This is a simple NAS backup plugin for KVM which may be later expanded for other hypervisors. This backup plugin aims to use shared NAS storage on KVM hosts such as NFS (or CephFS and others in future), which is used to backup fully cloned VMs for backup & restore operations. This may NOT be as efficient and performant as some of the other B&R providers, but maybe useful for some KVM environments who are okay to only have full-instance backups and limited functionality. Design & Implementation follows the `networker` B&R plugin, which is simply: - Implement B&R plugin interfaces - Use cmd-answer pattern to execute backup and restore operations on KVM host when VM is running (or needs to be restored) - instead of a B&R API client, relies on answers from KVM agent which executes the operations - Backups are full VM domain snapshots, copied to a VM-specific folders on a NAS target (NFS) along with a domain XML - Backup uses libvirt feature: https://libvirt.org/kbase/live_full_disk_backup.html orchestrated via virsh/bash script (nasbackup.sh) as the libvirt-java lacks the bindings - Supported instance volume storage for restore operations: NFS & local storage Refer the doc PR for feature limitations and usage details: https://github.com/apache/cloudstack-documentation/pull/429 Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com> Co-authored-by: Pearl Dsilva <pearl1594@gmail.com> Co-authored-by: Abhishek Kumar <abhishek.mrt22@gmail.com> Co-authored-by: Suresh Kumar Anaparti <sureshkumar.anaparti@gmail.com>
CloudStack RPM and DEB packaging
This directory contains all the required scripts and tools needed to build RPM and DEB packages for Apache CloudStack.
These scripts are also used by the CloudStack team to build packages for the official release of CloudStack.
Requirements
The RPM and DEB packages have dependencies on versions of specific libraries. Due to these dependencies the following distributions and their versions are supported by the packages.
- CentOS / RHEL: 8 and 9
- Ubuntu: 20.04, 22.04, 24.04
- Debian 12 (Bookworm, untested!)
Building
Using the scripts in the packaging directory the RPM and DEB packages can be build.
DEB
If you simply want to build packages go to the root directory of your CloudStack source code and run:
dpkg-buildpackage
This will build packages for the current distribution version you are running. If you run this on a Ubuntu 16.04 system the packages will be tailored for Ubuntu 16.04 and will not install on Ubuntu 14.04.
Building cross-distribution
If you want to build packages for a different distribution run the build-deb.sh script. This will build packages with the current distribution as a suffix to the package names. E.g. cloudstack-agent_4.9.0~xenial_all.deb
Using a Docker image you can build packages for a distribution you are not running.
The following commands assume that the CloudStack source is present in /tmp/cloudstack on the system you are running these commands on.
docker run -ti -v /tmp:/src ubuntu:16.04 /bin/bash -c "apt-get update && apt-get install -y dpkg-dev python debhelper openjdk-8-jdk genisoimage python-mysql.connector maven lsb-release devscripts && /src/cloudstack/packaging/build-deb.sh"
docker run -ti -v /tmp:/src ubuntu:14.04 /bin/bash -c "apt-get update && apt-get install -y dpkg-dev python debhelper openjdk-7-jdk genisoimage python-mysql.connector maven lsb-release devscripts && /src/cloudstack/packaging/build-deb.sh"
docker run -ti -v /tmp:/src ubuntu:22.04 /bin/bash -c "apt-get update && apt-get install -y software-properties-common &&apt-add-repository universe --yes && apt-get update && apt-get install -y dpkg-dev debhelper lsb-release devscripts openjdk-11-jdk libws-commons-util-java genisoimage libcommons-codec-java libcommons-httpclient-java liblog4j1.2-java maven python3 python3-mysql.connector python3-setuptools python-setuptools python3-openssl python3-dev libffi-dev build-essential libssl-dev libffi-dev fakeroot python-is-python3 && curl -sL https://deb.nodesource.com/setup_14.x | bash - && apt-get install -y nodejs && /src/cloudstack/packaging/build-deb.sh"
The commands above will generate Ubuntu 14.04, 16.04, and 22.04 packages which you will find in /tmp on your system after the build succeeds.
RPM
The package.sh script can be used to build RPM packages for CloudStack. In the packaging script you can run the following command:
./package.sh --pack oss --distribution el8
