What about Docker on NethServer 7?

Feature
53

something more workable with the portainer container (persistent data and start at boot if not stopped)

yum update -y
curl -fsSL https://get.docker.com/ | sh

the service docker must be tricked with shorewall

cp /lib/systemd/system/docker.service /etc/systemd/system/docker.service
vim /etc/systemd/system/docker.service

then change

    -After=network.target firewalld.service
    +After=network.target shorewall.service

and to bind the 0.0.0.0 IP to your real IP, like this you will be able to reach the tcp port of your container directly in portainer (set the IP of your server)

-ExecStart=/usr/bin/dockerd 
+ExecStart=/usr/bin/dockerd --ip=xxx.xxx.xxx.xxx

then update the docker service

systemctl daemon-reload
systemctl enable docker
systemctl start docker

create default entries

mkdir /etc/e-smith/db/configuration/defaults/docker
echo 'service' > /etc/e-smith/db/configuration/defaults/docker/type
echo 'enabled' > /etc/e-smith/db/configuration/defaults/docker/status

/etc/e-smith/events/actions/initialize-default-databases

config setprop firewall Docker enabled
signal-event firewall-adjust

create and launch the portainer docker

mkdir /var/lib/portainer
docker run -d -p 9000:9000 --restart unless-stopped --name portainer-container -v /var/lib/portainer:/data -v "/var/run/docker.sock:/var/run/docker.sock" portainer/portainer

a good article to read : https://media-glass.es/portainer-the-ui-for-docker-d067f6335f23

to update portainer, you need to update the image, then remove the container and create it again. Since the data is persistent on the host, you will found all your settings.

  • update all your images

docker images | awk '/^REPOSITORY|\<none\>/ {next} {print $1}' | xargs -n 1 docker pull

  • stop portainer

docker kill portainer-container

  • remove portainer

docker rm portainer-container

  • create again portainer

docker run -d -p 9000:9000 --restart unless-stopped --name portainer-container -v /var/lib/portainer:/data -v "/var/run/docker.sock:/var/run/docker.sock" portainer/portainer
