===Contrib===
===Contrib===
There is a contrib that will set up a lot of this for you in the Reetp Repo:
yum --enablerepo=extras install epel-release.
yum install smeserver-extrarepositories-docker-ce
signal-event yum-modify
yum --enablerepo=smecontribs,extras,epel install smeserver-docker
signal-event post-upgrade;signal-event reboot
(Note the contrib is still in smetest)
====Avoiding conflicts====
docker-compose templates used:
smeserver-docker
01version
10HelloWorldTest
smeserver-rocketchat
20rocketchat
====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 to update the core files:
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
====Testing====
We can run docker directly but the preferred method is to use 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
To expand the template:
signal-event smeserver-docker-compose-update
cd /home/e-smith/files/docker/configs
docker-compose up -d my_hello
Using plain docker:
docker run hello-world
Other commands:
docker ps -a
docker rm <id>
docker images
docker rmi <id>
==Things to do==
Plenty
===Challenges===
* How to interact with localhost PAM or LDAP from within a container?
I think that you can access localhost services by adding:
--net="host" to docker run
This means any services on the docker container are equally valid 'localhost' services accessible from the server itself so you need to ensure the server is properly firewalled. See Issues below.
* Many more...
==Notes==
====Networking====
====Networking====
{{Note box | See Issues and other comments further down re host/bridged networking}}
{{WIP box | This is still a work in progress. the following are notes for reference only}}
Docker attempts to guess what network to use and sets a bridged interface for it.

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:
If permitted, most containers can be logged into using this:
docker exec -t -i -u root <container_name> /bin/bash
docker exec -t -i -u root <container_name> /bin/bash
===SME Server specifics===
By default Docker will store all images, containers and other data in:
/var/lib/docker
For SME Server this is not ideal for we would like to incorporate all Docker data into the pre-defined backup procedure(s) that come with SME Server. The preferred location for Docker data would be:
'''/home/e-smith/files/docker'''
===File permissions===
Docker requires some RPM's that are not available in the default upstream repo's. So we need to enable the epel repo first. See ''[[epel]]''
You may have issues writing to local filesystems from Docker images.
First add something like this to your compose file
volumes:
- /opt/uploads/:/opt/uploads/
You may need to find out what permissions are required.
In RocketChat I had to add a dummy user and group like this
In this file you can set default parameters which are applicable to all containers run by Docker. By default it holds no arguments. All arguments can also be set manually when starting a container, in which case each individual container can have it's specific parameters. To see a list all available arguments that can be used in the Docker configuration file enter:
mkdir -p /opt/uploads
chmod 0777 /opt/uploads
I then could upload and check the ID that docker users. I thins case it was 65533
/var/lib/docker
So I then did:
groupadd -g 65553 rocketchat
useradd -s /sbin/nologin -u 65533 -d /dev/null -g rocketchat rocketchat
chmod 0744 /opt/uploads
And then test again.
===Using a Docker image===
You should generally be prefer to use docker-compose for images.

==='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.

* Configure networking, bridges and ports
* Start/restart and stop syntax of the application
* Configure cron
==General old notes==
The following methods and notes are left for reference.
and if it created the storage layout correctly:
By default, there are pre-built images available from the official [https://registry.hub.docker.com/ Docker Hub]. In our examples we will use the pre-built centos7 image.

To get a list of all available Centos images you can use:

You will be flooded with available images from the Docker hub. This is because everyone can have a free account on Docker hub and create one repository for him/herself. We limit our testing to the official Centos repo. With all the other images, you are on your own and usage is at your own risk.

To download the centos6 image to your local server, issue the following command as root:
To download the centos7 image to your local server, issue the following command as root:
docker pull centos:centos6
docker pull centos:centos7
where the syntax is 'centos' as the main repository and 'centos6' the specific version. Would you issue only 'docker pull centos', then all centos versions will be downloaded. So be specific.

