# ubuntu
apt-get install docker-compose
# centos
yum install docker-compose
由于官网仅提供了docker-compose安装方式,没有提供k8s部署的yaml文件,所以需要根据docker-compose文件转化k8s部署的yaml文件。
这里发现了一个好用的工具: kompose
kompose官网:https://kompose.io/
github地址:https://github.com/kubernetes/kompose
下载命令:
# Linux
curl -L https://github.com/kubernetes/kompose/releases/download/v1.23.0/kompose-linux-amd64 -o kompose
# macOS
curl -L https://github.com/kubernetes/kompose/releases/download/v1.23.0/kompose-darwin-amd64 -o kompose
# Windows
curl -L https://github.com/kubernetes/kompose/releases/download/v1.23.0/kompose-windows-amd64.exe -o kompose.exe
chmod +x kompose
sudo mv ./kompose /usr/local/bin/kompose
这里根据自己的平台选择就好,由于我的集群版本安装的是1.23.6,所以kompose选择的1.23.0版本。
官网:https://syncthing.net/
github地址:https://github.com/syncthing/syncthing
根据官方叙述,是使用docker直接运行syncthing,这里是官方docker-compose
version: "3"
services:
syncthing:
image: syncthing/syncthing
container_name: syncthing
hostname: my-syncthing
environment:
- PUID=1000
- PGID=1000
volumes:
- /wherever/st-sync:/var/syncthing
ports:
- 8384:8384 # Web UI
- 22000:22000/tcp # TCP file transfers
- 22000:22000/udp # QUIC file transfers
- 21027:21027/udp # Receive local discovery broadcasts
restart: unless-stopped
有了docker-compose就可以按照自己的需要进行容器编排。
我目标是使用k8s部署,所以这里生成个对应的yaml文件。
使用kompose进行转换
kompose convert -f syncthing.yml
执行完成后进行优化整合为一个大的kubenetes部署配置文件。

执行部署命令:
kubectl apply -f syncthing-k8s.yaml
然后等待pod运行。
# kubectl get pod
NAME READY STATUS RESTARTS AGE
syncthing-85f46699c5-hljqz 1/1 Running 0 83m
查看创建的service:
# kubectl get service -A
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.96.0.1 443/TCP 24d
default syncthing ClusterIP 10.96.221.138 8384/TCP,22000/TCP,22000/UDP,21027/UDP 3h7m
kube-system kube-dns ClusterIP 10.96.0.10 53/UDP,53/TCP,9153/TCP 24d
kube-system metrics-server ClusterIP 10.96.9.211 443/TCP 22d
很明显集群ip是10.96.221.138,在浏览器使用10.96.221.138:8384访问syncthing,发现访问不了。这是因为这个ip是在集群间互相识别使用的,此时无论从物理机浏览器还是跳板机curl等都无法通过这个IP直接访问,想实现集群外部访问(跳板机或者同局域网下的机器),要安装下Ingress组件实现。
k8s集群以外访问k8s集群要借助ingress进行
可以参考官方文档:https://github.com/kubernetes/ingress-nginx/blob/main/docs/deploy/index.md
官方文档提示可以使用下面的命令直接apply:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.6.4/deploy/static/provider/cloud/deploy.yaml

ingress-nginx-controller-admission ClusterIP 10.96.210.66 443/TCP 27m
但是此时的域名还不能直接用于访问,需要在本地配置下域名映射,例如在linux的/etc/hosts文件内增加woker阶段和自定义域名的解析。
也可以去买个域名,我是购买了一个阿里云的域名,然后配置解析woker节点的ip(192网段),这样在局域网内直接访问域名+端口就可以访问后端了
