1) Main Snap on bare metal
Install Wekan Snap to newest Ubuntu bare metal server. Snaps have automatic updates.
For example:
sudo apt-get install snapd
reboot
sudo snap install wekan
For Let's Encrypt SSL, like this to /var/snap/wekan/common/Caddyfile
. We will be proxying to inside LXD container:
boards.example.com {
tls {
alpn http/1.1
}
proxy / 10.10.10.231:3001 {
websocket
transparent
}
}
For CloudFlare SSL, like this to /var/snap/wekan/common/Caddyfile
:
http://boards.example.com https://boards.example.com {
tls {
load /var/snap/wekan/common/certificates
alpn http/1.1
}
proxy / 10.10.10.231:3001 {
websocket
transparent
}
}
2) New LXC container
So when I start new lxc container:
lxc launch images:ubuntu/20.04 lxccontainername
3) Snapd and Wekan
Then I go inside container and install snapd:
lxc exec lxccontainername -- /bin/bash
apt -y install snapd
reboot
lxc exec lxccontainername -- /bin/bash
snap install wekan
snap set wekan root-url='https://boards.example.com'
sudo snap set wekan port='3001'
sudo snap set wekan mail-from='Wekan Team Boards <[email protected]>'
sudo snap set wekan mail-url='smtps://username:[email protected]:587'
ip address
exit
That ip address
command does show current IP address of container, that you can then add to bare metal /var/snap/wekan/common/Caddyfile
.
You can also add more lxc containers to different subdomains and proxy to them in main Caddyfile.
4) Some LXC commands
New Ubuntu container
lxc launch images:ubuntu/20.04 lxccontainername
Inside LXC container
lxc exec lxccontainername -- /bin/bash
Running command in LXC
lxc exec lxccontainername -- apt install p7zip-full
Limit RAM available to LXC
lxc config set lxccontainername limits.memory 4GB
New Debian container
lxc launch images:debian/buster mydebiancontainername
New CentOS 7 container
lxc launch images:centos/7/amd64 centos
List containers
lxc list -cns
Result:
+---------------+---------+
| NAME | STATE |
+---------------+---------+
| mycontainer | RUNNING |
+---------------+---------+
Stop and delete container
lxc stop mycontainer
lxc delete mycontainer
