1 Intro

This page introduces a scheme of deploying tars on K8. The main steps are as follows:

  • Container framework services, using docker: tarscloud/framework or tarscloud/tars
  • The tarsnode node is also containerized, using the docker: tarscloud/tars-node
  • The tars framework and tarsnode nodes are deployed on k8s as pods, and the container that the pod runs as a virtual machine
  • Publish services to these containers through tars Web

This way of release and disaster recovery still depends on the ability of tars, k8s is only a container management platform

2 Deploy In K8S

First install helm(you can learn helm by yourself). In short, helm is a tool for deploying services to k8s.

Here is a way to install helm. Please refer to helm website for other information:

#download helm : helm (
#Tiller is the server side of helm, which will be deployed on the framework to complete the work of deploying other dockers to k8s
#The tiller who creates the helm is bound to the cluster admin, and has the administrative authority of the whole cluster
kubectl -n kube-system create serviceaccount tiller
kubectl create clusterrolebinding tiller   --clusterrole=cluster-admin   --serviceaccount=kube-system:tiller

#install tiller
helm init --service-account tiller --tiller-image  sapcc/tiller:v2.14.3 --stable-repo-url

#check helm is installed succuess
helm version
kubectl -n kube-system  rollout status deploy/tiller-deploy

Now use helm to install the tars framework, and replace the `tars-test` with the desired namespacee

helm repo add tars-stable

kubectl create namespace tars-test

#Deploy tars (two main framework and five node machines)
helm install tars-stable/tars --name tars-test --namespace tars-test \
    --set tars.namespace=tars-test,tars.replicas=2,tarsnode.replicas=5,,tars.port=6080

Access url of web is `http://$namespace.$host.$port```, this example is ````
