It is still amazing to see that the number of contributions and suggestions from the community continues to grow for my free and simple VM backup solution called ghettoVCB. I created ghettoVCB almost 8 years ago which now has over 1.2 million views, pretty insane if you ask me! Although I am quite busy these days which includes a new born, I still try to find time to update the script as time permits. A couple of weeks back I received an email from one of my readers who came across ghettoVCB and was quite happy with the free solution. He also had some feedback asking why I did not provide an installable VIB for ghettoVCB?
A totally valid question and the answer was quite simple. When I had first created ghettoVCB back in the classic ESX 3.x days, the concept of a VIB had not existed yet. With the release of ESXi 5.0, the idea of the VIB was introduced but it was only recently in 2012 did VMware publish a method for customers to create custom VIBs for ESXi using the VIB Author Fling. I do have to admit at one point I did think about providing a VIB for ghettoVCB, but I guess I never went through with it for whatever reason. Looking back now, this was a no-brainer to provide a simplified user experience and not to mention the benefit of having ghettoVCB installed as a VIB is that it will automatically persist on ESXi after reboots which was a challenge for new users to ESXI.
So without further ado, here is ghettoVCB provided in either a VIB or offline bundle form:
To install the ghettoVCB VIB, you just need to download the VIB and run the following ESXCLI command and specifying the full path to the VIB:
esxcli software vib install -v /vghetto-ghettoVCB.vib -f
Once installed, you will find all ghettoVCB configuration files located in:
/etc/ghettovcb/ghettoVCB.conf
/etc/ghettovcb/ghettoVCB-restore_vm_restore_configuration_template
/etc/ghettovcb/ghettoVCB-vm_backup_configuration_template
Both ghettoVCB and ghettoVCB-restore scripts are located in:
/opt/ghettovcb/bin/ghettoVCB.sh
/opt/ghettovcb/bin/ghettoVCB-restore.sh
One additional thing I would like to point out is that you can also quickly tell which version of ghettoVCB is running by inspecting the installed VIB by using the following ESXCLI command:
esxcli software vib get -n ghettoVCB
If you look at the screenshot above, I have highlighted two important pieces of information in green. The first is the "Description" property which includes the Github commit hash of the particular revision of ghettoVCB and the "Creation Date" property which contains the date of that commit. This can be handy if you want to compare it to the latest ghettoVCB repository found on Github here. Thanks again Markus for the suggestion!
For those of you who are interested in the details for creating your own ghettoVCB VIB, the next section is specifically for you. Earlier this week I blogged about a Docker Container that I have created to help build custom ESXi VIBs and as you can see now, that was the basis for us to be able to quickly create ghettoVCB VIB based on the latest revision of the script.
Step 1 - Create a new Docker Machine following the steps outlined here.
Step 2 - Login to the Docker Machine and create a new Dockerfile which contains the following:
FROM lamw/vibauthor # Due to https://stackoverflow.com/a/49026601 RUN rpm --rebuilddb RUN yum clean all RUN yum update -y nss curl libcurl;yum clean all # Download ghettoVCB VIB build script RUN curl -O https://raw.githubusercontent.com/lamw/vghetto-scripts/master/shell/create_ghettoVCB_vib.sh && chmod +x create_ghettoVCB_vib.sh # Run ghettoVCB VIB build script RUN /root/create_ghettoVCB_vib.sh CMD ["/bin/bash"]
Step 3 - Next we need to build our new Docker Container which will use the VIB Author Container by running the following command:
docker build -t lamw/ghettovcb .
The output will be quite verbose, but what you will be looking for is text highlighted in green as shown in the screenshot above. You should see the successful build of both the VIB and offline bundle as well as Docker Container showing a successful build.
Step 4 - After a successful build of our Docker Container, we can now launch the container by running the following command:
docker run --rm -it lamw/ghettovcb
Once logged into the Docker Container, you will see the generated VIB and the offline bundle for ghettoVCB as shown in the screenshot above.
If you wish to copy the VIB and offline bundle out of the Docker Container into the Docker Host, you can use Docker Volumes. I found this useful thread over on Stack overflow which I have modified to include the copying of the ghettoVCB VIB and offline bundle out to Docker Host by running the following command:
docker run -i -v ${PWD}/artifacts:/artifacts lamw/ghettovcb sh << COMMANDS
cp vghetto-ghettoVCB* /artifacts
COMMANDS
Finally, to copy the ghettoVCB VIB from the Docker Host to your desktop, we first need to identify the IP Address given to our Docker Machine by running the following command:
docker-machine ip osxdock
Currently, Docker Machine does not include a simple "scp" command so we will need to use regular scp command and specify the private SSH keys which you can find by running "docker-machine inspect [NAME-OF-DOCKER-HOST]" and connecting to our Docker Host to copy the ghettoVCB VIB by running the following command:
scp -i /Users/lamw/.docker/machine/machines/osxdock/id_rsa [email protected]:artifacts/vghetto-ghettoVCB.vib .
