test-wordpress-bitnami

This repo contains the Docker Compose setup for the Bitnami-powered WordPress instance with SSH access and wp-cli installed. Can be run easily behind Traefik.

Once docker-compose up -d is run (and the MySQL and WordPress is set up for the first time) you can:

curl 0.0.0.0:8888 -s | grep -i generator

Customize

You can provide some env variables via .env file:

• SSH_PASSWORD (defaults to p4ssw0rd)
• WORDPRESS_DATABASE_PASSWORD (defaults to p4ssw0rd)
• WORDPRESS_SITE_URL (defaults to http://localhost:8888)
• WORDPRESS_HOSTNAME (used to add routing label for Traefik, e.g. wptest.myself.dev)
• WORDPRESS_HTTP_PORT (defaults to 8888)

You can use head -c 500 /dev/urandom | md5 | base64 to generate them.

wp-cli

wp-cli tool is installed in both WordPress and SSH containers.

$ docker-compose exec ssh-dev wp post list
+----+--------------+-------------+---------------------+-------------+
| ID | post_title   | post_name   | post_date           | post_status |
+----+--------------+-------------+---------------------+-------------+
| 1  | Hello world! | hello-world | 2022-09-08 11:55:08 | publish     |
+----+--------------+-------------+---------------------+-------------+

Automated posts publishing

Call ./publish.sh from your crontab:

17 */4 *   *   *     /path/to/publish.sh 2>&1 | tee -a $HOME/publish.log

Make sure $PATH is properly set up in the crontab.

Debugging

You can access the running WordPress container via:

docker-compose exec -i wordpress bash

And use SSH to get access to the WordPress file:

ssh wordpress@0.0.0.0 -p62222 -i ssh_key

openssh-server:~$ ls -lh /opt/bitnami/wordpress | grep '/bitnami'
lrwxrwxrwx  1 wordpress root        32 Sep 13 12:08 wp-config.php -> /bitnami/wordpress/wp-config.php
lrwxrwxrwx  1 wordpress root        29 Sep 13 12:08 wp-content -> /bitnami/wordpress/wp-content

Files and permissions

• The WordPress instance is located at /opt/bitnami/wordpress.
• WordPress files are owned by wordpress(1001):root.

Regenerate OpenSSH public key

ssh-keygen -t ed25519 -f ssh_key -N ''

Behind Traefik proxy

This container is ready to be put behind Traefik.

1. Clone the repo and run the Traefik container.
2. Change your WordPress install to use https:

WORDPRESS_HTTP_PORT=8181
WORDPRESS_SITE_URL="https://<your domain, e.g. test.myself.dev>/"
WORDPRESS_HOSTNAME=<your domain, e.g. test.myself.dev>

3. The requests reaching your WordPress container will be using HTTP (TLS is terminated at the Traefik level). So make sure to pretent that WordPress is handling https requests to avoid redirect loops:

// Add this to your wp-config.php
// ...
// fix redirects loope when accessing /wp-admin and wp-login.php
// https://wordpress.stackexchange.com/questions/170288/force-ssl-admin-not-working
define('FORCE_SSL_ADMIN', true);

// a comma-separated list e.g. http,https
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false) {
       $_SERVER['HTTPS']='on';
}
