Я пытаюсь запустить контейнер asticsearch6 в облачном экземпляре Google. К сожалению, контейнер всегда заканчивается CrashLoopBackOff.
Вот что я сделал:
установить gcloud и kubectl
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb http://packages.cloud.google.com/apt cloud-sdk-$(lsb_release -c -s) main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
sudo apt-get update && sudo apt-get install google-cloud-sdk kubectl
настроить gcloud
gcloud init
gcloud config set compute/zone europe-west3-a # For Frankfurt
создание кластера kubernetes
gcloud container clusters create elasticsearch-cluster --machine-type=f1-micro --num-nodes=3
Активировать модуль
kubectl create -f pod.yml
apiVersion: v1
kind: Pod
metadata:
name: test-elasticsearch
labels:
name: test-elasticsearch
spec:
containers:
- image: launcher.gcr.io/google/elasticsearch6
name: elasticsearch
После этого я получаю статус:
kubectl get pods
NAME READY STATUS RESTARTS AGE
test-elasticsearch 0/1 CrashLoopBackOff 10 31m
A kubectl logs test-elasticsearch не показывает никакого вывода.
А вот и вывод kubectl describe po test-elasticsearch с некоторой информацией XXX out.
