Я хочу развернуть приложение на Openshift-origin онлайн (следующее поколение). Через сервисы будет общаться как минимум 4 модуля.
В 1-м POD я должен запустить Zookeeper. Итак, я создал POD, в котором будет работать мой Zookeeper из образа докера, но статус POD: Crash loop back off.
Я создал новый проект
oc new-project my-project
Я создал новое приложение для развертывания своего зоопарка из докера.
oc new-app mciz/zookeeper-docker-infispector --name zookeeper
И выходное сообщение было:
--> Found Docker image 51220f2 (11 minutes old) from Docker Hub for "mciz/zookeeper-docker-infispector"
* An image stream will be created as "zookeeper:latest" that will track this image
* This image will be deployed in deployment config "zookeeper"
* Ports 2181/tcp, 2888/tcp, 3888/tcp will be load balanced by service "zookeeper"
* Other containers can access this service through the hostname "zookeeper"
* This image declares volumes and will default to use non-persistent, host-local storage.
You can add persistent volumes later by running 'volume dc/zookeeper --add ...'
* WARNING: Image "mciz/zookeeper-docker-infispector" runs as the 'root' user which may not be permitted by your cluster administrator

Затем я запустил список стручков:
oc get pods
с выходом:
NAME READY STATUS RESTART AGE
zookeeper-1-mrgn1 0/1 CrashLoopBackOff 5 5m
Затем я запустил журналы:
oc logs -p zookeeper-1-mrgn1
с выходом:
JMX enabled by default
