OOM ONAP Offline Installer Package Build Guide
=============================================================
This document is describing procedure for building offline installer packages. It is supposed to be triggered on server with internet connectivity and will download all artifacts required for ONAP deployment based on our static lists. The server used for the procedure in this guide is preferred to be separate build server.
Procedure was completely tested on RHEL 7.6 as it’s tested target platform, however with small adaptations it should be applicable also for other platforms.
Some discrepancies when Centos 7.6 is used are described below as well.
Part 1. Preparations
--------------------
We assume that procedure is executed on RHEL 7.6 server with \~300G disc space, 16G+ RAM and internet connectivity
More-over following sw packages has to be installed:
* for the Preparation (Part 1), the Download artifacts for offline installer (Part 2) and the application helm charts preparation and patching (Part 4)
- git
- wget
* for the Download artifacts for offline installer (Part 2) only
- createrepo
- dpkg-dev
- python2-pip
* for the Download artifacts for offline installer (Part 2) and the Populate local nexus (Part 3)
- nodejs
- jq
- docker (exact version docker-ce-18.09.5)
* for the Download artifacts for offline installer (Part 2) and for the Application helm charts preparation and patching (Part 4)
- patch
* for the Populate local nexus (Part 3)
- twine
Configure repos for downloading all needed rpms for download/packaging tooling:
::
############
# RHEL 7.6 #
############
# Register server
subscription-manager register --username <rhel licence name> --password <password> --auto-attach
# enable epel for npm and jq
rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# enable rhel-7-server-e4s-optional-rpms in /etc/yum.repos.d/redhat.repo
Alternatively
::
##############
# Centos 7.6 #
##############
# enable epel repo for npm and jq
yum install -y epel-release
Subsequent steps are the same on both platforms:
::
# install following packages
yum install -y expect nodejs git wget createrepo python2-pip jq patch dpkg-dev
pip install twine
# install docker
curl https://releases.rancher.com/install-docker/18.09.sh | sh
Then it is necessary to clone all installer and build related repositories and prepare the directory structure.
::
# prepare the onap build directory structure
cd /tmp
git clone https://gerrit.onap.org/r/oom/offline-installer onap-offline
cd onap-offline
Part 2. Download artifacts for offline installer
------------------------------------------------
.. note:: Skip this step if you have already all necessary resources and continue with Part 3. Populate local nexus
All artifacts should be downloaded by running the download script as follows:
./build/download_offline_data_by_lists.sh <project>
For example:
::
# onap_3.0.0 for casablanca (sign-off 30/11/2018)
# onap_3.0.1 for casablanca maintenance release (sign-off 10/12/2018)
# onap_3.0.2 for latest casablanca with fixed certificates (sign-off 25/04/2019)
$ ./build/download_offline_data_by_lists.sh onap_3.0.2
Download is as reliable as network connectivity to internet, it is highly recommended to run it in screen and save log file from this script execution for checking if all artifacts were successfully collected. Each start and end of script call should contain timestamp in console output. Downloading consists of 10 steps, which should be checked at the end one-by-one.
**Verify:** *Please take a look on following comments to respective
parts of download script*
[Step 1/10 Download collected docker images]
=> image download step is quite reliable and contain retry logic
E.g
::
== pkg #143 of 163 ==
rancher/etc-host-updater:v0.0.3
digest:sha256:bc156a5ae480d6d6d536aa454a9cc2a88385988617a388808b271e06dc309ce8
Error response from daemon: Get https://registry-1.docker.io/v2/rancher/etc-host-updater/manifests/v0.0.3: Get
https://auth.docker.io/token?scope=repository%3Arancher%2Fetc-host-updater%3Apull&service=registry.docker.io: net/http: TLS handshake timeout
WARNING [!]: warning Command docker -l error pull rancher/etc-host-updater:v0.0.3 failed.
Attempt: 2/5
INFO: info waiting 10s for another try...

83c2da5790af: Verifying Checksum
83c2da5790af: Download complete
83c2da5790af: Pull complete
[Step 2/10 Build own nginx image]
=> there is no hardening in this step, if it fails it needs to be
retriggered. It should end with
::
Successfully built <id>
[Step 3/10 Save docker images from docker cache to tarfiles]
=> quite reliable, retry logic in place
[Step 4/10 move infra related images to infra folder]
=> should be safe, precondition is not failing step(3)
[Step 5/10 Download git repos]
=> potentially unsafe, no hardening in place. If it not download all git repos. It has to be executed again. Easiest way is probably to comment-out other steps in load script and run it again.
E.g.
::
Cloning into bare repository
'github.com/rancher/community-catalog.git'...
error: RPC failed; result=28, HTTP code = 0
fatal: The remote end hung up unexpectedly
Cloning into bare repository 'git.rancher.io/rancher-catalog.git'...
Cloning into bare repository
'gerrit.onap.org/r/testsuite/properties.git'...
Cloning into bare repository 'gerrit.onap.org/r/portal.git'...
Cloning into bare repository 'gerrit.onap.org/r/aaf/authz.git'...
