Pass environment variables to Azure container instance

In my last post, I created a wordpress on Azure container instance. And I used Azure database for mysql as the database.

The reason I chose to use Azure database is that it's cheaper than docker container.

But it doesn't stop you to use a docker container as a database server.

Here is how you can create a mysql server in docker. 

az container create --name tempmysql --image mysql -e MYSQL_ROOT_PASSWORD=yourpassword --resource-group testACI --ip-address public --port 3306 

environment variables and start up command are well supported in  Azure container instance.
