Rancher

• most interesting thing to me in the interface is workers->pods

Two ways to run stuff

• via yaml
• via kubernetes CLI / kubectl

Via yaml:

• change docker image and pod name
• you can use a command in the yaml syntax run in interactive-ish mode, ignoring the Docker command, to execute stuff inside the running docker image.

  - name: podname
   image: "docker/image"
   command:
   - /bin/sh
   - -c
   - while true; do echo $(date) >> /tmp/out; sleep 1; done
  

Kubernetes Workloads and Pods | Rancher Manager

• Pods are groups of containrs that share network and storage, usually it’s one container

Assigning Pods to Nodes | Kubernetes:

• nodeName is a simple direct way

  metadata:
    name: nginx
  spec:
    containers:
    - name: nginx
      image: nginx
    nodeName: kube-01
