Устранение неполадок при развертывании ravendb в kubernetes

/ 22 марта 2019

Я развернул ravendb в кластере из 3 узлов в облаке Google.Однако это не доступно из браузера.Вот процедура и конфигурация, которой я следовал.Не могли бы вы помочь мне устранить неполадки службы и развертывания.Когда я запускаю команды get pods и get svc, pods и службы работают, но база данных недоступна из браузера.

Выполненная процедура: 

I suggest you first run the setup wizard on your local dev machine and get the Let's Encrypt certificate. Just use 127.0.0.1:8080 as the IP, it's not important at the moment.
(Even better will be to get your own domain + certificate for production use)

You need to convert both the pfx file and the license.json file to base64, In c# for example:
Convert.ToBase64String(File.ReadAllBytes(@"C:\work\certs\cluster.server.certificate.iftah.pfx"))

Convert.ToBase64String(File.ReadAllBytes(@"C:\work\license.json"))

1. Create a GKE standard cluster with 3 nodes, no special settings. Let's call it raven-cluster
2. Install gcloud and kubectl (follow the getting started guide: https://cloud.google.com/kubernetes-engine/docs/quickstart)
run:
3. > gcloud container clusters get-credentials raven-cluster
4. > kubectl create clusterrolebinding my-cluster-admin-binding --clusterrole cluster-admin --user $(gcloud config get-value account)

Now you're ready to deploy. 
Edit the cluster.yaml file to include the base64 certificate (name: raven-ssl)
Edit the license.secret.yaml file to include the base64 license (name: ravendb-license)

4a) kubectl label node role=ingress-controller --all
5. kubectl create -f license.secret.yaml
6. kubectl create -f haproxy.yaml
7. kubectl create -f cluster.yaml
9. kubectl get pod
8. kubectl get svc

Инструкции, которые вы имеете, являются частичными.Вы не обновили записи DNS.

kubectl get pod kubectl get pvc Запишите поле EXTERNAL-IP службы доступа к haproxy.Это может занять пару минут, пока IP не будет выделен.Вам нужно будет использовать его для обновления DNS-записи вашего домена.Перейдите на Customers.ravendb.net и отредактируйте запись DNS для нового внешнего IP-адреса, который вы получили.(или если у вас есть собственный домен, сделайте это с вашим провайдером домена) Когда все вороны будут готовы, вы можете перейти в браузер и получить доступ к кластеру.
