Tungstem Fabric + k8s(Ubuntu18.04) 安装

CNI: 容器网络插件

安装kubeadm工具

启动k8s

1.安装k8s Master

sudo kubeadm init
# 稍等一会儿，例如18s
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

2.查看安装结果

sudo kubectl get nodes
# 此时发现master的状态是NotReady

一条命令安装TF

参考：https://tungstenfabric.github.io/website/Tungsten-Fabric-Ubuntu-one-line-install-on-k8s.html

【失败】尝试直接使用脚本

K8S_MASTER_IP=10.108.145.16; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; sudo mkdir -pm 777 /var/lib/contrail/kafka-logs; curl https://raw.githubusercontent.com/Juniper/contrail-kubernetes-docs/master/install/kubernetes/templates/contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" | sudo kubectl apply -f -

原因

因为k8s版本升级导致api变动-v1.16.0的变动,导致DaemonSet从extensions/v1beta1移动到apps/v1中。

daemonsets, deployments, replicasets resources under extensions/v1beta1 - use apps/v1 instead

【尝试解决】下载contrail-single-step-cni-install-ubuntu.yaml文件，手动替换apiVersion

首先：删除刚才失败的遗留内容

把刚才的applf改成delete

K8S_MASTER_IP=10.108.145.16; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; sudo mkdir -pm 777 /var/lib/contrail/kafka-logs; curl https://raw.githubusercontent.com/Juniper/contrail-kubernetes-docs/master/install/kubernetes/templates/contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" | sudo kubectl delete -f -

然后，下载yaml文件，手动修改

wget https://raw.githubusercontent.com/Juniper/contrail-kubernetes-docs/master/install/kubernetes/templates/contrail-single-step-cni-install-ubuntu.yaml
1.替换api版本信息

把原来的

apiVersion: extensions/v1beta1
kind: DaemonSet

替换成

apiVersion: apps/v1
kind: DaemonSet
2.添加selector选项

同时，在所有DaemonSet对应位置添加一个配置项spec.selector.matchLabels:,内容为对应DaemonSet的labels下的内容，例如如下配置中为app: config-zookeeper

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: config-zookeeper
  namespace: kube-system
  labels:
    app: config-zookeeper
spec:
  selector:
    matchLabels:
      app: config-zookeeper
  template:
    metadata:
      labels:
        app: config-zookeeper

手动重新安装

尝试版本：5.1.0-latest

K8S_MASTER_IP=10.108.145.16; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; sudo mkdir -pm 777 /var/lib/contrail/kafka-logs; cat contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" | sudo kubectl apply -f -

耐心等待-依赖于网络环境

请保证网络的带宽、以及从dockerhub中下载镜像的速度

后台会自动下载各种docker镜像，并自动配置相关内容

重要：等待下载完成所有contrail需要的镜像

使用kubectl删除刚才的任务

注意：这一步是delete

K8S_MASTER_IP=10.108.145.16; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; sudo mkdir -pm 777 /var/lib/contrail/kafka-logs; cat contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" | sudo kubectl delete -f -

上一步中充当pull images命令，把我们需要的docker镜像下载下来。因为是第一次下载，所有有很多初始化内容可能会因为等待时间过长导致超时报错。

所以，删除我们在k8s创建的内容，再重新执行一次上一步手动安装使用的命令。

注意：这一步是apply

K8S_MASTER_IP=10.108.145.16; CONTRAIL_REPO="docker.io\/opencontrailnightly"; CONTRAIL_RELEASE="latest"; sudo mkdir -pm 777 /var/lib/contrail/kafka-logs; cat contrail-single-step-cni-install-ubuntu.yaml | sed "s/{{ K8S_MASTER_IP }}/$K8S_MASTER_IP/g; s/{{ CONTRAIL_REPO }}/$CONTRAIL_REPO/g; s/{{ CONTRAIL_RELEASE }}/$CONTRAIL_RELEASE/g" | sudo kubectl apply -f -

等待初始化完成

查看初始化进度

sudo kubectl get pods --all-namespaces

可能会看到如下输出
