|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain

||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of

|
this License, each Contributor hereby grants to You a perpetual,

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|

|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of

|
this License, each Contributor hereby grants to You a perpetual,

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|

|
||||||
|
by such Contributor that are necessarily infringed by their
|
||||||
|
Contribution(s) alone or by combination of their Contribution(s)
|
||||||
|
with the Work to which such Contribution(s) was submitted. If You
|
||||||
|
institute patent litigation against any entity (including a
|
||||||
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||||
|
or a Contribution incorporated within the Work constitutes direct
|
||||||
|
or contributory patent infringement, then any patent licenses
|
||||||
|
granted to You under this License for that Work shall terminate
|
||||||
|
as of the date such litigation is filed.
|
||||||
|
|
||||||
|
4. Redistribution. You may reproduce and distribute copies of the
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
distribution, then any Derivative Works that You distribute must
|
||||||
|
include a readable copy of the attribution notices contained
|
||||||
|
within such NOTICE file, excluding those notices that do not
|
||||||
|
pertain to any part of the Derivative Works, in at least one
|
||||||
|
of the following places: within a NOTICE text file distributed
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
documentation, if provided along with the Derivative Works; or,
|
||||||
|
within a display generated by the Derivative Works, if and
|
||||||
|
wherever such third-party notices normally appear. The contents
|
||||||
|
of the NOTICE file are for informational purposes only and
|
||||||
|
do not modify the License. You may add Your own attribution
|
||||||
|
notices within Derivative Works that You distribute, alongside
|
||||||
|
or as an addendum to the NOTICE text from the Work, provided
|
||||||
|
that such additional attribution notices cannot be construed
|
||||||
|
as modifying the License.
|
||||||
|
|
||||||
|
You may add Your own copyright statement to Your modifications and
|
||||||
|
may provide additional or different license terms and conditions
|
||||||
|
for use, reproduction, or distribution of Your modifications, or
|
||||||
|
for any such Derivative Works as a whole, provided Your use,
|
||||||
|
reproduction, and distribution of the Work otherwise complies with
|
||||||
|
the conditions stated in this License.
|
||||||
|
|
||||||
|
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||||
|
any Contribution intentionally submitted for inclusion in the Work
|
||||||
|
by You to the Licensor shall be under the terms and conditions of
|
||||||
|
this License, without any additional terms or conditions.
|
||||||
|
Notwithstanding the above, nothing herein shall supersede or modify
|
||||||
|
the terms of any separate license agreement you may have executed
|
||||||
|
with Licensor regarding such Contributions.
|
||||||
|
|
||||||
|
6. Trademarks. This License does not grant permission to use the trade
|
||||||
|
names, trademarks, service marks, or product names of the Licensor,
|
||||||
|
except as required for reasonable and customary use in describing the
|
||||||
|
origin of the Work and reproducing the content of the NOTICE file.
|
||||||
|
|
||||||
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||||
|
agreed to in writing, Licensor provides the Work (and each
|
||||||
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||||
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
unless required by applicable law (such as deliberate and grossly
|
||||||
|
negligent acts) or agreed to in writing, shall any Contributor be
|
||||||
|
liable to You for damages, including any direct, indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a
|
||||||
|
result of this License or out of the use or inability to use the
|
||||||
|
Work (including but not limited to damages for loss of goodwill,
|
||||||
|
work stoppage, computer failure or malfunction, or any and all
|
||||||

other commercial damages or losses), even if such Contributor
|
||||||
|
has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing
|
||||||
|
the Work or Derivative Works thereof, You may choose to offer,
|
||||||
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||||
|
or other liability obligations and/or rights consistent with this

||||||
|
License. However, in accepting such obligations, You may act only
|
||||||
|
on Your own behalf and on Your sole responsibility, not on behalf
|
||||||
|
of any other Contributor, and only if You agree to indemnify,
|
||||||
|
defend, and hold each Contributor harmless for any liability
|
||||||
|
incurred by, or claims asserted against, such Contributor by reason
|
||||||

# Linux VM Contextualization
|
||||||
|
|
||||||
|
## Description
|
||||||
|
|
||||||

||||||
|
|
||||||
|
## Development
|
||||||
|
|
||||||
|
To contribute bug patches or new features, you can use the github Pull Request model. It is assumed that code and documentation are contributed under the Apache License 2.0.

