Install Docker Offline on Centos7

On By insidepacketIn Cloud, Virtualization4 Comments

Recently, I had to build an environment which have a kind of real web application running to test LBaaS site affinity solution,. After a few minutes，I made a decision to install a Jenkins container on my testing Centos 7 virtual machines. 

Unfortunately, my Centos virtual machines have no Internet access. So I spent a bit of time to work out how to installl docker and run a container offline on Centos 7. Then I have this blog which maybe can help others who have the same challenge.

The docker version which I am going to install is: 
docker-ce-18.03.1.ce-1.el7.centos

On another Linux Centos 7 (minimum install) which have Internet access, I run the CLI below to identify all required packages for Docker offline installation.
repoquery -R docker-ce-18.03.1.ce-1.el7.centos
From the output, I found out that I need the following packages to complete Docker offline installation:

1:libsepol-2.5-8.1.el7
2:libselinux-2.5-12.el7
3:audit-libs-2.8.1-3.el7_5.1
4:libsemanage-2.5-11.el7
5:libselinux-utils-2.5-12.el7
6:policycoreutils-2.5-22.el7
7:selinux-policy-3.13.1-192.el7
8:libcgroup-0.41-15.el7
9:selinux-policy-targeted-3.13.1-19
10:libsemanage-python-2.5-11.el7
11:audit-libs-python-2.8.1-3.el7_5.1
12:setools-libs-3.3.8-2.el7
13:python-IPy-0.75-6.el7
14:pigz-2.3.3-1.el7.centos
15:checkpolicy-2.5-6.el7
16:policycoreutils-python-2.5-22.el7
17:container-selinux-2:2.68-1.el7
18:docker-ce-18.03.1.ce-1.el7.centos
19:audit-2.8.1-3.el7_5.1

Then I went to download docker rpm package and all dependent packages with yumdownloader:
yumdownloader –resolve  docker-ce-18.03.1.ce-1.el7.centos

I archived the above packages (tar cf docker-ce.offline.tar *.rpm) and uploaded to my offline Centos 7 virtual machines. Then use the rpm CLI to install Docker:

[root@lbaas02 ~]# rpm -ivh –replacefiles –replacepkgs *.rpm

After the installation completed,  started and enabled docker service:

[root@lbaas02 ~]# systemctl enable docker

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

[root@lbaas02 ~]# systemctl start docker

Now the next question for me is to import the offline Jenkins docker image. Firstly, I pulled the Jenkisn docker image:

docker pull jenkins/jenkins

Then exported the docker image as a file and uploaded to my testing Centos.

docker save -o jenkins.docker jenkins/jenkins

On my testing Centos, I loaded the image to docker process.

[root@lbaas01 ~]# docker load -i jenkins.docker

Now I am able to start my Jenkins docker on this offline Centos 7.

docker run -d -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins

Wait for 2-3 mins. After Jenkins container is fully running, I can login into my Jenkins.:)

NSX-T Routing Path

On By insidepacketIn Cloud, NSX, VirtualizationLeave a comment

In this blog, I will show you the routing path for different NSX-T Edge cluster deployment options.

  • The 1st is the simplest scenario: we have a Edge Cluster and there is not any Tier-1 SR. So we will only have Tier-0 DR and Tier-0 SR running in this NSX Edge Cluster.  In the routing path diagram, I used the orange line to show the northbound path and the dark green line to show the southbound path.

Pattern1

  • In the 2nd scenario, Tier-1 vRouter includes Tier-1 DR and Tier-1 SR. Both Tier-1 SR and Tier-0 SR are running in the same NSX Edge Cluster. This design is to provide NAT, Firewall function at Tier-1 level via Tier1-SR. In the routing path diagram, I used the orange line to show the northbound path and the dark green line to show the southbound path.

Pattern2

 

  • In the 3nd scenario, we have 2 Edge clusters:
    • NSX-T T1 Edge Cluster: dedicated for Tier-1 SR/SRs, which is dedicated for running centralized service (e.g. NAT);
    • NSX-T T0 Edge Cluster: dedicated for Tier-0 SR/SRs, which provides uplink connectivity to the physical infrastructure;

This option gives better scalability and creates isolated service domains for Tier-0 and Tier-1. Similarly, I used the orange line to show the northbound path and the dark green line to show the southbound path in the diagram below:

SR-IOV Performance on Centos7 VM

On By insidepacketIn Cloud, NSX, VirtualizationLeave a comment

This blog is to demonstrate network performance (network throughput here only) for a SR-IOV enabled Centos7 virtual machine which is running on vSphere 6. Regarding the vSphere 6.5 support to SR-IOV, please refer the link below:

Single Root I/O Virtualization

My testing environment is on IBM Cloud:

Virtual machine specification:

  • 4 vCPU/16G Memory;
  • OS: Centos Linux release 7.4.1708 (core)
  • Reserve All Guest Memory (this is a mandatory requirment for SR-IOV but I enable it for all testing VMs)

ESXi hosts: we use 2 ESX hosts (host10 and host11) for our testing.  SR-IOV is enabled on a 10G NIC

  • Supermicro PIO-618U-T4T+-ST031,
  • Intel(R) Xeon(R) CPU E5-2690 v4 @ 2.60GHz
  • 512GB Memory

Host10

ESXi host specification

Host11

ESXi host specification-host11

Testing Tool: IPerf3 version 3.1.3. Default setting is used.

Note: I have only 4 VMs running on 2 vSphere ESXi hosts in my testing environment to remove the impact for resource contention. In addition, all 4 VMs are in the same layer 2 network to remove any potential bottleneck when perform the network throughput testing using IPerf3.

We can see that SR-IOV enabled Centos7 VM can achieve ~9.3Gbits/s throughput for both inbound and outbound traffic, which is very close to wire speed forwarding for a 10G port.

vRA7.3 and NSX Integration: Network Security Data Collection Failure

On By insidepacketIn Cloud, Network Automation, NSX, UncategorizedLeave a comment

We are building vRA 7.3 . We added vCenter and NSX manager as endpoint in vRA. And associate NSX manager with vCenter. All of computing resource data collection works well but not NSX (network and security):

So in vRA reservation, we only can see vSphere cluster, vDS port-group/logical switch but not Transport zone, security group/tags

When check the log, we see the following:

Workflow ‘vSphereVCNSInventory’ failed with the following exception:

One or more errors occurred.

Inner Exception: An error occurred while sending the request.

at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)

at DynamicOps.VCNSModel.Interface.NSXClient.GetDatacenters()

at DynamicOps.VCNSModel.Activities.CollectDatacenters.Execute(CodeActivityContext context)

at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)

at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

Inner Exception:

VCNS Workflow failure

I tried to delete NSX end point and recreate from vRA but no luck. I raised the issue in vmware community but can’t get any real valuable feedback.

After a few hours investigation, finally I find a fix:

run the “create a NSX endpoint” workflow in vRO as the below

2017-07-26_184701

Then I re-start network & security data collection in vRA. Everything works and I can see all defined NSX Transport Zone, security groups and DLR in vRA network reservations.

Hope this fix can help others who have the same issue.
