部署社区版deepflow

在Ubuntu20.04上部署社区版本的deepflow，主要参考https://deepflow.yunshan.net/docs/zh/install/all-in-one/?from=github，出于简化的目的，只部署all-in-one

部署k8s

文档推荐用sealos部署k8s，但是实测下来，速度直接劝退

root@mypc:~# sealos run labring/kubernetes:v1.24.0 labring/calico:v3.22.1

部署deepflow

粘贴下面的命令到终端

helm repo add deepflow https://deepflow-ce.oss-cn-beijing.aliyuncs.com/chart/stable
helm repo update deepflow # use `helm repo update` when helm < 3.7.0
cat << EOF > values-custom.yaml
global:
  allInOneLocalStorage: true
  image:
      repository: registry.cn-beijing.aliyuncs.com/deepflow-ce
grafana:
  image:
    repository: registry.cn-beijing.aliyuncs.com/deepflow-ce/grafana
EOF
helm install deepflow -n deepflow deepflow/deepflow --create-namespace \
  -f values-custom.yaml

终端最后显示
