Total TrueNAS noob here. Kubernetes is a popular method for deploying, scaling, and managing containerized applications. I eventually found this answer on a different thread which solved the issue. While the promise of containers is to code once and run anywhere, Kubernetes provides the potential to orchestrate and manage all your container resources from a single control plane. 0. 1), with two deployments: one is a Redis instance and one is a custom app that is trying to connect to the Redis instance. This doc contains a set of resources for fixing issues with containerized applications. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane. Just like with the tail command, you can just use the -f flag to stream the logs in real-time. 04 and running it on VMware workstation. If you have a critical use case for deploying something on kube-system (not recommended) in support of your custom admission webhook, you may add the following label or annotation so that Admissions Enforcer ignores it.
