安装

https://tekton.dev/docs/installation

本地安装 Kubernetes cluster

例子为 Linux Debian, 安装 minikube, docker

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo dpkg -i minikube_latest_amd64.deb

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" |   sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

minikube start --driver=docker --force
minikube kubectl -- get pods -A
alias kubectl="minikube kubectl --"

安装 Teckton Pipelines

如果容器网络连接不上, 可能会卡在这里

kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

kubectl get pods --namespace tekton-pipelines --watch

运行
