Connecting to a mysql running on a Docker container · Issue #95 · docker-library/mysql
Frankly, this forum page has no consensus on a solution to this issue. Nevertheless, what worked for me on my set up with running MacOS as the Docker host and running a container with: Ubuntu 16.04 and MySQL 5.7 is the following:

1) Within the container: change in /etc/mysql/mysql.conf.d/mysqld.cnf the bind-address option from to
2) Restart MySQL server (note that whenever you start MySQL you must use this command in the Dockerfile:

RUN sed -i -e"s/^bind-address\s*=\s* =" /etc/mysql/mysql.conf.d/mysqld.cnf
RUN find /var/lib/mysql -type f -exec touch {} \; && service mysql start

That is, you must touch the files in /var/lib/mysql and then start the server with service command and not systemctl.

Next, create a user separate from root e.g. dev_1, in MySQL and given them privileges to their '' and '%' hosts. Like this in the Dockerfile:

RUN find /var/lib/mysql -type f -exec touch {} \; && service mysql start && mysql -uroot -proot mysql -e "GRANT ALL ON *.* TO root@'' IDENTIFIED BY 'secret' WITH GRANT OPTION; CREATE USER 'dev_1'@'' IDENTIFIED BY 'secret'; GRANT ALL ON *.* TO 'dev_1'@'' IDENTIFIED BY 'secret' WITH GRANT OPTION; GRANT ALL ON *.* TO 'dev_1'@'%' IDENTIFIED BY 'secret' WITH GRANT OPTION; FLUSH PRIVILEGES;"

Then when you start the container you must publish the port number like so:

docker run -t -d -p 4406:3306 ubuntu_16_04_lemp_php_7_2:latest

If your container stops prematurely, then you might want to add a CMD line in your docker file to run a start.sh script and within that script you might want to add something like this:

# stupid hack to keep container from being stopped
tail -f /dev/null

Finally, to connect to your DB instance on your local MacOS machine with an app like Sequel Pro for example, use the following credentials:

Username: dev_1
Password: <dev_1_password>
Port: 4406

If you don't like to use port 4406, try 3307, 3308, 3309.

Ecommerce University | Contact Form Country/Province Dropdown - Shopify Design
The short of it is: if you are using shopify's country_option_tags variable you'll need to include the 'shopify_common.js' | shopify_asset_url | script_tag JavaScript library to be able to dynamically populate the province / state field. Look to the Shopify Debut theme to see how this is done.

Ecommerce University | Sort &quot;All Products&quot; collection by product type - Shopify Design
An example of how to sort all products in a collection array, by a certain attribute. For example, if you wanted to sort by the dates that products were published at you could use this attribute: 'published_at'. Note, that you have no option by which to sort, so it's always ascending. So if you want descending then you need to pass the '| reverse' array filter.

Ecommerce University | Shopify - using if statements within js.liquid files - Shopify Design
This forum contains a good explanation of why certain liquid template keywords like: {{ template }} do not return what you expect in .js.liquid files. So don't use it to try to detect the template from within the .js.liquid files. Instead, in the theme.liquid template, in the head tag do something like this:

var template = {{ template | json }};

and then use that variable in your JavaScripts that you include externally, like so:

if(template === 'index'){
console.log('homepage loaded');
