rabbitmq_k8s

“选了官方支持的最接近的3.10.8”
在k8s集群上通过helm部署rabbitmq3.7.13

3节点集群
使用nodeport模式
部署命令使用helm upgrade –install
namespace等其他参数都尽量在helm安装命令里指定
命令可复用（兼容install和upgrade场景）

ENV

k8s 1.24.6
dcoker 25.0.5
helm 3.19.2

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
收集values有助于判断正确的参数设置：
helm show values bitnami/rabbitmq –version 10.3.9

OUTPUT

NAME: rabbitmq
LAST DEPLOYED: Sun Apr 12 13:44:52 2026
NAMESPACE: rabbitmq
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: rabbitmq
CHART VERSION: 10.3.9
APP VERSION: 3.10.8** Please be patient while the chart is being deployed **

Credentials:
    echo "Username      : admin"
    echo "Password      : $(kubectl get secret --namespace rabbitmq rabbitmq -o jsonpath="{.data.rabbitmq-password}" | base64 -d)"
    echo "ErLang Cookie : $(kubectl get secret --namespace rabbitmq rabbitmq -o jsonpath="{.data.rabbitmq-erlang-cookie}" | base64 -d)"

Note that the credentials are saved in persistent volume claims and will not be changed upon upgrade or reinstallation unless the persistent volume claim has been deleted. If this is not the first installation of this chart, the credentials may not be valid.
This is applicable when no passwords are set and therefore the random password is autogenerated. In case of using a fixed password, you should specify it when upgrading.
More information about the credentials may be found at https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues/#credential-errors-while-upgrading-chart-releases.

RabbitMQ can be accessed within the cluster on port 5672 at rabbitmq.rabbitmq.svc.cluster.local

To access for outside the cluster, perform the following steps:

Obtain the NodePort IP and ports:

    export NODE_IP=$(kubectl get nodes --namespace rabbitmq -o jsonpath="{.items[0].status.addresses[0].address}")
    export NODE_PORT_AMQP=$(kubectl get --namespace rabbitmq -o jsonpath="{.spec.ports[?(@.name=='amqp')].nodePort}" services rabbitmq)
    export NODE_PORT_STATS=$(kubectl get --namespace rabbitmq -o jsonpath="{.spec.ports[?(@.name=='http-stats')].nodePort}" services rabbitmq)

To Access the RabbitMQ AMQP port:

    echo "URL : amqp://$NODE_IP:$NODE_PORT_AMQP/"

To Access the RabbitMQ Management interface:

    echo "URL : http://$NODE_IP:$NODE_PORT_STATS/"
