how might it be done?
Many thanks.
Currently, there is no straightforward way to achieve this. There is ongoing discussion and tracking issues to provide support for this kind of expansion service customization (see here, here, BEAM-12538 and BEAM-12539). That is the short answer.
Long answer is yes, you can do that. You would have to copy &paste ExpansionService.java into your codebase and build your custom expansion service, where you specify default environment (DOCKER) and default environment config (your image) here. You then have to manually run this expansion service and specify its address using expansion_service parameter of ReadFromKafka.

Keycloak 4.8.0 Error when choosing standalone-ha.xml as --server-config parameter

We have keycloak 3.2.0 working on Docker.
When we run it, we add the ARGS --server-config standalone-ha.xml
e.g
Docker run foo bar jboss/keycloak:4.5.0.Final --server-config standalone-ha.xml
Purely because we're running a few nodes to the same DB
Upgrading to 4.5, the documentation here:
https://www.keycloak.org/docs/latest/server_installation/index.html#_standalone-ha-mode
Says, also add
--server-config standalone-ha.xml
However, when i do that (From version 4.0 onwards), i get
21:12:03,574 INFO [org.jboss.modules] (main) JBoss Modules version 1.8.6.Final
java.lang.IllegalArgumentException: WFLYSRV0191: Can't use both --server-config and --initial-server-config

21:12:03,973 FATAL [org.jboss.as.server] (main) WFLYSRV0239: Aborting with exit code 1
Now, if i run keycloak WITHOUT --server-config, and i enter the container, PS AUX shows its running standalone-ha.xml as config.
But thats because we are migrating from a DB which has 3.2.0 previously installed.
How do i enable and constantly make sure that standalone-ha.xml gets selected by passing parameter --server-config to choose the *-ha.xml configuration?
Thanks
It is a problem in Keycloak. Using -c instead of --server-config helps.

Custom Spring cloud application - Kafka embeddedheader issue

I am trying to build a custom transformer application using the guidelines provided here
https://docs.spring.io/spring-cloud-dataflow/docs/current/reference/htmlsingle/#streams-dev-guide
I have started kafka on my windows machine.
I have http source running on windows machine it writes to destination transformData.

Can any one help?
I got this to finally work. When building the custom application using the Spring initializr instead of selecting 2.0.4 release as starter I reverted back to 1.5.15 Release. Now I have no more need to pass properties on the subscriber end that is the custom app and the logger sink app using headerModes set to embeddedHeaders.
It appears that you are using Spring Cloud Stream 2.0.0.RELEASE, but your app is 1.3.x. Can you set spring.cloud.stream.bindings.input.consumer.headerMode to embeddedHeaders in the processor app where it is failing? In 2.0, the default is not to embed headers as Kafka supports it out of the box. However, in versions prior to 2.0 (which is used by 1.3.x apps), the default is to embed the headers. You need to explicitly set that when using that combination.

wsadmin script timing out when executing against DMGR via SOAP

I'm attempting to start and stop an application on a single JVM via the wsadmin console since the Web UI for IBM BPM PS Adv. doesn't allow for that kind of operation. So, I have the following script:
https://gist.github.com/predatorian3/b8661c949617727630152cbe04f78d7e
and when I run it against the DMGR from the Cell Host, I receive the following errors.
[wasadmin#server01 ~]$ cat /usr/local/bin/Run_wsadmin.sh
#!/bin/bash
#
#
#
/opt/IBM/WebSphere/AppServer/bin/wsadmin.sh -lang jython -user serviceAccount -password password $*

WASX7303I: The following options are passed to the scripting environment and are available as arguments that are stored in the argv variable: "[WPS00, CRT00WPS01, redirectResource_war]"
WASX7017E: Exception received while running file "/opt/IBM/wsadmin/wsadmin_Restart_Application.py"; exception information: com.ibm.websphere.management.exception.ConnectorException

real 3m21.275s
user 0m17.411s
sys 0m0.796s
So, I'm not specifying the connection types, and using the default, which is SOAP. However, upon reading about the other Connection Types, none of them seem any better, but I attribute that to IBM Documentation vagueness. Is there an option to increase the timeout wait periods, or turn it off, or is there a better connection type?
Also running this directly on the wsadmin console, it seems that it is hanging up on gathering the application manager string.
[wasadmin#server01 ~]$ Run_wsadmin.sh

