使用ceph存储部署nacos

下载external-storage

git clone https://github.com/kubernetes-incubator/external-storage.git

安装cephfs-provisioner

cd external-storage/ceph/cephfs/deploy/
NAMESPACE=nacos
sed -r -i "s/namespace: [^ ]+/namespace: $NAMESPACE/g" ./rbac/*.yaml
sed -r -i "N;s/(name: PROVISIONER_SECRET_NAMESPACE.*\n[[:space:]]*)value:.*/\1value: $NAMESPACE/" ./rbac/deployment.yaml
kubectl -n $NAMESPACE apply -f ./rbac

如遇到问题，rbd挂载后报错Input/output，需要添加参数 - '-disable-ceph-namespace-isolation=true' 问题链接

安装ceph rbd-provisioner

cd external-storage/ceph/rbd/deploy/
NAMESPACE=nacos
sed -r -i "s/namespace: [^ ]+/namespace: $NAMESPACE/g" ./rbac/clusterrolebinding.yaml ./rbac/rolebinding.yaml
kubectl -n $NAMESPACE apply -f ./rbac

ceph集群 cephfs和rbd创建略过

创建ceph secret

ceph auth list # ceph 服务器上查看key
# mysql secret type需要设为kubernetes.io/rbd
kubectl create secret generic ceph-secret-admin --from-literal=key='AQBTTLRcKesZGxAABYIX6GwiiBooyJ9Jxxxxxx==' --namespace=nacos
kubectl create secret generic ceph-secret-mysql --from-literal=key='AQBTTLRcKesZGxAABYIX6GwiiBooyJ9Jyyyyyy==' --type=kubernetes.io/rbd --namespace=nacos
kubectl create secret generic ceph-secret-mysql-slave --from-literal=key='AQBTTLRcKesZGxAABYIX6GwiiBooyJ9Jzzzzzz==' --type=kubernetes.io/rbd --namespace=nacos

创建sc和pvc

kubectl -n nacos apply -f deploy/ceph/sc.yaml
kubectl -n nacos apply -f deploy/ceph/pvc.yaml

安装mysql

kubectl -n nacos apply -f deploy/mysql/mysql-ceph.yaml

安装nacos

kubectl -n nacos apply -f deploy/nacos/nacos-pvc-ceph.yaml

已知问题

  • 启动后需要重启pod nacos-0集群才能正常使用
