yum install smeserver-extrarepositories-docker-ce
signal-event yum-modify
yum --enablerepo=smecontribs install smeserver-docker
(Note the contrib is still in smetest)
Uses config entries
config setprop docker iptables false/true - default false
config setprop docker DNS [192,168.10.1,8.8.8.8] - defaults to LocalIP
config setprop docker DockerNetwork [IP range eg 192.168.100.0/24] - defaults to dockers own choice. Range is not yet checked for validity.
There is an action smeserver-docker-update
{{Note box: Note to self - probably needs quotes around "false" for iptables}}
config show docker
status enabled/disabled - enabled by default
iptables true/false - false by default to prevent docker manipulating iptables
config show containerd
status enabled/disabled - enabled by default - called and used by docker
See if it works:
systemctl status docker
And test:
docker run hello-world
docker ps -a
docker rm <id>
docker images
docker rmi <id>
We can also use docker-compose:
curl -L https://github.com/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
chgrp docker /usr/local/bin/docker-compose
A test compose file is installed.
cd /home/e-smith/files/docker/configs
docker-compose up -d hello_world
Add your own templates to:
/etc/e-smith/templates/home/e-smith/files/docker/configs/docker-compose.yml
or:
/etc/e-smith/templates-custom/home/e-smith/files/docker/configs/docker-compose.yml
signal-event smeserver-docker-compose-update
cd /home/e-smith/files/docker/configs
docker-compose up -d my_hello

Docker attempts to guess what network to use and sets a bridged interface for it.

Using --net="host" means it is easier to connect to the container using the local IP address. Simple port forwarding/opening will suffice.
Using --network host means it is easier to connect to the container using the local IP address. Simple port forwarding/opening will suffice.
However, it exposes all ports on the container locally, and there may also be conflicts with local ports.

I am working on this currently but the LocalNetworking approach doesn't work. It probably need manipulation of the firewall with templates.

=== Login to container===
If permitted, most containers can be logged into using this:

===Using a Docker image===
You can still change the storage location in a later stage by copying all data to the new location you've defined with the -g argument.
You should generally be prefer to use docker-compose for images.

===Setting up a (Private) Docker repository===

The compose file is templated and makes managing docker images much easier.
==='Proposal test image:'===
An application that requires Java, PHP, Apache, MySQL and LDAP. The localhost MySQL and localhost LDAP should be used by the application. The application should be publicly available either on a subdomain or specific port on the FQDN. The application should only be available between 08:00AM until 19:00PM.
All application data should be incorporated by the default SME Sever backup mechanisms, including the image itself.
* Building the image based on centos6
* Configure networking, bridges and ports
* Start/restart and stop syntax of the application
* Configure cron

If you don't use host networking, you use the internal IP address set with docker, but this address is unknown as a local network to SME and it will block any queries emanating from the container. I am looking at this with the contrib.
