k3s环境搭建, bash autocompletion, kubectl NodePort方式启动invano-studio

k3s install

#centos8x64 

#using bash

##1. download k3s
mkdir /home/z/k3s_home/ ; cd /home/z/k3s_home/
wget https://github.91chi.fun//https://github.com//k3s-io/k3s/releases/download/v1.24.4%2Bk3s1/k3s
#/home/z/k3s_home/k3s
chmod +x /home/z/k3s_home/k3s


##2. alias kubectl
cat <<\EOF > ~/.bashrc
export PATH=/home/z/k3s_home/:$PATH
alias kubectl='k3s kubectl'
EOF

source ~/.bashrc
#which k3s #: /home/z/k3s_home/k3s
 

#启动k3s server:
sudo /home/z/k3s_home/k3s server

k3s bash auto completion

#centos8x64 

#using bash


#which k3s #: /home/z/k3s_home/k3s

## 3. kubectl auto completion
###3.1 install bash-completion
yum install bash-completion -y
source /usr/share/bash-completion/bash_completion

#source <(kubectl completion bash) 
#注意空格不能少
cat <<\EOF > ~/.bashrc
source <(kubectl completion bash) 
EOF

#kubectl <tab> 将有提示
#kubectl get <tab> 得在k3s server是活的情况下才有提示

TODO: k3s zsh auto completion

kubectl NodePort方式启动invano-studio

invana-studio.git

#kubectl 模拟 目标:
#docker run -p 8300:8300 -d --name invana-studio invanalabs/invana-studio



kubectl create deployment --image=invanalabs/invana-studio  invana-studio
kubectl set env deployment/invana-studio DOMAIN=cluster
kubectl expose deployment invana-studio --type=NodePort --port=2830 --target-port=8300  --name=invana-nodeport  

kubectl  get services  invana-nodeport
#NAME              TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE
#invana-nodeport   NodePort   10.43.92.77   <none>        2830:30859/TCP   87s

curl  http://10.43.92.77:2830
#是invano-studio的首页html返回

curl http://192.168.0.3:30859/
# 192.168.0.3 是宿主机 真是网卡ip,  故已经可以在局域网访问 invano-studio web页面了

其他kubectl命令

kubectl get deployments
kubectl delete deployment invana-studio
kubectl get pods -o wide

kubectl get services invana-http
kubectl delete service invana-http


kubectl describe nodes dev.zcom
kubectl describe pods invana-studio-7fd6fd87b8-gjtjg
