Ideas will come later, for now : hourra
[root@ns7loc13 ~]# db configuration set docker service status enabled [root@ns7loc13 ~]# signal-event nethserver-docker-update
you missed something, docker is down after the installation
EDIT : too fast, missing to read the README, it is wanted
I tested it on a VM (1 green interface) and on a gateway server (green and red)
On the gateway app templates are missing, I only got 8 templates. (usually there are more categories in the drop-down too):
I tried caddy and joomla but I always get to the Nethserver default page instead of the portainer apps when browsing to
Dedicated storage seems to work (docker volumes are created).
The portainer app button is missing.
After installation it worked but when I did
signal-event nethserver-docker-update more often, it happened that portainer was not reachable.
Ok I can create a basic container (tried alpine and ubuntu) think to use the good setting in portainer ->
interactive & tty
for the network, set an IP in the network range 172.28.0.0/16, I am not sure for the mac address it should work with the default one.
at least this what I missed first
It can be a symptom of a lack of connectivity. I ran this experiment:
- configured nethserver-docker on a green-only host
- added red interface later
- tried to ping from an alpine container
wget -qO- www.google.com
The ping was blocked. I found the
aqua0 bridge was DOWN. It wasn’t bring up by
interface-update event. So we need to add some logic to it, to bring it up again. This command was enough to work around the issue:
ip link set aqua0 up
Please check the
aqua0 state: if you find it DOWN take note of it!
just a quick test, and probably i miss something… i tested on a VM with only a green interface.
dedicated storage seems ok, but i cannot reach the exposed port of the container, any hints?
Forgot the Docker facilities that automatically expose a TCP port by altering the packet filtering / nat configuration : they are disabled in NethServer!
You have to define a port forward in the NethServer firewall configuration manually.
Edit: If you want to expose a web site, configure the Reverse Proxy
For developers: I think this can be done automatically (and easily) by an RPM too…
A post was split to a new topic: Help needed with firewall and nethserver-docker
For any one who is using the docker swarm and I repeat this is only for docker swarm
to install traefik reverse proxy
docker network create --driver=overlay traefik-net
this creates a new overlay network for traefik to work on
then we need to create the service
docker service create
then you can access it via local ip :8080
web where documentation for this
@stephdl, I tried to install nethserver-docker recently and never succeed to log onto portainer; always got 500 server errors.
Decided it was really too cutting edge technology and preferred to go for a DO droplet and uninstalled the thing.
Now I get plenty of those messages :

Maybe there is something not handled when uninstalling.