|
||||||
|
|
||||||
|
## Compatibility
|
||||||
|
|
||||||
|
This add-on is compatible with OpenNebula 4.6.
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
* Ruby >= 1.8.7
|
||||||
|
* gem fpm
|
||||||
|
* dpkg utils for deb package creation
|
||||||
|
* rpm utils for rpm package creation
|
||||||
|
|
||||||
|
On Ubuntu/Debian you can install the package `rpm` and you will be able to generate both rpm and deb packages.
|
||||||
|
|
||||||
|
## Use
|
||||||
|
|
||||||
|
### Package Description
|
||||||
|
|
||||||
|
Here are located the files needed to generate OpenNebula contextualization packages. The packages generated contain these files:
|
||||||
|
|
||||||
|
* `/etc/udev/rules.d/*` These files disable the udev network an cdrom
|
||||||
|
generation
|
||||||
|
* `/etc/init.d/vmcontext` This is the startup script that will try to mount
|
||||||
|
context cdrom, load contextualizaton variables,
|
||||||
|
call scripts in the contextualization scripts
|
||||||
|
directory and call init.sh if it exists in the
|
||||||
|
context cd.
|
||||||
|
* `/etc/one-context.d/*` This directory holds the scripts that will be
|
||||||
|
called by vmcontext script. They should be named
|
||||||
|
starting with a number so they are called in order.
|
||||||
|
|
||||||
|
By default only the network configuration context script is included in the
|
||||||
|
packages. These scripts are different for rpm and deb based distributions and
|
||||||
|
are located in `base_<deb|rpm>` directories.
|
||||||
|
|
||||||
|
The packages also have a post-install script that does these steps:
|
||||||
|
|
||||||
|
* Delete persistent cd and net rules from /etc/udev/rules.d
|
||||||
|
* Links vmcontext script to /etc/rc<runlevel>.d
|
||||||
|
* Deletes network configuration files
|
||||||
|
|
||||||
|
### Package Generation
|
||||||
|
|
||||||
|
The script `generator.sh` generates both deb and rpm packages and can be configured to include more files in the package or change some of its parameters.
|
||||||
|
|
||||||
|
On start it creates a temporary directory and copies there:
|
||||||
|
|
||||||
|
* `base` directory
|
||||||
|
* `base_<deb|rpm>` directory
|
||||||
|
* Any file or directory from the arguments.
|
||||||
|
|
||||||
|
Then these files are included in the package.
|
||||||
|
|
||||||
|
The default parameters to create a package are as follows:
|
||||||
|
|
||||||
|
VERSION=1.0.1
|
||||||
|
MAINTAINER=C12G Labs <support@c12g.com>
|
||||||
|
LICENSE=Apache
|
||||||
|
PACKAGE_NAME=one-context
|
||||||
|
VENDOR=C12G Labs
|
||||||
|
DESCRIPTION="
|
||||||
|
This package prepares a VM image for OpenNebula:
|
||||||
|
* Disables udev net and cd persistent rules
|
||||||
|
* Deletes udev net and cd persistent rules
|
||||||
|
* Unconfigures the network
|
||||||
|
* Adds OpenNebula contextualization scripts to startup
|
||||||
|
|
||||||
|
To get support use the OpenNebula mailing list:
|
||||||
|
http://opennebula.org/community:mailinglists
|
||||||
|
"
|
||||||
|
PACKAGE_TYPE=deb
|
||||||
|
URL=http://opennebula.org
|
||||||
|
|
||||||
|
You can change any parameter setting an environment variable with the same name. For example, to generate an rpm package with a different package name:
|
||||||
|
|
||||||
|
$ PACKAGE_TYPE=rpm PACKAGE_NAME=my-context ./generate.sh
|
||||||
|
|
||||||
|
You can also include new files. This is handy to, for example, include new scripts executed to contextualize an image. For example, we can have an script that install a user ssh key. We will create the file hierarchy that will go inside the package in a directory:
|
||||||
|
|
||||||
|
$ mkdir -p ssh/etc/one-context.d
|
||||||
|
$ cp <our-ssh-script> ssh/etc/one-context.d/01-ssh-key
|
||||||
|
$ ./generate.sh ssh/etc
|
||||||
|
|
||||||
|
NOTE: The generator must be executed from the same directory it resides.