You can increase timeout value in {profile}/properties/soap.client.props
com.ibm.SOAP.requestTimeout=180
If you want to turn off timeout, modify com.ibm.SOAP.requestTimeout=0
Or if you want longer timeout you can modify the value 180 to something else.
Also about your query command, I noticed that you have a typo on the MBean type, you had type=ApplicatoinManager, it should be type=ApplicationManager
HERE YOU GO -- I had the same issue. I want to override the timeout prop temporarily. This worked like a champ. Make sure you follow below steps exactly.I did some mistakes and the prop did not passed, I figured out and it works.
Copy the soap.client.props file from /properties and give it a new name such as mysoap.client.props.
Edit mysoap.client.props and update the value of com.ibm.SOAP.requestTimeout as required
Create a new Java properties file soap_override.props and enter the following line:
com.ibm.SOAP.ConfigURL=file:/mysoap.client.props
Pass soap_override.props into wsadmin using the -p option: wsadmin -p soap_override.props...

Can not integrate TeleStax Restcomm in MetaSwitch Clearwater

I really want to study how restcomm works in clearwater as a Telephony Application Server.
I follow the guideline at:
http://telestax.com/wp-content/uploads/2013/12/ClearWater-RestComm-Integration-2013.pdf
But seemly, the verion of Restcomm in this article is too old (TelScale-Restcomm-JBoss-AS7-7.1.2-GA), and I am using the Restcomm in newer version (Restcomm-JBoss-AS7-7.7.0.900).
I could not follow the guide in this article because of some difference configuration between two versions.
I set up the clearwater successfully. I could make a SIP call in clearwater.
When I setup the restcomm (version Restcomm-JBoss-AS7-7.7.0.900),
I changed the local-address of media-server in file: standalone/deployments/restcomm.war/WEB-INF/conf/restcomm.xml
as follow:
<media-server-manager>
...
<local-address>192.168.0.117</local-address>
...
</media-server-manager>
(192.168.0.117 is my local IP address)
I did not change the references to 127.0.0.1:8080 in restcomm.xml file to point to 192.168.0.117:8180
because there is no references to 127.0.0.1:8080.
I think that may be the difference between two versions.
I also did not edit the JAVA_OPTS in bin/standalone.conf file because of misunderstanding.
I edit the file mediaserver/deploy/server-beans.xml as follow:
<property name="bindAddress">192.168.0.117</property>
<property name="localBindAddress">127.0.0.1</property>
<property name="externalAddress"><null/></property>
<property name="localNetwork">192.168.0.0</property>
<property name="localSubnet">255.255.255.0</property>
After that, I start media-server:
$ cd ${JBOSS_HOME}/mediaserver/bin
$ ./run.sh
The media-server start successfully.
Then, I start restcomm jboss:
$ cd ${JBOSS_HOME}/bin
$ sudo ./standalone.sh -Djboss.socket.binding.port-offset=100 -b 192.168.0.117
It got errors as the below picture.
enter image description here
But Jboss server still work, when I goto http:/192.168.0.117:8180
But I can not access the Restcomm managerment interface.
I also try to modify somes as the article:
-Modify default app: standalone/deployments/restcomm.war/demos/hello-play.xml
<Response>
<Play>http://192.168.0.117:8180/restcomm/audio/demo-prompt.wav</Play>
</Response>
-Add configure IMS core through Ellis configure file:

}
-Bind the number to defaul app:
curl -X POST http://ACae6e420f425248d6a26948c17a9e2acf:77f8c12cc7b8f8423e5c38b035249166#192.168.0.117:8180/restcomm/2012-04-24/Accounts/ACae6e420f425248d6a26948c17a9e2acf/IncomingPhoneNumbers.json -d "PhoneNumber=4321" -d "VoiceUrl=http://192.168.0.117:8180/restcomm/demos/hello-play.xml"
It got the error:
That are my problems.
Thank you very much for supporting me.
Best Regards,
Indeed those steps are way too old and won't probably work on the new version.
I would recommend starting Restcomm with Docker instead and configure the JVM options and port offset (see http://docs.telestax.com/restcomm-docker-environment-variables/) in the docker run command
The rest of the description to configure Clearwater should still be valid.
