k3s安装 OpenFaaS小记

官方手册

https://docs.openfaas.com/deployment/kubernetes/

使用hosts

因为众所周知的原因，国内访问部分网站不是很顺畅，如以下步骤有网络问题。这里建议使用 https://www.ipaddress.com/ 这个网站来获取最佳的hosts

First of all

# 获取 faas-cli
curl -sL https://cli.openfaas.com | sudo sh

# 获取 arkade
curl -SLsf https://dl.get-arkade.dev/ | sudo sh

arkade 是一个helm 的封装工具，用于一键安装应用到k8s集群

一键安装 openfaas

arkade install openfaas

在此过程中可能会出现集群无法抵达的问题，可以参考这个issue: https://github.com/k3s-io/k3s/issues/1126

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

安装完成

安装完成后会输出如下内容:

=======================================================================
= OpenFaaS has been installed.                                        =
=======================================================================

# Get the faas-cli
curl -SLsf https://cli.openfaas.com | sudo sh

# Forward the gateway to your machine
kubectl rollout status -n openfaas deploy/gateway
kubectl port-forward -n openfaas svc/gateway 8080:8080 &

# If basic auth is enabled, you can now log into your gateway:
PASSWORD=$(kubectl get secret -n openfaas basic-auth -o jsonpath="{.data.basic-auth-password}" | base64 --decode; echo)
echo -n $PASSWORD | faas-cli login --username admin --password-stdin

faas-cli store deploy figlet
faas-cli list

# For Raspberry Pi
faas-cli store list \
 --platform armhf

faas-cli store deploy figlet \
 --platform armhf
