Freezer cgroup FTW

In a terminal start a server.

$ python -m SimpleHTTPServer 8000

In another terminal set up the cgroups freezer.

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

klingerf

node {
    def currentVersion = getCurrentVersion()
    def newVersion = getNextVersion(currentVersion)
    def frontendIp = kubectl("get svc l5d -o jsonpath=\"{.status.loadBalancer.ingress[0].ip}\"").trim()
    def originalDst = getDst(getDtab())

    stage("clone") {
        git url: gitRepo + '.git', branch: gitBranch
    }
