Upgrade Guacamole server v612

This section describes how to upgrade the Guacamole server as part of the upgrade to Abiquo 6.1.2 or higher. This upgrade is for remote access to public cloud and it is optional for customers using WebMKS only

To use the latest version of Guacamole, do these steps to install and run it in a Docker container on each Remote Services server.

Log in to the Remote Services server and run the following commands.

yum install docker

/usr/bin/systemctl enable docker

/usr/bin/systemctl start docker

/usr/bin/systemctl stop guacd

docker pull guacamole/guacd 

docker run -t --name guacd -d -p 4822:4822 guacamole/guacd:latest

To check that the container was created correctly, run docker ps and check the output.

Create the Docker Guacamole service file

cat > /etc/systemd/system/docker.guacamole.service <<EOF

```

Restart the services.

/usr/bin/systemctl disable guacd
