Using docker containers on XCP-ng with Xen Orchestra CE step by step

1. Create a VM

In my tutorial I am cloning one existing VM.

To install docker and to prepare the xcp-ng host watch the following video. 

Or you could also continue to read it is up to you.

2. Inside the VM you have to install docker, openssh-server and ncat?

For ubuntu:

$ sudo apt install docker.io

$ sudo apt install openssh-server

$ sudo apt install ncat

To use docker has non-root add the user to the docker group inside your VM

like this.

$ sudo usermod -aG docker $(whoami)

Do not forget to logout and login are it may not work with your account

To check if docker is running  type the following

$ systemctl status docker

3. Then in your XCP-ng host you have to install xscontainer

Like this: 

$ yum install xscontainer 

Followed by executing 

$ xe-toolstack-restart

to restart the toolstack

and use the following command 

$ xscontainer-prepare-vm -v vmuuid -u christophe

4. Test your VM with container tab

$ sudo docker run hello-world

5. To install portainer execute the following command on your VM

$ sudo docker volume create portainer_data

$ sudo docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data portainer/portainer

Check the container tab.

Try portainer ip:9000 in your browser.
