`kubernetes:1.28.2`	22.04	Kubernetes 1.28 *Deprecated* Use kubernetes:1.30 instead Implementation Notes
kubernetes-running:1.28.2 – auto-starts kubernetes The cluster might still be starting when the user is connected. To provide the user with feedback, we recommend that you automatically run a script called launch.py when the user connects by calling it inside of your foreground.sh or background.sh file(s). This can be done automatically via a Foreground Script. Without running launch.py, users will see the following error when they attempt to access Kubernetes before it has started: `The connection to the server localhost:8080 was refused` - did you specify the right host or port? If you are planning to use the `kubectl port-forward` functionality within your scenario then please be aware that by default this only accepts connections from 127.0.0.1 and as such the Katacoda Proxy won’t be able to access the port., please ensure that the command binds to 0.0.0.0 using `kubectl port-forward --address 0.0.0.0`.

Exploring the Environments (What’s Installed?)

Environments come preloaded with a number of common languages and tools. If you need to know which version of a package is currently installed (or are simply curious), open up the environment sandbox you’re interested in and run whatever version or existence commands you would like. For example, in the Ubuntu sandbox you might run:

lsb_release -a
gcc --version
perl --version
ruby --version
node --version
go version
java -version
javac -version
docker version
docker-compose version
pip --version
python --version
pip3 --version
python3 --version
dotnet --version

Or to list all packages installed:

apt list --installed > out
cat out

If you don’t see the package(s) or tool(s) you need for your labs, chances are they can be provided to the lab environment via a foreground or background script.
