There is an action smeserver-docker-update
There is an action to update the core files:
{{Note box: Note to self - probably needs quotes around "false" for iptables}}
smeserver-docker-update
{{Note box| Note to self - probably needs quotes around "false" for iptables}}
config show docker
config show docker
systemctl status docker
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
curl -L https://github.com/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
/etc/e-smith/templates-custom/home/e-smith/files/docker/configs/docker-compose.yml
/etc/e-smith/templates-custom/home/e-smith/files/docker/configs/docker-compose.yml
To expand the template:
signal-event smeserver-docker-compose-update
signal-event smeserver-docker-compose-update
cd /home/e-smith/files/docker/configs
cd /home/e-smith/files/docker/configs
docker-compose up -d my_hello
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>

===File permissions===
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
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
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.
