# MSVSphere Cloud Images
|
|
|
|
[Packer](https://www.packer.io/) templates and configuration files for
|
|
building MSVSphere images for various cloud platforms.
|
|
|
|
|
|
## Build environment configuration
|
|
|
|
Supported operating systems:
|
|
|
|
* MSVSphere 9 and other EL9-compatible distributions
|
|
* Fedora
|
|
|
|
First install Ansible, which we use for virtual machines provisioning:
|
|
|
|
```shell
|
|
$ dnf install ansible-core
|
|
```
|
|
|
|
Then follow the Packer installation [instructions](https://developer.hashicorp.com/packer/downloads?product_intent=packer).
|
|
|
|
Alternatively, you can install a Packer binary from a Yandex
|
|
[mirror](https://hashicorp-releases.yandexcloud.net/packer/): just download a
|
|
latest version archive and unzip it somewhere in PATH (e.g. `~/.local/bin`).
|
|
|
|
Verify that Packer works:
|
|
|
|
```shell
|
|
$ packer version
|
|
1.9.4
|
|
```
|
|
|
|
In order to install required Packer plugins run the following command in the
|
|
project root:
|
|
|
|
```shell
|
|
$ packer init -upgrade .
|
|
```
|
|
|
|
Dependently on your network configuration, you may also need to open the
|
|
8000-9000 TCP port range so that Packer can serve kickstart files to VMs:
|
|
|
|
```shell
|
|
$ firewall-cmd --zone=public --add-port=8000-9000/tcp --permanent
|
|
$ firewall-cmd --reload
|
|
```
|
|
|
|
You will also need to install either QEMU/KVM or VirtualBox or
|
|
VMWare Workstation, depending on what types of images you are going to build.
|
|
|
|
For VirtualBox and VMWare Workstation just follow the official site
|
|
documentation.
|
|
|
|
The QEMU/KVM installation instructions are provided below:
|
|
|
|
```shell
|
|
# for MSVSphere 9
|
|
$ dnf install edk2-ovmf libvirt libvirt-daemon-kvm
|
|
|
|
# for Fedora
|
|
$ dnf install @virtualization
|
|
$ dnf install edk2-ovmf
|
|
```
|
|
|
|
|
|
## Building images
|
|
|
|
In order to build an image use the following command syntax:
|
|
|
|
```shell
|
|
$ packer build -only=${BUILDER}.${CONFIGURATION} .
|
|
```
|
|
|
|
where `${BUILDER}` is a Packer builder (e.g. `virtualbox-iso`) and
|
|
`${CONFIGURATION}` is an image configuration name (e.g.
|
|
`msvsphere-9-vagrant-x86_64`).
|
|
|
|
On Fedora you might need to provide extra options because it has different
|
|
paths for qemu-kvm and edk2 firmware:
|
|
|
|
```shell
|
|
$ packer build -var qemu_binary=/usr/bin/qemu-kvm \
|
|
-var uefi_ovmf_code=/usr/share/OVMF/OVMF_CODE.fd \
|
|
-var uefi_ovmf_vars=/usr/share/OVMF/OVMF_VARS.fd \
|
|
-only=${BUILDER}.${CONFIGURATION} .
|
|
```
|
|
|
|
A graphical VM console is disabled by default, but you can enable it for
|
|
debugging purposes by setting the `headless` variable to `false`:
|
|
|
|
```shell
|
|
$ packer build -only=vmware-iso.msvsphere-9-vagrant-x86_64 \
|
|
-var headless=false .
|
|
```
|
|
|
|
See the [variables.pkr.hcl](variables.pkr.hcl) file for other supported
|
|
variables.
|
|
|
|
|
|
### Building Generic Cloud images
|
|
|
|
Generic Cloud image build command:
|
|
|
|
```shell
|
|
$ packer build -only=qemu.msvsphere-9-gencloud-x86_64 .
|
|
```
|
|
|
|
|
|
### Building Vagrant boxes
|
|
|
|
VirtualBox Vagrant box build command:
|
|
|
|
```shell
|
|
$ packer build -only=virtualbox-iso.msvsphere-9-vagrant-x86_64 .
|
|
```
|
|
|
|
VMWare Vagrant box build command:
|
|
|
|
```shell
|
|
$ packer build -only=vmware-iso.msvsphere-9-vagrant-x86_64 .
|
|
```
|
|
|
|
## Debugging image builds
|
|
|
|
Use `PACKER_LOG=1` environment variable definition to get extra debug output
|
|
from Packer:
|
|
|
|
```shell
|
|
$ PACKER_LOG=1 packer build ...
|
|
```
|
|
|
|
other Packer debugging techniques are described in the Packer
|
|
[documentation](https://developer.hashicorp.com/packer/docs/debugging).
|
|
|
|
Add `-vvvv` flag to the Ansible's `extra_arguments` block in a Packer config
|
|
in order to get verbose output from Ansible:
|
|
|
|
```hcl
|
|
build {
|
|
provisioner "ansible" {
|
|
...
|
|
extra_arguments = [..., "-vvvv"]
|
|
}
|
|
}
|
|
```
|
|
|
|
Additionally, you can connect to Packer's VNC session using a VNC client.
|
|
For TigerVNC you will need to enable the following settings:
|
|
|
|
* Input -> View only (ignore mouse and keyboard)
|
|
* Misc -> Shared (don't disconnect other viewers)
|
|
|
|
By default Packer is running a VNC server on a random TCP port in the
|
|
5900:6000 range. But for remote build environments it might be useful
|
|
to use a specific port so that you can configure a firewall easily:
|
|
|
|
```shell
|
|
$ packer build ... -var vnc_bind_address=0.0.0.0 -var vnc_port_min=5900 \
|
|
-var vnc_port_max=5900 .
|
|
```