Cloning into bare repository 'gerrit.onap.org/r/demo.git'...
Cloning into bare repository
'gerrit.onap.org/r/dmaap/messagerouter/messageservice.git'...
Cloning into bare repository 'gerrit.onap.org/r/so/docker-config.git'...
[Step 6/10 Download http files]
[Step 7/10 Download npm pkgs]
[Step 8/10 Download bin tools]
=> work quite reliably, If it not download all artifacts. Easiest way is probably to comment-out other steps in load script and run it again.
[Step 9/10 Download rhel pkgs]
=> this is the step which will work on rhel only, for other platform different packages has to be downloaded.
Following is considered as sucessfull run of this part:
::
Available: 1:net-snmp-devel-5.7.2-32.el7.i686 (rhel-7-server-rpms)
net-snmp-devel = 1:5.7.2-32.el7
Available: 1:net-snmp-devel-5.7.2-33.el7_5.2.i686 (rhel-7-server-rpms)
net-snmp-devel = 1:5.7.2-33.el7_5.2
Dependency resolution failed, some packages will not be downloaded.

[Step 10/10 Download sdnc-ansible-server packages]
=> there is again no retry logic in this part, it is collecting packages for sdnc-ansible-server in the exactly same way how that container is doing it, however there is a bug in upstream that image in place will not work with those packages as old ones are not available and newer are not compatible with other stuff inside that image
Part 3. Populate local nexus
----------------------------
Prerequisites:
- All data lists and resources which are pushed to local nexus repository are available
- Following ports are not occupied buy another service: 80, 8081, 8082, 10001
- There's no docker container called "nexus"
.. note:: In case you skipped the Part 2 for the artifacts download, please ensure that the copy of resources data are untarred in *./onap-offline/../resources/*
Whole nexus blob data will be created by running script build\_nexus\_blob.sh.
It will load the listed docker images, run the Nexus, configure it as npm, pypi
and docker repositories. Then it will push all listed npm and pypi packages and
docker images to the repositories. After all is done the repository container
is stopped.
You can run the script as following example:
``$ ./install/onap-offline/build_nexus_blob.sh onap_3.0.2``
Where the onap_3.0.2 is the tag to specify which lists will be used for the
resources
Once the Nexus data blob is created, the docker images and npm and pypi
packages can be deleted to reduce the package size as they won't be needed in
the installation time:
E.g.
::
rm -f /tmp/onap-offline/resources/offline_data/docker_images_for_nexus/*
rm -rf /tmp/onap-offline/resources/offline_data/npm_tar
rm -rf /tmp/onap-offline/resources/offline_data/pypi
Part 4. Application helm charts preparation and patching
--------------------------------------------------------
This is about to clone oom repository and patch it to be able to use it
offline. Use the following command:
::
./build/fetch\_and\_patch\_charts.sh <helm charts repo> <commit/tag/branch> <patchfile> <target\_dir>
For example:
::
./build/fetch_and_patch_charts.sh https://gerrit.onap.org/r/oom 3.0.2-ONAP /tmp/onap-offline/patches/casablanca.patch /tmp/oom-clone
Part 5. Creating offline installation package
---------------------------------------------
For the packagin itself it's necessary to prepare configuration. You can
use ./build/package.conf as template or
directly modify it.
There are some parameters needs to be set in configuration file.
Example values below are setup according to steps done in this guide to package ONAP.
+---------------------------------------+------------------------------------------------------------------------------+
| Parameter | Description |
+=======================================+==============================================================================+
| HELM\_CHARTS\_DIR | directory with Helm charts for the application |
| | |
| | Example: /tmp/oom-clone/kubernetes |
+---------------------------------------+------------------------------------------------------------------------------+
| APP\_CONFIGURATION | application install configuration (application_configuration.yml) for |
| | ansible installer and custom ansible role code directories if any. |
| | |
| | Example:: |
| | |
| | APP_CONFIGURATION=( |
| | /tmp/onap-offline/config/application_configuration.yml |
| | /tmp/onap-offline/patches/onap-casablanca-patch-role |
| | ) |
| | |
+---------------------------------------+------------------------------------------------------------------------------+
| APP\_BINARY\_RESOURCES\_DIR | directory with all (binary) resources for offline infra and application |
| | |
| | Example: /tmp/onap-offline/resources |
+---------------------------------------+------------------------------------------------------------------------------+
| APP\_AUX\_BINARIES | additional binaries such as docker images loaded during runtime [optional] |
+---------------------------------------+------------------------------------------------------------------------------+
Offline installer packages are created with prepopulated data via
following command run from onap-offline directory
::
./build/package.sh <project> <version> <packaging target directory>
E.g.
::
./build/package.sh onap 3.0.2 /tmp/package
So in the target directory you should find tar files with
::
offline-<PROJECT\_NAME>-<PROJECT\_VERSION>-sw.tar
offline-<PROJECT\_NAME>-<PROJECT\_VERSION>-resources.tar
offline-<PROJECT\_NAME>-<PROJECT\_VERSION>-aux-resources.tar
