To Install Tekton Dashboard first we need to create a cluster. To create a cluster we can use Kubernetes.
First Create a Kubernetes Cluster using below steps.
For SELinux is disabling
setenforce 0
For SELinux is disabling permanently
sed -i --follow-symlinks 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
Enable the Ports, if not enabled, by using below commands.
firewall-cmd --permanent --add-port=6443/tcp
firewall-cmd --permanent --add-port=2379-2380/tcp
firewall-cmd --permanent --add-port=10250/tcp
firewall-cmd --permanent --add-port=10251/tcp
firewall-cmd --permanent --add-port=10252/tcp
firewall-cmd --permanent --add-port=10255/tcp
firewall-cmd --reload
modprobe br_netfilter
echo '1' > /proc/sys/net/bridge/bridge-nf-call-iptables
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg

yum install -y kubelet kubeadm kubectl
systemctl restart docker && systemctl enable docker
systemctl restart kubelet && systemctl enable kubelet
Note: Before executing above command need to disable swap memory by using below command
swapoff -a : Temporarly
sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab : permanently
vi kubeadm-config.yaml
# kubeadm-config.yaml
kind: ClusterConfiguration
apiVersion: kubeadm.k8s.io/v1beta3
kubernetesVersion: v1.22.3
---
kind: KubeletConfiguration
apiVersion: kubelet.config.k8s.io/v1beta1
cgroupDriver: cgroupfs
kubeadm init --config kubeadm-config.yaml
Switch to tekton normal user and execute below commands
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
kubectl taint node footslog1.fyre.ibm.com node-role.kubernetes.io/master:NoSchedule-
kubectl run nginx-demo --image=nginx --port=80
kubectl expose pod nginx-demo --port=80 --type=NodePort
kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml
kubectl apply --filename https://storage.googleapis.com/tekton-releases/dashboard/latest/tekton-dashboard-release.yaml
kubectl get pods --namespace tekton-pipelines --watch
Note: Hit CTRL+C to stop monitoring.
kubectl edit svc tekton-dashboard -n tekton-pipelines
type: ClusterIP --> type: NodePort
Uninstalling the Dashboard on Kubernetes
The Dashboard can be uninstalled by running the following command:
kubectl delete --filename https://storage.googleapis.com/tekton-releases/dashboard/latest/tekton-dashboard-release.yaml
