Setup Docker containerized apache guacamole on centos 7 host.

Lets setup apache guacamole as your web based rdp vnc ssh gateway.
This is helpfull in case of your corporate environment also where you need to access your intranet network using port 443 only.

Install docker if you dont have already

 yum install docker -y
 systemctl enable docker
 systemctl start docker

Pull required container images

 docker pull guacamole/guacamole
 docker pull guacamole/guacd
 docker pull mysql/mysql-server

 Now run containers -

 docker run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --mysql > initdb.sql

 docker run --name mysql -e MYSQL_RANDOM_ROOT_PASSWORD=yes -e MYSQL_ONETIME_PASSWORD=yes -d mysql/mysql-server
 docker logs mysql
 docker cp initdb.sql mysql:/guac_db.sql
 docker exec -it mysql bash

Now setup required mysql database within container.
