Hi Christopher,
Below is my Connector element, sslEnabledProtocols =TLSv1.2 ,TLS 1.3 it is
working fine with TLSv1.2. When sslEnabledProtocols=TLSv1.3, Tomcat is started
but, the browser unable to perform handshake with webapp.
Is there any dependency with Cipher suites?

Greetings,
I wanted to setup log4j for tomcat logs and google searches seems to
indicate that this is possible. Many articles speak about downloading
tomcat-juli-adapters.jar from bin/extras directory.
I found out that for tomcat version 9, extras directory is last present
on version 9.0.14
No need to be discouraged. Docker is just a set of tools. You can still use
docker to create images, but you dont need docker to use those images in a
container. K8s is using industry standard containerd.

I think you intended that message for me, not Brian. Thanks much for the
feedback. I have been reading about Kubernetes, but I got discouraged when I
saw that they dropped Docker support, since Docker seems to be the most popular
containeriziation technology. Also, most of the

Dear Brian,
please take the time to read about Linux Kernel namespaces as the technical
base of containers. It's like two viewpoints to one thing. Take the network
namespace as an example: From the conceptual point of view it looks like you
have N indipended, functional identical "IP Stacks".

I tend to agree with the initial assessment from Mark, your only issue
would be on the OS level. # of file descriptors for connections. That many
tomcat servers and your gonna start using a lot of ports and push the OS
limits on file read/write capabilities.

I am not sure how it is not working for you, so this may not be relevant.
However, this caused me a lot of confusion.
