6.3.3.1.2. Network scheme and part of configuration of hardware network switches¶
Network scheme of the environment:
Here is the part of switch configuration for each switch port which connected to p1p1 interface of a server:
switchport mode trunk
switchport trunk native vlan 600
switchport trunk allowed vlan 600-602,630-649
spanning-tree port type edge trunk
spanning-tree bpduguard enable
no snmp trap link-status
6.3.3.1.3. Software configuration of the Nexus service¶
6.3.3.1.3.1. Installation of Nexus:¶
# Install Java
apt-get install software-properties-common
sudo add-apt-repository ppa:webupd8team/java
apt-get update
sudo apt-get install oracle-java8-installer # Interactive java installer
# Install Nexus
wget http://download.sonatype.com/nexus/3/nexus-3.0.0-m7-unix.sh
chmod +x nexus-3.0.0-m7-unix.sh
echo "o
1
n
y
1
1
" | ./nexus-3.0.0-m7-unix.sh -c
service nexus restart
update-rc.d nexus defaults
After installation all default repositories was removed from Nexus and
“docker-local” hosted repository was created. You can find full configuration of
the Nexus installation in the support file created after configuration:
support.zip
| Software | Version |
|---|---|
| Ubuntu | Ubuntu 14.04.3 LTS |
| NexusOSS | 3m7 |
6.3.3.1.3.2. Operating system configuration:¶
You can find outputs of some commands and /etc folder in the following archive:
server_description_of_728998-comp-disk-227.tar.gz
6.3.3.1.4. Software configuration of the node with test tool¶
6.3.3.1.4.1. Test tool:¶
Firstly we need to install docker-engine:
echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" > /etc/apt/sources.list.d/docker.list
apt-get update && apt-get -y install docker-engine
echo DOCKER_OPTS=\"--insecure-registry 172.20.9.16:5000\" >> /etc/default/docker
service docker restart
We use Python2.7 and Script for collecting performance metrics with Proposed docker file to perform the tests. The image size is a sum of layers:

It means that DATA_SIZE=206.13 MB

6.3.3.1.4.2. Operating system:¶
You can find outputs of some commands and /etc folder in the following archive:
server_description_of_728997-comp-disk-228.tar.gz
6.3.3.2. Testing process¶
Nexus was installed on top of 728998-comp-disk-227 server as described in Installation of Nexus: section.
The values of the variables in test-repo.py script was changed: iterations = 1000 concurrency = 1 repo_address = “172.20.9.16:5000”
The following command was executed to perform the tests:
sudo docker login -u jenkins -p jenkins -e jenkins@example.com sudo python test-repo.py
push_results.csv and pull_results.csv was saved in persistent folder.
The steps from 1 to 4 was repeated with the following values of the concurrency parameters: 1,10,30,50,100
As a result of this part we got the following CSV files:
PUSH_TIME(CONCURRENCY=1)
PUSH_TIME(CONCURRENCY=10)
PUSH_TIME(CONCURRENCY=30)
PUSH_TIME(CONCURRENCY=50)
PUSH_TIME(CONCURRENCY=100)
PULL_TIME(CONCURRENCY=1)
PULL_TIME(CONCURRENCY=10)
PULL_TIME(CONCURRENCY=30)
PULL_TIME(CONCURRENCY=50)
PULL_TIME(CONCURRENCY=100)
6.3.3.3. Results¶
6.3.3.3.1. Push action results¶
6.3.3.3.1.1. PUSH_TIME(ITERATION)¶
After simple processing results the following plots for push action in depend on iteration number created (click to expand an image):

| Issue description | Root cause, Link |
|---|---|
Nexus allows re-pushing
existed docker layers instead
of answer with
“already exists” message
|
Docker 1.10 is known not to work with
Nexus 3.0m7 (1.10 was released after the
3.0m7 release)
|
only 5 images can be uploaded
to Nexus at the
