**Only Linux is supported.**
|
||||
|
||||
If you want to run it on OSX or Windows (untested) you can use Docker for it:
|
||||
If you want to run it on **OSX** or **Windows** (the last one is totally untested) you can do it using Docker:
|
||||
|
||||
```bash
|
||||
docker run --rm -i -t \
|
||||
--privileged \
|
||||
-v /var/run/docker.sock:/var/run/docker.sock \
|
||||
-v $(pwd):/build \
|
||||
-w /build \
|
||||
linkacloud/d2vm bash
|
||||
alias d2vm="docker run --rm -i -t --privileged -v /var/run/docker.sock:/var/run/docker.sock -v \$PWD:/build -w /build linkacloud/d2vm"
|
||||
```
|
||||
|
||||
## Supported VM Linux distributions:
|
||||
|
||||
Working and tested:
|
||||
|
||||
- [x] Ubuntu
|
||||
- [x] Debian
|
||||
- [x] Alpine
|
||||
|
||||
Need fix:
|
||||
|
||||
- [ ] CentOS / RHEL
|
||||
|
||||
The program use the `/etc/os-release` file to discovery the Linux Distribution and install the Kernel,
|
||||
if the file is missing, the build cannot succeed.
|
||||
|
||||
Obviously, **Distroless** images are not supported.
|
||||
|
||||
## Getting started
|
||||
|
||||
Clone the git repository:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/linka-cloud/d2vm && cd d2vm
|
||||
```
|
||||
|
||||
Install using the Go tool chain:
|
||||
|
||||
```bash
|
||||
go install ./cmd/d2vm
|
||||
which d2vm
|
||||
```
|
||||
```
|
||||
# Should be install in the $GOBIN directory
|
||||
/go/bin/d2vm
|
||||
```
|
||||
|
||||
Or use an alias to the **docker** image:
|
||||
|
||||
```bash
|
||||
alias d2vm="docker run --rm -i -t --privileged -v /var/run/docker.sock:/var/run/docker.sock -v \$PWD:/build -w /build linkacloud/d2vm"
|
||||
which d2vm
|
||||
```
|
||||
```
|
||||
d2vm: aliased to docker run --rm -i -t --privileged -v /var/run/docker.sock:/var/run/docker.sock -v $PWD:/build -w /build linkacloud/d2vm
|
||||
```
|
||||
|
||||
### Converting an existing Docker Image to VM image:
|
||||
|
||||
```bash
|
||||
b2vm convert --help
|
||||
```
|
||||
```
|
||||
Convert Docker image to vm image
|
||||
|
||||
Usage:
|
||||
d2vm convert [docker image] [flags]
|
||||
|
||||
Flags:
|
||||
-d, --debug Enable Debug output
|
||||
-f, --force Override output qcow2 image
|
||||
-h, --help help for convert
|
||||
-o, --output string The output image (default "disk0.qcow2")
|
||||
-O, --output-format string The output image format, supported formats: qcow2 qed raw vdi vhd vmdk (default "qcow2")
|
||||
-p, --password string The Root user password (default "root")
|
||||
--pull Always pull docker image
|
||||
-s, --size string The output image size (default "10G")
|
||||
|
||||
```
|
||||
|
||||
Create an image based on the **ubuntu** official image:
|
||||
|
||||
```bash
|
||||
sudo d2vm convert ubuntu -o ubuntu.qcow2 -p MyP4Ssw0rd
|
||||
```
|
||||
```
|
||||

You can now run your ubuntu image using the created `ubuntu.qcow2` image with **qemu**:

This system has been minimized by removing packages and content that are

not required on a system that users do not log into.

|
||||
To restore this content, you can run the 'unminimize' command.

### Building a VM Image from a Dockerfile
|
||||
|
||||
The example directory contains very minimalistic examples:
|
||||
|
||||
```bash
|
||||
cd examples
|
||||
```
|
||||
|
||||
*ubuntu.Dockerfile* :
|
||||
|
||||
```dockerfile
|
||||
FROM ubuntu
|
||||
|
||||
RUN apt update && apt install -y openssh-server && \
|
||||
echo "PermitRootLogin yes" >> /etc/ssh/sshd_config \
|
||||
|
||||
```
|
||||
|
||||
When building the vm image, *d2vm* will create a root password, so there is no need to configure it now.
|
||||
|
||||
Build the vm image:
|
||||
|
||||
The *build* command take most of its flags and arguments from the *docker build* command.
|
||||
|
||||
```bash
|
||||
d2vm build --help
|
||||
```
|
||||
|
||||
```
|
||||
Build a vm image from Dockerfile
|
||||
|
||||
Usage:
|
||||
d2vm build [context directory] [flags]
|
||||
|
||||
Flags:
|
||||
--build-arg stringArray Set build-time variables
|
||||
-d, --debug Enable Debug output
|
||||
-f, --file string Name of the Dockerfile (Default is 'PATH/Dockerfile') (default "Dockerfile")
|
||||
--force Override output image
|
||||
-h, --help help for build
|
||||
-o, --output string The output image (default "disk0.qcow2")
|
||||
-O, --output-format string The output image format, supported formats: qcow2 qed raw vdi vhd vmdk (default "qcow2")
|
||||
-p, --password string Root user password (default "root")
|
||||
-s, --size string The output image size (default "10G")
|
||||
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo d2vm build -p MyP4Ssw0rd -f ubuntu.Dockerfile -o ubuntu.qcow2 .
|
||||
```
|
||||
|
||||
Or if you want to create a VirtualBox image:
|
||||
|
||||
```bash
|
||||
sudo d2vm build -p MyP4Ssw0rd -f ubuntu.Dockerfile -O vdi -o ubuntu.vdi .
|
||||
```
|
||||
|
||||
### Complete example
|
||||
|
||||
A complete example setting up a ZSH workstation is available in the [examples/full](examples/full/README.md) directory.
|
||||
|
||||
|
||||
### Internal Dockerfile templates
|
||||
|
||||
You can find the Dockerfiles used to install the Kernel in the [templates](templates) directory.
|
||||
|
||||
### TODO / Questions:
|
||||
|
||||
- [ ] Create service from `ENTRYPOINT` `CMD` `WORKDIR` and `ENV` instructions ?
|
||||
- [ ] Inject Image `ENV` variables into `.bashrc` or other service environment file ?
|
||||
- [ ] Use image layers to create *rootfs* instead of container ?

|

|

PASSWORD=mysecurepasswordthatIwillneverusebecauseIuseMostlySSHkeys
|
||||
OUTPUT=workstation.qcow2
|

|
||||
```
|
||||
|
||||
Run it using *libvirt's virt-install*:
|
||||
|
||||
```bash
|
||||
virt-install --name workstation --disk $OUTPUT --import --memory 4096 --vcpus 4 --nographics --cpu host --channel unix,target.type=virtio,target.name='org.qemu.guest_agent.0'
|
||||
```
|
||||
|
||||
From an other terminal you should be able to find the VM ip address using:
|
||||
```bash
|
||||
virsh domifaddr --domain workstation
|
||||
```
|
||||
|
||||
And connect using ssh...