===Docker Name resolution===
===Docker Name resolution===
Other DNS can be added to the unit file or daemon.json - see further below for details.
Or you could add directly from the command line
docker run -i -t -dns 208.67.220.220 -dns 208.67.220.222 sme9_real:6.5 /bin/bash
===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
===Shipyard web GUI===
Deprecated
There is a separate page on how to install Shipyard, the Docker web GUI [http://wiki.contribs.org/Shipyard here]
===Issues===
This was a v9 issue. Leaving for reference.
You will find that if you use 'host' networking docker will set /sys as Read Only and you will get an error with the raid_check as per this bug
https://bugs.contribs.org/show_bug.cgi?id=10660
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.
===Repo setup===
db yum_repositories set docker-ce-stable repository \
BaseURL 'https://download.docker.com/linux/centos/7/$basearch/stable' \
EnableGroups no \
GPGCheck yes \
GPGKey https://download.docker.com/linux/centos/gpg \
Name 'Docker Stable' \
Visible yes \
status enabled
signal-event yum-modify
yum --enablerepo=extras,docker-ce-stable install docker-ce docker-ce-cli
or to try with the smeserver-docker contrib - still modifying this
yum --enablerepo=extras,smetest install smeserver-docker
So we get a service in /etc/systemd/system-preset/49-koozali.preset
config set docker service status enabled
config set containerd service status enabled
mkdir -p /home/e-smith/files/docker
mkdir -p /home/e-smith/files/docker/configs
Startup options
The big issue is getting this to work correctly with the firewall.
https://docs.docker.com/compose/compose-file/compose-file-v3
Host mode where the container has the same IP as the server and the service runs the same as any other host service, and can talk to other local host services easily, but exposes the container more.
Bridge mode where the container is on it's own internal docker network that is bridged to the local machine, but then queries emanating from the container will have the internal docker IP and can be refused by real 'local' services eg AD/MySQL etc. unless the firewall or other services can be adjusted.
https://docs.docker.com/compose/compose-file/compose-file-v3/#network_mode
network_mode: "bridge"
network_mode: "host"
network_mode: "none"
network_mode: "service:[service name]"
network_mode: "container:[container name/id]"
https://docs.docker.com/compose/compose-file/compose-file-v3/#ports
Port mapping is incompatible with network_mode: host
https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file
We can add startup options via /etc/docker/daemon.json
===Files to modify?===
For now I have created a hardcoded file with the content from below
mkdir -p /usr/lib/systemd/system/docker.service.d
/usr/lib/systemd/system/docker.service.d/50koozali.conf
If we template then we would use two fragments like this:
/etc/e-smith/templates/usr/lib/systemd/system/docker.service.d/50koozali.conf/40service
[Service]
docker run -i -t -dns 208.67.220.220 -dns 208.67.220.222 sme9_real:6.5 /bin/bash
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
# docker home set to /home/e-smith/files/docker
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -g /home/e-smith/files/docker/data
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always
/etc/e-smith/templates/usr/lib/systemd/system/docker.service.d/50koozali.conf/80install
[Install]
WantedBy=sme-server.target
--net="host" to docker run
expand-template /usr/lib/systemd/system/docker.service.d/50koozali.conf
But now we can use /etc/docker/daemon.json
This can be templated. Key point to avoid is a conflict between the docker internal network and out own.
We also want to know what is happening with IPTables rules
eg
{
"bip": "192.168.100.1/24", << Set our own choice of internal network
"data-root": "/home/e-smith/files/docker/data", << set our own data directory
"dns": ["127.0.0.1", "192.168.10.212"] << set our own DNS
}
===Docker Networking===
Docker now does it's own thing with IPTables and it is hard to disable - we need to be careful here
https://docs.docker.com/network/iptables/
How do we check conflicts?
ip addr show docker0
docker network ls
docker=service
docker network inspect bridge
https://www.baeldung.com/ops/docker-network-information
docker network inspect -f '{{range .IPAM.Config}}{{.Subnet}}{{end}}' bridge
172.17.0.0/16
So one way is to add it to the daemon.json file (see above)
{
"iptables": false
}
And note:
Restart the Docker daemon and voila: your containers will not be exposed to every possible interface but you will need to explicitly manipulate your iptables rules if you want the traffic to pass through, e.g.: this is needed to NAT your containers:
-A POSTROUTING -s 172.17.0.0/24 -o eth0 -j MASQUERADE
An alternative which I use on RocketChat is to proxy calls using mod_proxy_tunnel.so
/etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/20LoadModule98ExtraMod
{
# Load wstunnel if available
if ( -e '/usr/lib64/httpd/modules/mod_proxy_wstunnel.so' ||
-e '/usr/lib/httpd/modules/mod_proxy_wstunnel.so') {
$OUT .= "LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so\n";
}
}
You can then use some custom httpd templates to create a proxy pass virtual host.
