(Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format. We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright {yyyy} {name of copyright owner} 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # traefiked-wordpress 2 | 3 | This *example project* will create four services in a Docker swarm mode cluster: 4 | * Two Wordpress services for two different wordpress sites (beluga and humpback), with labels for Traefik to load-balance 5 | * One MariaDB database configured for Galera-based clustering using swarm mode DNS for discovery 6 | * One Traefik proxying/load balancing container 7 | 8 | Note this is for demonstration purposes, only. To use this in 9 | production, data for Traefik, WordPress, and MariaDB needs to be 10 | stored in appropriate durable Docker Volumes 11 | 12 | # Usage 13 | 14 | These services can be started using the following command: 15 | 16 | ``` 17 | docker stack deploy --compose-file docker-compose.yml traefiked-wordpress 18 | ``` 19 | 20 | This will bring up 2 wordpress containers, a single dbcluster 21 | container, and a traefik container. 22 | 23 | ## Testing 24 | In this example, Traefik is configured to provide hostname-based 25 | HTTP proxying for 2 WordPress sites: beluga and humpback. You'll 26 | probably need to edit your hosts file to define these 2 hosts, 27 | probably to 127.0.0.1 if you are running the composition locally 28 | through Docker for (Mac,Windows,Linux). If you're running the stack 29 | somewhere other than on your local machine, hopefully you'll know 30 | the IP address that you're connecting to, and can use that in your 31 | hosts file. Rackspace has a nice set of instructions 32 | [here](https://support.rackspace.com/how-to/modify-your-hosts-file/) to 33 | edit your hosts file for various OSes. 34 | 35 | When finished, the following command shuts everything down: 36 | 37 | ``` 38 | docker service rm traefiked-wordpress_dbcluster traefiked-wordpress_beluga-wordpress traefiked-wordpress_traefik traefiked-wordpress_humpback-wordpress 39 | ``` 40 | 41 | # References 42 | This project uses the following Docker images: 43 | * PHP 7.1/Apache version of the [Official Docker Wordpress image](https://hub.docker.com/_/wordpress/) 44 | * ToughIQ's [MariaDB Galera Cluster image](https://hub.docker.com/r/toughiq/mariadb-cluster/) 45 | * The [Traefik](https://hub.docker.com/_/traefik/) load balancer 46 | -------------------------------------------------------------------------------- /docker-compose.yml: -------------------------------------------------------------------------------- 1 | version: '3' 2 | services: 3 | traefik: 4 | image: traefik:v1.2.0-rc2-alpine 5 | networks: 6 | - traefik 7 | ports: 8 | - "8080:80" 9 | - "8443:443" 10 | - "8090:8080" 11 | volumes: 12 | - /var/run/docker.sock:/var/run/docker.sock 13 | # Before running something like this stack in production, make sure you store both your Traefik toml config 14 | # file and acme.json in a durable volume that's mounted in the container: 15 | # - /data/traefik/config:/etc/traefik 16 | command: traefik --web -l DEBUG --docker --docker.swarmmode --docker.watch -c /etc/traefik/traefik.toml 17 | deploy: 18 | placement: 19 | constraints: 20 | - node.role == manager 21 | beluga-wordpress: 22 | image: wordpress:php7.1-apache 23 | ports: 24 | - "80" 25 | networks: 26 | - traefik 27 | - db 28 | depends_on: 29 | - dbcluster 30 | deploy: 31 | replicas: 1 32 | update_config: 33 | parallelism: 1 34 | delay: 10s 35 | restart_policy: 36 | condition: on-failure 37 | labels: 38 | - "traefik.frontend.rule=Host:beluga" 39 | - "traefik.docker.network=traefiked-wordpress_traefik" 40 | - "traefik.port=80" 41 | environment: 42 | WORDPRESS_DB_HOST: "dbcluster" 43 | WORDPRESS_DB_NAME: "wordpress" 44 | WORDPRESS_TABLE_PREFIX: "beluga" 45 | WORDPRESS_DB_USER: "wp" 46 | WORDPRESS_DB_PASSWORD: "changemetoo" 47 | humpback-wordpress: 48 | image: wordpress:php7.1-apache 49 | ports: 50 | - "80" 51 | networks: 52 | - traefik 53 | - db 54 | depends_on: 55 | - dbcluster 56 | deploy: 57 | replicas: 1 58 | update_config: 59 | parallelism: 1 60 | delay: 10s 61 | restart_policy: 62 | condition: on-failure 63 | labels: 64 | - "traefik.frontend.rule=Host:humpback" 65 | - "traefik.docker.network=multi-site-proxy_traefik" 66 | - "traefik.port=80" 67 | environment: 68 | WORDPRESS_DB_HOST: "dbcluster" 69 | WORDPRESS_DB_NAME: "wordpress" 70 | WORDPRESS_TABLE_PREFIX: "humpback" 71 | WORDPRESS_DB_USER: "wp" 72 | WORDPRESS_DB_PASSWORD: "changemetoo" 73 | dbcluster: 74 | image: toughiq/mariadb-cluster 75 | networks: 76 | - db 77 | deploy: 78 | replicas: 1 79 | update_config: 80 | parallelism: 2 81 | delay: 10s 82 | restart_policy: 83 | condition: on-failure 84 | environment: 85 | DB_SERVICE_NAME: dbcluster 86 | MYSQL_ROOT_PASSWORD: changeme 87 | MYSQL_DATABASE: wordpress 88 | MYSQL_USER: wp 89 | MYSQL_PASSWORD: changemetoo 90 | 91 | networks: 92 | traefik: 93 | driver: overlay 94 | db: 95 | driver: overlay 96 | 97 | --------------------------------------------------------------------------------
