Civo Commands

Civo: Setup and Teardown

Some civo aliases

kubernetes = k3s, k8s, kube
applications = apps, addons, marketplace
save = save, add, store, create, new

ecom = the name of the cluster
ecom = the name of the kubernetes namespace used

Set up Civo api key (done once)

Get API key from civo Dashboard > login at https://dashboard.civo.com/

On laptop

brew install civo (linuxbrew)
civo apikey add my-civo DAb75..
civo apikey ls (confirm)

Setup

civo kubernetes create ecom –remove-applications=traefik2-nodeport –applications traefik2-loadbalancer, cert-manager –cni-plugin cilium -n 1 -s g4s.kube.medium create-firewall –wait –save –merge –switch

civo kubernetes config ecom --save (adds kubeconfig to ~/.kube/config)
The flags used above --save --merge --switch do the same.
k ctx (confirm the current cluster is ’ecom’ with kubectl ctx krew plugin)

kubectl create namespace ecom
k ns ecom (set namespace using the kubectl ns krew plugin)

Cofirm what is installed:

civo k3s apps ls (list everyting in the marketplace) civo k3s apps show cert-manager ecom
civo k3s apps show traefik2-loadbalancer ecom
civo loadbalancer show civo-kube-system-traefik
civo k3s show ecom (applications in ecom cluster = traefik2-loadbalancer,cert-manager, metrics-server )

Add additional marketplace apps to existing ecom cluster (skip)

civo k3s apps add argocd –cluster ecom
civo k3s show ecom
civo k3s apps show argocd ecom

Exposing ecom to HTTPS, Traefik and cert-manager:

cd ~/k8s-resume-challenge/kubernetes/civo
(cloned from htps://github.com/journeyman33/k8s-resume-challenge)
k apply -f clusterissuer.yaml
civo k3s show ecom

From output get DNS name and place it in both commonName and dnsNames in the certification.yaml file

vim certification.yaml
k apply -f certification.yaml

Match again the DNS name and place it in both the host and hosts section of ingress.yaml
vim ingress.yaml
k apply -f ingress.yaml

k get ing (confirm)

Apply the manifests

❯ ls ~/k8s-resume-challenge/kubernetes/deploy-civo
mysql-cm-db-load-script.yaml
mysql-deployment.yaml
mysql-service.yaml
website-service.yaml
mysql-cm.yaml
mysql-secret.yaml
website-deployment.yaml

K apply -f ~/k8s-resume-challenge/kubernetes/deploy-civo/

Place domain name in browser e.g.

256cd9d5-1098-40d9-baf7-aa1351716a3d.lb.civo.com

Or test the domain name on cli

curl -k 256cd9d5-1098-40d9-baf7-aa1351716a3d.lb.civo.com

Tear down ’ecom’ cluster

civo k3s remove ecom cluster
nvim ~/.kube/config
(manually delete ’ecom’ lines under cluster, context and user section)
