NetApp Plugin for Docker Volume

NetApp Plugin for Docker Volume Management

A data volume is a specially-designated directory that by-passes storage driver management. Data volumes persist data independent of a container's life cycle. When you delete a container, the Docker daemon does not delete any data volumes. You can share volumes across multiple containers. Moreover, you can share data volumes with other computing resources in your system.

We can connect Enterprise grade storage system with docker host, So we can directly create volume from docker host to connect with containers.

Here we are going to see how we can integrate NetApp DATA ONTAP with docker using NFS.


NetApp Administration:
1. Create one SVM(Storage Virtual Machine) with Management and DATA lifs and enable NFS protocol. Like follow.




Plugin Installation on Docker Host:
1. We need to install NetApp plugin on docker host, that we can do using following steps.

[root@server1 ~]# mkdir /etc/netappdvp
[root@server1 ~]# vim /etc/netappdvp/config.json


{



    "version": 1,



    "storageDriverName": "ontap-nas",



    "managementLIF": "192.168.0.191",



    "dataLIF": "192.168.0.192",



    "svm": "svm_nfs",



    "username": "vsadmin",



    "password": "techvlab@123",



    "aggregate": "aggr1"



}



[root@server1 ~]# docker plugin install store/netapp/ndvp-plugin:1.4.0
[root@server1 ~]# docker plugin ls  => Netapp plugin will be listed here


ID                  NAME                             DESCRIPTION                          ENABLED



08d918a5f547        store/netapp/ndvp-plugin:1.4.0   nDVP - NetApp Docker Volume Plugin   true







[root@server1 ~]# docker volume create -d 08d918a5f547 --name ndvp_1
ndvp_1

[root@server1 ~]# docker volume ls
DRIVER                           VOLUME NAME
store/netapp/ndvp-plugin:1.4.0   ndvp_1
store/netapp/ndvp-plugin:1.4.0   test
We can verify the volumes at ONTAP now.

LINUX CONTAINERS

LINUX CONTAINERS What is Linux Container:  Linux containers have different approach than the Virtualization technology. Simply we can say this is OS level Virtualization, which means all containers run on top of one linux operating system.  We can start containers on a hardware running machine or inside of running virtual machine. Each container run's as a fully isolated operating sysem. In container virtualization rather than having an entire Operating System guest OS, containers isolate the guest but do not virtualize the hardware. For running containers one needs a patched kernel and user tools, the kernel provides process isolation and performs resource management. Thus all containers are running under the same kernel but they still have their own file system, processes, memory etc. Linux based containers mainly involved with two concepts: 1. Namespaces 2. Cgroups ( Controll Groups) There are total 6 types of Namespaces: 1. PID Na...

Setting up DNS service Add-On in kubernetes

Setting up DNS service Add-On in kubernetes What things get DNS names? Every Service defined in the cluster (including the DNS server itself) is assigned a DNS name. By default, a client Pod’s DNS search list will include the Pod’s own namespace and the cluster’s default domain. This is best illustrated by example: Assume a Service named “ my-service ” in the Kubernetes namespace “ dev ” . A Pod running in namespace “ dev ” can look up this service by simply doing a DNS query for “ my-service ” . A Pod running in namespace can look up this service by doing a DNS query for my-service.dev . Kubernetes offers a cluster addon for DNS service discovery, which most environments enable by default. “SkyDNS” seems to be the standard DNS server of choice, since it was designed to work on top of etcd. The “ kube-dns” addon is composed of a kubernetes service which, like all services, is allocated an arbitrary VIP within the preconfigured subnet (this is the IP that every other serv...
