https://192.168.60.55:9443

Click on Environments Local.

5.1.1 Each Joomla instance has its container.

  • cnt_jla_wb_number.
  • cnt_jla_db_number.
    Containers will be created from the docker compose command line.

5.1.2 Each Joomla instance has its network.

  • net_jla_number.
    Create net_jla_1.
Select Networks.  
Add network.  
Name : net_jla_1  
Add Driver options:  
Name : com.docker.network.bridge.name   value : net_jla_1  
Create the network.

Name: com.docker.network.bridge.name value : net_jla_1 is not specified, docker will give it a name as br-XXXX.

5.1.3 Each Joomla instance has its volume.

  • vol_jla_wb_number.
  • vol_jla_db_number.
    Create these volumes.
Select Volumes.  
Add volume.  
Name: vol_jla_wb_1  
Create the volume.  
Add the volume.  
Name: vol_jla_db_1  
Create the volume.

5.1.4 Information.

Command lines to create the netwok and volumes without portainer.
docker network create --opt com.docker.network.bridge.name=net_jla_1 net_jla_1
docker volume create vol_jla_wb_1
docker volume create vol_jla_db_1

5.2 Give permissions to www-dock and mysql-dock for volumes.

chown -R www-dock:www-dock /var/lib/docker/volumes/vol_jla_wb_1
chown -R mysql-dock:mysql-dock /var/lib/docker/volumes/vol_jla_db_1

5.3 Install Drupal with a yaml script.

Certain parameters like Memory Limit, Upload_max_filesize, ... for joomla are defined in php.ini.

mkdir -p /home/teacher/docker/files
vi /home/teacher/docker/files/php.ini

memory_limit = 500M  
upload_max_filesize = 500M  
post_max_size = 500M  
max_execution_time = 30  
upload_tmp_dir = /tmp

you can modify /home/teacher/docker/files/php.ini but not delete it.

Installation.
docker compose -f /home/teacher/joomla/instance_joomla_1.yaml up
Crtl+C to stop.

Information.
If you want to change your joomla instance in 2,
edit this file and replace _1 by _2.
Then replace the port 8081 by 8082
and 33771 by 33772.

5.4 Attach volumes with containers.

On portainer, by default the volumes are marked Unused.

Open Portainer.
https://192.168.60.55:9443

Click on Environments Local.

Select Container cnt_jla_wb_1.
Click on cnt_jla_wb_1.
Click Duplicate/Edit.
Advanced container settings.
Click on Volumes.

5.5 Open Joomla.

5.5.1 Firewall.

Find your interface for network net_jla_1.
The gateway is displayed in Portainer Networks.
Example:
The net_jla_1 gateway is 172.18.0.1/16.
Network interface is net_jla_1.

ifconfig

net_jla_1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500  
        inet 172.18.0.1  netmask 255.255.0.0  broadcast 172.18.255.255  
        ether 02:42:6a:71:3d:51  txqueuelen 0  (Ethernet)  
        RX packets 10742  bytes 23229052 (22.1 MiB)  
        RX errors 0  dropped 0  overruns 0  frame 0  
        TX packets 12571  bytes 5854522 (5.5 MiB)  
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Add rules on firewall.
iptables -t nat -A POSTROUTING ! -o net_jla_1 -s 172.18.0.0/16 -j MASQUERADE
ufw route allow in on net_jla_1 out on eth0 to any from any

The postrouting iptable rule disappears after restarting the server.
The solution is to add the rule in crontab.
Add postrouting iptable in /opt/docker/postrouting_sh.

vi /opt/docker/postrouting_sh

iptables -t nat -A POSTROUTING ! -o net_jla_1  -s 172.18.0.0/16 -j MASQUERADE

Don't forget to delete line if you no longer use this iptable rule.

Information:
To delete an iptable postrouting rule without reboot.
Postrouting line number.
iptables --list -v --line-numbers -t nat
Remove rule ( 1 is the line number).
iptables -t nat -D POSTROUTING 1
