Positive: it’s lxc based.
Negative: it seems to focus a lot on the “I got hello world running in x minutes”. A dedicated keyword for “database”? What crazy logic is that??

That DB keyword basically allows you to roll out a linked database container for your app if required. Only Mysql and Postgresql is currently supported. These are Mysql and Postgresql instances that can be used for this.
A lot of apps require databases and instead of configuring it manually this allows some degree of automation so a linked database container can be easily deployed if required.
> Please disable Selinux or any firewalls before configuring containers, networks, storage and cluster services. They can interfere in unpredictable ways. Once configured services are working you can add the relevant exceptions and enable them again.
Similarly when creating overlay networks ports across systems need to be open. The idea behind this is users can ensure the functionality is working as desired before enabling firewalls and other security features so they can debug issues effectively.
We have tried to provide a lot of documentation so new users can get started and get comfortable with containers and networking. Often users get discouraged if even after following the docs they run into issues.
But, yeah - people tend to only skim the manuals.
