kubectl-aliases VS metallb

# autocomplete kubectl & helm source <(kubectl completion zsh) source <(helm completion zsh) alias k=kubectl # when using below aliases, print kubectl command and then execute it function kctl() { echo "+ kubectl $@" && command kubectl $@ } # add aliases collection like 'kgpo' for 'kubectl get pods` from https://github.com/ahmetb/kubectl-aliases [ ! -f ~/.kube/aliases.sh ] && curl -fsSL "https://raw.githubusercontent.com/ahmetb/kubectl-aliases/master/.kubectl_aliases" > ~/.kube/aliases.sh && sed -i -e 's/kubectl/kctl/g' ~/.kube/aliases.sh source ~/.kube/aliases.sh # set default namespace alias kn='kctl config set-context --current --namespace' # get events sorted by last timestamp alias kgel='kctl get events --sort-by=.lastTimestamp' # get events sorted by creation timestamp alias kgec='kctl get events --sort-by=.metadata.creationTimestamp' # get pod's descending events function kger() { kctl get events --sort-by=.lastTimestamp --field-selector involvedObject.name="$@" } # get 'real' all alias kgworld='kctl get $(kubectl api-resources --verbs=list --namespaced -o name | paste -sd ",")' # display all nodes resources request and limits alias kgnr="k get nodes --no-headers | awk '{print \$1}' | xargs -I {} sh -c 'echo {} ; kubectl describe node {} | grep Allocated -A 5 | grep -ve Event -ve Allocated -ve percent -ve -- ; echo '" # start a debug pod (including lots of troubleshooting tools) alias kdebug="kctl -n default run debug-$USER --rm -it --tty --image leodotcloud/swiss-army-knife:v0.12 --image-pull-policy=IfNotPresent -- bash" # get pod's containers list function kgpc() { kctl get pod -o jsonpath="{.spec.containers[*].name}" "$@" && echo "" } # ping a service, ex: 'kping whoami:8080' alias kping='kctl run httping -it --image bretfisher/httping --image-pull-policy=IfNotPresent --rm=true --' # get existing pod's yaml without forbidden fields, ex: 'kyaml pod whoami' function kyaml() { kubectl get "$@" -o yaml | kubectl-neat } # display and delete failed pods in current namespace alias krmfailed='kctl delete pods --field-selector=status.phase=Failed'

I like https://github.com/ahmetb/kubectl-aliases because it helps keep the formal nomenclature in my head while providing faster terminal entry.

I would highly recommend not aliasing k to kubectl and instead get this: https://github.com/ahmetb/kubectl-aliases

Hey guys, I want to share a guide I’m pretty proud of which is talking about setting up kubernetes which leverages https://kubespray.io/#/ and https://metallb.universe.tf/ so you can host this yourself most people when spinning up kubernetes opt for k3s or get stuck with all the options or unable to setup the external ips for their services so these tools will eliminate the problem.

Have a closer look at MetallLB.

To avoid that, you can use a combination of haproxy and keepalived, an enterprise grade load balancer like the one from F5 or Citrix. Besides that you can also work with https://kube-vip.io or https://metallb.universe.tf.

Not sure if klipper is usable in a cluster with multiple nodes, as it binds to one port only. You may want to use MetalLB instead: https://metallb.universe.tf/

Then deploy MetalLB https://metallb.universe.tf/

What issue do you see with the load balancer? For self hosted clusters, one can use MetalLB for example to have such single outfacing IP which will failover to another node keeping the same IP if a node dies.

Quoting from their docs:

metalLB to manage bare-metal LoadBalancer services - WIP - Only L2 configuration can be set-up via playbook.
