Kontena Deploy is a powerful new feature for defining and running complex applications with Kontena. It may be used to define a multi-service application in a single file including all necessary settings and environment variables. An application described in any such file can be started with a single command
kontena deploy that takes care of everything for you: scheduling services across cluster, pulling required images, linking services and more.
With Kontena Deploy, the typical workflow for starting a new application is as follows:
- Describe your application with
- Optionally, configure your application environment with
- Finally, start your application with
In order to understand how Kontena Deploy works, let's get started with a simple Wordpress example.
First, we will describe our application by creating a
wordpress: image: wordpress:4.1 stateful: true ports: - 8080:80 links: - mysql:wordpress-mysql env_file: wordpress.env mysql: image: mariadb:5.5 stateful: true environment: - MYSQL_ROOT_PASSWORD=secret
Next, we will set the configuration for our
wordpress service by creating a
wordpress.env file. Alternatively you can set all required configuration variables in
kontena.yml file (like in our demo video above).
WORDPRESS_DB_HOST=wordpress-mysql.kontena.local WORDPRESS_DB_USER=root WORDPRESS_DB_PASSWORD=secret WORDPRESS_AUTH_KEY=secret WORDPRESS_SECURE_AUTH_KEY=secret WORDPRESS_LOGGED_IN_KEY=secret WORDPRESS_NONCE_KEY=secret WORDPRESS_AUTH_SALT=secret WORDPRESS_SECURE_AUTH_SALT=secret WORDPRESS_LOGGED_IN_SALT=secret WORDPRESS_NONCE_SALT=secret
Finally, we will run
kontena deploy to deploy our complete application into Kontena Grid we are currently logged in.
