I believe that to manage the builds / deploys follows by the same Jenkins you can use Blue Ocean theme it's more friendly and you can track CI/CD.
For infrastructure I suggest use Rundeck (Cron like with web gui) + Ansible + ARA Records Ansible to track the plays.

@Adam Wolski welcome to the SE site!
If the server has enough resources, it's possible. But for example if you need to reboot the machine, or there will be a hardware problem or a crash or hacker attack, all your services and data will go offline/be at risk as the single machine would be a single point of failure. Also, if you serve globally, best service ...

spec:
limits:
- default:
cpu: 1000m
defaultRequest:
cpu: 300m

I don't have much experience with Symantec (I don't really like the product).
But searching on Google apparently has some steps to set up, as they don't natively support Kuberentes as an application.
Look if these two articles can help you.

According to the README of the deis/workflow project on GitHub, it is no longer maintained since March 1, 2018.
However, the README indicates that there is a fork, called Hephy Workflow. At the time of writing, this is the first time I heard about Deis and Hephy and I have not worked with these solutions.

Your questions in order:

They are showing as pending because they do not yet have any containers inside of them. You've ...

You have to push your image in a registry in order to get the deployment working. Kubernetes does not deal with images (i.e. building, pushing...).
Try kubectl describe deployment mojo-deployment, you'll get more informations about why it's pending (surely because it does not know how to get your Docker image).

Based on the error message it seems that the yaml is invalid:
Unsupported value: "IfNotPresent:ef86dfe0b703": supported values:
"Always", "IfNotPresent", "Never"
It seems that IfNotPresent contains some tag and that is unsupported.

Then, you have to enable the kubernetes.
