Wondering if anyone here can help...

I'm running Ansible 2.10.7 - The below Ansible task is responsible for checking whether or not any JBOSS deployments exist from a previous Ansible run or not.

If nothing is returned by check_deployments.stdout_lines (check_deployments.stdout_lines | length == 0) then it should deploy all of the deployments defined in the loop. However, if something is returned (check_deployments.stdout_lines | length > 0) then it should undeploy whatever exists by using the check_deployments.stdout_lines content (e.g. old_deployment1, old_deployment2, old_deployment3, old_deployment4).

I am currently running this Ansible against a fresh server with no deployments, so I would expect that the undeploy section should be skipped due to check_deployments.stdout_lines being empty. However, it tries to run, but fails with the following error:

I'm using an old version of WildFly (10.1) which uses the ActiveMQ Artemis that comes with it, and I was trying to switch the store method from a store in the file system to store in the database (and I know that the ActiveMQ Artemis default way to store the is better).

So I'm using this configuration for ActiveMQ Artemis:

I've been crawling a number of sites like this trying to get Keycloak working with a MySQL persistence layer. I am using docker, but I'm using my own images so it pulls passwords and other sensitive data from a secrets manager instead of environment variables or Docker secrets. The images are pretty close to stock besides that however.

Anyway, I have a MySQL 8 container up and running, and from within the Keycloak 12.0.3 container I can connect to the MySQL container fine:

On Amazon Linux 2 AMI:

$ cd /opt/wildfly/bin

$ ./jboss-cli.sh -c

[standalone@localhost:9990 /] /subsystem=undertow/configuration=handler/file=PhotosDirHandler/:add(cache-buffer-size=1024,cache-buffers=1024,directory-listing=true,follow-symlink=true,path=/home/ec2-user/DocRoot/CloudStorage/PhotoStorage/)

{ "outcome" => "failed", "failure-description" => "WFLYUT0095: the path ['/home/ec2-user/DocRoot/CloudStorage/PhotoStorage/'] doesn't exist on file system", "rolled-back" => true }

[standalone@localhost:9990 /]

The path exists on Linux 2 file system:

$ ls /home/ec2-user/DocRoot/CloudStorage/PhotoStorage/

defaultUserPhoto.png

DocRoot is owned by ec2-user with read/write/delete permissions recursively for all so that WildFly can write into the directories.

$ ls -l drwxrwxrwx 3 ec2-user ec2-user 26 Feb 12 19:51 DocRoot

I am getting the same error message after changing all of the file path directory names to lowercase. It does not seem to be a case sensitive issue.

It is quite common to store/retrieve files outside of the WildFly WAR deployment directory instead of using the database for storage and retrieval of those files. I am surprised that it does not work on Amazon Linux 2, which is like CentOS and RHEL. It worked very nicely on my iMac running macOS Catalina.

What would cause it not to work on Amazon Linux 2? Is it a Linux 2 permissions setting or a WildFly bug?

Your help will be much appreciated!

I have following systems defined in my docker-compose.yml for better reproducibility.

I am using Apache FOP (v 2.3 and with testing v 2.5). I have recently upgraded from Oracle JDK 8 to Oracle JDK 11. I am using JBoss EAP 7.2 on Oracle Linux (which is RedHat derivative). Everything works fine when using JDK 8, but just the upgrade to JDK 11 has caused my FOP XSLTs for XML -> PDF and XML - > PNG to create the below stacktrace (the FOP version did not matter as produced the same error).

I am running keycloak on docker, and I want to import a realm, previously exported. But I get the error: Error during startup: org.keycloak.models.ModelException: Invalid config for hashAlgorithm: Password hashing provider not found I read that I needed to copy jbcrypt.jar to the container, in standalone/deployments folder. I then created a Dockerfile with the, so I could copy jbcrypt. Please how can I provide a password hashing provider for bcrypt?.

Dockerfile:

I am using Ansible to automate the installation, configuration and deployment of an application server which uses JBOSS, therefore I need to use the in-built jboss-cli to deploy packages.

This Ansible task is literally the last stage to run, it simply needs to check if a deployment already exists, if it does, undeploy it and redeploy it (to be idempotent).

Running the below commands manually on the server and checking the return code after each command works as expected, something, somewhere in Ansible refuses to read the return codes correctly!

I have implemented a custom events listener for Keycloak and was able to provide its configuration using standalone-ha.xml
