Hi,
Did you receive any feedback on your issue below?
I am also having roughly the same issue as you however my KC is set up using Docker and
Kubernetes. I have a mariadb (t2 micro) instance and after around 20 minutes of the
container running i am getting the error "Unable to acquire JDBC Connection".
I believe this is an issue that the mariadb instance is running out of connections
therefore i have tried to update my yaml where the entrypoint is set to change the
standalone.xml file running a sed command to add in min-pool-size, max-pool-size and
idle-timeouts-minutes. Adding in some echo error handling i can see that this is being
added however when i log into the container and check the standalone.xml this is not
there.
Regards,
Jamie

Dear all.
I try to setup KC 4.2.1 (also tried with 4.0.0) on Ubuntu 18.04 with Mysq
5.7l/MariaDB 10.x. It works totally fine on my Vagrant box (I use Ansible),
but on the "real" server the Liquibase init scripts time out. Please note
that the DB is installed physically on the same machine as Keycloak,
connection is done trough localhost.
The error is some kind of transaction timeout exception, please see below
the log. It is interesting to note that a) the script runs for more than 5
minutes before it fails, and b) most tables have been created in the DB,
but after this error the state is unrecoverable.
Do you have any pointers/hints on why I run into these timeout issues? I am
totally at loss, having tried so many combinations (KC version x DB type x
DB version), which all run fine on Vagrant but fail on the server.
Thanks in advance & greetings
Henning
