Maintenance
Shell Access
For debugging and maintenance purposes you may want access the containers shell.
docker exec -it (whatever your container name is) bashLocal Development / Changing Site Name & Ports
Wordpress assets are delivered by means of the initial Site URL, and if you wish to develop locally or on a different port you will experience strange results. If you are performing local development then you would want to setup your environment variables as such:
ENABLE_HTTPS_REVERSE_PROXY=FALSESITE_URL=localhostSITE_PORT=8000(or whatever port you are exposing)
When you are ready to deploy to a production URL - you would change it as such:
ENABLE_HTTPS_REVERSE_PROXY=TRUESITE_URL=www.domain.com
The system will rotate the URLs in the wordpress configuration files and database automatically upon restart of the container.
Command Line
If you wish to use the included wp-cli tool to perform maintenance use it as such:
cd /www/wordpress
wp-cli <argument>Support
These images were built to serve a specific need in a production environment and gradually have had more functionality added based on requests from the community.
