Pulling

docker pull tikiwiki/tikiwiki:19.x

Running

Variables

Some env variables are provided to setup the database, but you can also mount your configurations files inside container. The env vars and the default values are listed below and the names are self explanatory.

TIKI_DB_VERSION=19
TIKI_DB_HOST='db'
TIKI_DB_USER
TIKI_DB_PASS
TIKI_DB_NAME=tikiwiki

Single container

Example to get a running container below.

docker run --rm --name tiki --link mariadb:db \
    -e TIKI_DB_USER=tiki \
    -e TIKI_DB_PASS=wiki \
    -p 80:80 \
    -d tikiwiki/tikiwiki

docker-compose

The following creates and start two containers:

TikiWiki with por 80 published on host
MariaDB instance with the schema tikiwiki

version: '2'
services:
  tiki:
    image: tikiwiki/tikiwiki:19.x
    ports:
    - "80:80"
    depends_on:
      - db
    environment:
      - TIKI_DB_USER=tiki
      - TIKI_DB_PASS=wiki
      - TIKI_DB_NAME=tikiwiki
  db:
    image: mariadb
    environment:
      - MYSQL_USER=tiki
      - MYSQL_PASSWORD=wiki
      - MYSQL_DATABASE=tikiwiki
      - MYSQL_ROOT_PASSWORD=tkwkiiii
      - TERM=dumb

scalable mode with docker-compose

The following recipe makes possible to grow the amount of TikiWiki containers, so in this way, it is possible to use more resources from host to handle incoming traffic.

Concerning about this mode:

It it not compatible to web installer, so installing database using command line is needed.
It is needed to have a reverse proxy load balancing traffic to TikiWiki containers.

docker-compose.yml

This setup uses eeacms/haproxy container as reverse proxy and load balancer and declare a set of volumes. When new tiki containers are created, they will share the same set of volumes.

version: '3.7'

services:
  haproxy:
    image: eeacms/haproxy
    depends_on:
    - tiki
    ports:
    - "80:5000"
    environment:
      BACKENDS: "tiki"
      DNS_ENABLED: "true"
      LOG_LEVEL: "info"
  tiki:
    image: tikiwiki/tikiwiki:19.x
    depends_on:
      - db
    deploy:
      replicas: 2
    environment:
      - TIKI_DB_USER=tiki
      - TIKI_DB_PASS=wiki
      - TIKI_DB_NAME=tikiwiki
    volumes:
      - tiki_files:/var/www/html/files/
      - tiki_img_trackers:/var/www/html/img/trackers/
      - tiki_img_wiki_up:/var/www/html/img/wiki_up/
      - tiki_img_wiki:/var/www/html/img/wiki/
      - tiki_modules_cache:/var/www/html/modules/cache/
      - tiki_storage:/var/www/html/storage/
      - tiki_temp:/var/www/html/temp/
      - tiki_sessions:/var/www/sessions/
  db:
    image: mariadb
    environment:
      - MYSQL_USER=tiki
      - MYSQL_PASSWORD=wiki
      - MYSQL_DATABASE=tikiwiki
      - MYSQL_ROOT_PASSWORD=tkwkiiii
      - TERM=dumb
volumes:
  tiki_files:
  tiki_img_trackers:
  tiki_img_wiki_up:
  tiki_img_wiki:
  tiki_modules_cache:
  tiki_storage:
  tiki_temp:
  tiki_sessions:

Starting containers

First it is needed to copy the YML above in a folder with a descriptive name, like example.com.

Then, inside the folder example.com, the following command starts all container from docker-compose.yml.

docker-compose up -d

After wait all containers to start and the console prompt appears again, the following command shows the containers running for docker-compose.yml on folder example.com.

docker-compose ps

The output should be like:

        Name                      Command               State          Ports        
------------------------------------------------------------------------------------
examplecom_db_1        docker-entrypoint.sh mysqld      Up      3306/tcp            
examplecom_haproxy_1   /docker-entrypoint.sh hapr ...   Up      0.0.0.0:80->5000/tcp
examplecom_tiki_1      /entrypoint.sh apache2-for ...   Up      443/tcp, 80/tcp

There is 1 container running for each service (db, haproxy, tiki) in example.com folder.

Installing database

There is a command line installer available in tiki folder that should be used to install the database. WE CAN NOT USE THE WEB INSTALLER!. The following command installs Tiki database

docker-compose exec tiki php console.php database:install

Scaling containers

If more Tiki container is wanted, the following command launch new containers.

docker-compose scale tiki=3

Now, the following containers will be listed on docker-compose ps:

        Name                      Command               State          Ports        
------------------------------------------------------------------------------------
examplecom_db_1        docker-entrypoint.sh mysqld      Up      3306/tcp            
examplecom_haproxy_1   /docker-entrypoint.sh hapr ...   Up      0.0.0.0:80->5000/tcp
examplecom_tiki_1      /entrypoint.sh apache2-for ...   Up      443/tcp, 80/tcp     
examplecom_tiki_2      /entrypoint.sh apache2-for ...   Up      443/tcp, 80/tcp     
examplecom_tiki_3      /entrypoint.sh apache2-for ...   Up      443/tcp, 80/tcp
