Setup local docker-compose install

[jeffcullis]

Working through the docker-compose setup instructions in the current dockerinstall branch.

Using Windows install via WSL2 (Ubuntu)

Following steps here:
https://github.com/cioos-siooc/cioos-siooc-wordpress/tree/dockerinstall

Setup .env file as specified.

Ran docker-compose up.

• PHP admin page and login worked
• The WP-CLI failed to start.
• Wordpress had an error stating it couldn't find versions.php.

Connected to WP container and linked in the fixed location of the wp-includes:
ln -s /usr/src/wordpress/wp-includes/ /var/www/html/wp-includes

After this could start WP. However

• Could not open http://example.test in browser (but curl http://example.test within WSL does work)
• Opening localhost in the browser showed a database error.

Added a couple of changes to the docker-compose.yml based on
https://stackoverflow.com/questions/50999848/how-to-run-wp-cli-in-docker-compose-yml

Trying the sample WP CLI command failed stating that a path needed to be specified. However adding the 'command' line specified there still did not start.

Next tried running an updated docker-compose command:

$ docker-compose run --rm wpcli wp core install --path="/var/www/html" --url=http://example.test --title=test --admin_user=<username> --admin_email=<email>
Creating cioos-siooc-wordpress_wpcli_run ... done
Error: Error establishing a database connection. This either means that the username and password information in your `wp-config.php` file is incorrect or we can’t contact the database server at `mysql`. This could mean your host’s database server is down.
ERROR: 1

Noticed that the wp-app/wp-config.php contained a different DB password from my .env, so updated it to match. However after docker-compose down/up it still failed. The wp-config.php also has 'db' as the DB_HOST setting, so not clear why it is trying to connect to 'mysql' instead.

However afterwards going to localhost in browser took me to the WP install menu:
http://127.0.0.1/wp-admin/install.php
After going through the install I see the WP hello world page at localhost.

Seems I just needed to copy the 'environment' section from the wp section to the wpcli section in the docker-compose.yml, and then the WP CLI commands work as expected.

I don't know if the version.php is a WordPress error. It doesn't come with that file - was there a plugin in the install?

WPCLI doesn't run normally, because it's not something that turns on, and persists. In that file you linked, they include an install command to make WordPress install on compose-up, which is cool. That would eliminate step 5 in my setup.

There is a lot going on on these docker setups, and I hope it runs smoother for you next time

Thanks for reporting!

No problem, I figured it could be a bit involved getting it to run in a different environment than you used.

Here's the commands I wound up needing for the composer and npm install of the theme:

(base) jcullis@... $ pwd
/home/jcullis/docker/cioos-siooc-wordpress/wp-app/wp-content/themes/cioos-siooc-wordpress

# Install nvm, node
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
$ nvm install --lts

$ sudo apt update
$ sudo apt install php7.4-cli
$ sudo apt install php-xmlwriter

# PHP composer install - followed instructions here:
# https://www.jeffgeerling.com/blog/2018/installing-php-7-and-composer-on-windows-10-using-ubuntu-wsl

# Once composer and npm installed, run:
$ composer install
$ npm install
