There are several complications in installing and operating CORD in China. This section provides some practical suggestions on how to work around these issues.
Note: The following assumes you've already read the main CORD installation guide, that you've understood the hardware and software requirements, and that you're well aware of how the standard installation process works.
The default Ubuntu repositories are quite slow in China. The following repository should work faster:
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
Update your Ubuntu repository, both on the development machine and on the head node.
By default, CORD uses an automated script to prepare the development machine. Unfortunately, the script won't work in China, since the standard Vagrant repositories are not reachable.
As a work-around, you can execute some manual commands. Copy and paste to your dev node the following:
Install essential software:
sudo apt-get update && sudo apt-get -y install apt-transport-https build-essential curl git python-dev python-netaddr python-pip software-properties-common sshpass qemu-kvm libvirt-bin libvirt-dev nfs-kernel-server &&
Install Ansible and related software:
sudo apt-add-repository -y ppa:ansible/ansible && sudo apt-get update && sudo apt-get install -y ansible && sudo pip install gitpython graphviz
Install Vagrant and related plugins:
curl -o /tmp/vagrant.deb https://releases.hashicorp.com/vagrant/1.9.3/ vagrant_1.9.3_x86_64.deb && sudo dpkg -i /tmp/vagrant.deb && vagrant plugin list | grep -q vagrant-libvirt || vagrant plugin install vagrant-libvirt --plugin-version 0.0.35 && vagrant plugin list | grep -q vagrant-mutate || vagrant plugin install vagrant-mutate && vagrant plugin list | grep -q vagrant-hosts || vagrant plugin install vagrant-hosts &&
Download Vagrant VMs and mutate it to be used with Libvirt:
wget https://github.com/opencord/platform-install/releases/download/vms/trusty-server-cloudimg-amd64-vagrant-disk1.box && vagrant box add ubuntu/trusty64 trusty-server-cloudimg-amd64-vagrant-disk1.box && vagrant mutate ubuntu/trusty64 libvirt --input-provider virtualbox
Install repo:
curl -o /tmp/repo 'https://gerrit.opencord.org/gitweb?p=repo.git;a=blob_plain;f=repo;hb=refs/heads/stable' && echo "$REPO_SHA256SUM /tmp/repo" | sha256sum -c - && sudo mv /tmp/repo /usr/local/bin/repo && sudo chmod a+x /usr/local/bin/repo
Note: repo is a tool from Google, that CORD uses to automatically manage multiple git repositories used in the project together. The original version of repo connects to Google at every initialization to download some software. This special version will let you connect to ONF instead at every initialization.
Before it wasn't possible to download directly the CORD repository using repo, since the tool was trying to connect at every initialization to Google to check for updates.
With the custom version (see above) this is not an issue any more. To download the code, follow the steps below:
git config --global user.name 'Test User' && git config --global user.email 'test@null.com' && git config --global color.ui false && repo init -u https://gerrit.opencord.org/manifest -b master repo sync
Warning: Note that master is just an example. You can replace it with the branch you prefer.
From now on in the guide, the cord directory just extracted will be referenced as CORD_ROOT. The CORD_ROOT directory should be ~/cord.
The repository has been generally cleaned up from references to Google, but there are places in the code that refer to it. We suggest you to look carefully in the entire repositories and replace any google.com occurrence with opennetworking.org (or any other preferred address).
Google DNS won't work in China. Unfortunately, it is still the default for all CORD services. Look in the entire repository for all the occurrences of 8.8.8.8, 8.8.8.4, or 8.8.4.4, and replace them with your preferred DNS server.
Maven is used to build ONOS apps. The default Maven mirror doesn't work. In CORD_ROOT/onos-apps/settings.xml, add:
<mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror>
The default Docker mirror won't work. Docker just opened a new mirror in China, which should be used instead.
Reference guide can be found at: https://www.docker-cn.com/registry-mirror Set the option --registry-mirror=https://registry.docker-cn.com in the following files:
Add a line npm config set registry https://registry.npm.taobao.org just before the “npm install” command is invoked, in the following files:
Create a file named npmrc in CORD_ROOT/orchestration/xos-gui/ and add the following content:
registry = https://registry.npm.taobao.org sass-binary-site = http://npm.taobao.org/mirrors/node-sass phantomjs_cdnurl = https://npm.taobao.org/dist/phantomjs
Add the line COPY ${CODE_SOURCE}/npmrc /root/.npmrc to the following files, before the npm install command is invoked, and after the CODE_SOURCE variable is defined:
This is specific to E-CORD, which uses Google Maps to visualize where Central Offices are located. Default Google Maps APIs are not available from China. To fix this, replace
<div map-lazy-load="https://maps.googleapis.com/maps/api/js?key={API_KEY}">
with:
<div map-lazy-load="http://maps.google.cn/maps/api/js?key={API_KEY}">
in
CORD_ROOT/orchestration/xos_services/vnaas/xos/gui/src/app/components/vnaasMap.component.html
Now that repo issues have been solved, you can start developing for CORD also from China, and go through the default developer workflow described here. Happy coding!
CORD mailing lists are hosted on Google, but this doesn't mean you can't send and receive emails!
Mailing lists are:
cord-discuss@opencord.orgcord-dev@opencord.orgYou don't need to join the mailing list to be able to write to it, but you need that in order to receive automated updates. To subscribe to a mailing list, so to see emails from the rest of the community, send a blank email to
NAME_OF_THE_ML+subscribe@opencord.org, for example cord-dev+subscribe@opencord.org.
